Rispondi a "Black Screen and lock button not working... What should I do?"My iPhone 4 screen went all black this morning. I was using assistive touch, so I can't reboot it together with the lock button, witch isn't working to power off anymore. I tried to connect it to iTunes but I need to access the screen to unlock it. Location services was off to save battery, so I can't reboot it with find my iPhone. I didn't back it up on icloud or itunes, which I was going to do it this week. I was hoping to back up the data and find a way to reboot it. I have called from another phone and it's ringing. I have connected the charging cable, but it doesn't show the charging icon either, probably because it's still with battery power. Anyone has experienced something similar? Many thanks in advance.
