My razr maxx has quit vibrating on text messaging and backing out of forums. I can lightly tap on the side of the phone and it will vibrate again. I called Verizon today and he had me run the phone in safe mode for a couple of hours to see if it still did it. It did. He also told me to disable my smart actions. He said that they can send me a factory certified replacement if I want. Has anyone had this problem and if so any ideas on how to fix it? Also, is it a good idea to accept the factory replacement? I just don't want to get a "new" phone and the battery be horrible
