How does the enhanced protection mode analyze messages?

It uses cloud-based Gemini AI models to evaluate a potential scammer's intentions in conversations with an unrecognized sender, and on-device Gemini Nano AI to inspect real-time web signals in unfamiliar URLs before they're opened.

Is the enhanced protection mode required?

It is opt-in, meaning users must choose to enable it. User data is encrypted during the AI analysis and processed in a secure dedicated space that Google cannot access.

Which devices will get the expanded scam detection?

The chat notification scam detection is expanding to devices from Honor, Motorola, Oppo, OnePlus, Realme, Tecno, Vivo, Xiaomi, and more, with Google planning to bring it to hundreds of millions of additional users later this year.

Context & Analysis

Google's new features build on the Scam Detection feature it introduced in Google Messages and on Pixel phones last year. By adding a cloud-based Gemini AI layer alongside existing on-device detection, Google says it can catch novel and sophisticated attacks that hide behind slow-burn conversations. The company is also addressing other fraud vectors: it will block apps from enabling call forwarding and notify users when someone tries, and it will automatically conceal sensitive information while screen-sharing in Chrome and Android WebView. The expansion of chat notification scam detection to brands including Honor, Motorola, Oppo, OnePlus, Realme, Tecno, Vivo, and Xiaomi suggests Google is pushing these protections beyond its own Pixel devices. The opt-in nature of enhanced protection and the encryption of user data during analysis may be aimed at addressing privacy concerns that come with cloud-based scanning of personal messages.
