It uses the latest version of Android TV, 8.1, with a new interface allowing more customization. The Google Assistant is built-in, allowing voice commands with the included Bluetooth remote. There's a quad-core CPU, and like other Android TV devices it has Chromecast built-in too. > Android TV has plenty of apps -- more than 3,000 total -- and the Mi Box S includes Netflix, Vudu, YouTube and SlingTV, for example. On the other hand the Mi Box S doesn't have Amazon Prime Video, which is available on all of its competitors as well as the Nvidia Shield.
