Pattern Lock on Galaxy S2 fails after device is rebooted
Posted by Bernard Chandler on 01 December 2014 09:09 AM

This issue has been observed on the Samsung Galaxy S2. 

When a policy enforcing a passcode is set for a device, the pattern lock will work until the device is rebooted.  After that, the device will require a higher level device unlock, such as a PIN or password.  Previously exposed options such as None, Slide, Face unlock, and Pattern will be greyed out and will be marked as Disabled by administrator, encryption policy, or credential storage.
