If it’s not the microphone (does it work with other apps? sound recorder etc.) then please continue here:

Phone calls: other person suddenly can't hear me anymore

Hi, I’m having trouble with phone calls on my FP2. It works fine for a while, but after some time (so far a span of anywhere between 5 and 35 minutes), the other person suddenly can’t hear me anymore. I can hear them just fine. This has happened three times in the past two days, once while I was on a street tram (so moving), the other two stationary in my office. Any ideas what might be going on? Is anyone else having similar problems?
