If “screen overlay detected” has suddenly popped up on your smartphone’s screen, you’re in the right place. Here we’ll explain why this message is appearing, and how to make it go away. Follow this step-by-step guide to handle it the right way.
Error message “Screen overlay detected”: the cause
The problem: Android suddenly warns you that a screen overlay has been detected.
● The reason: This message appears when you’re running a floating app, and then start a newly installed one, which requests access rights. Common floating apps include the chat heads of Facebook Messenger that can appear floating above other apps.
● Affected Smartphones: Users across the internet have reported experiencing this problem on Samsung and Motorola smartphones, among others. AndroidPIT managed to replicate the behavior on a Vodafone and a Samsung smartphone.
● Problem apps: We replicated the problem using Drupe, but ES File Explorer, CleanMaster, Lux and Twilight have all been blamed for the problem.
● The technical background: As a security measure, apps ask for permission to use certain parts of your phone (internal storage, camera, etc.). In theory, a display overlay can interfere with the dialogue requesting permission, so you need to disable the feature to interact with the dialogue.

The solution: a step-by-step fix
Step one: “Screen overlay detected” fix
Find out what apps have permission to draw over the screen. 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
Step two: check app permissions
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 are some pointers on how to identify the app that’s causing the trouble:
● Do you see an app bubble on your screen? If so, 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.

Step three: re-try the app
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.
Step four: 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 only the apps that you actually use.
Step five: use safe mode
If the above steps don’t work, there’s an additional step you can take to try and fix the issue. This requires you to use the “safe mode” Android feature to manage the app permissions.

This method requires you to remember the app you’re having these issues with. (e.g., if it’s WhatsApp, Facebook Messenger).
● First, press the power button of your phone.
● Press and hold the Power Off option on the pop up prompt.
● After holding it for a few seconds, another prompt pops up, asking you to enable Safe Mode.
● Choose OK, the device will reboot in Safe Mode.
● Now, when your phone has turned on, go to Settings, and then to Apps.
● Here, scroll down and find the app that suffered from the screen overlay problem, select it.
● On the app page, select Permissions.
● On the Permissions page, enable all the permissions the app was asking previously.
● After this is done, reboot the phone.
It’s 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. Newer versions of Android don’t appear to suffer significantly from this problem, and it seems to be mainly reported by users of Android Marshmallow.
