Since I updated to 2.2.1 (OTA) this morning, the auto rotate is really slow! It takes about 3 seconds to change orientation every time I rotate the phone. I restarted, calibrated horizontally and unchecked and rechecked the auto rotate option, but nothing seems to fix this. It was not a problem before the froyo update. 3 seconds is a long time to wait to rotate the screen! Thanks for any ideas you may have.
