The screen is broken and it doesn't appear in itunes
So i am starting kind of a little business where i live by repairing iphones everything has been useful but i got this iphone with a a broken screen, so i wanted to test if it was just the screen so i connected it to a computer to charge it but after 30 minutes it doesn't appear in iTunes so i don't know if the phone works or what else needs to be fixed, is there a way to diagnose that?
Is this a good question?
