If you are interested in installing APK Files and App from unknown sources, you need to enable the option to Install Apps from unknown sources on your Android Phone.
Install Apps From Unknown Sources
By default, most Android Phones allow installation of Apps only from Google Play Store and give a warning or error message when you try to install Apps from other sources.
The warning message reading “For your security, your phone is not allowed to install unknown apps from this store” is designed to discourage users from installing Apps from untrusted sources.
While it is safer to stick to apps from Google Play Store, there will always be a need to install Apps or APK Files from other trusted sources.
For example, if you are looking to install WhatsApp on Android tablet, you need to download an APK File directly from WhatsApp.
Since, WhatsApp is a known website, you can safely enable the option to Install Apps from Unknown sources on your device.
