Android's AI Scam Defense
Google launches new fake call detection on Android to combat AI deepfake scams
Anonymous
Google is rolling out “fake call detection” in its Phone by Google app to Android 12+ devices worldwide, starting with Pixel phones, to counter AI deepfake impersonation scams. The feature is enabled by default and uses an end-to-end encrypted RCS “silent confirmation signal” between the real contact’s device and the caller’s device; if the signal is missing because a scammer spoofed the contact number, Android flags the call and prompts the user to hang up. Google and others warn that spammers increasingly rely on AI voice-cloning and trusted-number spoofing to bypass older spam defenses, citing large losses to AI-enabled scams. Alongside the safety update, Google is adding AI and personalization features across Android apps, including Google Photos “wardrobe” for cataloging and virtually trying on outfits, Circle to Search improvements to identify entire outfits from images, and an AI recap feature in Google Play Books. The company is also expanding Personal Safety access by allowing children under 13 to display emergency and medical information on lock screens and enable safety tools such as car crash detection.
Key Points
1
Google and coverage tied the feature to specific reported losses: The Verge noted the FBI reported Americans lost “over $893 million” to AI-enabled scams in 2025, underscoring why impersonation defenses are urgent.
2
In a Wired demo, the reporter heard their own public voice used in an impersonation attempt and received an on-screen overlay: “This may not be Lily. Someone may be pretending to call from your contact's number.” Wired also quoted Google security/privacy leaders Dave Kleidermacher (Android’s VP of security and privacy) and Eugene Liderman (director of Android security and privacy product) describing a “real desire” to push defenses forward for victims.
3
Google emphasized ecosystem adoption: TechCrunch reported Google built fake call detection “on top of Rich Communication Services (RCS), making it possible for other apps and companies to adopt the technology.”
4
The feature has a concrete prerequisite: The Verge reported it “only works if you and a trusted contact both use Phone by Google,” because the trusted contact’s device must send the “silent confirmation signal” that verifies the caller’s identity.
