My screen = locked. (I use the standard screen lock) When I swipe to unlock, haptic feedback starts freaking out. Also, the bar which you're to swipe starts wobbling in the center of the screen, and won't proceed all the way through, leaving me with a locked screen. I've tried swiping the screen with keyboard exposed, too, thinking that the change in orientation may work as a quick fix. That didn't work either. What can i do?
