 any unrecognized calls that are not in your contact list yeah and it shouldn't just be for you i think scams are sort of a community problem so you've got to look out for you know the people you know the people you love which is to say if there's somebody in your family that is more susceptible to scams turn on these settings in their phone make it so that any calls that aren't from people saved in their address book go directly to voicemail
