1. Enabling APK Installation

When you have downloaded APK files outside of Google Play Store, please be aware that your phone is authorized to support installing third party applications.

By default, android devices do not allow third party apps installation, only those apk files that are sourced from Google Play Store are permissible.

Fortunately, you can solve this issue with the following steps:

For Android system earlier than 8:

Open Settings app on phone, tap on Security to toggle ‘Unknown sources’ option on.

For Android 8 or above:

1. Samsung Devices: Scroll to find Settings app on phone. Tap on ‘Security & privacy’ > ‘More settings’ > ‘Install apps from external sources’ option, then you’re free to select one desired browser, then turn 'Allow app installs‘ option on.
2. Other Device: Go to Settings app on phone. Tap ‘Biometrics and security’ > ‘Install unknown apps’, then choose one browser that you would like to download apk files from, then turn ‘Allow app installs‘ option on.

2. Manually install the App from APK

Connect your Android to computer via USB cable, Tap the USB connection notification that shows on your Android screen. Choose Transfer File.

Find the apk file that you wish to download from the computer, right-click on this apk file icon and click on “Send to“ > “Your device name“. Wait for complete.

Now, unlock your Android phone, navigate to the File Manager app (maybe some are File/File Explorer), find the apk file you downloaded just now. If there is an external SD card in your Android phone, the files might be saved in External Storage.

Run this apk file on your phone, choose Next when you see a pop-up prompt, just tap Done button to finish the installation.

If you prefer a better way to organize your apps, you can use third party versatile software to install APK on Android.

This is where third party software comes in handy. They’ve got a reliable package manager for you to install apps easily and safely.
