Google continues rolling out its Fuchsia operating system for this device
The second generation Google Nest Hub smart display is getting updated to Fuchsia OS
Since you might not be able to see much of a difference between the Fuchsia OS experience and the original Cast OS, you can find out if your Nest Hub has been updated by going to the “Technical Information” page in Settings to see whether it mentions a “Fuschia version.” If it does, that means your smart display has been updated and is running on Google’s Fuschia operating system.
With the upcoming introduction of the Pixel Tablet, the Nest Hub smart speakers are going to lose Google Assistant-powered apps and games later this year. Google has also stopped offering updates for third-party smart displays. Ironically, while Fuchsia looks similar to Cast OS, there is one thing that it does faster than its predecessor and that is casting content.
