Note

By bypassing Android's security measures, this application may potentially make your device vulnerable to unauthorized apps. It is essential to read the following information and use this app with caution:

Reason for Button Lock

Android has a feature called "Alert Window" or "Toast", which allows content to be displayed in front of regular apps. Exploiting this feature can lead to unintended operations known as "Tap Jacking Attacks". To prevent this, certain buttons have security measures in place, resulting in their lock if content is displayed in front of them. Generally, stopping the app that displays content in front of the button will release this security.

About Tap Jacking Attack

In a Tap Jacking Attack, an illegal window is displayed in the foreground, allowing the user to perform illegal operations such as downloading and installing unauthorized apps, fraudulent billing, granting illegal permissions, and more.

About Locked Button

Locked buttons will not change color or respond to taps. In Android 6.0 or later, tapping a locked button may display the following messages:

• "Because an app is obscuring a permission request, Settings can't verify your response."
• "Screen overlay detected." To change this permission setting, you first have to turn off the screen overlay from Settings > Apps."
