[Galaxy Note 4 Android Development (Snapdragon)] star53:
The reason: the "Screen Overlay Detected" error message appears if you are using a so-called floating application (for example, floating Facebook notifications) and a freshly installed new application that you just opened for the first time. It is indeed during the first opening that the application will ask for certain access rights and creates a problem of compatibility.

Affected smartphones: On the Internet, it is mainly on Motorola and Samsung smartphones that the problem occurs. At AndroidPIT, we were able to show the worry with a Samsung phone.

Affected applications: we managed to recreate the problem with the Drupe application. According to several posts on the forum and on the Internet, it seems that applications like CleanMaster, Lux or Twilight can trigger the error message. Of course, this list is not exhaustive.

The technical explanation: apparently, it is a security measure of Android when applications are requesting to operate at the same time. In theory, you need to disable the screen overlay to fix the problem.

The temporary solution to the "Screen overlay detected" problem

Step 1

Open the settings

Click on the Search icon or type directly in the field provided at the top right

Look for "Overlay"

Alternatively: Settings> Advanced settings> Overlay with other applications

On some Samsung, you can also use this method:

Open the settings

Applications> Application Manager

Click the Plus icon at the top right and select "Applications that may appear on top"

On the Galaxy S8, for example, simply go to the "Applications" menu of the parameters, then click on the three points at the top right and enter "Special Access". Look for "Applications that may appear on top" and you will see the list of applications.

2nd step

A list of applications will then open to you. You must identify the problematic one and temporarily disable it from other applications. Here are some tips to quickly identify the application responsible for the problem:

Do you see a floating notification on the screen? This application is certainly the cause of the problem. You can hide the app or deactivate it in the list.

Do you have an installed application that changes the colors on the screen or adjusting the brightness? These applications may cause the "Screen Overlay Detected" error message.

CleanMaster may be causing the problem

Vuos still have not found? Deactivate the apps one by one to test.

All you have to do is uncheck the problematic app. © ANDROIDPIT

Step 3

You can now launch the application that requests a new authorization. You should no longer see the error message.

For Samsung users: If this still does not work, the One-Hand Operation mode may be causing the problem. I advise you to turn it off: Settings> Advanced> One-hand operation.

Step 4

If you really want to make the application work, you have to reactivate it. I advise you to activate only the applications you use.

A definitive solution soon available?

We could see in the Developer Preview that this problem may well be doomed to disappear. The riasons that pushed Google to make this change are quite obscure and this is not good news for everyone since many applications will no longer work properly, but at least this should fix this problem.
