I have the SB i7/16/512. I notice periodically, seemingly at random, I get this message that says "Autorotate On" that pops up in the upper left hand corner of the display. This is occurring when docked to the keyboard. After this, I can confirm that Autorotate is indeed on, as when I rotate the device (even with the keyboard attached) the screen will change orientation. If I undock and redock, autorotate goes back off for some time, but will eventually come back. So it seems there is either a software or a hardware bug, and whatever software controls autorotation is erroneously thinking that the keyboard is detached. Is anyone else seeing this problem? I searched for, but didn't see any posts on it. If it's a hardware issue specific to my SB, I want to go ahead and return it while I still can.
