Having a strange issue where if my alarm goes and I snooze it with the red slider and I inadvertantly auto-rotate to landscape and back again in the process, I am unable to unlock my phone to turn the alarms off permanently as some of the keypad is missing, i.e. no number 3, 6, 9. The keypad also only populates the top half of the screen. Have to wait for another alarm to go off to make it reappear. Anyone else have this?
