My mom bought a SGT 10.1 used off amazon and for some reason the auto rotate wont work properly. Could the accelerometer be messed up and if it is is there a fix for this problem?
Check in the dockbar...
tap the clock and open it up... there should be a scrollable list of items you can toggle on and off, and one of them is auto-rotate. Make sure that this hasn't been inadvertently hit (I did this myself a little while back, and it's kind of easy to click it, if you're not lucky).
Hope that helps.
