How can I change the unlock pin so no pin is needed to unlock the screen. It's a real pain to have to do this every time the phone goes into hibernation. Galaxy s4. every time I try, the "none" is greyed out.
That looks to be setup by whoever configured the phone, often through a security policy setup by a company. That disables shutting off security pins. If this phone is not managed by a company, contact your service provider and have them look into it, it may be a stolen phone.
