HELP!! I'm on my 2nd brand new HTC One from Verizon in the past 2 weeks, and both phones have the exact same issue. During a call, the microphone that picks up my speaking voice intermittently and suddenly stops working and people on the other end of the line say they can't hear me anymore? It happens on about 50% of my phone calls. It's maddening! If I put speakerphone on it works fine, and if I use ear buds it works fine, but in the normal phone mode when holding up to my ear, is where the problem occurs. The proximity sensor is working fine, and I'm not accidentally hitting the mute button with my cheek either. I'm thinking this has something to do with the fancy "Sense Voice" functionally on the phone using dual microphones and noise cancellation to supposedly try to enhance the sound quality. Yeah right. The telephone phone function one this phone is basically unusable. What is the fix for this problem! Software update? Can I disable Sense Voice? Help!
