IPhone X - “Notification Cancelled” message & Apps won’t open it, froze
I call emergency by mistake and I was able to cancel the call. My IPhone froze and was not able to turn off my phone. Thanks for one of the users that posted the solution.
press the up volumen button for a second and release , then down volumen and release , finally the on and off switch press and release make sure on all buttons do not press for more than a second .
iPhone X, iOS 12
