I found a security bug in the module, which locks applications. When I run a secured application in the window mode for instance in Samsung Galaxy Note 3 (such a mode is avaible in many smartphones), the notification for PIN code or a password appears in the background in the full screen and the application in front of it in the window and I can do with it everything, what I want without typing password or PIN. The protection doesn’t work in such a case. This is very dangerous, because many and many present smartphones have the ability to run applications in the window.
