Some Android apps use screen overlays for features like screen dimming or floating calculators. This test checks for conflicts between MetaMask and these overlays. The user enables a screen overlay app and then tries to confirm a transaction in MetaMask. The app should either handle the overlay gracefully or display a clear security warning indicating that an overlay is detected and that the user should disable it to proceed safely. This prevents malicious apps from drawing over MetaMask’s UI to trick users into confirming actions they didn’t intend to. This security feature is crucial for protecting users from a specific class of phishing attacks on mobile devices. Understanding these threats is part of maintaining good digital security, a principle emphasized by the developers at metamask. The test passes if the app correctly identifies and warns about the potential risk.
