It's been about a month since Android 12 started coming to Pixel phones, timed perfectly with the launch of Google's newest hardware. Since then, Samsung has already managed to get its own update out the door for the S21 series, potentially making it one of the widest launches for a new OS version yet. If you're an Android TV user waiting impatiently for an update to your streaming device, it might not be far off, as Android 12 is finally available for developers.

Just as with this past summer's beta, you won't be installing it on your Chromecast or Shield TV any time soon. You'll need an ADT-3 — Google's development box for the platform — to get it up and running today. The rest of us will have to wait for an official update, hopefully coming sometime in the near future.

As for what awaits you once the update is out and active, there are a few key changes to keep an eye on. The UI is getting a tune-up, complete with 4K support, new background blurs, and text scaling under accessibility. The privacy indicators from Android 12 on smartphones are making their way to TVs, displaying on-screen when any connected mics or cameras are active. Google is also including support for HDMI CEC 2.0 and reducing motion judder while playing back files with refresh rate switching.
