microphone and ear-speaker don't work for calls
I have an unbranded Galaxy I9300 which worked fine all time. I've tried different firmwares but it doesn't seem to work anymore.
The problem is only there when I try to call. I can record with no problem with the audio recorder. And all speakers also works fine. So hardware seems to have to problem. Only when I do a phone call. No speaker and no microphone!
Currently I am running "ArchiDroid_V2.1.2". I've also tried different modems. But I actually don't know which one would be the best for Germany.
Can you help me anyhow? This must be fixable.
Is there probably another call app which I can try?
