google is launching a fake call detection feature on android to counter scams that use ai deepfake voices. the tool works automatically on android 12 and newer devices, starting with pixel phones. it checks if a call from a saved contact is real by sending a silent signal between devices running phone by google. if the signal is missing, the system pings the contact's actual device to confirm. a warning appears if the call is fake, telling the user to hang up.
the feature relies on rich communication services, so other apps and companies can adopt it. scammers often spoof trusted numbers and use ai to mimic voices of family or bosses, making calls seem urgent. this method adds a layer of verification without user effort. google also announced other updates, including a virtual try-on for outfits in google photos, a story recap tool in play books, and an expanded circle to search that finds whole outfits at once.
the call detection is on by default and runs in the background. it does not require extra steps from users. the approach uses device-to-device confirmation rather than analyzing voice patterns, which may avoid privacy concerns. the rollout is global, but initial availability focuses on pixel devices. the broader adoption of rcs could help standardize this protection across different phone makers and calling apps.
why it matters: it gives android users a passive defense against increasingly convincing ai voice scams without needing to screen calls manually.
