Google uses that information to provide spam warnings in Messages. Thus, the feature works similar to Truecaller's spam detection functionality. That contrasts spam reports manually sent by users to Google, which include the full message sent by the spammer (plus, a copy may be sent to mobile carriers as well). This new "spam protection" feature will also appear in the "Advanced" section of the settings menu (Settings - Advanced), allowing users to manually activate or deactivate it. If you're an avid Messages user, you'll undoubtedly see the feature the day it becomes available to you.
Google has been revamping their message app with little tweaks in design UI and introducing features like "Dark Mode" in a bid to make it a much better competitor against the likes of WhatsApp, Messenger, and iMessage.
The popup notification users receive when the so-called Spam Protection function hits the devices asks the users to either enable it or keep it off. However, Google says it doesn't save your phone number or the content of texts.
Android Police also previously discovered a Google support page that went live prematurely with details on how spam protection works. It's a feature that will be automatically enabled, but you can venture into the settings and disable it if you choose.
The good news here is that personal information such as phone number and content of their message will be stripped off and not included in the information sent to Google.
But in the coming weeks, the service could be shifted to "messages.google.com", the report said, citing an upcoming change to Chrome OS.
Just a few months ago, Google rolled out Call Screen feature to all old Pixel phone to curb irritating telemarketing calls and now the search engine giant is reportedly releasing a major update for message app to block SMS spam.
