What is unknown source?
Enable Unknown Sources. To install app stores that are not initially present on your device, Android requires you to enable the Unknown Sources setting. This allows you to download apps and games from sources other than Google to your mobile device.
Is it safe to install apps from unknown sources?
Avoid unknown sources. You have the option of installing Android apps and games from sources other than Google Play (sometimes known as sideloading). The problem is that many third-party app stores are not safe. If you choose to download an APK file and install it yourself, you could be putting malware on your device.
