Does anyone know more on how this works? The original post references that "Caller ID must be enabled". Is this feature going to send all my incoming phone cal

  If you have Caller ID enabled on a Nexus device, all of your incoming phone call numbers are already being sent to Google. Google almost certainly uses this metadata to try to identify spammers, like Gmail uses all of your mail to detect spam. The same caller calling many of their users in short succession could be more likely to be a spam caller, for instance.

  Called ID looks up phone numbers and replaces them with the names of businesses. It does send the phone number to Google to look it up, and it does work internationally. I've lived in both Australia and Vietnam with great results. The feature has been available for a long time and is fantastic in my opinion. When an unknown number dials it gets replaced on the screen in ~1-2 seconds with the business name, which is really useful.
