auto rotate not working 5.0.1 topic

Hey all, i recently flashed the factory image for 5.0.1 and all of a audden auto rotate stopped working. It did fall put of my picket from about 3 feet onto the ground. Nothing externally was harmed . however, i cant remember if i had issues wuth rotating the screen after flashing the factory image and before i dropped it... Im wondering if anyone else has experienced this from either a physical drop or from a bad factory image flash. Thanks...
