OK... I have discovered why many of my calls have problems with answering. When I pick up the phone, I realize I am hitting the camera button inadvertently. The phone then goes epileptic and can't do anything but try to take control of the camera lens (of course, answering the call isn't as important.) It's the same issue as the volume indicator going up and down and the need for something like ring guard. Couldn't they have put the camera button somewhere else, even at the top of the phone where you don't usually press when picking it up?
Motorola did a good job of initial design but so many of these things could have been solved with a modicum of QA!!!!
