I have a slightly different issue. The call quality will be fine. But all of a sudden, after some 20-30 seconds, the call will be going on but the other person cant hear a word that I say and I also can't hear anything from the other person. For around 10-15 seconds, the call freezes. Then again I can hear the other person all of a sudden and it will be fine. The again after 5-10 seconds the same issue occurs. It is happening during every call and I am getting very annoyed. Any idea what the issue might be? I have tried stock rom, cm12 based roms, different kernels as well. Still the issue persists.
I am also facing the same issue ..Have u found any solutions??
