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
