I know this is going to sound wack, but for the last 5 days my iPhone 6 has locked up, screen locked, from 12 noon EST to around 1 PM. I kid you not. I have to hold the side button and round button to get it to react but even when I do, it just locks up again until around 1PM. Friday was so bad it wouldn't restart so I plugged it in to the computer. It took about 2 minutes but it started up. The phone is fine all other hours of the day. Any thoughts??
