I've had some problems off and on and constantly had to reboot for auto-rotate to work. After the last Android, it completely stopped working. Don't know if the update was related or not. The Check my Android app shows sensors 1,5, and 7 non-functional. I've tried about else turned up by Google except ripping it open -- not too keen on that. In the meantime using one of the free rotate screen apps available. Any other suggestions?
