Signature Spoofing Checker

Test the signature spoofing capability of your OS

This app tests the signature spoofing capability of your Android OS as required by the microG Project. It attempts to fake its own signature and reports whether it succeeds. Simply launch the app to see the result of the test. You can find more information about signature spoofing here.
