Recently I've had people complaining a few times that they can't hear me during a call. I tested the microphone in Diagnostics and also recording in a Voice Recording app and it was very weak (I had to speak very loud for it to register even 1-2 bars). But the problem seems to go when I restart the phone. The mic is back to normal. Then after a while the problem returns. Any suggestions? Will a reset help or is it a hardware problem?
Thanks,
P.
