Digibox D3 uses the Android 12 operating system. After testing, D3 provides three ways to install APP:

1. Use the built-in GOOGLE PLAY to download most apps, users can install the APPS programs they need as needed.

2. You can install it through APP STORE. As shown below, you can use the remote control to operate the process, which is very simple.

3. You can install the APP you need through the Aptoide TV software in the APP STORE.

4. If you want to install a mobile phone or tablet-type APPS, you need to download the APK file from other channels, and then use a USB disk to install it in the DigiBox box.

The box is an open system and does not limit you to install it in that way. As long as the main APPS are compatible, you can install and use it. If the APPS cannot be used after installation, it will be incompatible and cause an exception. It is recommended that you delete the relevant APPS and find other replacement APPS to install and test.
