Note:tested only on GSI ROMs 9.0

1. Bluetooth audio connection fix
Backup the file /vendor/overlay/BluetoothResCommon.apk
Simply remove /vendor/overlay/BluetoothResCommon.apk via root explorer

2. aptX HD
Install "Bluetooth stack audio bitrate changer for SBC + aptX & aptX-HD enabler" from Download of Magisk Manager or Download Here (APTX for Android Oreo & Pie NOT WORK)

3. build.prop
Open /vendor/build.prop and find "persist.vendor.bt.a2dp_offload_cap=sbc-aac" and replace "sbc-aac" to "sbc-aac-aptx-aptXHD" (Add -aptx-aptXHD)
Note: if you don't find the add "persist.vendor.bt.a2dp_offload_cap=sbc-aac-aptx-aptXHD"


4. Restart device and test

Note: if it doesn't work undo everything you did thanks for trying :D

This guide made bluetooth audio and connectio work, but bluetooth calling is not working. Can call but no sound is transmitted, so i cant use it. Any suggestions as how to proceed?

I worked.


Thanks :good: :). I actually did look at the thread before, but had the impression that the GSI Treble roms were of the ASOP variant, contrary to the note: 'NOTE: This works only on CAF based custom roms. It doesn't work on AOSP.'

Am I wrong, or is it the note that does not apply in this case?

I tried these solutions on the Lenovo Z5 pro GT, but the Phone won't recognise any bluetooth IEM's. The sound keeps playing over the speaker. Does anyone have a solution?

in all the GSI images i installed audio BT is not working.

And BluetoothResCommon.apk is not in that path, why ?

build.prop is there but there is no "persist.vendor.bt.a2dp_offload_cap=sbc-aac-aptx-aptXHD" entry


Any help to fix bluetooth for this case ? I can pair, to headphones connect, for a moment seems to work, but finally audio get played in the phone itself.
