I purchased a Samsung A16 5G and added a line to my Verizon wireless account to begin transitioning from my current iPhone to Android (fed up with Apple locking features to only working or sharing with their devices).  For the most part, I am satisfied with Android except for the ability to block unwanted calls.  This may force me to abandon my switch to Android.  I have tried "Block calls from unknown numbers" in the phone app settings, but that did not work.  I have tried "Block spam and scam calls" using Hiya and that did not work.   I have also tried setting Do Not Disturb so that only calls in my contacts will come through, but that did not work.  Verizon call filter also does not seem to help.

What I WANT to see is "if the caller is not in my contacts then DO NOT RING".  Simple as that.  Works great on the iPhone.  I cannot understand why setting "Block calls from unknown numbers" on Samsung/Android does not work.  "Unknown" means not in my contacts.  This is important since I get multiple unknown (and unwanted) calls each day.
