How to Install Apps from Unknown Sources on Android

Unknown Sources Install Apps

One of the more sensible default security features on Android devices is not allowing users to install apps from outside the Play Store. But with plenty of great apps you can find outside the Play Store, you may want to venture beyond those walls every now and then. Luckily, it’s fairly easy to install apps from unknown sources on Android.

Do you know: Other than APK, there is another file type known as XAPK. Learn what is XAPK and how to install it on your Android device.

Change in Installation Method


Since Android 8.0, the method to install apps from unknown sources has changed. Instead of the previous method where you gave permission to download APKs through an existing app on your phone, the newer installation method requires you to give permission to specific apps that are allowed to install APKs from unknown sources. Let’s check the steps for different Android versions to grant this permission.

Good to know: Other than installing apps, you should also learn about uninstalling apps and getting rid of residual files on your Android phone.

Find APKs Outside Google Play Store

Once you’ve enabled unknown sources, it’s time to download the APKs you want. Maybe you already have a site you trust for downloading APKs. If not, we recommend APKMirror as a good place to find legal APKs of old versions of Play Store apps, free apps, and so on.


You can download APKs directly through the web browser on your phone, at which point you’ll receive a message stating, “This type of file can harm your computer.” Don’t worry, if you’re getting your file from APKMirror or another site you trust, then your phone’s perfectly safe.

Download the file, then open the APK from the pull-down notification menu on your phone or by browsing the “Downloads” folder on your phone’s file manager. Tap Install and your fancy new app should be ready shortly.

You can also download APKs through the browser on your PC, at which point you’ll need to transfer the file over to your phone via microUSB or wirelessly, and install from there.

Install Using Google Drive, Dropbox and Other Cloud Services

Alternatively, if you’re download the APK on a device other than your phone, you should be able to navigate to it on your device, then upload it to a cloud service such as Google Drive or Dropbox. Once you’ve done this, you can access it through Drive or Dropbox on your phone and open it directly from the cloud service, beginning the installation process.
