How fix “Screen overlay detected” (Error)

The reason: This message appears when you’re running a floating app, and then start a newly installed one, which requests access rights. Floating apps include the chat heads of Facebook Messenger that can appear floating above other apps.
Affected Smartphones: Users across the internet have reported experienc this problem on Nokia,Samsung and Motorola smartphones. It seems likely to affect many manufacturers. AndroidPIT managed to replicate the behavior on a Vodafone and a Samsung smartphone.
Problem apps: We replicated the problem using Drupe, but CleanMaster, Lux and Twilight have all bee blamed for the problem.
The technical background:  A security measure, apps ask for permission to use certain parts of your phone (internal storage, camera, etc.).  A display overlay can interfere with the dialogue requesting permission, so you need to disable the feature to interact with the dialogue.

1-“Screen overlay detected” fix

 On a non-Samsung smartphone, follow these steps:
  • Open the Settings
  • Tap the magnifying glass at the top right
  • Enter the search term “draw”
  • Tap Draw over other apps
  • Alternative route: Apps> [gear  icon]> Draw over other apps
For Samsung users:
  • Open the Settings
  • Then Applications > Application manager
  • Press on More > Apps that can appear on top


2nd step-
You will find yourself in front of a list of apps that have permission to use floating buttons or other screen overlays. 
Now you need to identify the problem app and temporarily deny it permission to draw over the screen. Here is are some pointers on how to identify the app that’s causing trouble:
  • Do you see an app bubble on your screen? If do, this app is almost certainly the cause. Either you hide the app bubble or disable the app in the list
  • Do you have an app installed that changes the colors on the display or adjusts the brightness?
  • Reportedly, Clean Master can be a trouble maker. If you see Clean Master in the list, disable it
  • If there’s no obvious cause, disable everything

3rd step-

Now you can try launching the app again, and it should request permissions without the “Display overlay detected” error getting in the way.

For Samsung users: We have also received a report that suggests the one-handed keyboard setting could be the root cause.

 Deactivate it by going to Settings> Advanced features > One-handed operation

 
   

4th step- reactivate screen overlays

In order for the app(s) that you have disabled in step two to work again, you need to re-enable its overlay permissions. If you turned off all apps, it might be worth considering only reactivating those apps that you actually use.

This is a rather inelegant workaround, but it’s the best we have until Google makes the necessary changes to prevent app overlays from interfering with permission dialogues.
