Google announced an opt-in Enhanced protection mode for Google Messages on October 14, 2026. The mode would add cloud-based Gemini analysis of complex conversations with unknown senders, alongside separate safeguards for unfamiliar links. Google said the mode would begin rolling out in the coming weeks. Google’s announcement describes a plan, not a completed rollout.
What Enhanced protection would add
Google says cloud Gemini would assess message context in conversations with unknown senders, adding to Google Messages’ existing on-device scam detection. The idea is to look at a longer conversation, rather than just an individual message, when judging whether a scammer may be building trust over time.
Enhanced protection would also enable redesigned checkpoints for links sent from numbers that aren’t saved in a user’s contacts. Google lists Android 6+ for this checkpoint feature and says it had previously been limited to select countries or devices with Android Advanced Protection.
Gemini Nano checks links on the device
The link checkpoints are separate from Gemini Nano’s link checks. Google says the on-device model would use real-time web signals to assess an unfamiliar link before a user taps it. The company lists Pixel 10+, Samsung Galaxy S26 series, Galaxy Z Flip, Galaxy Z Fold8 and other select devices for this Nano feature. That list applies to link checks; Google announced the cloud-based mode separately.
What Google says about message data
Google says the cloud analysis would run in Private AI Compute, with encrypted data processed in a dedicated environment inaccessible to Google and others. Reporting a message as spam is a different action: Google says that when a user chooses to report one, the message and its contents are sent to Google for analysis.
Google also says its AI-powered Scam Detection in Phone by Google and Google Messages flags more than 5 million suspected scam calls and texts per month combined. That company-reported figure covers the two products together, not Enhanced protection alone.
Other Android protections announced alongside it
Google described several separate Android safeguards. A screen-sharing feature blanks login fields and payment screens in Chrome and Android WebView; Google said it was rolling out to Android 15+ devices. Call-forwarding protection would block apps from quietly enabling forwarding and warn users before a manually entered MMI forwarding code takes effect. Google said availability would begin in early December on Pixel and select devices.
Google also said Scam Detection in chat notifications, which launched on Pixel, was expanding to devices from HONOR, Infinix, iQOO, itel, JOVI, Motorola, OPPO, OnePlus, realme, TECNO, vivo and Xiaomi, among others. Availability varies by manufacturer.
