Database Info

for those that dont want to root

it would be awesome to start a thread with all the information in one place someone would need to maximize the phones potential without rooting it or wrecking the warrenty. i know i will end up rooting my phone but not right away. so im looking to maximize it without doing anything too crazy. so what should i know and what free programs should i get to do this.
thanks so much

Droiddog and places like that have recommended apps and such if you want to stay stock. XDA is a place for modding. Its great that you're learning and on your way.
Remember, that you can always go back to stock for warranty issues with oden. Once you flash, you never go back.

When searching for captivate stuff, I found most information (even not related to rooting) on this forum.
For my stock captivate I got:
Advanced Task Killer - the free ad based one. I have not tried the auto kill levels since I am scared that my phone will turn off randomly when I want to receive a call.
Launcher Pro - the free one (so i can customize the 4 buttons at the bottom of the home screen)
Home Switcher - so i can switch to touch wiz launcher if I want to use the Kies mini app
Google Map - I heard the one that came on the phone wasn't as good as the one in the app store.
I removed all the AT&T Apps from the home screens.
For music I got double twist to sync music with my iTunes.
I tried the AT&T video/music players and PowerAMP and DoubleTwist and something else but none are really that good - They seem to forget which podcasts I already watched/listened to and are not really good at resuming. This is probably because they think podcasts are songs.
I got Pod Manager to download podcasts - worst UI in the world but gets the job done. I am still almost thinking of using itunes and just syncing with double twist every morning.
The battery isn't the greatest on this thing. Not sure what techniques I can use to make it better. I set my background to black but not really sure if that will help. Also I used the "Power widget" to dim my screen a bit. I really wish I could use the "auto" setting on the light but still tell it to be darker in general. To offset the power even more I bought a couple micro usb cables. 1 for computer, 1 for car, 1 for work computer, and power adapter from box for next to bed. However I had to cut down some of the plastic off the ends of the cable to make it fit. I do generally make it all day with just the nightly charge even when I watch a podcast on the way to work and home from work (about 1 hour each way) on the bus but I like having the cables just in case.
The Kies app and mini app seems to suck - I can't get either of them to work on win 7 x64 even with .net 4.0. On windows 7 x86 the mini version used (without .net 4.0) to work but not anymore since the latest kies mini update.
Other than that I just got a bunch of games and apps. Although it probably based on personal preference.
Hope that starts you off in your quest.

If you want awesome battery life un-install all that crud( launcher Pro, ATK, fancy music player) use any wallpaper you want and toggle your background data and wifi notifications my cappy gets 12 hours easy.

Oh sorry I was considering 12 hours (10 hours of sitting in pocket use + some phone calls + 2 hours of video playing) poor battery life.
I picked the black background because I heard the "Live Backgrounds" were a battery drain and I like the black color (its my PC's background color as well).

Auto Task Killer is not needed...does more harm than good IMO.
Also your black background is the best for Super AMOLED (all OLED-based) displays because when a pixel is black it is essentially using no energy.

-Battery life gets better with about 2 weeks of use
-I uninstalled all task killers. This thing multitasks on its own fine
-I figure a full day without plugging into a charger is excellent on any smartphone device.
-However, I bought the samsung external charger and battery on amazon, so I now seldom plug my phone in. I just swap batteries in the evening and charge the battery thats been in the phone all day

My captivate is 1 week old. The battery the first few days was not very good but now it seems to last longer.
This is what I have done:
1- Brightness set the lowest (Phone + Browser) I can see the screen just fine.
2- Black background, but with style so it doesn't look plain
3- All apps. sync manually and background data off. I turn it on when I need it but I am most of the time on wifi.
4- GPS off, I don't need it or use it
As of right now, with moderate use, I am on my 2nd day without charging and I'm pretty sure I will get a 3rd day without charging.
Apps that I can recommend:Fancy Widget,SamServmode, Barcode Scanner, 3G Watchdog

My post about droiddog was about the app reviews and such they do. Basically all unrooted android phones are the same, just different hardware. That's why general android sites are best for unrooted phones. Samsung support forums would be a good place. General public troubleshooting each other. Get where I'm going with this?

oh why didnt you say that If I were you I would buy an ipod touch for video playing and your battery in your phone will last for 20 hours.

I resisted rooting for the longest time, thinking I'd wait till Froyo.
I finally got tired of waiting and did the one click root + lagfix. Didn't try anything else yet but let me tell you, just doing that small amount has made my Captivate experience so much happier

Do you have the link to the oclf you used? I'm just afraid of bricking it. I need to root first then I can use the oclf? Our does the oclf do it all?
Sent from my SAMSUNG-SGH-I896 using XDA App

with my usage, my phone lasts me 8 hours, if im lucky. sometimes i go to class at 12 get home by 3 and im at about 60% lol..

Don't use OCLF. Use z4root, it works with 2.2

Green Power vs JuiceDefender

Hello everyone!
I was just wondering between these two apps...
Which one works better for you and if will be great if you can share your configuration!!
Also, does anyone knows is any of these two disable whatsapp and gmail notifications?
Many thanks for sharing!
Cheers!

IMHO
I can answer about Green Power Premium:
It doesn't have such option like disable notifications. He does such thing like disables data connection for amount of time you chose (for me it is 15min) and then enables data connection for amount of time you choose (for me it is 2min)
Now my Galaxy Note works 2 times longer (from 10h to 20h)

WOW! double time!!
thanks for sharing!

I have been trying both, and while both of them seem to deliver a noticeable reduction in power draw (actually in my case a dramatic reduction), of the two I'd have to give my vote to GreenPower (I'm using the full version). The power reduction is at least as good as Juice Defender Ultimate, and the premium version is significantly cheaper.
Both work by turning various features (mainly Wi-fi/3g/BlueTooth) on and off automatically, but as result can cause delays in things like receiving push-mail and that kind of thing. With Juice-Defender I found this to be quite noticeable, but I'd have to say that with Green-Power I haven't really noticed it slowing down messaging or anything else.......

I've used them both - and deleted them both. I'd rather manage power myself.

i am using 2x Battery for me this is the best. simple and clean.

I usually use JuiceDefender but decided to try out Green Power. I really like it but I have a hard time getting my phone to sleep properly on GP.

i use widgetsoid and just enable my connection when i want it (wifi/3g)
i could never find the proper app that did exactly what i wanted- rather just have control.
going that was and using the phone an average amount my battery goes from 100 -> 75 from the time i wake up (7am) to the time i got to bed (12-1 am)
the 2500mah battery is pretty good!

With JuiceDefender I can get my phone to sleep 95%+ of the time but with GreenPower, my cpu is only sleep 40%+. Can anyone give me tips to get my cpu to sleep more to preserve battery?

Just out of interest, what happens when you browse the web and GreenPower has turned off the Data Connection?
Or you're watching a youtube video and it decides its time to turn off data?

Tried both versions and found green power premium to work better for me. (Price was a good point too.)
However the next day I found that if I left my phone for a while (Around 1 1/2 to 2 hours), the display would not turn on and If I called the phone it would not ring. Only way to fix this was to press the power button for 10 seconds to reset the phone.
Uninstalled green power to see if this was the cause and hasn't happened since.
Was wondering if something similar has happened to other people?

I had to go back to JuiceDefender since I couldn't get my phone to go into deep sleep with GreenPower.

Hi, i went for Green Power. I found it simpler to configure, more focused on the job. Juice Defender has to much possible settings and complexity, this makes it a great tool but might also lead to poor efficiency.

I have never used green power before but im on juice defender. I have experienced auto turn off by the note due to a set cpu settings that govern lower clock to cpu at a certain condition. Due to the big display on note i think lower cpu clock wont do it. Because of that the device turned off itself. Upon failure to operate. Hope this solves your problem

I have tried JuiceDefender but ultimately prefer to do everything manually. Some how I always feel the auto manage apps will have everything off precisely when you need it. I use the SwitchPro widget to quickly enable/disable the various radios from my home screen and it works great.

@ Aldragor
I have/had the same problem. In the beginning I thought that my launcher would be the cause for this problem, but after I disabled my Green Power Premium it hasn't happend since now.

Juice defender ultimate, the feature of switching 2g 3g on stock ROM alone was worth the price!

After figuring out how to config GreenPower properly, I went back to it.

I used JuiceDefender and thought it was great.... when it worked. However, I used it mostly as a scheduler with about 15% battery saving which I took as the icing on the cake.
I want all connections on during the day (peak) so I can take skype calls, etc.. When I'm home, I just want to periodically check for mails, etc (so have connection enable every 15min) and when I go to bed I don't want to be disturbed by emails, messages, etc but still want phone/sms on in case there is an emergency. And most of all, I didn't want to have to manually do that every day.
Problem was that it never really stuck to the schedules. This was the ultimate version but it was a crack as they never offered the ultimate on a trial. I wanted to evaluate the ultimate and buy if it did the job. So, it might have been a bad crack which caused the problem, but I guess I'll never know as I don't want to risk wasting the money if the schedule problem persists.

I am a lover of juice, it keeps he juice in and right

General Joying Intel Sofia - All you need to know - micro tutorials - Q&A

Revised 1-Mar-2018
I've updated the writings a bit for the 1 Sept firmware update.
In case you are wondering I have this unit : Joying EU-JY-FL121N2
01. It is worth the upgrade from Androd 5 to 6?
For me this things determined me to update
1. Split screen - you can put side by side 2 apps, not all apps work but most do. (does not work with 1 sept firmware)
On Android 6 the split screen it known to be buggy but for me it worked ok, i find it useful putting Waze and PlayerPro side by side. iGo does not support split screen if you wonder.
When the units enters sleep it "forgets" which apps were in split screen so next time the HU wakes up you need to set those 2 apps again in split screen. It does not take long but if you do it on a daily basis it gets annoying... quickly.
2. Better CPU management and with that comes a bit better CPU power management (less heat generated for basic tasks, like playing music)
3. The notifications background is not white anymore with the white text on it... it's how it is supposed to be... dark gray so you can read the white text
Later edit :
I been through all the Android 6 releases and I can tell you that it still does not feel as stable as it was on Android 5. There are many times when I felt sorry that I've upgraded to 6. I would downgrade to 5 in an instant if it would be possible. The unit bad implementation of the sleep behavior it really bugs me.
Ranting more on the subject here : https://forum.xda-developers.com/showpost.php?p=72726651&postcount=47
L.E. 25 July offers the best stability so far, can't recommend the 1 sept update : read here
02. The mods of Android 5 are updated for Android 6 - 21 Sept (the latest at the time of writing)
Yes ! All of them.
03. Are there any custom roms for the Joying Intel Sofia ?
Yes ! Finally ! Thanks to @gtxaspec and @surfer63 we have this :
https://forum.xda-developers.com/an.../rom-gtx-joying-stock-rom-2018-01-29-t3742482
04. Deezer white bar issue : This bug presents itself on android 6 only. Deezer has a white bar in player mode, annoying at night and ugly looking. Contacted Deezer, they promised a fix that never came, it’s been a month. Contacted Joying, they told me that they can’t do anything about it. Tested a lot of Deezer versions and found out that the version 5.3.11.90 is the newest that does not have the bug.
LE : they still haven't fixed it and wrote them 5 times already... they promised each time... they value my input... yeah, right.
L.E.E - 2018: kept writing up tickets latest was 2 weeks ago... they are still looking into was the answer.... for more then 1 year i must add... very poor user support,
05. XiiaLive Pro issue : If the unit has the server no-kill mod installed, XiiaLive Pro has FFmpeg as the decoder (this is set by default), you put the app on pause and send the unit to sleep (turn off the engine), for some unknown reason the unit start to drain 0.15A instead of the default 0.01A and after a few minutes of sleeping it shuts down. You NEED to change the decoder from FFmpeg to Android to solve the problem.
LE : They pretty much abandoned the development. This app has some issues, a big one being that when another music app steals the audio focus the Xia app does not pause or stop and continues to stream in the background, eating data for no reason. Wrote them a few times... nothing...
06. What is the unit default DPI? Everything seems so small coming from my old unit.
The default DPI is 160. If you set the DPI to 161 some apps will change the look of the interface (tablet - phone)
L.E. - this can be solved with the help of the @gtxaspec custom ROM or installing Xposed and AppSettings mod via JET app made by @surfer63
Unfortunately once you change the unit DPI from the default 160 to anything else, say 200, some of the default apps do not scale well and the notification bar grows in thickness a lot (taking a lot of screen estate) so I recommend a restart after each DPI modification to see how the android UI looks and also you need to check all the apps to see if there are badly affected by the DPI change.
You can set the DPI via adb like this (you need to have adb installed) :
adb kill-server
adb connect IP (exemple : adb connect 192.168.1.55)
adb shell wm density xxx (xxx being the density number for example 180 or 190 or 200 or 220 )
07. After the update the unit shuts down instead of sleeping what shall I do:
This unit has some kind of power monitoring, if an process or an app hangs the unit, draining more power then it should while it's in sleep mode it shuts down the unit in order to protect the car battery from draining completely.
Most of the people that upgraded the unit (from android 5 to 6 or from one build of android 6 to another build of 6) without wipeing the data had various problems so updating this unit is not an option in my opinion with a proper wipe, no matter the firmware or version number.
For trouble free, smooth operation you MUST do the following: (revised 05-sep-2017)
1. backup data
2. take out all the microsd cards, usb sticks and check them all for errors (some users had problems with data corruption on the cards that they kept in while updating)
3. delete ALL the files from the internal storage (with the default file manager, go to internal storage, select all, delete)
4. wipe the unit / reset the unit to defaults from the settings
5. before flash the new firmware (again) let the unit cool down at least 30-45 minutes because without additional cooling it overheats and the CPU throttles all the way down to 416Mhz (processing everything extremely slowly) preventing the unit to successfully finish the firmware update. The updating is on a timer and once the timer is out the unit reset itself even if it did not finish the update. And you might find yourself in an endless loop and in some rare cases people got their units bricked. I've never had any problems because I update my units at home and while they are on my desk I take the lid off and put an big fan to blow over the components to cool everything down.
6. wipe it again / reset the unit to defaults from the settings (this is optional)
7. test the sleep function (to see if the unit without any additional software installed behaves ok)
8. put everything back / reconfigure (I personally prefer not to restore from a Titanium backup and reinstall everything and reconfigure)
9. test the sleep function again (to see if the unit is still ok after all that you installed or moded)
10. before inserting back the old microSD cards and usb sticks in the new reflashed/reinstalled unit, make sure that are no files on them from the previous installation (files left over by apps from the the previous installation)
It's always a good idea to start clean and delete the leftovers files that sometimes could be damaged and once you put the back you might encounter problems.
08. I’ve just upgraded my unit and it feels slow, slugish?
Follow the above tutorial except step 7 and 9
09.I can’t turn off the screen/touch BEEP, it’s annoying! Help !
Solution 1
BEFORE flashing or reflashing edit the file “config.txt” from the root of the update
And change this line "ro.fyt.amp_switch=1" to this "ro.fyt.amp_switch=0" (it sets the AMP Enable to OFF by default)
Solution 2
1. Enter Car Settings app
2. Go to the bottom right tab (the one with the screwdriver on it) ckick it and enter 3368
3. go to the AMP Enable option and turn it OFF
4. go to the EQ menu (second bottom tab from right to left) from the Car Settings and now you have Keypad Tone option and you can turn it off.
10. After update, adb via wi-fi does not work anymore.
Solution 1: by @gtxaspec
Before flashing edit the “config.txt” (in the root of the firmware) and add this line without the quotes “service.adb.tcp.port=5555”
Solution 2 : by @gustden
1) download a terminal program ( Terminal Emulator for Android )
2) enter the following command: setprop persist.adb.tcp.port 5555
3) reboot
Solution 3 : mod by @AssassinsLament
In order to be able to do anything on the unit via ADB you NEED to enable ABD over Wi-Fi so download AoW_v1.0.apk from here https://forum.xda-developers.com/showpost.php?p=71616884&postcount=273 , copy the apk to a stick, run it in the unit and let it do it's job. (you can uninstall it at the end but I advise you to keep it and disable the ADB Over Wi-FI for security purposes)
11. I need to root what shall I do?
The mod credit goes to @surfer63 !
1. Go to https://github.com/hvdwolf/Joying-RootAssistant
2. go to the green button "Clone or download" and choose Download ZIP, download the file
3. create folder c:\rootjoy and unpack the zip there
4. connect to a router (home or phone router), and check what IP your headunit has (something like 192.168.1.34)
4. open an command prompt with admin rights
5. type the following without the quotes
- "cd c:\rootjoy"
- "cd SuperSU_for_Joying_Intel"
6. at this point restart the unit, once it has booted enter next line (don't let the HU IDLE too long once it has booted because you will get disconnect errors)
- copy_install.bat IP (example copy_install.bat 192.168.1.34)
- if there are no errors, reboot (I followed the steps above and never failed)
7. you are now rooted
Later edit : @surfer63 moved files around and the repository adress from point 1 is at : https://github.com/hvdwolf/Joying-RootAssistant/releases/tag/20170617-02
I haven't tested rooting with the new archive
Later edit 2 : @surfer63 put up a nice tutorial here : https://hvdwolf.github.io/Joying-RootAssistant/rooting.html
12. The default EQ and overall sound quality is poor, can I do anything to improve it?
Solution 1
Viper4Android : brought the sound to life for me, without it the sound quality is poor. With this software you can improve it quite a lot. The unit NEEDS to be rooted so you have to follow the above tutorial and root the unit first in order to install the Viper.
01. go to this post https://forum.xda-developers.com/showpost.php?p=72064749&postcount=41, download the viper.zip file.
02. For the me last version of the Viper4Android (included in the viper.zip) works ok but the EQ section is broken for me (meaning changing the EQ modifies the sound just slightly) so I used an older version of Viper4Android where the EQ section actually works and you can clearly hear the difference when playing with the EQ bars.. If you want to use my version go to to step 12 if you want to install the @AssassinsLament version go to step 03
03. unpack the viper.zip to C:\viper
04. open an cmd prompt with admin rights
05. "cd c:\viper"
06. restart the HU, just to be safe, after the reboot enter the next line in cmd prompt
07. enter "viper.bat IP" (example : viper.bat 192.168.1.34)
08. after it finished reboot the HU
09. after reboot ran the app, say yes when it wants to install the driver, wait, it takes a few minutes, if android wants to end the task press wait, be patient, when it's done reboot again.
10. ran the app again, from the left menu select settings, and lock on the headset profile (because the headset has all the options enabled so more power to you for tweaking the sound)
11. select headset profile and have fun tweaking the sound.
12. unpack the viper.zip to C:\viper
13. go to https://forum.xda-developers.com/showthread.php?t=2191223 scroll down to v2.3.4.0 (Android 2.3~5.0) and download the mediafire link next to it (http://www.mediafire.com/download/cnqqdme51qy9ft4/ViPER4Android_FX_v2340.zip)
14. inside the ViPER4Android_FX_v2340.zip there are 2 files, unpack the ViPER4Android_FX_A4.x.apk to the "c:\viper\viper" folder
15. rename it from ViPER4Android_FX_A4.x.apk to ViPER4Android_FX_v2505_A4.x-A7.x.apk and overwrite the original ViPER4Android_FX_v2505_A4.x-A7.x.apk
16. now you can follow the steps from 05 to 10 pretty much.
Later edit : Unfortunately, the EQ section from the Viper app (no matter the version used) does not work with 25May and 7July firmware, the sound stutters, the music speed slows down in a weird way, there are pops in the speakers.
Currently I am using the Viper only to enhance the bass mainly that you can't do otherwise with the extremely limited default Joying EQ.
My settings are as follows :
Viper Bass to +8db
Viper Clarity to +3.5db
Dynamic System to 10% - High Performance Headphones v1
Solution 2 - by @bogdi1988
You can change the default AMP TDA 7388 chip with the Pioneer PA2030A or the TDA7850
Read here the details:
https://forum.xda-developers.com/android-auto/android-head-units/joying-sofia-chip-upgrade-t3589587
13. Enable “OK Google” from any screen or app possible on this unit?
No, at this time, with this firmware version (25 May) at the time of writing there is no solution.
The velvet.apk works fine, it does not crash, you can OK Google from any screen/app BUT it breaks the unit sleep mode, the unit will shutdown instead of sleeping.
14. In this (25 May) firmware of android 6 is the Google Maps voice finally works with the FM Radio app?
Yes!
15. When I turn off the engine all the apps that are running are closed (killed) while the unit is sleeping.
You need to have a look at this thread for the @gustden mod:
For the 25 May firmware he built the 6.3 version of it’s mod.
All the details and more here :
https://forum.xda-developers.com/an...-units/joying-2gb-steering-wheel-key-t3543390
Later edit : The 6.3 mod still works with 7 July but the guy that worked his magic on the mod did not update the mod for the 7July firmware at the time of writing and it's been away for 1.5 months so I am not sure about the future of the mod
16. I want to enable split screen so I can run 2 apps at the same time.
In order to do that you need to replace the Joying modified Settings.apk with the original android.
We are gonna use the @AssassinsLament script so
1. Go to this post https://forum.xda-developers.com/showpost.php?p=72107737&postcount=109 and download the “4-27-17_Original_5009_20_Settings.zip” file
2. Create the folder c:\replace_settings and unpack the content of the 4-27-17_Original_5009_20_Settings.zip file
3. Create a new folder called c:\replace_settings_temp and unpack the in this folder the contents of the 5009_60.zip file that it’s in the root of the firmware that that you used to flash the unit.
If you don't have it download exactly the same firmware archive that you did to update the unit, unpack it and in the root you will find the 5009_60.zip archive that contains the Settings.apk and Settings.odex that you need.
4. Copy the Settings.apk file that you will find in the c:\replace_settings_temp\system\priv-app\Settings\ to c:\replace_settings\SETTINGS, (overwriting the old one)
5. Also copy the file Settings.odex from c:\replace_settings_temp\system\priv-app\Settings\oat\x86\ to c:\replace_settings\SETTINGS, (overwriting the old one)
6. Now run a cmd prompt with admin rights and enter the c:\replace_settings folder
7. Enter settings.bat IP (IP of the unit, example: settings.bat 192.168.1.55)
8. Reboot
9.Go to settings and to About Tablet option, go all the way down to the Build number and keep tapping it till it tells you that you have become a developer
10.Push back once and now you have a new menu “Developer options”
11.Enter it and at the “Drawing” section there is an option called “Multi-window mode” ENABLE it
12.Now when you push the task switcher (from the notification bar) when the running apps are presented they have some icons on the left and you can decide how the apps will run, full screen, split screen on the right part of the screen, split screen on the left of the screen
17. I want to tether via Bluetooth, is it possible?
Yes with the mod made by @doitright
Solution 1
Go to https://forum.xda-developers.com/an...elopment/bluetooth-settings-launcher-t3504526 and download BluetoothTethering.apk
You can follow the tutorial on that page if you are comfortable with ADB or if can follow mine so :
1. Make a folder (with Root Explorer) named “BluetoothTethering” in “/system/priv-app/
2. Give the folder 755 permissions (long click on the folder to have the folder selected and then go to the upper left to the 3 dots , and from the menu pick permissions then tick the boxes till you get 755)
3. Copy in the newly created folder the BluetoothTethering.apk file and give it 644 permissions
4. Reboot
5. Open the HU default bluetooth app and pair the phone with the HU (I suggest to change the default PIN (0000) to something else for security purposes
6. Start the BluetoothTethering app select the paired phone, enable Auto Connect PAN, push Start Service, also Enable Auto Bluetooth Tethering.
Solution 2
Use this app from the playstore :
Free version : https://play.google.com/store/apps/details?id=com.tomlocksapps.bluetoothtetheringmanager
Paid version : https://play.google.com/store/apps/details?id=com.tomlocksapps.bluetoothtetheringmanager.pro
18. Even at the lowest settings the screen is too bright.
Solution 1
1. Enter the Car Settings app
2. Select the lowest tab on the lower right (the one with the screwdriver)
3. Enter code 3368
4. Scroll towards the bottom and you shall see a option named :”Backlight current adjustment”. I have this menu, some said they don’t have it so my guess is that it depends on the model of the unit … can’t say for sure. (LE : the menu is present if you flash the firmware with a certain file read at no 48 down the page)
5. The pass for the menu is 5768 and here you can define the high and low of the brightness slider from the notification bar (swipe down 2 times). For my unit I have no problem turning the brightness low point all the way to 5 and still I am not quite satisfied by the brightness low level.. Some users complained that if they turn it down to 30 the screen turns black, like in the illumination stops completely and some complained that they can’t turn it back on. So PAY ATTENTION while you play with the sliders… and if something bad happens don’t touch the screen at random in order to avoid pushing the SAVE button… you better reset the unit via RST button and start over.
Solution 2:
You need to modify in the customercfg.txt file that you find it in the root of the firmware before flashing.The file contains these 2 lines :
set-blduty-min=5 -> 5 defines the lowest point for brightness slider
set-blduty-max=100 -> 100 defines the highest point for the brightness slider
For me works perfectly 5 and 100. For some at 5 the illumination turns completely off so they run into issues like “after booting the screen turns off” so you NEED to TEST how low can you go on the slider in the “Backlight current adjustment” manu before modifying the file with the proper numbers.
Solution 3: Software
There are some software solutions for dimming the screen even more by applying a screen filter/overlay:
Warning : It does not play well with SuperSu that has TapJacking protection so while the filter is active the SuperSu does not acknowledge your tapping on it's menus if you want to Grand an app permissions for instance.
There is an option to disable the Tapjacking protection in SuperSu but I would advise not to.
The go to app for me is this : https://play.google.com/store/apps/details?id=com.haxor
19. When I install Google app the launcher crashes.
Yes it does, you can’t do anything about it except changing the launcher before installing Google app or change the launcher to a 3rd party launcher like Nova launcher or the default “launcher” (not Launcher3).
If you have installed Google and it keeps on crashing use the DOT app (if you haven’t disable it) on the screen to get to settings and uninstall Google app, reboot, then change the launcher, then reinstall the Google app.
Later edit - 7july - They finally fixed the problem in the 7 July firmware. I haven't tested personally but from what people wrote on the forum it seems ok now.
@CadillacMike confirms here : https://forum.xda-developers.com/showpost.php?p=73063409&postcount=969
20. Everytime I reboot the unit the FM Radio app starts automatically, can I turn that off.
No, there is no solution on how to take that “feature” down yet
Later edit : @Skinzaholic found this solution : https://forum.xda-developers.com/showpost.php?p=73672935&postcount=251

Joying Intel Head Unit Android 6 Update
https://forum.xda-developers.com/an...ing-intel-head-unit-android-6-update-t3597121

21. Some have the FYT5009 SOM but some have the new FYT6021, what are the differences?
1. both have 2Gb or ram and 32Gb storage
2. the CPU on the FYT5009 has a max clock of 1.041Ghz
3. the CPU on the FYT6021 has a max clock of 1,2Ghz
4. the FYT6021 SOM has a tiny bit better heatsink (shape wise to dissipate the heat) but worse for cooling mods. The heatsink is attached with screws so it's easy to take out and replace the thermal paste (with a higher quality one) between the components of the SOM (CPU, VRM) and the heatsink. It does not have thermal pads between the components of the SOM and the heatsink like the FYT5009 does if you look at the pictures here http://4pda.ru/forum/lofiversion/index.php?t793304-1400.html
5. the FYT5009 has an worse heatsink but way better for a cooling mod because of it's smooth surface (glue a bigger heatsink on it), it also has a big and thick thermal pad under the SOM to move some of the heat to the bottom of the steel case. The heatsink is soldered to the SOM board so it's tricky to open up and replace the thermal paste, but someone did it on the russian forum, user YAM1966 and he claims that he lowered the temp by 13C . More details here : http://4pda.ru/forum/lofiversion/index.php?t793304-1400.html (use google translate)
6. the motherboard that hosts the FYT6021 SoM does not have the 2 video out RCAs like the one that hosts the FYT5009 SoM
If you ask me BOTH SOMs need active cooling. The default heatsink on both is poor and without active cooling the heat builds up very fast to 60-70C.
22. Is there a problem if I flash the firmware made for FYT6021 to the FYT5009?
I heaven't seen anyone doing that for testing purposes so I don't know what happens. I was curious to see if flashing the 6021 firmware onto a 5009 drives the CPU clock to 1.2Ghz but I haven't found any info on it.
Although the SOMs are pretty much the same the motherboards that sit on look different from one model to another (different layout, some extra connectors on the board, missing video outputs) so the MCU's could be a bit different... I would say it's a small chance that you could brick the unit.... I can't tell if it will be permanent or temporary (if in the brick state allows you to you flash it again with the proper firmware)
23. Are there any mods/skins of the default FM Radio app?
Yes. @surfer63 did a very nice work here (with pictures)
https://hvdwolf.github.io/Joying-RootAssistant/RadioMods-examples.html
24. Are there any mirrors to the Joying firmwares?
Yes. @gtxaspec was very kind and hosted some here : http://mirrors.gtxlabs.com/joying/1_Firmware/
But not the latest one....
25. I need a small ADB kit to install and use, where can I find one?
Here : https://forum.xda-developers.com/showthread.php?p=42407269#post42407269
You can find portable (no install needed) and non portable versions also.
26. How much power it drains in sleep mode?
Usually the unit enters sleep in 50 seconds to 1 minute after you turn off the engine. In those 50 seconds to 1 minute the power drain fluctuates from 0.50 to 0.75A. After that the unit drains ONLY 0.012A.
I noticed 2 instances when the sleep behavior changes, can't really tell if it's by design or it's a bug:
1 If you happen turn on the engine in that 50 seconds to 1 minute time frame, before the HU enters sleep, from that moment on the unit will enter sleep only after 5 minutes from the moment the engine is off. In those 5 minutes the power drain fluctuates from 0.50A to 0.75A but mostly in the 0.60A area. After those 5 minutes it enters sleep mode and drains only 0.012A
2. After using Waze and iGo at some point the same issue occurs, and the unit behaves like I described above.
The unit has some fail safes and if for some reason it gets stuck draining more power than it should it shuts down/power off on it's own.
27. How long does it stay in sleep mode ?
Personally I haven't test it for more then 2.5 days and it slept fine 2.5 days without shutting down.. I use my car every day so it rarely sits in the driveway for long periods of time.
Some users said that it shuts down after 72 hours.
28. I am leaving my car in a parking lot of a month, I am afraid that my car battery will be empty when I get back, what shall I do?
If you don't start the car for a a longer period of time and you left the unit sleeping the HU shuts down/turn off at some point on it's own, no one really knows exactly after how much time is needed for that to happen.
To be absolutely sure that the unit drains no power at all and the car battery is safe do this :
1. enter Car settings app
2. Go to the bottom right tab (the one with the screwdriver on it) ckick it and enter 3368
3. Make sure that Dormancy Settings is set to OFF (the unit will power off/shut down when you stop the engine)
In the power off mode the HU it drains 0.00A
29. Why not use the Shutdown button from the notification bar to shutdown the unit ( 2 swipes down) ?
If in the Car Settings app the Dormancy Settings is set to ON, after you pushed the on screen button with the engine still running, the HU turns off the screen and backlight and it drains 0.45-0.60A. After you turn off the engine it enters sleep mode and drains the usual 0.012A. It does NOT shutdown! If you turn on the engine it wakes up in 2 seconds.
30. What about the Standby button?
It is semi-useless in my opinion. It displays the time and the date, white fonts on a black background.... nothing more.
31. Waze hangs when the HU exits sleep
I happened to me in many firmware versions, did not had the time to check how it behaves in the 25May version.
What I did is:
1. install the V6.3-Custom_Keys-Mods.zip made by @gustden from here : https://forum.xda-developers.com/an...-units/joying-2gb-steering-wheel-key-t3543390
2. I've downloaded Notepad++ app to be able to edit the install.sh from here : https://notepad-plus-plus.org/download/v7.4.1.html
2. Edited the launcher.sh with Notepad++ and inserted this
sleep 5
am force-stop com.waze
After this:
98) # ACC_OFF - executes on key off
$pause
In the end it should look like this :
98) # ACC_OFF - executes on key off
$pause
sleep 5
am force-stop com.waze
What is does is after you turn off the engine, it waits for 5 seconds and it kills the waze task. The good thing is that once the units wakes up it launches automatically the last active app, so it starts Waze and it resumes the course if it was interrupted during a course.
32. What app shall I use to edit launcher.sh ?
Notepad++, free, official download site : https://notepad-plus-plus.org/download/v7.4.1.html
33. How fast does the unit start?
1. From shutdown it takes 43 seconds.
2. From sleep it takes 2-3 seconds
My experience : I am using the unit for more then 3 weeks now and the unit never rebooted and it never started in the morning from shutdown.
34. What was your previous unit? Why did you choose this one?
Before this one I had an Witson unit with an RK3066 (dual core 1.6Ghz) with 1Gb of ram and 8Gb of storage, 2 microsd slots, 2 usb ports.
I upgraded to this one mostly for 2 reasons it's instant power on and the XDA support and community. After I bought it, I discovered that it has GLONASS and that was a great addition and it had a bit better GPS signal also a welcomed plus. After that I discovered that the unit can be tethered via bluetooth, a major plus.
The new unit lacks a CD/DVD drive but I don't need one, because I mostly stream music and use Waze... when I am in an area with no cellular coverage I use PlayerPro and iGo/Here. I haven't touched a CD in years also I consider the DVD technology obsolete. The sound quality of the FM Radio on the Joying unit is a lot better than my previous unit but it still lacks badly for me, especially when I listen to music, it lacks the dynamic range, it lacks punch, the clarity needed to be able to enjoy music. For talk shows and news is perfectly fine.
Believe me or not but I haven't really felt that this unit is faster then my previous one probably because I keep my units simple, I have very few apps loaded and running.
35. Have you done any hardware mods to your unit?
Yes. I could not stand the high temperatures of the CPU and the throttling on a hot day so I glued (with the help of Arctic Alumina thermal adhesive) some small heatsinks on top the (default) smooth aluminium heatsink to help dissipate the heat more efficiently and soon after I added a few more taller heatsinks for an even better efficiency. All that helped till a certain point where the heat buillt up in the steel case and remains trapped there heating everything up pretty nicely. So I drilled a lot of holes into the top of the case and mounted an low power, low noise high quality fan (Noctua NF R8 redux 1200). The fan sucks the air into the case and slowly cools down the internals.
36. Is there a way to start Google Maps with a darker theme at night to search for a place?
Yes! I was also bothered that when I start the Google Maps at night time, it welcomes me with a blinding white-gray map. Once you plot a course it enters navigation mode, checks (via gps) if its night outside and goes to a dark theme but untill that moment you have to deal with the white map.
So there is an Google Maps widget, more like a shortcut called "Driving" and that one starts the Google Maps in driving mode and at night has the proper dark theme and the cool thing is that in daytime has the proper bright theme.
37. Is there a way to set the default start up volume?
Yes ! In Car Settings app, first tab, lower left, scroll down till you found "Default boot volume" and set it to a decent 7 or 8... the default is 18 and it's too much.
38. I am using a pair of sunglasses that are polarized when I am driving and when I look at the unit the screen reflections (glare) are rainbow like, extremely annoying and the screen looks somewhat darker? Is there a solution for that?
Yes I bought an anti-reflex screen protector, from here : http://www.magic-guard.com/screen-protector-antireflex.html
I measured the screen exactly and ordered 2 sets, one exactly what I measured and the second with 1mm smaller just to be on the safe side in case the first one does not fit for some reason. They take custom size measurements and they laser cut it to your specifications.
It cuts the rainbow effect of the reflections, the fingerprints are no longer a problem, yes it still gathers fingerprints but are not that visible. It cuts down a bit on clarity if you look at it really close, it's nothing bad, but that was to be expected since the screen protector has a grainy texture. I don't really notice any clarity issues because the unit it's at an arm length from my face at all times
39. The glare on these units with clear glass on a car environment are absolutely horrible, any solution?
Yes! look above at question 38. Indeed the fixed unit position, depending on the car of course, mine is pretty up on the dashboard and pointed a bit up so the light from the side windows reflects pretty badly. I cannot use it without an anti-reflex screen protector to cut down the glare.
40. I installed Poweramp, I have the Custom Keys mod installed and working alright with other apps but it does not work with Poweramp to start the music on engine start. Is there a solution?
Yes! In the launcher.sh I added this :
# Poweramp
poweramp="com.maxmpz.audioplayer/.PlayerUIActivity"
poweramp_press=$play
and at "97)" you have to replace the simple "$play" with "( $poweramp && sleep 2 && $play ) &" in the end it should look like this:
97) # ACC_ON - execute on key on
( $poweramp && sleep 2 && $play ) &
;;
41. I've made the modifications that you mentioned above at 40 but it take some time for the music to play when I start the engine.
Yes, indeed it takes about 15 seconds. I haven't found a solution for that yet. On PlayerPro music player I did not encounter these kind of problems, it was almost instant from the moment the car was on and the app resumed ( not exactly instant mode like 5-6 seconds overall). @dayanandgp mentioned that is the units fault because it insists to scan the USB ports at every unit wake up.
Later edit : I found out after tons of testing (of course it's never fast or easy) that when you have installed the Google app there is that 15 seconds delay at Poweramp start. Once I uninstalled Google app the Poweramp music starts playing 3-4 seconds after the unit wakes up. What's strange is that Deezer is not affected by the Google app presence.... with or without Google app installed it starts playing in 3-4 seconds after the unit wakes up.
42. Poweramp does not work with Viper4Android even if other installed apps seem to work file with Viper.
Go to Settings -> Audio -> Advanced Tweaks -> Direct Volume Control (untick / disable it)
Now it should work fine..
43. are you using a different Google account for the car or the same that you have on your phone.
For a long time I was using my main account but at one point decided to make a new one just for my car because these Chinese units have very poor security and if you value your privacy I recommend to do the same.
44. How do you decide on what model to buy from all the Chinese units?
1. First of all I look for the unit that has the biggest fan club here on XDA Without the xda support, the mods that xda members make these units are pretty poor even if they have good hardware because most of the time the software (out of the box) is so bad that it makes you regret buying it in the first place.
2. Second, EXTREMELY important for me is to make sure the unit has ROOT. Most of the units that I've encountered have poor EQ, (that translates into very poor bass output for my speakers), some have 3 EQ bands, some have 7 or 9 or 10... NO matter how many EQ bands they have I've never seen a good implementation of the EQ... That's why for me Viper4Android is a MUST have piece of software I can tune the sound to my preference and tailor it to my car speakers. Viper4Android needs root to be able to install and run. For me and my car speakers (nothing fancy, but of average quality (or a bit above average) Viper4Android trully made the sound quality good (took it from poor to good).
3. I start to read a lot on the people experiences, gather as much data as I can find and decide if the unit will suits my needs or not.
4. After I gather enough data I make a list of questions to make sure that the unit really fits my needs and that I got all the facts straight (sometimes things change for better or worse depending on the firmwares)
5. it's also a bonus if the unit can be purchased from an European store because in some countries with the import taxes and vat the price can get quite high...
45. Why have you chosen this unit and not a different one ?
1. Mainly for the instant on feature. Got tired of my old unit that took 40 seconds to turn on each time I got into my car. After waiting for 40 seconds had to wait a bit more to start the music app, pick up a playlist of album and press play... then start waze, select the location and set sail. Wasted time around 1-1.30 minutes each time. With the new unit the time the music starts automatically where it left off, the waze starts automatically, I only need to enter the adress and go... wasted time 20 seconds at best.
The moment I turn on my car the last used music app resumes playing where it left off (this works only the @gustden "no kill" mod). Basically in 5 seconds from the car start the music starts playing without me touching the unit. Pure gold !
2. BT tethering - second best feature for me because I stream a lot of music and it's not heavy on the phone battery while I am the road for hours,
3. because it has GLONASS... it helps a lot with the GPS precision in many situations
4. the screen is decent for such a cheap unit. It has decent brightness during daytime and also goes low enough during night time but not as low as I would have liked... I have to use an app to take it further down... wrote about about it.
5. the SOM has the BT/Wi-Fi chip on it so the android has full access to the BT and WI-FI module so I can enable BT tethering something that I haven't seen on other Chinese units.... it's also very important for me. The downside is that is badly implemented in the software out of the box.... of course. A mod made it work (as i said the XDA community is pure gold when it comes to these units) but out of the box the BT tethering is impossible.
6. has good BT and Wi-Fi signal quality... not amazing speed or anything but enough
7. it has 2Gb of ram and 32 gb (24Gb free in fact) storage and a decent CPU. The CPU is just decent, it gets the job done but I could not call it good. The storage is slow when it comes to writing and decent when it comes to reading so rebooting (or booting from shutdown) is a bit on the slow side compared to my old rk3066 dual core at 1.6ghz with 1 gb of ram and 8gb storage. My old unit, using the same apps was booting in 40-45 seconds and this new one (Joying Sofia) is booting in the same amount of time (more of less) but it's a quad with 2gb of ram... I expected a faster booting experience but it is what it is. The upside is that I rarely reboot it or forced to boot up from the shutdown mode.
8. It has hardware buttons and volume knobs - The capacities buttons are not good for car use, you need to take your eyes from the road to look for the buttons you need to press
9. It does not have an CD unit but I am not interested in having one. I haven't touched a CD in the last 3 years and I haven't bought one in the last 6. I stream all my music for convenience. I don't need to handle CD's while driving, searching for an album or song is lightning fast, compiling big playlists is easy.
10. The FM radio implementation software and hardware is decent enough on the Joying unit but rather poor in my opinion so I don't use it. I rather stream an FM radio station over the internet... I get a lot better sound quality.
46. I want to flash JUST the MCU from another firmware without flashing the whole firmware how can I do that
If you want for some reason to flash the MCU only extract these files from an firmware and put in the in the root of a flashcard or usb stick :
AllInOne.bat
SQLSOFIA
STM8_PROJECT cov.s19
STM8UD.BIN
EVEN if you flash the MCU only at the end of the flashing it will wipe the unit also so BE carefully.
47. What If I want to flash the OS part of the firmware but I want to keep my old MCU
If you want for some reason to flash/reflash an firmware without the MCU (because you want to keep the MCU you have) unpack the firmware archive in a folder and delete these 3 files (just the 3, SQLSOFIA is needed for the unit to detect and flash the firmware, it's the flash trigger file)
AllInOne.bat
STM8_PROJECT cov.s19
STM8UD.BIN
48. I can't adjust brightness properly, it's way to bright at night and the "Backlight current adjustment" menu from the Car Settings app is gone
I flashed the 25May firmware the FYT5009 version on a 5009 unit and discovered that It does not have the brightness menu in the Car Settings app so I flashed the 25May FYT6021 version on the 5009 unit, flashed ok and the brightness menu showed up.
Then decided to compare the files (binary) between the firmwares to see what files are different and except the customercfg.txt and rksofiacfg.cfg all the other files are identical between the 2 firmwares.
The rksofiacfg.cfg file has the same size on both firmwares but the content is different.
It ALL comes down to this file when it comes to "Backlight current adjustment" menu being present or not : rksofiacfg.cfg
My advice is to get this file from a previous firmware that you used and where the "Backlight current adjustment" menu was present and working.
49. Is just me or the BT speed is lower with the Android 6 firmwares versus the Android 5 ones?
Indeed for some reason with Android 6 the bluetooth speed droped like 50-60%. Also I find the unit pretty picky with the phones when it comes to Bluetooth speed, I tested with an Huawei and it would never get past 220k DL but with a Samsung gets to 340k...
50. Is there any piece of software for the Joying unit that can make my life easier?
Yes it is. Thank @surfer63 for his nice piece of software!
More info here : https://forum.xda-developers.com/an...s/joying-extra-tools-apk-apk-to-help-t3628200
51. Can I cut the 3 second lag on the launcher.sh somehow? I feel that when I use the custom keys mod there is lag when I use the keys or steering wheel buttons.
@surfer63 gave some pointers here : https://forum.xda-developers.com/showpost.php?p=73023988&postcount=930
Edit the launcher.sh with Notepad++ and add "#!/system/bin/sh" at the beginning of the file
"This makes it slighly faster (approx 1 second) as the system does not have to check first whether "this executable" really is a shell script.
Next to that I removed all unused stuff as it makes the loading of the script slightly faster as well, but that should be in the range of milliseconds and is actually not worth the effort."
52. I want to turn off the screen but not the unit, the brightness bothers me at night.
Press and hold the MUTE button for 2-3 seconds and the screen will go off. Push any button or touch the screen to turn the screen back on.
53a. What cooling solutions do you have for the 5009 and 6021 units given the SoM have different heatsinks (more like heatplates)
Disclaimer : I am just giving some ideas here... just to make sure that your modding is safe talk to someone with extensive experience when it comes to electronics
IF you want to KEEP your warranty, especially when you have 2 years (European buyers) the best and single solution is to mount an 80 or 120 mm fan on the top of the case.
The fan needs to be high quality, silent, low power, low speed, no more then 1200-1800 RPM. Use a FUSE box for the FAN... ask someone with experience in electronics for more details.
You will need to cut a hole for the fan or drill a lot of small holes in the top steel cover for the air to get in... If you cut a single big hole and you are worried about the dust use an magnetic dust filter on top of the unit... you can find plenty of models online for PC cases.
With just a fan (and no additional heatsink glued onto the SoM), depending on your unit placement,the dash configuration, fan speed you might never see impressive low temperatures but at least you will not see the unit getting toasty at 100C. To explain a bit more about the temperature in the dash... some car have the air vents above the headunit and those vents cool the place up when AC is running , some cars have the headunit totally isolated... just a hole in the dash with little to no air getting to the unit so in this scenario the unit will heat up slowly but surely no matter what (in this case an the fan's help will be limited but still better then nothing)
On the 5009 - given the smooth surface, first remove the stickers, clean the surface, then find an aluminium heatsink that has many high fins (help dissipate the heat faster) and it's tall and long enough to NOT cover the SoM holes, use some thermal adhesive and glue it in. Also try not to pick up heatsinks with thick base, it ads up more weight but aren't necessarily more efficient. The CPU is under the "dent" so the dent and the area around it is very important. I guess you could fill up the dent with thermal glue to help with the contact of the new to be mounted heatsink although I did NOT test that.
You could glue in 2 heatsinks if they are the right size and the SoM holes will not be covered.
Example of heatsinks.
1 : https://www.micforg.co.jp/images/c_cs.jpg or this one http://northamericanshores.com/slowblog/good_heatsink.jpg
On the 6021 - given those tiny fins using a thermal adhesive on it it's a bit tricky. The CPU is under that middle flat square spot. You should use enough glue to fill the space between the fins (around the flat spot) to maximize the contact surface between your (new) soon to be mounted heatsink and the SoM heatsink. Be careful that a bigger amount of thermal adhesive will have a longer curing time (also is more liquid).
Use adhesive tape to cover the holes of the SoM heatsink so you don't accidentally get thermal adhesive inside those... and carefully remove the adhesive tape later when thermal adhesive has hardened enough.
About the height :
1. If you have a single DIN unit the heatsink needs to be lower so maybe 2 cm tall.... you need to measure because it depends on the fan position
2. if you have a standard 2DIN unit 3-4 cm would work ok (even 5 cm might be ok but check if you have enough spare room for the fan above)
When it comes to heatsinks the bigger the better... the more surface there is to dissipate the heat the cooler the component will get. I prefer aluminium heatsinks over the copper ones (when we talk about gluing them to the SoM) mostly because of the weight but there are some other issues like corrosion (copper with aluminium).... given the 5009 SoM is soldered to the motherboard the weight of the SoM+heatsink, combined with the car vibrations (more or less, depending on the car brand, engine type, road quality) could stress too much the SoM soldering points and possibly crack/break some in time. I am NOT sure of it, I don't have the means to test that, but just by looking at the soldering points I just don't have enough confidence to recommend an big 200-300 grams heatsinks. The heatsinks I've installed were around 60-120 grams max.
On the 6021 unit giving the socketed type of the SoM (way more solid built than 5009) you could probably install an heavier heatsink, say 200 grams, without worrying so much.... again, I have not test it to be absolute sure that nothing goes wrong in 3-6 years time.
Do NOT cover the SoM ventilation holes. Again, I don't have the expertise to be able to tell what happens if you cover those but I think the holes are there for a reason so let's keep them open.
Use some adhesive tape to cover the holes and remove it after you finished the modding (to prevent the holes to fill up with glue)
These thermal adhesive are good :
Warning : Both linked below are PERMANENT thermal adhesive, once you glued the heatsink on the SoM ... it's there for LIFE
I used this one because it's completly safe, it's not capacitive or conductive.
http://www.arcticsilver.com/arctic_alumina_thermal_adhesive.htm
This is better formula for heat transfering but it is slightly capacitive :
http://www.arcticsilver.com/arctic_silver_thermal_adhesive.htm
Be careful not to drop some by accident on the motherboard.
These 2 adhesives curing time depends a lot on the temperature.... the higher the temperature the faster the curing time is
Fans that I would use:
These 2 are adequate for a 2DIN unit :
Noctua, 80mm, 1200RPM - http://noctua.at/en/products/product-line-redux/nf-r8-redux-1200
Noctua, 120mm, 1200RPM - http://noctua.at/en/products/product-line-redux/nf-s12b-redux-1200
And maybe this ones are good option for some that think that they need more airflow although it will generate a bit more noise:
Noctua, 92mm, 1600RPM - http://noctua.at/en/products/product-line-redux/nf-b9-redux-1600
Noctua, 80mm, 1800RPM - http://noctua.at/en/products/product-line-redux/nf-r8-redux-1800
One thing I don't know is how these fans will behave in very cold weather, in the winter time at -10 to -25C.
I opted for the fans above because the Noctua brand is well known for it's very high quality fans and designs, 6 years warranty, having low RPM is good because they are very quiet although the airflow takes a hit, but I am using the 80mm 1200RPM fan and it's more then enough when you have an heatsink glued onto the SoM.
Remember that in the end no matter what fan size or speed you end up using, it is better to have a fan because every bit of airflow helps so if you don't have the space (in 1 din units) to install an 80mm fan install something that fits your space. Don't forget to install a fuse on the fan... if for some reason the fan breaks and for some reason shorts out... you need a failsafe (fuse).
go to 53b ->

53b. What cooling solutions do you have for the 5009 and 6021 units given the SoM have different heatsinks (more like heatplates)
-> continued
Just some test thoughts : If you want to do some testing with various types of heatsinks because you don't know what to install, cover the motherboard with adhesive tape and leave only the SoM heatsink heatplate clear (to avoid a short in case an heatsink falls down the SoM heatsink over the motherboard. Now cover the SoM holes (to avoid thermal paste gettin in there). Take some thermal paste (NOT thermal adesive) and spread a thin layer on the whole SoM heatsink/heatplate and put the heatsink/heatsinks on it and mount the fan above it. Be carefully with the fan speed because the thermal paste does not offer a lot of stability for the heatsink... so a big fan speed might push the heatsink away from the SoM heatplate. Test for temperatures. Use this app to check for temps https://play.google.com/store/apps/details?id=info.kfsoft.android.MemoryIndicator it shows the CPU temp (1 core of your choosing) and CPU load (average or per core) at all times in the upper bar (if you configure it)
Use this app to simulate heavy system load to check how is the heatsink coping with the heat : https://play.google.com/store/apps/details?id=com.into.stability
Decide what do you want to keep. Clean very well the thermal paste from all the heatsinks and SoM heatsink with this http://www.arcticsilver.com/arcticlean.htm
Use permanent thermal adhesive this time to glue in the heatsink of your choice. Take all the adhesive tape out.
In the end is all about testing and taking risks, you don't feel like installing a big heatsink, you can do with small (15x15x15mm) heatsinks as long as you install many, not a single one but also remember that once you decided and you have glued them in and you are not happy with the performance (the risk i was talking about) there is no turning back.... if you don't feel like installing an 120mm fan because you feel like installing an 140mm fan that is laying around for years... install that one if it fits... if it breaks down after a week (risk) take everything out and change it.....just test everything before mounting it in your car and ask people if you want to do electric/electronic modification that you are not sure of.
Also when you drill holes always clean the holes of the metallic debris carefully, because if the debris drops on your motherboard it could short it out.
Later edit : Some people asked me if this mod it's a must and if their unit will fail if they will not mod it. If you ask me it's a must and without the mod the unit will fail and let me explain you why because it depends on a lot of factors. You see the CPU was made to function from -25C to 85C, 85 being the max safe temperature. The CPU on this unit gets easily to 90-100C if you run the unit for 1-2 hours, during a hot summer day, running an music player and a GPS software like Waze for instance (that tends to use a lot of CPU power). If you drive constantly for hours every day, during the day and you live in a hot climate this will shorten the lifespan of the unit by a lot. Not only that the CPU works above it's specifications but all the chips around the CPU (the RAM, storage chips, GPS chip, Wi-Fi, BT) will be force to run very hot because so called heatsink (more like a heatplate) will radiate the heat and slowly cook up everything on the SoM....sooner or later one of the chips will fail.
So if you are the kind of guy that drives 30 minutes in the morning and 30 minutes in the evening while listening to the radio or to some mp3 music, you keep your car always in a garage and you do not live in a hot climate, your unit will have a long life. But if you live in a hot climate and you drive a lot during the day, with music streaming over the internet, GPS software always on, you only park outside in the hot sun that gets the interior of the car frequently to 40-50C.... well, your unit will have a very short life.
54. What apps do you use to monitor the CPU temp?
Right now I am using this one, Resource Monitor Pro, because It shows me the temp (on a core of my choosing) but also the CPU usage (average) the free mem and CPU speed) and you can place all these info in the upper bar, visible at all times.
a. Paid version : https://play.google.com/store/apps/details?id=info.kfsoft.android.MemoryIndicatorPro
b. Free version : https://play.google.com/store/apps/details?id=info.kfsoft.android.MemoryIndicator
I also used this one, CPU Temperature Pure, it's a little more basic, it displays the CPU temp only but you can place it on the status bar, always visible and it looks good.
a. paid version : https://play.google.com/store/apps/details?id=com.yanyan.cputemppure
b. free version : https://play.google.com/store/apps/details?id=com.yanyan.cputemp
I also used this one to be able to look at all the CPU cores temps at once :
a. HWMonitor Pro - https://play.google.com/store/apps/details?id=com.cpuid.hwmonitorpro
b. CPU-Z - https://play.google.com/store/apps/details?id=com.cpuid.cpu_z
55. My steering wheel NEXT and PREV buttons functions are reversed. What can I do?
My previous unit an Witson 3066/1Gb ram had an CAN decoder that worked fine for my Ford but the Joying ones work only 85% fine meaning the PREV and NEXT buttons were reversed and that was a pain to use since all my life when I push the NEXT button I expect to hear the next song not the previous one. Although I was struggling to correct the Joying CAN mistake I could not because I did not find any way that I could reflash the CAN box. Joying said that the CAN might not be 100% compatible with my car although it should be.
Even if the old CAN box from my former Witson unit was looking exactly the same and the wire socket was exactly the same as the Joying one, the wiring was completely different, different wiring positioning in the socket, different wire colours. The internals of the CAN boxes looked almost the same but I did not had the courage to test the Witson one on the Joying afraid that I would damage the headunit or more importantly the car...
What I did in the end was to directly connect the resistive buttons of the steering wheel directly to the unit using some of the printed diagrams found in the unit box (bypassing the CAN) and program them via the unit software and let the CAN box to decode the other stuff like putting the car in reverse, turning on the lights, feeding +12V to the unit when I start the car.
What I learned is that CAN box is a black box... if it's not working it's almost impossible to find a fix of any kind... or buy a working replacement...
56. Do you recommend the 1 September Android 6 update?
Short answer, no! Long answer read here : https://forum.xda-developers.com/showpost.php?p=74324433&postcount=338
57. I just got my unit, it has Android 6, what build/release date shall I use in order to have a functional Viper4Android ?
I just tested a bunch of Android 6 firmwares over the last 5 days and these are my results : https://forum.xda-developers.com/showpost.php?p=75117890&postcount=412
Unfortunately none is as good as the Android 5 latest firmware ... not even close.
58. My GPS signal is poor. Any ideas?
Things to do :
1. check if GPS cable it's securely attached to the headunit
2. check the GPS antenna positioning and the signal strength - I personally attached directly to the windshield for the maximum signal strength but It's true that it does not look that good
- if the positioning is bad (under the dash for instance) and the signal is weak when you are on the road, open skys all around you, then it will be worse in the city and you might even loose it if you have tall buildings around... if that's the care you really need to reposition the GPS antenna
3. some windshields have a special coating to reduce cabin heat (have a greenish/violet tent when you look from outside) that blocks GPS signals up to 60% in that case you need to find a solution to mount the GPS antenna on the outside of the car OR in same cases there are special areas on the windshield (usually near/around the inside mirror) where are safe to mount the antenna - if that's the case check the car manual for more details of those zones
4. some windshields have heating elements in them, very thin and tiny wiring that heat up the windshields.... those block the GPS signal up to 40% but there are areas where you can mount the GPS antenna on the windshield without issues
5. antenna cable might get broken (inside wiring breaks and usually it's not visible when you visually inspect the cable) if the cable is bent, tensioned or from vibrations (usually on diesel cars where the engine vibrates a lot) - if that's the case buy another from a store that accept returns, it costs 9-12$, install it, if everything works fine then keep it... if not return it and go at step 6
6. open up the HU case and check GPS antenna cable soldering on the SoM, check if the soldering points are ok
7. if you use a custom rom with Xposed check if the GPSSpeedFix module is install and active, disable the GPS module from Xposed and restart the HU, check the behaviour again
8. if nothing works I would suggest reflashing a stock Joying firmware, so far, at this point in time (17/feb/2018) the December firmware worked the best for me... I still haven't tested the January one. Please follow the tutorial I made for flashing/reflashing.
59. My unit looses the GPS signal. Any ideas?
Check the answer for the question no 58 (above)
60. Where can I find/download the stock Joying firmware?
Have a look here : https://www.joyingauto.com/blog/tag/joying-intel-sofia-android-car-stereo-software-update/
Download the firmware based on your unit MCU (you will find it in the settings-> about section) and screen resolution.

agreed excellent, i just gifted him a month of ad-free XDA

Many, many thanks @CadillacMike for the gift and many thanks @sanangel.
For more then a month I've read everything there is about the units, flashed my HU at least 30 times to test for everything so I figured it's time to post most of all I know about the unit.
@gustden inspired me with it's roll-up thread on android 5... Being a newcomer, with zero knowledge about this unit his thread was pure gold for me back then.
It's work in progress, I have more to write but I figured that I need to post this wall of text so people can use it untill I prepare the rest.
Right now I hit a bump, I can't edit the post anymore... something about a security token error... I wrote to an admin to help me out... I still need to clean the first one a bit.

Solution 1
1. Enter the Car Settings app
2. Select the lowest tab on the lower right (the one with the screwdriver)
3. Enter code 3368
4. Scroll towards the bottom and you shall see a option named :”Backlight current adjustment”. I have this menu, some said they don’t have it so my guess is that it depends on the model of the unit … can’t say for sure.

I am really sorry that it does not show. For me it did not show in the 12May firmware and it took me weeks of emailing every single day trying to to explain in various ways how important is this menu.
In the end they understood what I was talking about and I can see the menu in the 25May update. In fact I was convinced that everyone could see it. The language barrier is a really big issue so you need to have patience. My advice is to show them screenshots of the missing menu (there are some posted by me) and ask them to bring the menu back in the next firmware for your unit. And don't give up until they understand what you want from them. Compared to other Chinese HU brands that I've talked to, the support from Joying is actually quite decent.

Really appreciate the write up! Does anyone have the issue when recieving a phone call while running Google Maps and the half screen bluetooth dialer comes up and all the caller can hear is a horrible distortion static sound? I can hear the caller but all they can hear is this terrible noise? I closed Google Maps and when the full screen bluetooth dialer comes up the call is fine.

That sounds like mic/cable interference to me. It a hardware problem. If you are using the external mic, from my testing (unit tested on my desk at home) the mic cable is not shielded at all and picks up really easy all the interference that the unit gives out and the one you are talking to on the phone hears all these strange sounds that the mic cable pics up.
1. first test mic cable is ok, test that is plugged in correctly, make a Google + voice call again, if the sound is bad go to step 2
2. unplug the mic, the one near the screen will take over, do the test again ? is it better? I bet it's better
3. if it's better you need an mic with good shielded cable
4. if the call test it's not better and the sound is same bad quality that means that you have an hardware issue related to the internals, mic, flat cables.
5. you can either have a look in side and check if all the flat cables inside the headunit and properly inserted
6. or you can send the unit for warranty repairs

Thanks that all sounds like good steps if the Mic was always like that. However it worked fine prior to Android 6 update. And still works fine, it only causes interference when the bluetooth dialer overlaps with Google Maps.

I am curious if with the internal mic you encounter the same problem...
Have you wiped the unit after the update?
You updated from what version to what version?

Is there any way to disable the external mic without just unplugging it? As it is currently installed in my truck and would be tedious to remove.
Yes I wiped the unit after the May 25 update, but did not wipe it prior to the update. Possibly the issue?
I went from May 12 to May 25 update recently, but I'm not sure when the interference started. I know 100% it worked on the last newest 5.1 update.

Can someone confirm that the radio skins are working?
Dooing all those steps and i can see in cmd that it should work but when i reboot i still have the original radio app.
Thank you and greetings

Eureka!! I figured it out. I ended up factory resetting, reflashing, and then resetting again. However the problem of terrible noise with Bluetooth Calls during Google Maps still persisted. I was quite disheartened, I also noticed if I hit the home button during the call the call quality would return to normal. So I knew it was something to do with Google Maps. My last ditch effort was to go into the Google app and disable "Ok Google Detection in Google Maps" and VOILA I tested a call during the same scenario and no weird interference! So if anyone else has this issue, just do as stated. Finally, I think my head unit is near back to where I want it.
Cheers Thanks again for all the Q/As it helped greatly!

Thank you for returning with a solution to your problem.
Tried to recreate your issue on my unit but I could't. (paired phone, google maps, google app installed, calling my phone while google apps running)
Do you have Google Assistant (velvet.apk) installed by any chance?

No I dont have Google Assistant (velvet.apk) installed. Just have the latest v6.3 nokill w/ gvs installed. My unit is JY-UL135N2.
Just noticed my bluetooth connection sometimes drops after ahwile on my phone, and I have to reconnect. Almost thought I was all fixed, damn.

That is a weird issue. Are you sure it started after you installed Viper? What unit and android version do you have?
I've installed Viper on 2 unit models, Joying with the 5009 SOM and with the 6021 SOM. Both units has volume wheel not the crappy touch volume bar. I've never had any issues.

Viper4Android working perfect on my device.

You can buy the unlocked version from Google and use it on Verizon.

>Do I want a Pixel?
Depends on if you do or not.
Jokes aside, you can unlock a Verizon P2 if it hasn't taken the Jan update yet. Visit in store and ask to see a P2 in box, no SIM or wifi please. The box will indicate the factory software. Once you find a winner (hurry, they're fading from inventory) just carefully apply the unlock steps and enjoy.

Go Ahead
Yes, you should, Pixel mobiles are the best mobiles according to my friend's opinion, I'm also going to buy it next week but first I have to write my assignment.

So, I now own a new Pixel 2 Google Edition.
1st Pros:
Luv that its already stripped down and lean in the stock OS. @8.1.0 ver.
1st Cons:
Device does not report battery lvl correctly in notifications tab, always states 100%, icon always shows full.
WiFi icon appears to show only on, no signal strength at all.
Totally dislike notifications tab period! Too much redundancy! To much access points to the same stuff.
Decided that it should be a central home screen. A group of 5, home at center. Now that leaves 4 sides or edges.
1 edge for calling and texting, swipe left edge
1 edge for social media outlet of choice, swipe edge right
1 edge for camera and video, swipe edge down
1 edge for video and music playback, swipe edge up
Or could be other choices instead. Point being all the different access methods, repeat the same things so lets get simple.......................
Its about personalized customization of actual use. right now we just customize the presentation of gui's, color, form. There is nothing intuitive about OS use tho!. Things like smart bullitain are really useless and forced on us, seriously, wonder around with a live feed always going.......no.

Interesting: on 8.0 the Pixel 2 battery meter stuck at 100% charge for a long time (not permanently), but that was fixed by updates. Should not be a problem with 8.1.
And the WiFi icon works just as expected, i.e. shows signal strength (though no "activity arrows" if you were used to those). So this sounds like something is wrong.
I'm not sure what you are saying about the notifications. Can you give some examples?

I don't have anything forced on me - I just turned off (or didn't turn on) anything that didn't interest me (with Google's launcher being one of the first things to go). There are always alternatives.

So I have discovered that enabling the ui demo mode was the problem with the status bar and battery level reporting, enabling this bad.
I have learned of and enabled the system ui tuner. This ended all the phone functions, status reporting, very sweet. Now the status bar just reflects certain running services.
I also installed the Android P theme launcher, I like it. Has a sidebar option, the ability to hide the status bar, the ability to alter dock settings. So I essentially dumped some cpu reporting cycles, so to speak, let see how bat life responds.
Without root, I have gotten closer to what I want. Need to get TWRP installed and a nandroid made.

Ehm, AOD is just a additional option that is included so you can check the clock and whatnot without the need of turning on your screen.
The touch response in the screen is controlled at the kernel driver level and is only affected (in a negative way) by yourself and your fingers and how dirty the screen is.

I might be the only one but I disabled aod with no ill effect that I am aware of. I don't care for it.
Also, enabling the up-down arrows on wifi-data is a simple mod.

aod affects pick up wake, double tap wake. touch responsesivness is very finicky as is, worse with aod off.

You are just experiencing some placebo side effects, mate. AOD have NOTHING to do with the screen sensitivity.
The screen- and touch response is controlled at the kernel driver level. Not at software/application(s) level.

AOD
My issue was this, if I left the phone idle and untouched for awhile and then came to it and double tapped the screen, it would not wake up. I would have to use the side button to open. Sometimes the action of lifting would allow the double tap to work, but inconsistant. Doing the squeeze for the assistant was inconsistant as well.
The touch screen acts inconsistantly. If you do a horizontal movement, it interferes with a vertical swipe, I mean things seem to get canceled out. I have to initiate action multiple times to win.
heres the deal, i do not give a flying bleep whether its a hardware or software issue, I would like smart answers that give a solution, not assign a blame or fault. Or tell me I am somehow misinterpreting what I percieved.
So here is my take. The dam phone is overloaded with redundant crap, that steps on each other, interfering with it self. IMO everything in this phone should be disabled at purchase. The consumer should then enable those things it wants! Possibly eliminating over extended, overlapping services and hardware.
Now I say this because it appears that in fact to much was being asked of the phone and it was flipping out basically.
I dumped some google software, pretty much what it would let me.
I disabled the screen saver function, my belief is this was why i would not wake up. Screen saver or no, it times out going to the aod clock display, which I like. Now the phone responds to a lift and double tap everytime......................................................................................
I was using a single home screen, with the android p launcher sidebar. My issue was using swipes to navigate web sites, read stuff, sift thru pages. The swipes were not responding properly, PITA. It seems that by using a single home screen, it stilts the screen edge, makes a dead zone, interferes. Not to mention the right side slider swipe icon is useless as presented. It seems that enabling a 2nd home screen helps with that dead zone. Its not 100% when swiping thru pages but response has gotten more tolerable.
IMO
Thanks to fakebook, everyone should understand what these devices are truly about, DATA MINING.
Google
Verizon
LG,HTC,Samsung,Hauweii
Each and every phone has at minimum, 3 different forms of active data harvesting going on. manufacturers, carriers, media apps. The greatest performance killer of all, not to mention...........................................I have come to despise predictive search algos, targeted marketing adds, basically digital junk mail inundation.

So,
Been using the pix 2 awhile now. Really hated Oreo so I went into beta play to get pistachio. Used ver 3, now 4.
I really liked the initial ver 3 update cuz it removed so much bloat from carrier crap. Less google crap too it seems.
Now I like the responsiveness much better with ver 4. I still have everything I can disabled, disabled or removed. No AOD, active edges, tap to life, no music, movies, tv. No auto pay, auto track, auto search, google talk, nada.
Its a com device, an internet search device, thats it! Bat life is good, real good.
These devices are overburdened with non-sensical, redundancies, that create huge performance impacts. Seriously, how many ways are there to access a smartphone, on all at once.
Now I lift the phone, touch the physical button and walla, works every dam time.

Yep, flexible to meet millions of users needs...

It might also give anyone also in a similar situation additional information to help deciding.

Can I Stop a Samsung A51 turning off. The 10 mins allowed is not long enough,

I want to use my A51 as a Sat Nav/cycle route guide but Samsung have limited the on time to 10 minutes if it is not used, and when Plotaroute (this is the navigational aid) is operating the phone does not see this as being "in use" and so shuts down. This seems bizarre to me especially as the battery life seems very good. Is there any way round this. Samsung say the 10 minutes can not be increased.

Are you saying the screen won't stay on? You can get an app called Caffeine. It keeps your screen on only when you press the QS toggle, and you can have it turn off automatically when you manually turn the screen off using the button.
If that's not the case, try seeing if the app "plotaroute" has the permissions it needs.

Thanks for your help. Caffeine seems to be exactly what I need. I do find the instructions a little difficult to follow and I would like to connect it to auto run with Plotaroute and I an worried about doing this myself but fortunately have a very competent programmer relative who will set it up for me. Ploaroute does not have the ability affect the phone screen time out. Incidentally certainly for biking, although it works for foot, car etc, after doing some research I have found Plotaroute to be the best and cheapest of the ones available.
Again thanks for your help
