Sudden AOKP ROM problem ???

I had flashed AOKP 21/2 build. It was working great for a week with little overheat problem . Nothing serious though . But from today onwards it started restarting on its own. It happened couple of times and now all the bugs people have mentioned starting showing up. It makes that crackling sound when headphone is inserted and won't recognize it . Network won't come after the restart. That brightness fluctuation and almost everything. Does anyone has the same problem ? Cause for a week it was working great. even my video recording was fine.

Try AICP - https://forum.xda-developers.com/k5-plus/development/rom-k5-plus-t3536263
It is the most stable rom i found till now and VoLTE also works pretty well.

Why stock rom ?? VoLTE works on custom roms

The modem you have installed must have come from a stock om with volte support in order to continue to enjoy volte on your custom rom. the custom roms do not provide anny modem software and hence if your stock rom did not have volte you will not have it after flashing a custom rom.

Reflash the stock rom.After that if you want to flash any custom kernels then try blackbox kernel(latest one).It supports MiUi roms

Camera errors any custom rom N7100

I have problem. Galaxy Note 2 with custom rom. In stock rom 4.4.2, camera works fine. But when i install a custom rom (Android 5.0 Lollipop and higher version) camera stops and other problems like can't video call in whatsapp etc. Can someone knows why and solution? Can we change ROM's camera and libraries with stock camera and libraries? I dont know maybe camera libraries wrong or have a bug. I tried many custom roms (Android 6.0.1 Beanstalk, Lineage OS 7.1.2 etc.) but camera never be good quaility without crashes. Please help me and sorry for my bad English
Screenshot: Whatsapp video call in BeanStalk Rom Android 6.0.1 Marshmallow
I just flashed latest Resurrection Remix on my GT-N7100 for the first time and the camera doesn't work either!

Have you asked in the ROM thread? Happens with all camera apps?

I tried another app and the front camera works, but not the back one. Though with the default app I couldn't even test the front one, it closed immediately.
I know for a fact the camera worked fine before flashing the custom ROM, so it's not a hw failure.
When as the last time you checked the camera with a stock ROM? I searched around and there don't seem to be many people with this issue on the note 2. Your phone's model # is gt-n7100?

Yup, GT-N7100.
Last time I checked the camera was just a few days ago. And yeah I've searched for the issue a bit as well, didn't have an luck unfortunately...
Have you tried this ROM? --> https://forum.xda-developers.com/ga...-aicp-12-1-official-nightlies-t3569395/page85
I being using it as a daily driver for months, and it's the best one I ever had for this phone.
Few times I've had camera problems, but automagically resolved just after restarting the phone.
Give it a try, and let us know it this was an acceptable solution.
Best of luck.

[GSI] [treble] Android 9 pie Bluetooth in call problem

I've tried all treble pie roms and in all are the same problem with Bluetooth in call sound. First I thougt it's a problem with my elephone u pro, but in the meanwhile I've recognized that the same problem exist in many phones.
I'll hope that we can support the developers with a payment if they fix this problem.
I am willing to pay up to 50$ if someone is able to fix this problem for the elephone u pro.
If there's someone else who wants to get the problem solved then please write here your payment offer.
But it would be a shame if people make an offer here and do not stick to it later.
Root first, then go to Vendor/Overlay/BluetoothResCommon.apk
delete it,then reboot,

1. You have to extract stock /vendor/etc/audio/audio_policy_configuration.xml and delete A2DP related section like this:
https://github.com/PixelExperience-...mmit/977444af69f10fc135d07e19f1e5f1183e73e9ff
then replace it (by root explorer or creating magisk module).
2. You also need to change /system/bin/rw-system.sh.
Please delete
Code:
mount -o bind /mnt/phh/empty_dir /vendor/etc/audio || true
and save.
NOTE: This works only on CAF based custom roms. It doesn't work on AOSP.

Hi
I've tried, but the changed and saved file
/vendor/etc/audio/audio_policy_configuration.xml
will be automatically deleted at restart.
The folder is empty after restart.
Any ideas?

Great job! Bluetooth In call is working.
I'll think it's not your development but for your know how to, I've send you 15 Euro.
Do you know also how to get Bluetooth audio music working?
By any chance did you get fully functional Bluetooth on the gsi rom or anyone else?

I'll hope so. 
 @AndroPlus has already fixed in call and may be he's on the way to solve audio also.
Has it been rectified in all builds
so is it safe to say that we can install the latest version of GSI provided by rom providers made in and released in march.
I would like to know that before i go ahead and transition over from stock to custom rom... mainly called PixelDust Pie rom version march

No, the fix needs device specific path and not all GSI has it.
I have the Razer Phone and have got either audio working or in call but never both... I am in the process of going through both audio routing files and see if I can combine them to get it to work, but I haven't messed with Android in years so it's taking more time than I anticipated to get caught up on all the changes you guys have made. The last time I built a rom was when treble was just on the discussion table. It really amazes me this bug has gone on this long, but maybe there's more to it than I'm seeing so far. I have seen some good devs working on this.
Enlighten me Please

Hey @AndroPlus , could you possibly explain how to go about it. I would appreciate the help. I have got a nokia 7 plus with pixel dust pie rom on latest version running. Where and what do i need to do to get it up and running on my phone. I need to get in call bluetooth running. Thats the only thing stopping me from using this amazing blazing rom
Bluetooth music also does not work with me. However bluetooth calls work, so its weird that music/audio is not working.
Bluetooth music also does not work for me, but bluetooth calls work fine. I'm using Arrow GSI with Mi Mix 3.

It's on resurrection remix pie, also headset over usb c is working. Only audio sound over Bluetooth is a problem. Do you've got a solution ir an idea what should I can try?
Btw do you have any idea how to control the led colours?
i still have no bluetooth calling on Mi Mix 3 on the @AndroPlus rom's so his solution definitely doesn't work for all devices.
furthermore there is still a bounty to get bluetooth working perfectly on vanilla android gsi's

No changes in audio_policy.xml were needed - only removing this line from rw-system.sh

Hi, fortunately it's a software issue, all you would want to do is to just Unlock the phone's bootloader, flash TWRP recovery, root the stock rom with magisk and finally install a good custom rom such as Free Roms or Infinity Os, all of which would remover this issue permanently....
