Turning off the screen overlay on Samsung Galaxy S7 is one of the most confusing error messages which is afflicting some Galaxy phone users. Of course, there is a fix which is relatively simple.
The issue is mostly showing up when users start up an application for the first time and they accept the usual permission dialogs. More precisely the message goes off like this: Screen overlay detected – To change this permission setting, you first have to turn off the screen overlay in Settings > Apps.
As an example for what screen overlay is, the most known is the chat heads in Facebook Messenger. It is actually a part from an application that can display over other applications. The real problem lies in the permission of when to use the screen overlay. It would be of a great use if the users have an option to disable this when installing their desired application.
The fix is in doing exactly what the dialog box is telling you to do. It goes off like this:
- Launch the Settings app
- Tap Applications
- Click on Application Manager
- Tap on More to open the menu in the top right corner
- From the menu click Apps that can appear on top
After finishing step 5, there will be shown a list of applications who need permission to use screen overlay. After you find the application that is causing you a problem with screen overlay, what you need to do next is just tap the toggle button next to the name of the app to turn the permission off. You should have in note that not always is precisely shown which app is trying to use screen overlay. Sometimes you might need to think by yourself which application can change the way of showing the content on your display (like the Messenger from Facebook for example).
After you are done with turning off the overlay, all that is left is just restarting the application. Now everything should be running just fine, but you may also be asked to grant the permission back again.
