Google New Feature Drop Includes Spam Text Alerts, Pulse Loss Detection

Google’s new batch of Android features announced Tuesday include scam detection for its Messages app and, for Pixel Watch 3 owners, a pulse loss detection feature that will automatically call emergency services.

Google’s Scam Detection feature will use on-device AI to analyze conversations for suspicious patterns, and will display an on-screen prompt when the feature believes you are having a conversation with a scammer. That prompt will also provide access to either dismiss the message, or report and block the sender. This feature will be turned on by default, with Google noting that all AI processing remains on the device. It can however be turned off at anytime.

This feature arrives alongside the similar Scam Detection feature in Google’s Phone app that was first announced at Google I/O 2024, which sends a prompt when it detects that you might be on a call with a suspected scammer.

Meanwhile for Pixel Watch 3 owners, that device’s new Loss of Pulse Detection feature is launching in the US after receiving clearance from the US FDA last week. Google says the feature will arrive to watches at the end of March, and will activate in events that cause loss of pulse such as cardiac arrest or circulatory failure. This feature is already in 14 countries including the European Union.

Google’s announcements arrive amid Mobile World Congress 2025, during which the company is also showing off new Gemini AI features where the assistant can respond to questions based on what your camera sees or through screenshare.
