"Screen overlay detected”Is an annoying Marshmallow problem, not yet solved by Google, present in any device that mounts the release of Android Marshmallow, both 6.0 and 6.0.1.
It's annoying because it doesn't give you the ability to edit application permissions, whatever they are, from the Android settings screen due to a pop-up. So when does the “Screen overlay detected” message appear? Mainly it comes out on two occasions.
If we want to change the Authorization of an application, whatever it is, and at the same time a Chat head is open, or a bubble in the foreground, of an application, such as, for example, Facebook Messenger, or a service is running of an application that acts on the management of the display, such as, for example, Twilight and Clean Master.

Now that we know what causes it, we also know how to prevent it from happening so that we can change application permissions without the problem of "Screen overlay detected". There are two solutions to follow:
- first close any Chat head by dragging it on the large “X” in the lower part of the display or in any case closing it following the procedure provided by the application that generated it;
- uninstall any type of third-party application that generates services that act on the management of the display.
After these two quick and easy steps, you can activate or deactivate application permissions from the system settings without the pop-up of "Screen overlay detected”Cause any kind of annoyance.
