It has to be turned on, and it is still weeks out
The Verge reported on October 14 that Android is adding an enhanced-protection setting on top of scam detection already in Google Messages. The story time is 16:00 UTC, midnight in Beijing on October 15. The setting rolls out in the coming weeks. It calls cloud Gemini to judge what an unrecognized sender is trying to do. The setting is opt-in. It is not on by default.
Google's update says scammers often hide the real motive inside a long conversation. The cloud pass sits on top of the existing on-device check and is meant to catch attacks the on-device check has not seen. This piece does not repeat those attacks.

Google says it cannot enter the cloud step
The report says user data is encrypted during the analysis and processed in a dedicated space that Google, and anyone other than the user, cannot access. That is Google's account. This piece has no separate audit.
Enhanced protection also uses on-device Gemini Nano to look at live web signals in an unfamiliar link before the user opens it, and to judge whether the link is malicious. The pre-open check is the link, not a second use of the whole chat.

Also announced the same day: block apps from turning on call forwarding, and tell the user when someone tries; while screen sharing in Chrome and Android WebView, hide sensitive information automatically.
Scam detection for chat notifications, introduced on Pixel phones last year, is expanding to Honor, Motorola, Oppo, OnePlus, Realme, Tecno, Vivo, Xiaomi, and others. Google says it plans to reach hundreds of millions more people later this year. That is a plan, not coverage that is already done.
[1]This is not the system already on the site
The piece has no accuracy, no false-alarm rate, and no day on which enhanced protection is available on a named phone. What is fixed: the message setting is opt-in, the cloud model looks at unrecognized senders, link checks stay on the small on-device model, and forwarding and screen sharing are separate controls.
It is also not the Singapore government check, already published, that stays on the phone with Gemma. Both deal with scam text. The product and the publisher are different.
