Tested on 2 Qualcomm devices with phh android 12 based gsi.

For now, I can't enable A2DP and fix Bluetooth in call at the same time. Feel free to tell me if you find a way.


------------------------------------------------

This guide provide workarounds for many Bluetooth problems, such as:
1. Can't open Bluetooth
2. Can't connect to Bluetooth devices
3. Can't use Bluetooth audio
4. Can't use Bluetooth in call

------------------------------------------------

After finished the following steps, your device will have both Bluetooth audio (SBC, AAC, Aptx, AptxHD ,LDAC) and Bluetooth in call working.
1. remove /vendor/overlay/BluetoothResCommon.apk (if presented) (if presented and deleted, wipe Data and reinstall your gsi in case it didn't take effect)
2. remove /vendor/etc/a2dp_audio_policy_configuration.xml
3. Enable "Force-disable A2DP offload" in phh settings
4. Enable "use alternate audio policy" in phh settings if you face any problem in sound and/or volume adjustment (if you got multi ones in different feature category, try different combination until it behave normally)(may require reboot)
5. flash Magisk module "aptx-HD-magisk-10_arm.arm64.zip" to fix aptx support

Now everything mentioned above should work.
