Wow. It sounds like LG is all over it.
@John66 CT Mr. Number says in the opening line of the description that it can block by Area Code. The Samsung dialer options are not as detailed as what is being reported for the LG but for me the issue with being able to block Area Codes is that most of my spam calls are spoofs of my Area Code and then I would essentially be unable to receive any call from anyone not in my contacts. I don't know what the answer might be but cutting off your nose to spite your face is not my idea of a solution. Also as for blocking the numbers as they come in that's pointless as well since the number is rarely the same twice or even if it is twice almost never three times. So you end up with a thousand numbers blocked but it doesn't help.
