What are Unknown Sources on Android?

Unknown sources on Android refer to locations outside of the official Google Play Store from which you can download and install APK apps. While Google encourages users to obtain apps exclusively from the Play Store for security reasons, there are scenarios where you may need to source apps from other places. For instance, beta versions or apps from third-party markets may require this permission. This process of installing apps from non-Play Store sources is often referred to as “sideloading.” Since the early iterations of the Android OS, users have been required to explicitly enable this setting to allow the installation of apps from unknown sources. Attempting to install an APK without this setting enabled triggers a prompt message.

“For your security, your phone is not allowed to install unknown apps from this source.”


How to Enable Unknown Sources on Android?

Downloading apps that are not available on the Google Play Store is possible by enabling “Install Unknown Apps” on your Android device. However, due to the iteration of Android system versions, the method for enabling unknown sources may vary. Please refer to and follow the navigation below based on your device version.

  1. Go to your Android Settings > Security.
  2. Check the option Unknown sources.
  3. Tap OK on the prompt message.
  4. Select Trust.

For Android 9.0 and later versions, it’s essential to enable Unknown Sources individually for each app that intends to install an APK file. For instance, if you have both Chrome and Firefox browsers installed, you must grant permission for both Chrome and Firefox to install apps from unknown sources.

For New Android Versions (Oreo, Pie, Android 10, 11, and 12)

  1. Go to your Android Settings > Apps & Notifications.
  2. Select Advanced or the three dots at the top-right corner – users might see either option depending on their device.
  3. Select Special App Access.
  4. Choose to Install Unknown Apps.
