Disable Unknown Sources

Anattractive feature of Android OS is the ability to manually install apps directly from the internet in its raw “APK” file format. The feature is tucked away in the Developer options to sway users from openly using it since it poses a security risk by allowing installation of apps that haven’t gone through the scanning process set forth by the Google Play Store.

To disable unknown sources:

  • Go to Settings
  • Navigate to the System – Advanced tab and find the Developer options menu
  • Scroll down to find Unknown sources and disable it by pressing the toggle right next to it

With the added permissions, a risky app has the capability to install other malicious apps when the “Unknown Sources” feature is enabled, which is why turning it off is essential.
