Reason why this button is blocked
The Android was equipped with the “alarm window” or “toast” function. It’s the ability to display the layout before the normal app.
When this feature is taken advantage of, a user could inadvertently perform an operation called a “Tap Jacking Attack”.
Android has set security on a few buttons to prevent this from happening. If the layout appears in front of the button, the button is locked.
Generally speaking, security is broken by stopping the app that is showing the layout in front of the button.
About Tap Jacking Attack
An illegal window appears in the foreground, and a user can improperly work as follows:
・ Download and install the illegal apps
・ Fraudulent billing
・ Grant illegal permission, etc.
Via the locked button
The locked button does not change the color even when typing.
In Android 6.0 or later, you might see the following message when you tap the locked button.
・ Since an app is hiding a request for permission, the settings cannot verify your response.
・ Screen Overlay Detected To change this permission setting, you must first disable the screen overlay via Settings> Apps
・ Update libraries.
