I have been using Droids since they have come out and very familiar with them. I recently (three days ago) upgraded to the Razr Maxx HD and went to plug it in to charge (i already powered down) and when I plug it in to charge, the phone comes back on. I shut it off, while plugged in, and it power off and then turns right back on again. I have tried all combinations and can't get it to STAY OFF while i'm charging. Suggestions?
