I have the same thing happen to my Inc. it's frustrating when this happens but by doing soft resets an some other minor adjustments to my incredible i've been able to minimize the issue. B33
I read somewhere in the forums that this is mostly happening when the phone is on 4G. Supossedly, if you switch to CDMA mode in settings, it will not happen. Worth a try. I do not have 4G, so it has never happened to me.
