Android 13 Beta for TV has been released, giving us our first glimpse of the next generation of Android TV.
The first beta version of Android 13 TV's user interface is currently available for developers and power users to preview.
However, you cannot update your current Android TV/Google TV device to the latest beta release.
The Android 13 TV doesn't look much different from the Android 12 TV in terms of visual upgrades.
However, as Mishaal Rahman points out, there is no support for enlarged picture-in-picture mode or Fast Pair in the first beta.
