I have a Lumia 920 on AT&T. For quite some time now I have to use a Bluetooth headset in order for people to hear me during a phone call. If not, all I get is complaints that they can't hear me. I don't believe that the phone hardware is defective. Too many people have the same issue. Hoping that the 1314 Firmware will fix this issue. Don't know if it is proximity sensor related or what.\
Has anyone found a legitimate fix for this issue?
