Android Can Now Warn You When an AI Scammer Is Pretending to Be a Family Member

Google is expanding its anti-scam protections for Android with the launch of fake call detection, a new feature in Phone by Google designed to identify spoofed calls that impersonate people in a user’s contacts. The feature, rolling out globally this month to Android 12 and newer devices starting with Pixel phones, aims to help users spot increasingly sophisticated scams that combine caller ID spoofing with AI-generated voice cloning.

The company said fake call detection works when both parties are using Phone by Google. During a call, the devices exchange a silent verification signal using end-to-end encrypted Rich Communication Services (RCS) technology to confirm that the call is originating from the contact’s actual device. If that verification cannot be completed and the contact’s device confirms it is not placing a call, Android displays a warning advising the recipient to hang up.

Google is positioning the feature as a response to a growing wave of impersonation fraud, where scammers disguise their phone numbers to appear as trusted contacts and use AI-generated voices to mimic family members, employers, or authority figures. According to Google’s announcement, impersonation fraud was identified by INTERPOL’s March 2026 Global Financial Fraud Threat Assessment as a major contributor to more than $400 billion in global losses. The company also noted that impersonation scams remain among the most frequently reported fraud categories tracked by the U.S. Federal Trade Commission.

The launch builds on Google’s broader efforts to combat scams across its products. Earlier protections include verified financial calls, which alert users when callers falsely claim to represent financial institutions. Google also offers AI-powered scam detection in Google Messages, optional scam call detection in Phone by Google for Pixel and Samsung devices, business sender verification through RCS for Business, and support for STIR/SHAKEN call authentication standards in multiple countries.

Google said the new protection is enabled by default and can be turned off through Phone by Google settings. Because the system is built on the RCS standard, the company said the underlying technology could also be adopted by other apps and device manufacturers.

The introduction of fake call detection reflects the growing challenge posed by AI-powered impersonation scams. As voice-cloning tools become more accessible and convincing, technology companies are increasingly adding verification and authentication layers designed to help users confirm who is actually on the other end of a call before sensitive information or money changes hands.
