NVIDIA has released SHIELD Experience 9, a new UI for its TV sticks and boxes based on Android 11. The upgrade involves a bevy of new features, support for aptX-compatible Bluetooth devices, Dolby Vision HDR and the latest Google entertainment apps included. Some users can even unlock a trial of Peacock Premium.

I find it odd that Android for TV has better software support than Android for smartphones. Only Fairphone dares enough to do the latter.
