I have issues with Fold 4 call volume on the car kit after the One UI 5 / Android 13 update. I can make and take calls, but volume of calls drops or raises unexpectedly without touching the volume controls.
Before the update call volume could only be modified throughout car volume control, but now after update the volume can be altered also from phone buttons, which I think it's an issue of the Fold 4 Bluetooth profile after update.
Anyone experienced issues with bluetooth working differently after the OneUI5 update?
I tried re-pairing, deleting profiles, cache etc... not working.
Maybe a future update addresses the bug.
Here the same problem please help us
