Lenovo Tab 2 A10-70F with Carlinkit Carplay dongle--problem - Android General

My Lenovo Tab 2 (6.0 Marshmellow stock, unlocked, not rooted) refuses to work with my latest acquisition (Carlinkit Carplay dongle from Aliexpress). The wired plus wireless dongle works on any android above 4.0 and I've tested it on phones from Android 5 to 7 without a problem.
However with my Tab 2 (which I was going to install in my car as a handsfree and navigation unit paired with my phone), it simply refuses. One has to install an app called Autokit (address on vendor's page in Aliexpress) on Android device. When I connect my phone via wireless, it attempts many times and either fails and starts all over, or the screen goes blank (with phone saying it's in carplay mode), or gives warning "The navigation machine [i.e. my tablet] does not support current settings. Please disconnect your phone and enter the Settings page to enter compatible mode."
In settings page I have three "working modes"--speed, fluency and compatible. I understand them to be resolutions: full HD, HD and lesser (VGA?). I get this message on both speed and fluency. In compatible mode, I briefly see the screen loading before it hangs and disconnects.
If I attach phone with dongle with a cable, the app does not react at all and still goes on wifi and blueooth looking for a device.
However in other phones I've tested on, I've had no problem with either of the three modes, or cable phone-to-dongle connect.
Questions:
1. Is it possible to upgrade/ change settings on Lenovo Tab 2 to accept my dongle or is it a lost cause?
2. I understand the dongle has its own wifi and bluetooth, and doesn't rely on cable. Therefore, it must be some USB protocol in the tab which is causing difficulties (as dongle works fine on other phones). Is this logical?
3. If so, there ought to be a better way than disposing my trusty Tab 2 and shopping for a used tab which will accept my dongle?
Thanks.

Connect PS4 controller (DS4) - NO ROOT!

So I am posting this everywhere as I found very little information about how to do this and trouble shooting some issues. Made a reddit post and going to post it here (I hope this is a proper place to put this).
Just hold down the PS button and Share till the light starts to flash. Go to your Bluetooth and pair the game controller.
Trouble shooting suggestions are on bottom.
Now after about 30sec, and for some unknown reason, you will run into input lag. To fix this you will need to download an app called Bluetooth Auto Connect. Once installed goto Advanced Options - Connect Now. Once you push Connect Now the input lag should be gone.
If you are looking for a clamp I just bought something called Nyko Smart Clip - PlayStation 4 on Amazon for $10. TOTALLY WORTH IT!
Trouble Shooting:
I had an issue when pairing that it would see the device but wouldn't pair. What I had to do was turn off Bluetooth, turn it back on and try again.
Another issue I had was Bluetooth Auto Connect wasn't fixing the lag issue on my Samsung Note Pro (same device I had an issue pairing, my Samsung Note 4 didn't have any of these issues). I had to uninstall sixaxis controller then restart device. Then uninstall Bluetooth Auto Connect and restart device. Then connect DS4 controller. Then install Bluetooth Auto Connect and spammed Connect Now. It seemed to work. FYI my Note Pro is rooted but my Note 4 isn't and this works on both devices!
To repair the controller to your PS4 plug it in with your charging cable and push the PS button, it will pair immediately. I personally bought a 2nd controller so I wouldn't have to do that.
Hello, I tried this with my ps 4 controller and it says that the controller is paired but the light on the controller keeps flashing and it does not respond to any input and after some time it just turns off, the Bluetooth auto connect app just says that is unable to connect to wireless controller, please help, my device is a galaxy s7 edge.
Connecting the PS4 controller works for me but can't do anything else such as can't play games or anything, maybe a future update when everyone starts to cry a bit more about how the S7 Edge isn't compatible with any controller, I have tried 3rd party controllers and the right joystick and the rest of the buttons do not work, the only thing that works is the left joystick...
Before the 7.0 Nougat update on the S7 Edge (SM-G935P) the OTP (wired) connection would crash the phone; freezing the display, hard reboot. This happened on the OFW and rooted versions. Bluetooth would pair but you'd have to try multiple times and you'd need to delete the original pairing to repair (holding the pair buttons on the controller).
After the 7.0 Nougat update, controller support had been added- albeit horribly. The only connection is an OTP connection, Bluetooth still has errors. The button configurations are wrong though, the controller is useless. Square, X and circle are all wrong and triangle doesn't even register.
This is where I'm at, anyone know of any fix? I'm not looking forward to buying a Stratus XL (works perfectly but it's 60$)
I'm about to just switch from Samsung to Sony lol.
Unfortunately the guy that wrote this article is guilty of blatant douchbaggery (what good is a paired controller that cant be mapped and starts mapped completely out of whack). Yes you can 2 button pair a ds4 controller but a ds4 controller is encrypted and requires in linux and linux like os a driver called SCP (SONY CORP.SOMTHING......) That just isnt offered by any app ive seen on droid other than sixaxis. Alternately you could always hard wire it . The major flaw in this is the inability to stop the controller from charging in this case off your phone battery. As far as the mapping goes the only issue is android uses the generic abxy combo which is cross circle square triangle in ps4 speak . in retrospect .....i suppose i should have stopped reading when the author claimed no root. The controller keylayout files (.kl) are located in/system/user/keylayout. How are u supposed to do anything to those w/o root?

Cellular Dongle (3g, 4g LTE) on MTCD?

Hello,
I have a Joying 5.1.1 HU with RK chip which has absolutely horrible Wi-Fi connection. I recently got a freedompop account (Sprint's network) which gave me a wifi hotspot.
I plan on taking the sim card from the wifi hotspot and putting it into a LTE USB dongle (either Franklin U770 or Netgear 341U for Sprint bands).
1. Is it as simple as plugging in the dongle to one of the USB ports on the back of the Headunit?
2. Is there possible compatibility issues between brands of dongles?
Thanks.
Better to buy the dongle at Joying website, to avoid compatibility issues...
Inviato dal mio SM-G935F utilizzando Tapatalk
1. Yes, if your USB 3G/LTE dongle has already pre-configured (also, not PIN enabled), mine works this way.
2. Yes, you may refer to some of the threads/posts here or in MTCB forums for the list of compatible dongles. I have 2 3G dongles on hand but only one worked.
Also, mine has "USB3 is not mounted" issue quite frequently since I started having the dongle plugged in. I have tried to switch between the 2 ports given and also flashed a few ROMs, to no avail, same thing happened. Not enough power maybe? Still looking for an easy fix. Maybe a seperate Mifi could work or I stop playing music from USB instead.
Erisin (LM) MTCD unit. This works for me:
1. Huawei E220: disadvantage is that it needs two USB slots, one for additional power, else won't work properly
2. Huawei E367: not recommended, because it's dual-mode (includes USB storage mode). By default it's in USB storage mode, to make it work I have to use PPP3 Widget after root.
To answer both your questions:
- yes, compatibility issues can occur, check MTCD thread on pda4, there is a list of tested modems. Other than that, you need "Mobile Network Settings" apk, if you don't see the menu in settings, so you can configure the APN.
Hi. i would like to know if there are any compatible 4G dongles ... ?
This may be useful to you - I currently have issues with using a WiFi dongle on my XTRONS GS MTCD.
The head unit boots in about 1s from standby, but the WiFi dongle (XTRONS 3gdong008) takes about 20-30s to boot.
If I want to get nav / streaming music running, I have to sit there for ages while it turns on and connects.
Very annoying - I've gone back to using my mobile as a hotspot for now.
I'm considering adding a permanently live USB port and leaving the WiFi dongle always running, although I'm not sure if this is going to drain the car battery while parked overnight.

Wireless Controller Problem

Hello.
For the last two days I have been trying to make my OMEGA Wireless Gamepad (a copy of the PS Dual Shock controller) work on my Galaxy J7 2016 (6.0.1).
It connects to the phone through Bluetooth as a input device no problem but it won't work further than just that.
I even rooted the phone to try some stuff out but to no avail.
It stays connected but none of the buttons do anything (not in phone menu, not in PPSSPP, not in a bunch of keymapper aps).
So I was wondering is there a way to get this fixed without me having to buy an Micro USB to USB Adapter and trying that out.
Thanks for reading.

Control phone with broken lcd

Hi
I have Galaxy Ace 4 (kitkat 4.4) with broken lcd. The screen is blank but touch should work. Earlier something was visible on screen and as I remember touch was working.
Moreover, the system had some failure due to permanent "application xxx stopped working" and factory reset should be made.
I would like to use this phone as wifi hotspot. Is there any way to access the phone after factory reset? I have found application like Visor to control android via usb on pc. But developer mode has to be enabled and I'm not sure if system should be rooted.
Thank you for any help
If you can still see the screen, but the touch screen does not work:
Buy a cheap USB adapter so you can connect a PC keyboard or mouse (probably a USB C to USB A adapter). You can buy these adapters from China on eBay for $ 1 (but you may have to wait a month until they arrive in the mail. In this case, buy from a seller in your own country). I suppose you have a keyboard or just use the keyboard and use the arrows to move and select things, so I think the Windows button will become the home button. Press Enter to select and Escape to return. Or you can simply point and click with the mouse. The problem is that not all phones support "OTG", so you may not be able to read the adapter. If so, then I think you have no other choice. . But most of the stores themselves definitely support 100% OTG, so it should work normally. The problem with Bluetooth is that you need to pair it first, which requires touching the screen. Therefore, if you cannot touch the screen, using a Bluetooth mouse or keyboard may not work
If you can't see the screen, but the touch screen works normally:
Unless you change the screen, don't think that there are many things you can do. Android phones that were previously compatible with MHL allow you to use a dongle to connect it directly to HDMI. But the cell phone no longer has that function. If you have a Samsung phone, I think you can buy a Samsung Dex docking station, which will allow you to connect it to the screen via HDMI. If you can install applications on your phone, you may be able to control your phone from your computer using a screen mirroring application (there are thousands of different software that can do this, but you need to install applications on your phone). Same as Google Chromecast screen mirroring. .You need to access the application on your phone to perform this operation. Therefore, there is nothing you can do except replace the screen. If you are lucky and your smartphone supports some type of HDMI dongle adapter or some type of desktop docking station with HDMI output, you can view the phone's screen and access it.

Question Bluetooth connectivity issues

I have been experiencing issues connecting to devices over Bluetooth. Sometimes it just works, other times it doesn't work at all, and some times it kinda works but not right.
All of these issues are resolved by restarting the phone, but that isn't a solution because the issue comes back.
3 Devices I have been having issues with
1. S Pen - Sometimes it won't connect to the phone, I get an "S-Pen Missing" message and it will not connect. If I t ry to connect to it manually via nRF Connect (The Nordic Semiconductors Bluetooth App) it tells me that the BLE device has a GATT error. It happens semi-randomly but I can always make it happen by doing #2
2. Car Stereo - This is the weird one, it will connect and play music, but it will not do "calls" if I connect to Discord it won't recognise the car as a Bluetooth device it can route to.
3. Raspberry Pi - This one it appears it will connect to ONCE, and then after a disconnect it will not connect again.
Again, each of these can be fixed by restarting the device, but they happen again after a while. The pen & RPi use BLE, I don't know what the car uses for calls.
Turn off global power management completely in Device Care.
Network reset, reboot and clear system cache from the boot menu.
Ok, I've done a network reset, and cleared the cache partition. I checked Device Care for something like global power management, and I couldn't find anything. Most of the pwm settings are off except the "optomise daily" setting.
I'll let you know later if I have the same issue again.
These, this is a N10+ running on Pie.
To check if you have disabled global power go to Developer options>standby apps, all buckets should show as active otherwise power management is enable.

Are those the only three devices you connect via BT? What other apps do you use that need to use BT (i.e. Galaxy Wear, Apple Music, etc.).
You mentioned "Nordic Semiconductors Bluetooth App." I looked it up. Why do you need a third party generic BLE connecting app? It seems to me that could be the problem. You shouldn't need a third-party app to connect your BLE devices. The S22U's native pairing will work with any BT device that adheres to BT standards.
Try uninstalling the nRF Connect app and see what happens.
The only other Bluetooth devices I have are other in-house hardware, running on SiliconLabs BGM13P chips or NRF52840 chips...
The NRF app isn't a replacement for your bluetooth pairing app, its a debugging app... it can connect to BLE devices and show their GATT profiles, update devices that have Nordic's OTA update code and copy a devices GATT profile to act as a BLE Server.
We use it for testing and debugging.

Ok. I recommend uninstalling nRF Connect anyway. If anything, to rule out the app. How old is your car and the Raspberry Pi? Even though BT 5.2 is backwards compatible, sometimes older BT devices won't work with newer devices. That doesn't account for the S Pen issue though.
I uninstalled nRF connect, and changed all the settings you both recommended. Exactly the same behaviour when I went to leave work. My car stereo would do music but not calls, then when I restarted my phone, it worked. Then when I got home, my S Pen would not connect to my phone, then I restarted my phone and it worked.
Its not a problem of not being compatible, its a problem of something stops working.
Please also note that these devices worked fine together in the past. I am concered that it is either a change made by an update or a Bluetooth chip that is faulty....
OP- Have you debloated at all and if so maybe you've removed something relevant that might be causing these issues?
No, stock image, no OS modification beyond the things that Samsung offers (GoodLock and Stock customisation)
I have our in-house apps for interacting with our equipment (over Bluetooth) installed, but #1 they shouldn't affect anything if they are not open and #2 they don't do this to ANY of our other test equipment.
I would just like to say, that I appreciate the assistance that you are all offering! I have used many forums over the years when looking for support on things and I rarely find a place that is more ready to try and help than XDA forums!

I've seen the issue of the spen disconnecting but only a couple of times and the issue worked itself out within a couple of minutes with me not having to do anything.
I've also have had a couple of wonky issues when connecting a new Samsung phone to my car. I've narrowed down my issue to the fact that when I transfer my data & settings via Samsung smart switch, it includes the details of my Bluetooth pairings. To fix it, I have to go in and delete my Bluetooth phone settings from the car and from my phone and re-pair them.

As cool as I think Smart-Switch is as a program, I actually never use it when moving from one phone to another. The junk that Google drags with me from one phone to the next is already too much, I like to use a new device as a chance to do some housecleaning. So no old-data oddities here.

Hmmm.. Ok. You're probably right about the suspect causes. I know there is a code you can dial to get into diagnostic mode, I just don't know what it is.
The only other option you can try (as a last resort) is to factory reset it. If it is update caused, a factory reset MAY fix it. If you take it to a service center, send it in for repairs, or do a warranty replacement, they're going to factory reset it, or have you reset it.
have you tried running diagnostics in device care ?
or check with this dc
android
Bluetooth test*#*#232331#*#*
samsung
Bluetooth Test Mode*#232331#
I still haven't done a factory reset, but I continue to have the issue.
I have run the BT Test in device care, it always reports good.
I tried the codes, neither of them work as the first one is for vanilla android and the second is for older versions of Samsung firmware.
I've tried completely unpairing from the car radio and re-pairing, disconnecting and connecting from the other device to no avail.

I'm not entirely sold on the idea that it is a hardware fault. It could be a hardware limitation; meaning you cannot connect to more than a certain number of devices simultaneously. I don't know how many BT devices you can connect to at once. I know at least two simultaneous connections (I've only had two simultaneous connections at a time).
You said you have other BT devices in your house other than those three your having issues with. How many are there? How many are you connected to at any given moment?
Is it possible that you have too many simultaneous connections?
When you try to connect to your car.. Did you check under BT connection (your vehicle) to make sure both audio and calls are checked..

Unless having multiple connections causes the BT to fail completely, no. Even after turning the car off and walking away, it still will not connect to the S Pen. The only BT devices I use with that phone regularly are:
S Pen, Car (Music & Calls)
At work I develop devices that use Bluetooth and I sometimes connect to them, but only ever one at a time.
