My wife has the Droid 2 and she has been having continuous problems with the phone hanging up on her calls or dialing her voice mail while in a call. I have had several calls hang up on me as well. I have checked how she holds the phone to make sure the proximity sensor is working and everything appears fine. She has even tried pressing the power/lock button as soon as she enters a call with no improvement. Has anyone else seen this problem and what can be done to fix it?
