i woke up this morning to find my iphone 5s screen black, still had sound but the screen was non responsive. Please help.
I was using sleep cycle whilst sleeping so the phone screen was still off.
iPhone 5s, iOS 9.2.1
Have you tried resetting your device: Hold down the Home and Power buttons at the same time and continue to hold them down until the Apple appears (up to 30 seconds - no kidding). If the Apple appears, then you should be good to go once the Slide to Unlock screen displays.
Cheers,
