Google Messages Adds Opt-In Cloud AI for Scam Checks

400 million Android users can now activate a new layer of security in the Google Messages app. This Enhanced Protection mode is currently rolling out to the latest beta version, 20261020_00_RC00. It sits above the existing Standard Protection that blocks spam and harmful links.

The update relies on cloud-based Gemini models to analyze message threads from unknown senders. Google states this method identifies scam intent faster than on-device detection, particularly for novel attacks. To maintain privacy, the system uses Android's Private AI Compute. Messages are encrypted and processed in a secure space that Google describes as private to the user, meaning even Google cannot access the data.

A second feature combines the on-device Gemini Nano model with real-time web signals to vet unfamiliar links before a user taps them. This specific capability is available on the Pixel 10 and newer, the Samsung Galaxy S26 series, and the Galaxy Z Flip 8 and Z Fold 8.

The app also redesigns warnings for links from unsaved numbers. These new alerts provide more context and time for users to pause before interacting. Enhanced Protection is strictly opt-in. Users access it through the Protection & safety settings menu, which now lists three distinct choices.

The menu presents Enhanced protection, Standard protection, and No protection. The app labels the final option as not recommended. This structure allows users to choose their level of intervention without a simple on/off toggle.
