Iphone 4s screen goes black once it gets to the lock screen.
Iphone 4s screen goes black once it gets to the lock screen. The phone then says enabling curtain mode. If i take a screenshot on the phone with the power and home button it turns the screen on for the flash of the screenshot then turns off again. Dunno if i've enabled something in settings or my phone has got full retard on me.
I don't really wanna factory reset my phone becasue i haven't got a back-up and i can't peform one becasue i can't unlock my phone.
iPhone 4S, iOS 7.0.3
