You open your Android App for the first time and are interrupted by a screen overlay message – a feature called ‘Draw over other apps’. What does this screen overlay message mean? This actually allows part of an App to display over the top of other Apps.
Facebook Messenger is one such App that uses a screen overlay. Apps need your permission to use screen overlays as sometimes they can cause problems, or could trick you into granting it permission to do something you might not want. If you are using Android Marshmallow and you have just installed an App and are greeted with the following dialogue:
“Screen overlay detected. To change this permission setting, you first have to turn off the screen overlay in Settings > Apps” – Click on OPEN SETTINGS
You should now see a list of Apps that use the ’Draw over other apps’ feature. You can tap on any App that is listed to turn off the screen overlay permission.
Alternatively, you might want to disable a permission from Settings > Apps. Tap that permission and you will presented with the same dialogue as above if screen overlay is used by the App. Click on OPEN SETTINGS. You can only disable that App permission by disabling the ‘Temporarily turn off overlays’* toggle. You will now need to go back to > App permissions to disable that permission.
*This turns off active screen overlays for 2 minutes. You will need to turn off overlays temporarily when app app asks you for permissions or to turn an app’s permission on or off.
Note: From ‘Draw over other apps’ – You can also tap > Menu (top right three vertical dots), to show all the system Apps that use screen overlays or Reset app preferences (this will turn on all screen overlays).
