I did the factory reset and it's still behaving funny. The way the sensor went out of calibration is that I dropped it the other day and the battery fell out when it dropped. When I use apps that measure the tilt of the accelerometer, it's returning a value, so I know it's working, it's just that something has happened since the yesterday.
Any other ideas?
