I have the Samsung Reality and just the other day it started acting up. First it was stuck in landscape mode on the screen then this morning it just kept switching between landscape and portrait mode on the screen and when you hit the lock button it would lock then cut back on then the lock screen would go away and it would go back to switching modes again. Eventually it just got stuck on the lock screen and you couldn't go anything. The touch screen wouldn't work and the buttons wouldn't work, so I had to take the battery out to turn it off. Has anyone else had the problem or doesn't anyone have any suggestions?
