My wife's Motorola Droid Razr locks-up and becomes totally unresponsive anywhere from 15-20 times a day. She has to go through the Pwr/Vol- reset procedure to get it to do anything. Sometimes it will lock-up as soon as 5 min. after doing this and it's REALLY starting to bug her. Has all current updates, does not have MotoCast installed. Cannot correlate it with any particular app or use activity. It has been this way ever since she got it and Verizon only wants to replace the phone. This is the 5th phone she has had since starting out with a Samsung Galaxy Stellar last fall which must have been a lemon. Every phone in the string of replacements, both new and referbs would wind up unusable with multiple issues until she finally got the Razr, which, other than these maddening reboots, seems to work OK. I got an identical Galaxy Stellar at the same time and have had very few problems with it and love it, but what's wrong with the Razr? Is it her magnetic personality?
