Android expands in-call scam warnings as screen-sharing fraud rises in the U.S.

Google is broadening Android’s in-call scam protection system to users in the United States, aiming to curb a growing wave of fraud attempts involving screen-sharing during phone calls. The feature, previously piloted in the U.K. and later tested in India and Brazil, is now being deployed more widely through partnerships with U.S. financial institutions and peer-to-peer payment services.

The tool is designed to detect situations where a user, while on a call with an unsaved number, attempts to open a banking or financial app. Android will halt the action, display a warning, and introduce a mandatory 30-second pause before the user can continue. The system also offers an immediate option to end the call or stop screen-sharing.

Google says scammers increasingly convince victims to share their screens to access bank accounts, conduct unauthorized transfers, or gather sensitive information. The company points to more sophisticated social-engineering techniques—often involving impersonation of banks or trusted institutions—as a key factor behind the feature’s expansion.

In the U.S., the protections are rolling out initially with support for banking apps such as JPMorgan Chase and payment platforms including Cash App. Android users on version 11 or later will begin seeing the alerts as the pilot scales up.

The U.K. launch earlier this year has already resulted in thousands of users ending potentially fraudulent calls, according to Google. That early data prompted Google to expand the program to more app categories internationally and, now, to the U.S. market.

While the system focuses on preventing financial exposure during active calls, it also reflects a broader effort by Google to deploy AI-driven tools across Android to counter scams in voice calls, SMS messages, and app notifications. The company says it intends to extend the protections to additional financial services as the pilot continues.
