Although this is the final version, it is still aimed at developers. This simply means that ordinary users cannot download it on Chromebox or Android TV. They need a device called ADT-3, which is an Android TV adapter for developers.

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 them compatible with the latest Android release on the new Google TV experience. Alternatively, the build images for the standard Android TV experience are also available for download.

We have added further customizations in Android 12 to improve the experience and compatibility on TV devices. Some of the highlights coming with Android 12 for TV are media playback improvements, more refined user interface capabilities, and privacy and security enhancements. In addition, we are introducing better standards support and improvements for HDMI and tuners.

Google said that existing ADT-3 developer devices will automatically receive Android TV 12 updates over the air. If not, click here to download the mirror manually and flash in.

However, we still have no hint when this update will come to the Google Chromecast dongle. As a reminder, it is still running Android TV OS 10 and hasn’t seen any updates in a few months.
