From the makers of this guide
Want the calls screened, not just silenced?
PhoneShield answers your calls first. Known scam numbers are refused before your phone rings, the people you know ring straight through, and everyone else is asked who they are and why they’re calling, so your doctor and the delivery driver still reach you.

One UI 8.5 and later
The phone’s assistant answers calls for you and shows a live transcript, so you can decide whether to pick up.
