When i installed mine I swiped to unlock but it would not move all the way over to allow me to enter my pin. It froze about half way and i couldn't access the column of 1,4,7. I hard rebooted the phone and when it came back it seemed to be ok.
Reboot the phone. Go into settings \Accessibility. Turn off the Zoom setting which is on due to a bug. Because of how your screen is while zoomed you'll have to figure out where to tap to flick the slider. Reboot the phone again. Fixed.
