I tried to install third party app given here at XDA developers forum but somehow didn't manage to complete the installation. Let me remind you that "Unknown sources" were enabled.
When i opened apk on my phone i got to list what this app can access on my phone (normal) but when i hit the "Install" button nothing happened. Only "Cancel" button was clickable. So i thought something was wrong with APK. file.
But then the same thing happened with different APK. At that moment i realised something was wrong and asked Google for help.
It turned out an application was responsible for this. This guy had the same problem, but with different application.
Anyways, after i uninstalled lastly installed application everything was back to normal. App that caused my head aches is: https://play.google.com/store/apps/d...esture.overlay
I really busted my head with this one, so i thought i might share,
