black screen
Brand new iPhone X . 256gb 11.3.1 (15E302)
Worked perfectly for a week.
Went to setting and switched on the magnifier. After a little while the screen went black . Does not respond to tapping.
Tried to re-boot but cannot insert the pass code as the screen only lights up for a split of a second
Never connected the phone to a PC>itunes hence cannot reset the phone using itunes.
Any idea?
iPhone X, iOS 11.3.1
