Samsung Screen overlay is a feature that allows one app to appear over the top of the other. Like Facebook messenger chat heads, or you may have an app that changes the color of the screen. Using the Screen Overlay feature of chat head helps you instantly reply while using other applications.
In some conditions, the Screen overlay detected an error that you’ll see in certain situations. Screen Overlay must be disabled when granting permission to other apps, such as the Camera. If it is enabled while granting permission, an error will appear.
This is because the overlay can cause confusion and mislead a user to provide unwanted permission, such as access to personal information. Make sure to only grant permission to trusted apps.
If you see a Screen overlay detected error, it’s caused by a conflict between a running app and a newly installed app requesting permission to display info on multiple screens (e.g., messengers, alerts, battery status, etc.). This step-by-step guide will show you how to turn off Screen Overlay to stop the error popup.
