Step 1. Enable APK installs on your device

Before downloading APK files through Chrome or other browsers, we have to ensure that our Android phone settings are enabled to install third-party apps downloaded from the Internet. 

Go to Settings, tap Password & Security → Privacy → Special app access, and then tap Install unknown apps. 

Step 2: In other versions of the Android system, you can go to Settings, tap Apps & Notifications, then tap the Special app access, and you will find Install unknown apps entrance

On the Install unknown apps page, find your preferred browsers that you want to use to download the APK files. Click them and then enable the toggle button so that the apps downloaded through this source can be installed on your device.

Step 3: Download & Install 

Use your preferred browser to download the APK file. When download completes, you can either go to the Download folder of the browser or the File Management of your device to find the APK file.
