Does someone know how to turn off this screen?
Also phone has a message (Toast) when trying to make a screenshot:
Unable to capture screenshot. Prevented by security policy
.
One of recommendations was to update policy, but didn't help: Menu --> Settings --> Lockscreen & Security --> Other Security Settings --> Security Policy Updates

The answer is
You must have either disabled, froze or uninstalled FaceProvider in settings>applications>all
This will only happen if it's frozen, either uninstall it, or enable it.
