Call Screen is the smart call-answering feature of the “Phone by Google” app, the default phone app on Google Pixel devices. In some regions, such as the U.S., it has adopted the Google AI model “Gemini Nano” and is rolling out Gemini-based smart reply suggestion features.

Gemini Nano for the “Phone by Google” app’s “Call Screen” was announced as part of the “Pixel Drop” new feature release for Google Pixel devices in December 2024. It initially began rolling out for the English language environment on the “Pixel 9,” “Pixel 9 Pro,” “Pixel 9 Pro XL,” and “Pixel 9 Pro Fold.” It should now also be available on the new generation of Google Pixel devices: the “Pixel 10,” “Pixel 10 Pro,” “Pixel 10 Pro XL,” and “Pixel 10 Pro Fold.”

Additionally, from the in-app code of the “Phone by Google” app v199 (v199.0.826490146-publicbeta) update, released on Friday, November 7, 2025, it has been confirmed that strings hinting at an expanded rollout of “Gemini Nano” in “Call Screen” have been added.
