iPhone XS Max stuck on Apple Logo
My iPhone XS Max won’t power up. It is stuck on the Apple logo for about 15 minutes then screen will go black for another minute or so and then go straight back into the apple logo.
I have tried the volume up, volume down, hold power button. The iPhone will flash and then I let go when the Apple Logo reappears. But it gets stuck at this point again.
There is no water damage to my knowledge. I do not have a computer with iTunes and would prefer to resolve this without having to wipe the device, if possible.
Any information helps! Thanks in advance.
