Galaxy S8 And S8 Plus: How To Activate Unknown Source

If you’ve recently bumped into the topic of activating unknown sources on your smartphone, you probably have some questions. To begin with, an unknown source is any other source than the Google Play Store. The Play Store might have been the only place where you used to go and search for third-party apps to install on the Samsung Galaxy S8 or Galaxy S8+ Plus. But at some point, you might want or need to install an app from a different source.


Your smartphone is set, by default, to block any attempt of downloading apps from unknown sources. The way you can skip this issue is by learning how to activate the Unknown Sources option on the smartphone. Once you do that, you will be able to head to third-party app stores such as Amazon App Store and many others. But how do you get there, first?

  1. Go to the Home Screen of your smartphone;
  2. Open up the apps menu;
  3. Go to Settings, at Device Security;
  4. Find the Unknown Sources option;
  5. Select it and make sure that its toggle switches from Off to On.


The moment you turn On the Unknown Sources and leave the settings, you can install whatever apps you want, from whatever sources other than the Google Play Store.

As you can see, there’s no secret on how to lift up this interdiction. But you should still consider the danger you’re exposing yourself if you leave this feature active permanently. To avoid getting infected with malicious apps, make sure that after you activate Unknown Sources on Samsung Galaxy S8 and Galaxy S8+ Plus and install the desired apps, you also deactivate it back.
