"After getting Android 6.0, I had a problem that Android keeps asking me to give apps permissions and when I was about to give the permissions, a window popped up saying 'Screen Overlay Detected'. I cannot use apps because of this 'Screen Overlay Detected' message."
The 'Screen Overlay Detected' message was found on Samsung S8/S7/Note 8, LG, Pixel and many other Android phones that run on Android Marshmallow and above. This article will show you how to fix screen overlay detected with effective solutions that have been tested by thousands of users.
# What Is Screen Overlay Detected?
Screen overlay, also known as the feature called draw over other apps, is an advanced function coming with certain apps which allow the apps to draw over other apps - that is to cover or create some stuff to appear on the other apps. For example, Facebook Messenger Chat Head can inform you of a newly received message when you are watching a movie on Netflix or playing a game. That's screen overlay (Draw over other apps) feature is working. In fact, it is a dangerous feature. Imagine this: some malicious apps create some things to cover your screen while you are using other apps so that they can trick you into tapping buttons that they want you to press. Therefore, the Android system is strict with screen overlay permission for the sake of users' interests. Normally, the app cannot get screen overlay permission unless you grant it to the app.
And once the screen overlay feature is active, the Android system will not allow you to make sensitive changes, such as granting permissions for an app, on your phone for your security. For instance, when you are trying to give location permission to a recently installed app when Facebook Chat Head is active, the "Screen Overlay Detected" message will pop up, stopping you from granting the permission. To conclude, screen overlay detected issue is a conflict between apps with screen overly permission and the newly installed apps asking for permissions.

If you don't want to waste many efforts to manage apps permission, you can directly uninstall the unused apps possibly with screen overlay. Screen Overlay feature is often used by some unwanted security and cleaner apps. Below is a list of apps which can possibly cause screen overlay detected issue on Android device:
- Facebook Messenger
- Android cleaner apps
- Night Mode apps such as Twilight
- Security and Antivirus apps, such as 360 Security
- DU apps such as DU Booster and Cleaner, DU Battery Saver, DU Antivirus
- Other apps, such as Es File Explorer, Share IT, Internet Speed Meter, LUX App, UC Browser
If the above workarounds are not useful because you are not sure which app is causing the screen overlay detected conflict, then you can manage permission in the "Safe Mode", in which all third-party apps are disabled on your phone. Different versions of smartphones have different ways to enter into safe mode. I will introduce how to enter Safe mode on devices of Android 6.0 or later and you can search online if this way doesn't suit your phone.
Step 1: Press and hold the power button of your phone until "Power off" appears on the screen.
Step 2: Tap and hold the "Power off" for seconds until a pop-up prompt asks you to confirm whether you want to enter into safe mode.
Step 3: Tap "Ok" and your phone will restart into safe mode.
After entering into safe mode, you can go to Settings > Apps and give permissions to whatever app you want to use but can't because of the "Screen Overlay Detected" message.
There are two apps which can help you manage screen overlay detected error: Install Button Unlocker, which enables you to give permission which you cannot be given because of screen overlay apps; Alert Window Checker, which can present you a list of running screen overlay apps.
