Block the app after installation by Google Protect

Question

When installing an application on Android 7, Google's protection system prevents it from installing and displays the following message:

Play Protect doesn't recognise this app's developer. Apps from unknown developers can sometimes be unsafe.

How can i fix it?

Answer 2

Yes, it's usually caused by an APK manually installed without downloading it from PlayStore. The Protect informs the user about the potential problems about installing this kind of App. You can disable the Protect from Android Settings page or (maybe) room the PlayStore Settings.
