When I am on a phone call, suddenly the person I am talking to can't hear me (as if I have pushed the mute button, but I haven't). I can continue to hear them - as they say "can you hear me, are you there". Even happened when I was on the phone with tech support - she stayed on for over 5 minutes talking to me but could never hear a response from me. She had no solutions. When I take the phone away from my ear, the keypad is visible and I don't have the options of speaker phone, mute etc. I REALLY don't want to have to switch everything over to a new phone. Anyone else have this issue.
