Besides the official store Google Play on your phone, I'm sure that sometimes you need to sideload other applications from outside sources. For example, to download apps isn't available on Google Play or geo-restricted apps, etc. As you may know, Android OS is an open-source that enables its users to access third-party app installations, provided that you activate the security settings "Unknown Sources" on your Android phone. Some Android users may find it a bit confused about how to enable this function since it's quite different between Android Oreo and Android nougat. More importantly, you also keep in mind that opting for a safe and reliable source before sideloading apps is a must to avoid the risk of getting attacked by malware and viruses from untrustworthy sites. So here are the steps to grant third-party permissions:

If you have a phone running Android 7.0 Nougat or lower, enable Unknown Sources is much easier since all you need to do is navigate to Settings>tap Security> click the Unknown sources, switch to turn on or off. Plus, you only need to enable "Unknown Sources" once for allowing every external app's installation.

If you're using Android 8.0 Oreo or higher device, you can't find the allowance for third-party installations from Unknown Sources on the settings anymore because the tougher permission is tied to the app itself, not any users settings. To turn Unknown Sources on, here are the steps:
1. Open the device Settings
2. Then, tap on Apps and Notifications
3. Select Advanced>scroll down and find Special App Access> tap Install Unknown Apps.
4. Choose the app that you want to enable> Switch on "Allow from this source".

Hope this helps. (lightbulb)

Thanks a lot. Finally I know the reason why I can't enable Unknown Source because now I'm using Android Oreo and it doesn't show in the security settings when I search. Really have no idea that Google has removed this option in Android Oreo phone.
