This may seem elementary..but I had the same problem..couldn't hear sh*t on the phone, no matter what tweaks I did. It ended up being my little sister who actually "fixed" the problem. We removed the screen protector that shipped with the phone. It was covering up the actual ear piece. When I removed it, sound came in loud and clear. I am not worried about scratches either as I ordered an invisible shield from zagg and their template has a hole pre-cut for the ear piece.
