This new mobile anti-fraud feature will instantly break scam calls the moment your banking app opens

Android is testing a new anti-fraud feature in the US. The tool is designed to stop scam calls that try to trick users into sharing their screens and opening bank apps.

When a user receives a call from an unknown number and has screen sharing on, opening a bank app triggers a full-screen warning. The warning fills most of the screen and ends the screen share immediately.  

A prominent red “End Call Now” button is shown, and users are alerted that the caller may be impersonating someone else. Users are advised not to follow instructions or share any banking information. This feature works on Android 11 and later.

Scammers often create a sense of panic to make users act fast. They may pose as bank staff or law enforcement agents, claiming that funds are at risk. By asking the user to share the screen, scammers can see every step and take direct actions to steal money.

The warning feature interrupts this process at the most critical moment. It also adds a 30-second pause to help users stay calm and avoid mistakes. In tests conducted in the UK earlier this year, Google reported that this feature helped thousands of users avoid potential losses.

This feature is in testing for now so it may have some down sides. There is no information on when it will roll out fully. 

Google is partnering with fintech apps like Cash App and banks such as JPMorgan Chase to test this feature in the US. If the pilot succeeds, the tool will be expanded to more users.

Android also limits high-risk actions during calls, such as disabling Google Play Protect or first-time sideloading, to further reduce scam risks. By acting before damage occurs, this feature represents a clear step toward safer mobile banking and stronger protection against social engineering scams.
