Why won't Samsung Galaxy Core Prime won't let me select none for screen lock after suddenly locking itself?
Screen lock. Locked it's self after no service for 24 hours. Now can't get it to stay unlocked. Each time I open my phone I have to put in passcode. Want no lock screen on.
Go to Settings > Personal > Lock screen and security > Screen lock type. You'll be prompted to confirm your password. Enter it and click next. You will then have the option to set your lock screen to None.
