You can finally set your phone to ignore phone calls from numbers that are not in your contact list. In the last several years the absolute majority of the phone calls I was receiving were the robocalls. Today after upgrading my phone I turned on this feature and finally my phone only rang when a live breathing Homo sapiens was calling me! I hope today is the beginning of the end of the terror of the robocalls!
Can you set it so that those unknown calls are still sent to voicemail? I never answer unknown callers, but I have had legitimate unknown callers that I needed to talk to leave voicemails.
