No sound or mic during calls only.
So I've seen this problem on a few forums. The phone works fine unless you make a call. When you do, the mic and the speakers will not work. They function with any other application in the phone. The suggested fixes are firmware update (some claim this has worked) and the other is a reflow of the chip that handles the incoming calls(?). I know by the teardown which chip handles the sound on the board, but if anyone has encountered and fixed this issue before, could you give a brother a hand on where to aim the heat?
