Google began rolling out a new Android feature designed to detect and flag spoofed calls, built into the Google Dialer and available for phones running Android 12 and later. When one Android user calls another, the device sends a “real-time, silent background confirmation signal” using the RCS standard to verify the call is genuinely coming from the contact's phone, and if that confirmation is missing, the Dialer warns the recipient with a pop-up, removes the contact photo, and logs the call as “Unknown caller.” Android security VP Dave Kleidermacher said the approach is meant to be higher-confidence than using AI to detect voice clones, which can produce false positives and feed an arms race with attackers. The feature targets the rise of impersonation scams that use AI voice-cloning to mimic acquaintances or family in real time. For it to fully work, it would need adoption across all devices, including Apple's iPhones; Apple did not comment on whether it plans anything similar.
