Android Microphone issue on OP3T

[sharktale1212]

For some reason my OP3T's microphone has stopped working during calls. My first reaction was that the microphone went kaput but voice recording works, so does the Google Now app. Then there were tons of tuts out there which talked about disabling and enabling Google Now. But that doens't work too. Any ideas on this?

Turns out my sim slot glitched. Restarting the phone dint work. But when I put the sim in Aeroplane mode and back everything worked fine.
