Screen call is such a good feature. For those that don't know, Pixel devices allow you to press a "Screen Call" button when you receive a call.
For the caller, they'll hear a Google Assistant voice that says, "Hi, the person you're calling is using a screening service from Google and will get a copy of this conversation. Go ahead and say your name and why you're calling."
As the caller speaks, the conversation is transcribed in real-time to your phone. If you know the person, you can pick up. If it's a spam call, you can press "Block Number and Report Spam."
It's an okay feature. The feature I really wish they had is to auto-reject any calls not on my contact list. I'm just glad they finally added auto-rejecting any calls considered spam by their systems.
Google Voice has a similar screening service. From the GV help forum ...
"when call screening is enabled:
If the caller's name and phone number are in your Google Contacts, or the caller is a business known to Google (e.g. it shows up in Google Maps with an information box), then that name will be played to you. If the caller's number is not in either of those places, then their calls will be screened every time, until/unless you add them to Contacts."
