With Android 7.1, Google has added a so-called “panic button”” behavior in its mobile operating system. Users can immediately shut down any app they suspect of being infected with malware. Android interprets these four quick and successive Back button presses as the user panicking about an app and wanting to close it before it does something malicious. The backPanicBehavior is currently disabled and appears to be under testing. It is unclear if the feature has been fully implemented yet
