How to allow apps installation from unknown sources on Android 9 Pie

Installing APK files on Android devices has been pretty easy since the beginning and users simply had to unlock the developer options and turn on the Unknown Sources option.

However, in order to make Android devices more secure and avoid apps from installing malware on the device, Google removed the unknown sources option.

The move was made to ensure apps do not automatically install unwanted apps and malware on Android devices; however, if you simply want to sideload an APK file to your device, then here’s the new way to install apps from ‘unknown sources’ on Android Pie.

The process is fairly easy and you should get used to it within no time. So let’s check out how to install apps from unknown sources.

  3. Now tap on the 3-dots icon located at the top right of the screen.
  4. Select Special access. 
  5. Tap on install unknown apps.
