Does anyone else's incredible squeak while being handled? If I tighten my grip even a little while holding it in my palm, it squeaks. It happens on the sides at the top of the phone, the side of the phone, and the bottom of the phone. The squeaking at the top and bottom of the phone aren't too bad, but it's pretty loud on the side. It's gotten to be very annoying, and I can't figure out why it's doing it. The back cover clearly isn't sitting flush with the rest of the phone and i'm not sure what to do. Should I take the back cover off and try to "tighten" it up on the side? Any suggestions? Thanks!
