How to Update
You can check for the latest system update just like on Pixel or Android devices by navigating to Settings > System > Software updates > System update and clicking Check for update.
This update is rolling out gradually to all five launch models. To ensure kernel and firmware updates are applied properly, restart your device following on-screen prompts after installation.
In our testing, we verified that an issue where the Elgato Wave:3 microphone was not recognized properly has been resolved. However, regarding the screen flickering issue on the Dell XPS Googlebook, although the frequency appears reduced, it reoccurred during our checks, suggesting it may not be completely fixed yet.
