My iPhone 6s was updated to iOS 11.0.2 recently. After that I began experiencing various unresponsiveness problems. Today it got even worse; my phone's display is 100% unresponsive when unlocked. However, when locked the display works as normal. So I can use the camera, browse the lock-screen widgets, and use Siri. This means I can make calls to people in my phone book. But if somebody calls the phone, it rings but there's no option to answer the call.
I cannot reboot the phone as the power on/off button on the side won't show the slider to turn off the phone. However, that same button works to lock the phone.
This doesn't appear to be a hardware problem as everything works (save for the power off function) when the phone is locked.
I tried to reset the phone in iTunes, but it wouldn't let me because "Find my friends" must be disabled first, which I obviously cannot do.
What are my options here? I'd like to resolve this quickly as I'm traveling abroad today and need my phone. I can think of only two things:
- Make the battery run out and hope that something changes when I power the device up again. I can drain the battery faster if I light up the flashlight
- Enter a wrong passcode over and over until the phone resets itself
