In Android, found a hidden “panic mode” to combat the virus



Android users regularly find themselves in danger due to different malicious applications. There are several types of viruses: some steal personal information, including information on Bank cards, others send premium SMS, third download in the background other applications to cheat the ratings, etc. Quite unexpectedly, the developers of the popular website XDA have found that in the latest versions of Android, Google added a hidden “panic mode” of anti-malware applications.

A new feature called “Discovery panic.” Interestingly, the company itself never officially her were not and have never mentioned it. This option monitors how the user presses the system “Back” button. Mode “panic” is activated if you press this button at least four times in a row with a delay of no more than 300 MS. The fact that Android code is written, that the system reserves the period of delay at 300 MS after pressing the button “Back” for deciding if the user wants to return to the previous page or the start signal “panic mode”.

If the user has launched this “panic mode” multiple quick taps of the Back button, the system understands it and determines what application is currently running, it blocks and returns the user to the main screen, so that he could remove the malware.

It is important to note that this feature only works with Android 7.1 and later versions. However, even the presence of the desired firmware does not guarantee that the option is enabled on the device. You can check this in the file config.xml in SystemUI APK.
