I've never had the "vibrate" issue. The issue I'm having is when I answer it automatically puts the phone into mute and speakerphone and then the screen becomes irresponsive and frozen and I need to do a battery pull. If I wait till the other person hangs up it causes the phone to force close repeatedly over an over till I do a battery pull. I'm in the process of tryin to switch out kernals and see if one makes a difference but when playin with kernals its never a short process for me, usually takes a couple days. In the meantime thanks to everyone that responded to this thread.
