Google is rolling out an optional enhanced-protection mode in Messages over several weeks, using Gemini and Private AI Compute to analyze complex scam context from unfamiliar senders. Supported devices also use an on-device model to check suspicious links. Google is reducing exposure of sensitive information during screen sharing in Chrome and WebView on Android 15 and later, and plans to block background call forwarding on some Pixel and other devices from early December. The company says cloud processing uses an encrypted protected environment. Not every protection is immediately available on every Android device.
