Android-7.1-Nougat-Includes-Panic-Detection-Mode-900x440.jpg

Hello MIUI'ers,

While many readers of Android-centric websites such as our own are less likely to come across situations where a rogue application compromises their system, the same may not be true for the general population. Nearly every week we hear from various security researchers about new malware targeting Android users. Most of these malicious attacks can be avoided by inspecting permissions or avoiding installing sketchy-looking applications, and while we do recommend our readers take their phone’s security into their own hands, Google is responsible for securing every Android phone. To that end, the company quietly introduced a new security feature in Android 7.1 Nougat called “
panic detection” which listens for multiple back button presses in succession then returns the user to their home screen.

Quite simply, if a rogue applications attempts to hijack the user’s screen and prevent the user from leaving (perhaps by implementing an Accessibility Service to intercept all key events), Android will itself override the application to bring back the home screen. The user can then presumably uninstall the malicious application from the launcher.

This feature flew under the radar, understandably so as Google would likely not want to advertise to the world one way they are gutting malicious applications. But a quick look at Android’s open source code reveals how this simple feature works on the devices that support it.
