How to: Allow apps installation from unknown sources

Installing APK files on Android devices is really easy and users simply have to unlock the developer options and turn on the Unknown Sources option.

However, to strengthen the security of android devices and avoiding apps from installing malware on the device, Google has removed the unknown sources option.

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

The steps are very easy to follow and you can get used to it in no time. So here’s how to install apps from unknown sources.

Remember that this only works on devices running Android Pie and Android Oreo.


Step 1: Open the Settings app on your device.

Step 2: Select Apps & notifications.


Step 3: Choose Special access under the Advance option.
