These applications are designed to work on phones that require FRP (Factory Reset Protection) bypass after gaining access to the browser. The method of using them can differ depending on the phone model and its Android version for example, Android 10 works differently compared to Android 7. However, for newer versions like Android 15, especially on Samsung devices, these apps may no longer be effective. That’s why it’s important to check a YouTube guide that matches your specific phone and version to understand how to properly use these applications.
