Has anybody seen this? My iphone flashes an apple boot logo after a few seconds of use. It is not actually booting, but just flashing the logo while normal use. Then the screen goes black.
It can't hurt trying to boot into safe mode. Turn off your phone, then while holding the volume up button, hit the power button. Don't let go of the volume up button until you see the lock screen. If that works, try a normal reboot.
