How to Enable 'Unknown Sources' on Android to Sideload Apps

Enabling 'Unknown Sources' on Android

The exact names of the settings entries listed below may vary slightly from device to device, but the overall process should be very similar. To begin, head to your phone's main settings menu, then look for an entry titled either "Security" or "Lock screen and security."

From this menu, simply tick the box or toggle the switch next to the "Unknown sources" entry, then press "OK" on the popup.

After that, you're all set up and ready to go. From now on, you can simply open any APK installer file to install any third-party app of your choosing.
