Following multiple developer previews and beta releases, the final release of Android 12 for Android TV/Google TV is finally here. Although this is the final version, it’s still aimed at developers. That means you can’t just download it on your Chromebox or an Android TV streaming stick.
To try out Android 12 for Android TV, you’ll need a device called ADT-3, an Android TV dongle for developers. The public for Chromecast with Google TV and other compatible Android TV devices will likely arrive in early 2022.
With the official release of Android 12, we are also making the most recent platform release available for TV. Take this opportunity to start building and testing your apps to make it compatible with the latest Android release on the new Google TV experience

It brings a redesigned UI with support for 4K UI rendering, dynamic refresh rate switching, background blurs, improved support for HDR formats and surround sound formats, Android 12-style microphone and camera indicators for enhanced privacy, and much more.

Google says those with an existing ADT-3 developer device will automatically receive an OTA to Android TV 12. If you haven’t received the update yet, you can also update your device manually by flashing the system image on your test device.
Android TV 12 comes about a month after Google officially released Android 12. The update has so far rolled out to the Pixel phones and Samsung’s Galaxy S21 series, with more smartphones to follow suit in the coming months.
