Google Pilots Android In-Call Warnings to Thwart Screen‑Sharing Banking Scams

A staged pilot with participating banks uses a full-screen warning with a 30-second pause to disrupt screen-sharing scams.

Overview

  • The protection activates only when a call from an unsaved number overlaps with screen sharing as a participating banking or fintech app is opened.
  • Android presents a full-screen alert that advises caution and offers an “End call now” button to terminate the call and stop sharing with one tap.
  • A mandatory 30-second pause follows the warning to interrupt high-pressure tactics and give users time to reconsider risky actions.
  • The pilot targets Android 11 and newer devices in select regions, expanding from earlier U.K. testing to U.S. trials with partners reported to include JPMorgan Chase and Cash App.
  • Google positions the feature as part of its AI-driven anti-scam effort, with availability limited during the pilot to participating apps and geographies.
