Frozen screen on iPhone 13
My screen is frozen at a game app ad. If I try to turn the phone off by pressing and holding either volume button and the sleep button down simultaneously, the phone emits a whooping sound until I release the buttons. No power off slider appears. I can answer calls, read text messages, and swipe from the NE corner to the SW corner to get to the quick actions page, but that's about it. No other screen buttons work except turning the flashlight on/off or setting a timer.
How do I resolve this?
