# Enhanced protection mode in Google Messages

Android is rolling out a set of new scam defenses: an Enhanced protection mode in Google Messages that uses cloud Gemini models to judge an unknown sender's intent, on-device Gemini Nano that weighs real-time web signals to decide whether an unfamiliar link is trustworthy, and a real-time check with banking apps that hangs up and warns users about calls failing to verify as bank-initiated. Previously these protections were limited to select devices, select countries, or devices with Android Advanced Protection enabled, and chat notification scam alerts covered only Pixel. Google says that since launching in June, more than 3 million spoofed calls from Banco do Brasil and Itaú Unibanco alone have been blocked.
