I have a Samsung Galaxy note 10.1, and the screen rotation before was noticeably quicker. It just recently started to take another second or two to rotate. On top of that, everything on screen will freeze until the animation is complete. I am not rubbing that many applications when this happens. It will happen even if I reboot. I am using only a forth of the ram and storage and power saving mode is off. What could cause this, and is it fixable?
