My iPhone's camera stopped working. App opens but the shutter never opens. It holds still forever. It just came suddenly without any warning.
My iPhone was Jailbroken and I thought it was something to do with that (though it didn't make any sense as I had it Jailbroken for a couple of years now). So I installed the iOS from scratch (restore) without Jailbreaking it. Restored the backup. Camera worked... for a day.
Stopped working again. I tried Camera+ - no luck either, freezes on the "autofocus" rectangle.
What's happening and how to get it to work again?
I'm fine with Jailbreaking it again if there's any point (like need to access system files...).
