First, download the RS9 APK file. Once the file is available on your device, open your Downloads folder and select the APK.
If Android asks for permission to install applications from unknown sources, review the source carefully and enable the required permission only when you trust the application source.
After installation is complete, open the RS9 app and continue with the available setup process.
