Google launches fake call detection on Android to warn users when scammers impersonate trusted contacts using AI deepfake voices

Google announced fake call detection rolling out globally to Phone by Google on Android 12+ devices this month, starting with Pixel devices. The feature works by default and automatically verifies calls between users of Phone by Google through a silent confirmation signal between devices.

When a scammer tries to impersonate a trusted contact, the confirmation signal is missing. The device detects this and pings the actual contact's device to double-check; if their device reports no outgoing call, the user receives a warning to hang up immediately.

The feature is built on top of Rich Communication Services (RCS), enabling other apps and companies to adopt the technology.

Google also announced updates to Google Photos (new virtual outfit try-on rolling out next week in the U.S., India, and Brazil on Android 10+), Google Play Books (new "Catch me up" recap feature rolling out today for select English titles), and Circle to Search (now able to search entire outfits at once on Android 14+ devices).
