Android phones do it automatically, assuming your carrier hasn't monkeyed with the phone app.
I think Google keeps a spam probability score for callers' phone numbers based on how many people have marked a call as spam.
- tatersolid 7y agoSpam call numbers are randomly generated. Blacklisting can’t work without collateral damage.
- egdod 7y agoI’m surprised it helps at all. Why wouldn’t a robocaller generate a new random number every time?
- manigandham 7y agoThey do. The common strategy is to pick numbers with the same area code to pretend to be legal, and some advanced callers try and pick numbers that match even more recognizable digits (like your office). All this traffic is a major source of revenue for VOIP operators.
