Google starts rolling out new Spam protection feature

After half a year development, spam protection in Android messages finally started rolling out earlier this month to some users. The feature is yet to be made available to everyone which means the change may be server-side and limited for the meantime. However, we may see a full rollout sometime soon. When the update gets to any Android phone, a new notifications will pop-up on the device showing the new spam protection. 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.

How this spam protection feature works is undefined, but possibly it observes the data statistically to examine similarities between spam messages so as to detect them. If you forward a spam report manually to Google it still submits the phone numbers of both the sender and the recipient including the message body. If you are so concerned about privacy implications that might emanate, and having Google to access your Information, you might literally not be needing this feature, presumably using a different app might save you the stress.
