My droid razr maxx continuously turns on and off. It boots up and shows reception and message alerts at top but before I can do anything it keeps shutting down with 5 seconds of full boot up. There is not time to do anything before it shuts down again. The battery is charged. It felt hot at the time it started doing this. It has now been a day with the device off and the same result. Any others experiencing this problem or know a solution?
