My Razr Maxx has developed a random oddity. Every now and then (maybe every couple of weeks) the screen will start flickering as if it's repainting all of the pixels as white, then back to what they should be. I cannot see any degradation in performance or function other than the screen flashing. It seems like it starts slowly and speeds up for a few seconds, then stops as abruptly as it started. There's no apparent cause, and no apparent pattern to when it happens. In fact, it's so random that I've had a hard time capturing it with another camera...until today! A brief 30-second video can be seen here to show what I'm talking about. The phone is approaching 2 years old and thus well out of warranty, but I've taken very good care of it and it's in excellent condition (no drops throughout its lifetime). Has anyone seen this before? Anyone have any ideas about what's causing this, and what (if anything) can be done about it?
