Glitch appears when boot up!!!!

Hi

When iPhone is on press the power button down & hold down at the same time press the side volume down button hold both down until you see apple logo this can take 30 seconds.

Also go to i books download ios 11 user guide & iPhone 8 user guide both are free.

If you still have a problem return to apple store.

Cheers
