TB Checker – Safetynet Root is an app for checking the safety of your mobile device, specifically for Android.

What is the purpose of the app?

This app is designed to be used by safety specialists, to analyze the mobile device for possible security issues. It is based on the SafetyNet API, developed by Google, designed to check whether a device has been tampered with—whether it has been rooted by a user, is running a custom ROM, or has been infected with low-level malware.

How does it work?

The app first sends a request to the device to determine its model and serial number.
