When I place or receive a regular call the other person can barely hear me unless I speak less than 1 inch from the microphone. At less than 1 inch, they hear me good. At 2 inches extremely muted (this is the distance of the mouth in a regular call), and at 3 or more inches nothing at all.
Physically the mic however works fine when recording videos, so it has to be something non-physical.
In desperation I used flashtool and re-image the whole thing (even with erasing all data) with the latest XpriFirm ROM and tested it right after the successful image and without installing any 3rd party apps. The problem still there.
I also tried 3 different ROMs from different countries, but the problem still there.
Using a external wired headset mic works fine.
It seams, like a setting that is aggressively reducing the mic sensitivity just for the phone calls.
Ruled out 3rd party applications, mic physical damage or normal Android setting, I am really lost on to proceed from here! :(
Does anyone know what to do?
