You need to grant the "Install unknown apps" permission for the specific app you'll use to open the APK file (this is usually your File Manager app or the Browser app you used for the download).Find that app in your settings and toggle the switch for "Allow from this source" to ON.(Older Android versions might have a single, global "Unknown sources" setting.
