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
Go to Phone Settings --> Developer Options --> Simulate Secondary Displays
and turn it to None
.
If you don't see Developer Options
in the settings menu
(it should be at the bottom, go Settings ==> About phone
and tap on the Build number
a lot of times)
