I was playing a game this afternoon, and suddenly the screen flipped upside down. At first I thought it was a bug in the game, but shortly afterwards I noticed that immediately upon opening the camera, it too flipped upside down. Looking through the different apps, I see they are all messed up. I went and purchased "AccelGraph" to see what the hardware was reporting, and I found the following: Those images are taken while the phone is laying flat on a table. It seems to be jammed at +2.3G on the Y axis. Is there anything I can do to recalibrate it? I have tried restarting it, but no luck. Thanks in advance!
