I bought the phone 4 month ago, and works perfectly…Yesterday i foud a problem.I was talking with my friends on skype,when someone called me,and from that moment,my microphone stopped working. When i call someone they cant hear me at all. I have tried to factory reset the the phone, and also to install another Firmware, but i cant solve the problem. Please help.
@false123 you maybe want to consider cleaning the microphone.
I once had a similar issue with the audio jack. It was filled with dust - no idea where it came from though.
If you can, blow some air into it. Best would be using a compressor for that, but be careful when doing so.
