How do I stop incoming calls on a Nexus 6P running Android 8.1? TIA.

Previous searches just don't work. I get so many junk calls, I would just prefer them being in my contacts, or no-go. Thanks...

Welcome to Android Central! Google's Phone app on your phone doesn't identify Scam Calls? Open your Phone app, tap Menu>Settings, and see if there's a Caller ID & Spam option. Make sure the toggles for Caller ID & Spam and Filter Spam Calls are turned on.

I moved this from the Android Apps forum to the Nexus 6P forum, since the former is intended for developers to promote their apps.
