RTD1395 4K TV BoxDune HD RealBox 4K runs two operating systems simultaneously: Linux-based Dune HD OS and Android 7.1 with the former aiming to ensure “stable operation and smooth media playback”, and the latter to allow running Android apps. That means you’d actually use a Linux device while playing videos within Dune HD UI, but it would act like a standard Android OS TV box for other apps like web browsers or games.

The device also supports Smart Home and Home Automation integration with systems such as Control4 and Creston. Dune Control mobile app for Android and iOS allows you to easily access your video library and control the media player with your mobile phone.
