Turns out the answer is yes, although some of the new Android TV 14 tricks won’t work on every device. For example, the Thread border router functionality requires a Thread radio, which is not present in most existing devices. Even if these devices receive the Android 14 for TV update, they won’t be able to act as Thread border routers.
They specifically mentioned that this would be the case for the Chromecast with Google TV. Even though it’s getting the Android 14 upgrade, it won’t be able to use the Thread features like the new Google TV Streamer can because it simply doesn’t have the necessary parts inside.
Google giving the Chromecast with Google TV the Android 14 treatment isn’t a huge surprise. They promised to keep providing software and security updates even when they announced they were phasing out the Chromecast brand. In fact, the Chromecast with Google TV (4K) is supposed to get security updates until the end of September 2025, while the Chromecast with Google TV (HD) is covered until the end of September 2027.
The original Chromecast with Google TV (4K) came with Android TV 10 and later got updated to Android TV 12. The HD model started with Android TV 12 right out of the box. So, Android TV 14 would be the second major OS upgrade for the 4K model and the first for the HD model. This continued support for the Chromecast with Google TV ensures that users can continue to enjoy their devices for years to come.
