I heard iOS 13 has a new built-in feature that blocks all incoming calls, not in your Contacts & silently sends them to voicemail. Does android have something like that? Is there an app that does something like that? if so what is/are the best options? I get so many damn spam calls it drives me crazy! I'm good at adding them to a blocklist but I still get several a day. A feature that blocks calls not in my contacts would be fantastic. Thanks!
