Not sure if this has been asked but once a week my iPhone screen will become unresponsive. Home button won't take it home and power button doesn't do anything. I can still use what ever app I'm in and if i get a notification i can swap over to that app. The only fix is a hard reboot. Any one else experience. Also separate issue, once a day my screen will randomly get a pin wheel and then go to home screen but all apps are still open, think i narrowed it down to snap chat but not sure.
