Google adds new scam guard to Android Messages
The new protection mode uses cloud and on-device AI to filter spam, with specific hardware requirements for link analysis.

Google is expanding its spam defenses in the Android Messages app by rolling out a new protection tier called Enhanced Protection. The feature is now available in the latest beta version of the application, which carries the build number 20261020_00_RC00. This update adds a higher level of security for users dealing with unknown senders and suspicious links.
The new mode builds on the existing Standard Protection, which already blocks known spam and harmful links. Enhanced Protection introduces three distinct capabilities aimed at catching more sophisticated attacks. The first is a new scam detection system that analyzes the context of a conversation to identify fraudulent intent. This tool is particularly useful when a user is messaging a number not saved in their contacts.
To power this detection, Google utilizes cloud-based Gemini models. These models assess the broader context of a message thread to determine if a sender is likely a scammer. Google states that this cloud-based approach handles novel and complex attacks more effectively than the detection methods currently running directly on the device.
Privacy concerns regarding cloud processing are addressed through Android's Private AI Compute system. When this feature is active, messages are encrypted and processed in a secure environment. Google describes this space as private to the user, meaning the data is not accessible to anyone else, including Google itself, during the analysis process.
The second component is enhanced link protection. This feature combines the on-device Gemini Nano model with real-time web signals to evaluate the safety of unfamiliar links. It aims to determine whether a link is trustworthy before the user taps it. This specific capability is not available on all devices. It supports the Pixel 10 and newer models, the Samsung Galaxy S26 series, the Galaxy Z Flip 8, and the Galaxy Z Fold 8, along with other select devices.
The third change involves a redesign of the warning system. When a link is sent from a number that is not in the user's contacts, the app now displays alerts that provide more context. These redesigned warnings are intended to give users additional time to pause and consider the message before interacting with the link.
Enhanced Protection is an opt-in feature. Users can activate it by navigating to the settings in Google Messages and selecting Protection and safety. The menu now offers three choices instead of a simple toggle. These options are Enhanced protection, Standard protection, and No protection. The app labels the No protection setting as not recommended.
The rollout follows an announcement made by Google earlier this month. The feature is currently visible in the beta channel, indicating a phased release to the wider user base. Users on supported hardware can now check their settings to see if the new option is available on their specific device.
