I was swiping from one page/screen of apps to another, and my phone froze! I tried turning it off and hard reset, but it simply didn’t respond. It was weird. It would lock automatically and unlock with Face ID, but none of the buttons or swiping worked. And it stayed frozen between pages/screens. Before calling Apple, I decided to try plugging it in and that “fixed” it. I hope this was a one time incident. Anyone else have something like this happen?
