I am wanting to purchase one of these Pioneer units, but they havent tested many wm6 phones, or HTC for that matter.
Has anybody got one of these headunits, or any other pioneer bluetooth headunit and use a WM6 HTC Phone (kaiser preferably) with it?
What issues am i likely to have? Surely bluetooth is bluetooth for making and receiving calls.?
Thanks Guys.
Hello,
Here is a copy/paste of some messages that i have sent to another person that have solved his problems. If it didn't work, please advice and i will try to help you more but i don't use any more this Pioneer P70BT radio player:
" On Asus BT manager, choose Pioneer (click on it and hold on it , NOT just click) then it will show you a menu , on that menu choose "Set as hands free" or "set as default hands free".
After that, DOUBLE click on Pioneer icon (don't forget that your Pioneer should be set as connection open), then for the first time Asus will ask for "pin number" , then you enter 1111 and also you should tick the mark that say "set as authorized device" ,because if not, allways will ask you for pin code. "
" Did you read your Pioneer manual???
-Page 41 at english manual (section 08 / points 1 , 2 , 3 etc)
-Page 42 "Registering your cellular phone featuring bluetooth.... when it saids "use multi-control" it means that use the joystick turning around OR up/downd/left/right
After doing what is writen on page 42 (even there you can delete "read page 43" your paired phone as many times as you want) you should be able to pair it again at any of the 5 phone positions plus 1 more for Guest (if you fail to do it read the point 4 at page 42 again).
Please try this way first and don't forget to set your Asus BT accessibility as "allow other devices to connect" " all devices"
AND THE MOST IMPORTANT GO TO Start/Settings/Connections/Beam and tick "Receive all incoming beams "
" Did you allready tryied this:
-Don't use the radio's 'register' function. Go to connect and set it going then go to the pda and add a new BT device with the code 1111.
What you have to do:
- First enter the phone menu on Pioneer.
- Then choose a place where you want to register your phone (ex.: phone1, phone 2 etc.)
- Press center on pioneer and select CONNECTION OPEN on Pioneer.
- Then search for the Pioneer on Asus, then choose the Pioneer and enter 1111 for the code.
- After that, pioneer should write Phone registered. (Sometimes it will not work for the first time).
- Than you can connect your Asus to the Pioneer. "
" Try this :
1- At BT Manager Click and Hold on Pioneer icon and on the pop up menu choose "delete"
2- Then at botton rigth soft key "menu" (click on it) choose "paired devices" . On the screen that you see now ADD REMOVE ,choose Pioneer and click on REMOVE.
3- Now on that screen click on ADD , click on SEARCH (is the litle icon on the rigth of "Device" )
then CHOOSE Pioneer . Enter 1111 and click "OK" at the very rigth top corner.
(Don't forget that Pioneer should be set at connection open)
4- It will give you the message "Pairing ok"
5- Then go back to BT Manager and CHOOSE at the botton left soft key "new" , then on the screen that appears click on hands-free/Headset setup (just click on it to get it on blue color selected)
Then at the botton right soft key choose NEXT.
Click on Pioneer icon that you will see
Enter pin again and it should be connected. "
i will test this out and get back to you, thank you very much
just so you all know for future reference, my dutty wm6.1 kaiser connected fine, downloaded the entire phone book within a couple of seconds, no issues what so ever.
Very Happy

I'm glad you work it out
Only a year late but the HTC hero pairs fine with Pioneer fh-p80bt
..try it in the store
when I buy a stereo, I take my phone into a store with a demo unit...pair it, play some music(loud and thumpy just to wake up the store and check out the phone book,.
Then I know for sure about the particular model. Even if you buy on the internet, I can usually find a store with a demo of the unit ....
Hello there,
I've bought a second hand car with the chinese A-Media android system in it. Could it be the system is storing data about my driving routes? No matter how many times I try to disable the location function, it keeps turning on everytime I restart the system or better to say the car. Have also tried to disable as much apps that weren't necesarry for me, but some seem to be not deleteable (e.g. something like a GPS coordinates app? ). The previous owner was a company that used the car for their business.
How can I solve this, and is my feeling of being tracked / data being stored in the device/car real? Thanks!
Of course it's tracking you it's an Android system. If you have any concerns about the previous owner you should do a factory reset but since it probably came with some "special apps" you should look for the original firmware or root it and extract the apps. If you can turn off the GPS in settings just turn it on when you need to use it.

thanks for your info. It just bothers me that Location automaticly turns on when I start the car. Who says me some app is not spying on my location ? Turning it off in Settings does not work. Turns on automaticly every time at startup.
If you can't turn off the GPS from the Android settings you might be able to do it in the factory menu. Don't forget GPS and location are 2 different things. Do you know which HU you have?

I didn't knew it were 2 different things. What do you mean by HU ?
When I try to enter factory settings it ask for a password which I dont have.
Some info:
Model numer : A-MEDIA AUTO ( 1024 x 600 W )
Android version 6.0.1
Kernel Version 3.10.0 [email protected] # 1019
Buildnr px5-userdebug 6.0.1 MXC89L user.hct.20170619.104614 test key
MTCU version MTCD_KGL_V2.54_5
jun 15 2017
CPU 8 core 64bit CPU coretex-a53 @1.5G
mem 2000mb
You should be able to find lots of help for that unit. Sorry HU is head unit. Try 1260 for the password or maybe 8888. Refer to it as MTCD KGL and more people will know what unit you're talking about. Try not to change too much stuff in the factory setting it can make the HU stop working.

The models are manufactured/assembled by Joying, but the motherboard/MCU is made by FYT who also "make" the Android and system apps for the units. There are a number of FYT compatible units available, like Joying, Sinosmart, Zhan, Funrover, Flyaudio, Witson, T'eyes and multiple "unnamed/unbranded" units. Not all of the units of these companies are FYT units though.
This thread is not for discussing your issues in case "things" don't function or questions like "How can I ../ How do I ../Where can I find ../ etcetera. There are other threads for that. If you have good tips yourself, please add them.
Almost all Q&As and tips are collected from other or much older posts. Too many people to mention. Thanks all!
I hope this will remain a "work in progress"!
#1. Passwords:
Factory menu / Developer options: 3368
Backlight Current Adjustment: 5768
Door lock interference: 0000
To change home launcher: 8086
#2. Where can I find the latest (and/or older) firmwares for my Joying unit.
You will find them on the Joying website www.joyingauto.com inside the blog: Updated firmware.
#3. Should I always upgrade to the latest firmware?
Theoretically: YES. Bugs are fixed. New features are added. But..: sometimes new bugs are introduced.
#4. Are there other Howto's, Q&As, Tips available?
The Joying blog at https://www.joyingauto.com/blog/
The Youtube Joying Boyka channel.
The official Joying forum: https://forum-joyingauto.com/
Modding your Joying/FYT SC9853i unit without root: https://forum.xda-developers.com/an...modding-joying-fyt-sc9853i-unit-root-t3974357
#5. Will all my apps and data still be there when I flash my unit with a new firmware?
That depends on the contents of the file "updatecfg.txt" in the firmware. See the explanation in post #1 of Modding your Joying/FYT SC9853i unit without root
#6. Can I root my unit?
Yes, you can. See HowTo: Root Joying SC9853i Head Unit.
#7. I have my unit rooted. How can I (relatively) easy install mods or tweak my unit?
Use the "Joying_Extra_Tools" app (also JET apk) which allows you to install Radio, Bluetooth, main server (nokill) mods and tweak/optimize (immersive mode, overscan, DPI, etc.) your unit.
#8. All the apps are killed when the unit goes to deep-sleep. Can I change this?
The unit does indeed kill all apps upon going into "deep sleep", apart from a few system apps.
Solution 1
(No root required) By modifying the "skipkillapp.prop" as described in both post #1 and post #2 of Modding your Joying/FYT SC9853i unit without root, you can change this.
Solution 2
(No root required) Install a nokill mod using a prebuild flashable image from post #3 of the thread "Modding your Joying/FYT SC9853i unit without root". This mod deactivates the "kill_all_app" function in the main server app.
Solution 3
(root required) Install a nokill mod (using the JET apk). This mod deactivates the "kill_all_app" function in the main server app.
"Solution" 4
(No root required for "starting apps" activity) If you simply want "your" app available after deep sleep, a much "cleaner" way to do this is to use @bambapins FYTStarter apk that lets you autostart apps on "waking up" of the unit. See post #1149 of the "Joying Android 8.1 Intel Airmont eight-core 1.8GHz SC9853i (4GB RAM, 32GB flash)" thread.
Alternative: You can assign any app to the "Navi app" setting inside the Joying settings. You can use Tasker/Easer/Llama/MacroDroid/Condi/Etcetera to start apps/do actions, etcetera after wake-up. Note that for some of these actions you need root access.
#9. I do not really care that apps are closed on going into deep sleep, but can I start some apps on waking up after deep sleep?
Like above topic: (No root required for "starting apps" activity) If you simply want "your" app available after deep sleep, a much "cleaner" way to do this is to use @bambapins FYTStarter apk that lets you autostart apps on "waking up" of the unit. See post #1149 of the "Joying Android 8.1 Intel Airmont eight-core 1.8GHz SC9853i (4GB RAM, 32GB flash)" thread.
If you are rooted you can use FYTStarter to start the accessibility service. It is not necessary for root to be kept active: it is enough to install and launch FYTStarter only once, while you have root. Later, even if you remove root, the app will still be able to start the accessibility services.
#10. Can I make modifications to the apps on my unit without root?
On these SC9853i units, you partially can. See this Modding your Joying/FYT SC9853i unit without root
#11. Are there Custom ROMs for this unit?
No, currently not. It is unlikely they will be created, but you never know.
#12. The unit starts some default apps on certain hardware keys or "system actions". Can I change this (without root)?
Yes, you can for a number apps and a number of SRC/MOD Steering Wheel keys. see the "FYT HW OneKey app". It doesn't need root, but will also work with root.
#13. I did something stupid and now my unit is in a boot loop or does not get past the boot logo. Help!
See post #4 in the "Modding your Joying/FYT SC9853i unit without root" thread.
#14. The Bluetooth app can only pair a few number of devices. Can I change this?
Yes, but your device needs to be rooted. @seb21 has modified the Bluetooth app (based on 17 Sept 2019 firmware) which allows to pair any OBD device. See this post in the "Joying Android 8.1 Intel Airmont eight-core 1.8GHz SC9853i (4GB RAM, 32GB flash)" thread. This BT-app will only work till the next reboot, then it is completely disabled!
See also #27.
#15. Sleep mode: How much power is used? How long will it last? When does it really switch off?
This is mostly based on the previous Sofia 3GR and PX5 units, but I don't think it has changed as there was no change either between the (2) sofia model(s) and the PX5 model.
When switching off the unit it is not immediately in "deep sleep" mode. This takes about 30~60 seconds (on the PX5/Sofias ~4 minutes). In this period power usage is about 0.5~0.75A. When in "deep sleep" mode power consumption drops to 0.01~0.02A. A healthy battery can take this for at least a month.
After 5~7 days your unit will still be completely switched off resulting in a cold boot on starting your car. Just to make sure your battery is not drained. Nobody did ever exact measurements of this "switch off" period.
#16. A 3 seconds push on the PWR button switches off my unit, or a drag down (2X) from the notifiction bar enables me to shutdown the unit. Is there a difference with the Contact "switch off"?
Yes, there is. Pushing the PWR buton or dragging down the notification bar to shutdown the unit will only shutdown Android, not the hardware, and the energy consumption will still be above ~0.5A, but also makes it awake instantly. Switching off the car using your key, will bring the unit to "deep sleep". Then it will take 1-2 seconds to wake up again.
#17. I have a VW/Skoda/Seat unit with CAN-bus, but no Steering wheel buttons on my steering wheel. Will a 3rd party Steering wheel controller work?
No, not directly. These units come with a "VW motherboard" and do not listen to the Key1/Key2 wires, but only to the CAN-bus. Disconnecting the wires from the CAN-bus to such a 3rd part SWC-controller will not help.
The best solution requires some technical skills and involves an Arduino Micro-Pro device and is described in the [Joying for VW] Universal steering wheel controls with arduino by @bambapin.
(For a PX5: Another option is to resolder a resistor on your motherboard as described here).
#18. On long drives or high external temperatures (in the tropics) my unit doesn't work fluent anymore and apps start "stuttering" (voice) or slowing down. What is happening?
Install an app that wil monitor the temperature of your unit. The chips/motherboards in these units can get really hot. The CPU will "throttle" itself to lower CPU-cycles to cool down. Another problem of too high temperatures is that the lifespan of the unit will be shortened. And still another issue is that these units are "cold soldered", meaning that due to tension in the soldering due to the high temperatures, CPU soldering connections might be broken causing a non-functioning or mal-functioning unit. There are several threads on this forum giving examples of heat-sinks, fans and combinations of both.
#19. How can I use split-screen on this unit?
solution 1
Use the "Touch Assistant apk", which is the "white dot" floating top-left in your screen. It has a split-screen option and it remembers! that you are in splitscreen mode.
Solution 2
Start your "first" app and "second" app. Go to the task-manager (rectangle) in the top-right of the notification bar. It will show your active and last-used (but possibly closed) apps. Drag your "first" app to the left. In the right window you will now find the task manager with the other apps. Select the app you want on the right. (Of course this also works the other way round if you drag your first app to the right).
Note: This version only supports a 50%/50% split. Some Androids support 33%/66% splits as well.
#20. With every key press I hear this annoying beep. How do I remove it?
Solution 1
BEFORE (re)flashing your unit, edit the file “config.txt” from the firmware zip.
Add the line "ro.fyt.amp_switch=0" (or change that line from "ro.fyt.amp_switch=1" to this "ro.fyt.amp_switch=0")
Solution 2
1. Open the Settings app
2. Go to Device -> Sound -> Keypad Tone
3. Switch it off
#21. What is the default DPI on these units? Some apps/fonts seem too big or too small for the screen.
The default DPI is 160 for the 1024x600 units. Some screens are 1280x720. Some badly written apps (including my own JET apk) do not display correctly. On the 1280x720 screens you could go to a DPI of 180 or 200. Above that the Joying/FYT apps will not be displayed correctly. Changing the DPI is currently only possible if you have your unit rooted!
#22. When my unit boots, the radio is always started. Can I prevent this from happening?
You can't stop this. Not on a Joying and not on any other unit. And note that the radio app is actually only an interface that forwards commands to and receives data from the radio chip via the MCU. It is not an active app like your mediaplayer that does everything in Android.
When the unit boots, the hardware is up and running long before Android is. That means that the radio chip and amplifier are already working before Android has even booted. That is why you hear the radio. And that is why every manufacturer starts the radio app on boot: to enable you to mute the radio channel from the app.
The radio is never switched off as it cannot be switched off. It is only muted.
#23. Can I modify the lines/frames I see when having a reverse camera and driving backwards?
Yes, you can, but not from the app or Settings.
Unzip "190000000_com.syu.us.apk".
In /res/drawable you will find dl1.png to dl35.png, and dr1.png to dr35.png (left and right). These are used for the "frames" when driving backwards.
Change them, but keep the same resolution (size).
rezip the apk
use the "Creating an Allapp.pkg ..." from the "Modding your Joying/FYT....". Or in case you have rooted your unit you can directly replace the apk on your unit.
(There are more "frame" images in there, but I have no idea how to use them. Of course you could rename them if you want to use these)
#24. I only want to flash the MCU firmware, not the rest of the firmware. Can I do that?
There can be several reasons why you want to do this. Only(!) copy the "Stm32ud.bin" and the "lsec6521update" to a clean FAT32 formatted USB-stick/SD-card and put it in your unit. The flashing will start automatically.
#25. I want to flash a new firmware, but NOT the MCU firmware
Use your firmware of choice but remove(!) the "Stm32ud.bin" from the USB-stick/SD-card before flashing.
#26. Google Contacts sync? DON'T DO IT !!
When you flash your unit, you will most probably setup your Google account (Settings -> User -> Accounts). By default most of the synchronizing is switched on, including the Contacts sync.
Disable this as soon as possible!! Already since 2016 this is a bug in the FYT software. With sync on, the unit will delete all your contacts. (see video by John Molberg).
How to prevent this?
After setting up your google account, immediately disable Contacts sync.
When connecting your phone with your unit via Bluetooth, you can enable contact sync via BT.
Once your contacts have synced, I advice to alsodisable contact synv via BT. (Press the gear icon when connected and disable contact sync).
Note: After firmware flash always check your Google accounts contacts sync again. (The 20200407 erased my contacts again)
Tip: Export your contacts before firmware flash.
See this youtube video from John Molberg about the deletion.
#27. Improved Bluetooth Pairing (still far from perfect)
This is not a great solution. It is more a simple work-around.
Before flashing your firmware, you should update one line in the config.txt.
Set line "sys.fyt.bluetooth_type=1" to "sys.fyt.bluetooth_type=0". Now flash the firmware.
If you already flashed the firmware, you can do a "config.txt flash only" using my zip attached to this post.
See also #14.
#28. Order of Bluetooth pairing
Say you have an OBD2 dongle, it sometimes pairs immediately and it sometimes doesn't.
Disclaimer: Some will never pair. The Bluetooth ID-string need to contain OBD.
But:
your dongle is compatible, but it will still not pair.
your dongle is compatible but it will only pair using pincode 1234 (or whatever code).
First in the BT contect settings "forget" your paired phone(s). (Not only unpair but really remove them).
Now pair your OBD2 dongle. If necessary, first set the pincode in your unit to the pincode of your OBD2 dongle,
After having successfully paired your OBD2 dongle , you can now pair your phone(s) using the same pincode.
#29. Google Play Store does not start downloading.
This is a very annoying problem which I have regularly. It can be solved though.
Below options can be tried starting from the first. if it doesn't work, try the others one by one.
In the Play Store app, tap the "hamburger" menu (3-lines top-left) and select "My apps and games" (But probably you were already there). Remove all apps from the update-queue. Reboot.
Turn off auto-update for your apps.
Go to Settings->Apps, and clear cache and data from the Google Play Store app. Reboot/retry.
Go to Settings->Apps, and clear cache and data from Google Play Services (You might need to enable "show system (apps)"). Reboot/retry.
Uninstall Google Play Store updates.
Switch off downloading "only via Wi-Fi" (if also using a SIM card or if you can download via the hot-spot of your phone).
Turn off 4G data transfer and turn it on again (if you use the hot-spot from your phone, turn Wi-Fi off/on and/or mobile data off/on).
Sign out of your Google Account, restart your head unit and sign in again.
And you can look at this Google support article, or this one (more steps ..)

Nice Thread, will help a lot of people!
great thread!
Thank you for this! I realize you don't want people asking questions in this thread but more about posting solutions, so i'll attempt to add two I think are missing and you can always add your input:
Q: Everytime the head unit enters deep sleep, apps granted the Accessibility permission (such as Tasker, Automate, Launchers) might lose this permission. Anyway to prevent this?
A: This is due to services being shut off (post) when the MCU calls for deep sleep. There is no way to stop this. However, you can use FYTStarter APK (here) for restoring accessibility or other issues between 'deep sleep'.
Q: Third party apps and external keyboards are unable to control volume or other media controls. How to overcome?
A: Volume and some other keys/controls are preempted by the Joying/FYT software. You need to interact with the Joying/FYT services to control these aspects. This post here shows an example apk that can interact with Joying/FYT services to control volume and other aspects (and another version here and some easy to use apk for volume that are tested working here). You can write your own APK using same methods or take advantage of this apk to send intents/commands to control volume and so on. You can use Tasker or Automate to provide this control to other things. For example, use Automate to intercept 'VOL UP' from an external keyboard and then use APK command to send 'VOL UP' to Joying/FYT service (and thus restoring ability to control volume from external controls like Joycon controller or external keyboards).
Q: How can I interface Steering Wheel Controls (Can Bus or other) not supported by Joying/FYT drivers
A: You can always use Joycon interface adapter (http://www.exinterface.com/cpjexr/) to convert SWC and CAN bus commands into USB keyboard inputs. The Joying/FYT work with this but you do need to use third party apps to map keyboard inputs into meaningful actions (start an app for example). As mentioned in above Question, media keys might not work directly from keyboard (unable to control volume for example) and you need to work around that with additional APK, but it can be done.
Q: is there anyway to setup so that when i receive a bluetooth call, i can go back to [other app]?
A: If you have set Waze or [other app] as your Navi app (via Joying settings menu), tapping the Navi button on your screen should allow you to go back to Waze. But also: some apps can be allowed to take over the phone function. Example is Magic Earth and Osmand+. For both I can allow them to make/receive calls. It means that you see a bar on the bottom of the screen, but it is actually not the Joying dialer. So I am IN that app. Google Maps can do that as well and I assume Waze might be able to do is as well too.
Did you give Waze that authorization when Waze asked for it during first loading it? Because if you did, you are in Waze with a phone call overlay at the bottom. Therefore: you cannot go to Waze because you are already in Waze. (Quote from Surfer post)

All updates are full updates. You can skip all intermediate updates and immediately go for the last version.
Note though that you have to look at the MCU version: G32 or G32 (assuming you have a Joying SC9853i)

How can i know my mcu version? Like i see, in the last update from april 2020, there is only one link to download so i guess it good for all versions, no?
I also want to get some tips of it, maybe some recommended apps and etc..

There is no MCU update in the latest firmware, so you are correct.
No tips about recommended apps. Other threads are for that.
And personally I consider it ********. Everyone has his own preference for certain apps.

Check your system info.
You only need an OS or MCU update if something is bothering you. If everything works fine for you, don't bother to upgrade.
For me the necessity to upgrade is two-fold:
fixes for bugs that bother me like Google voice call. But after 3 firmware upgrades claiming they fixed it, they still haven't fixed that. Although I hardly answer to calls in the car, and almost never make calls, it is terribly annoying that every other brand unit (MTC, QD, Atoto, etc) can do that, including all built-in car brand media-systems, but not the FYTs.
Android security fixes. It is still not clear to me whether FYT includes security fixes in their new firmwares by patching their code with the offical Android security fixes. As I hope they are doing that, I still flash every new firmware to my unit. But that's just a blind hope that they do apply the security patches.

Where can I find the latest (and/or older) firmwares for my Joying unit.
You will find them on the Joying website www.joyingauto.com inside the blog: Updated firmware.
Should I always upgrade to the latest firmware?
Theoretically: YES. Bugs are fixed. New features are added. But..: sometimes new bugs are introduced.
Are there other Howto's, Q&As, Tips available?

Modding your Joying/FYT SC9853i unit without root: https://forum.xda-developers.com/an...modding-joying-fyt-sc9853i-unit-root-t3974357
Will all my apps and data still be there when I flash my unit with a new firmware?
That depends on the contents of the file "updatecfg.txt" in the firmware. See the explanation in post #1 of Modding your Joying/FYT SC9853i unit without root
Can I root my unit?
Yes, you can. See HowTo: Root Joying SC9853i Head Unit.
I have my unit rooted. How can I (relatively) easy install mods or tweak my unit?
Use the "Joying_Extra_Tools" app (also JET apk) which allows you to install Radio, Bluetooth, main server (nokill) mods and tweak/optimize (immersive mode, overscan, DPI, etc.) your unit.
All the apps are killed when the unit goes to deep-sleep. Can I change this?
The unit does indeed kill all apps upon going into "deep sleep", apart from a few system apps.
Solution 1
(No root required) By modifying the "skipkillapp.prop" as described in both post #1 and post #2 of Modding your Joying/FYT SC9853i unit without root, you can change this.
Solution 2
(No root required) Install a nokill mod using a prebuild flashable image from post #3 of the thread "Modding your Joying/FYT SC9853i unit without root". This mod deactivates the "kill_all_app" function in the main server app.
Solution 3
(root required) Install a nokill mod (using the JET apk). This mod deactivates the "kill_all_app" function in the main server app.
"Solution" 4
(No root required for "starting apps" activity) If you simply want "your" app available after deep sleep, a much "cleaner" way to do this is to use @bambapins FYTStarter apk that lets you autostart apps on "waking up" of the unit. See post #1149 of the "Joying Android 8.1 Intel Airmont eight-core 1.8GHz SC9853i (4GB RAM, 32GB flash)" thread.
Alternative: You can assign any app to the "Navi app" setting inside the Joying settings. You can use Tasker/Easer/Llama/MacroDroid/Condi/Etcetera to start apps/do actions, etcetera after wake-up. Note that for some of these actions you need root access.
I do not really care that apps are closed on going into deep sleep, but can I start some apps on waking up after deep sleep?
Like above topic: (No root required for "starting apps" activity) If you simply want "your" app available after deep sleep, a much "cleaner" way to do this is to use @bambapins FYTStarter apk that lets you autostart apps on "waking up" of the unit. See post #1149 of the "Joying Android 8.1 Intel Airmont eight-core 1.8GHz SC9853i (4GB RAM, 32GB flash)" thread.
If you are rooted you can use FYTStarter to start the accessibility service. It is not necessary for root to be kept active: it is enough to install and launch FYTStarter only once, while you have root. Later, even if you remove root, the app will still be able to start the accessibility services.
Can I make modifications to the apps on my unit without root?
On these SC9853i units, you partially can. See this Modding your Joying/FYT SC9853i unit without root
Are there Custom ROMs for this unit?
No, currently not. It is unlikely they will be created, but you never know.
The unit starts some default apps on certain hardware keys or "system actions". Can I change this (without root)?
Yes, you can for a number apps and a number of SRC/MOD Steering Wheel keys. see the "FYT HW OneKey app". It doesn't need root, but will also work with root.
I did something stupid and now my unit is in a boot loop or does not get past the boot logo. Help!
See post #4 in the "Modding your Joying/FYT SC9853i unit without root" thread.
The Bluetooth app can only pair a few number of devices. Can I change this?
Yes, but your device needs to be rooted. @seb21 has modified the Bluetooth app (based on 17 Sept 2019 firmware) which allows to pair any OBD device. See this post in the "Joying Android 8.1 Intel Airmont eight-core 1.8GHz SC9853i (4GB RAM, 32GB flash)" thread.
Sleep mode: How much power is used? How long will it last? When does it really switch off?
This is mostly based on the previous Sofia 3GR and PX5 units, but I don't think it has changed as there was no change either between the (2) sofia model(s) and the PX5 model.
When switching off the unit it is not immediately in "deep sleep" mode. This takes about 30~60 seconds (on the PX5/Sofias ~4 minutes). In this period power usage is about 0.5~0.75A. When in "deep sleep" mode power consumption drops to 0.01~0.02A. A healthy battery can take this for at least a month.
After 5~7 days your unit will still be completely switched off resulting in a cold boot on starting your car. Just to make sure your battery is not drained. Nobody did ever exact measurements of this "switch off" period.
A 3 seconds push on the PWR button switches off my unit, or a drag down (2X) from the notifiction bar enables me to shutdown the unit. Is there a difference with the Contact "switch off"?
Yes, there is. Pushing the PWR buton or dragging down the notification bar to shutdown the unit will only shutdown Android, not the hardware, and the energy consumption will still be above ~0.5A, but also makes it awake instantly. Switching off the car using your key, will bring the unit to "deep sleep". Then it will take 1-2 seconds to wake up again.
I have a VW/Skoda/Seat unit with CAN-bus, but no Steering wheel buttons on my steering wheel. Will a 3rd party Steering wheel controller work?
No, not directly. These units come with a "VW motherboard" and do not listen to the Key1/Key2 wires, but only to the CAN-bus. Disconnecting the wires from the CAN-bus to such a 3rd part SWC-controller will not help.
The best solution requires some technical skills and involves an Arduino Micro-Pro device and is described in the [Joying for VW] Universal steering wheel controls with arduino by @bambapin.
(For a PX5: Another option is to resolder a resistor on your motherboard as described here).
On long drives or high external temperatures (in the tropics) my unit doesn't work fluent anymore and apps start "stuttering" (voice) or slowing down. What is happening?
Install an app that wil monitor the temperature of your unit. The chips/motherboards in these units can get really hot. The CPU will "throttle" itself to lower CPU-cycles to cool down. Another problem of too high temperatures is that the lifespan of the unit will be shortened. And still another issue is that these units are "cold soldered", meaning that due to tension in the soldering due to the high temperatures, CPU soldering connections might be broken causing a non-functioning or mal-functioning unit. There are several threads on this forum giving examples of heat-sinks, fans and combinations of both.
How can I use split-screen on this unit?
solution 1
Use the "Touch Assistant apk", which is the "white dot" floating top-left in your screen. It has a split-screen option and it remembers! that you are in splitscreen mode.
Solution 2
Start your "first" app and "second" app. Go to the task-manager (rectangle) in the top-right of the notification bar. It will show your active and last-used (but possibly closed) apps. Drag your "first" app to the left. In the right window you will now find the task manager with the other apps. Select the app you want on the right. (Of course this also works the other way round if you drag your first app to the right).
Note: This version only supports a 50%/50% split. Some Androids support 33%/66% splits as well.
With every key press I hear this annoying beep. How do I remove it?
Solution 1
BEFORE (re)flashing your unit, edit the file “config.txt” from the firmware zip.
Add the line "ro.fyt.amp_switch=0" (or change that line from "ro.fyt.amp_switch=1" to this "ro.fyt.amp_switch=0")
Solution 2
1. Open the Settings app
2. Go to Device -> Sound -> Keypad Tone
3. Switch it off
What is the default DPI on these units? Some apps/fonts seem too big or too small for the screen.
The default DPI is 160 for the 1024x600 units. Some screens are 1280x720. Some badly written apps (including my own JET apk) do not display correctly. On the 1280x720 screens you could go to a DPI of 180 or 200. Above that the Joying/FYT apps will not be displayed correctly. Changing the DPI is currently only possible if you have your unit rooted!
When my unit boots, the radio is always started. Can I prevent this from happening?
You can't stop this. Not on a Joying and not on any other unit. And note that the radio app is actually only an interface that forwards commands to and receives data from the radio chip via the MCU. It is not an active app like your mediaplayer that does everything in Android.
When the unit boots, the hardware is up and running long before Android is. That means that the radio chip and amplifier are already working before Android has even booted. That is why you hear the radio. And that is why every manufacturer starts the radio app on boot: to enable you to mute the radio channel from the app.
The radio is never switched off as it cannot be switched off. It is only muted.
Can I modify the lines/frames I see when having a reverse camera and driving backwards?
Yes, you can, but not from the app or Settings.
Unzip "190000000_com.syu.us.apk".
In /res/drawable you will find dl1.png to dl35.png, and dr1.png to dr35.png (left and right). These are used for the "frames" when driving backwards.
Change them, but keep the same resolution (size).
rezip the apk
use the "Creating an Allapp.pkg ..." from the "Modding your Joying/FYT....". Or in case you have rooted your unit you can directly replace the apk on your unit.
(There are more "frame" images in there, but I have no idea how to use them. Of course you could rename them if you want to use these)
I only want to flash the MCU firmware, not the rest of the firmware. Can I do that?
There can be several reasons why you want to do this. Only(!) copy the "Stm32ud.bin" and the "lsec6521update" to a clean FAT32 formatted USB-stick/SD-card and put it in your unit. The flashing will start automatically.
I want to flash a new firmware, but NOT the MCU firmware
Use your firmware of choice but remove(!) the "Stm32ud.bin" from the USB-stick/SD-card before flashing.

No. That is no longer possible. That was only possible on the Intel Sofia models.

Thank you for reply, and I have a last question, I have put other firmware ( Teyes SPRO). Firmware was very good and fully functionnal except bluetooth.
I have mod allapp.pkg and fytmanufacturer with my number of head unit, the message "ui and mcu does not match" disapear is very good, but i don't now how to configure my Bluetooth for recognize in this firmware.
Bluetooth version is: GOC_V1.0/2019:07:18:16:59:52_gocsdk2
When i put other firmware he say: "unknow blink" How i can solve it ? mod file ?
Thank you for help.

The only reference I have is the bluetooth "blink_config.ini" inside "/system/res/bluetooth". Please check the differences between your original file and the Teyes SPRO file.
I am also very interested in this. Last week (or so) I already wrote that the T'eyes Pro FYT software seems to be way ahead of the Joying software. Can you share some insights? Pros? Cons?
Does Google voice calling work? And did it work on the Joying firmware?
