iPhone keeps turning off, showing shutdown screen
My iPhone SE keeps randomly showing the power off screen. When I cancel, it shows the lock screen and my fingerprint isn’t recognized. When I do shut it down, the Apple logo flashes about every 5-15 seconds and won’t stop until I connect to a charger, so I can’t reboot my iPhone either. When I touch the power button, nothing happens, but I think it’s connected to the problem.
iPhone SE, iOS 13
