Apple make you completely reset the phone when you hand it in for any type of repair
I’m guessing the repairer will need to turn phone on and do some screen tests?
Maybe ask the repairer what they usually do. Make a backup either way just incase you have to reset the phone
Ahh no way. Lol. Pretty cleverI read this is to stop you tracking the phone and finding out locations of of places they don't want you to know about
Does Samsung's maintenance mode disable the networks?
