Google's Call Screen feature has been a boon to Pixel 3 owners wary of tedious telemarketing calls. Instead of taking your chances on an incoming 'Scam Likely' call, you can just get Google Assistant to answer for you. One of the major criticisms of the service, though, is that once the call is complete, the transcript of the conversation disappears. So unless you managed to grab a screenshot of the transcript, or were paying attention to the screen during the call, you'd have nothing to refer to later beyond a caller number. None of this is really conducive to fuss-free spam filtering. But Google has been paying attention to feedback, and it seems that Call Screen transcripts are on the way.
