I am suddenly unable to unlock my phone without a pattern, pin or password. This just happened after I updated the Verizon protection app today. There's nothing that I can do on my SG4 in the Settings and security other than uncheck the allow administration access and try to disable it in the application manager. I have restarted and then removed the battery as well without any success. I wouldn't have a issue with the lock screen if the available time to put in a pin or pattern etc.. was long enough before the screen goes black again.
