The 5 doesn't have the option like other notes. UGH what happened Samsung? Anyways the Note 5 does have a blacklist. So you will not receive any kind of messages from the person you do not want to hear from. HOWEVER I CAUTION you be careful who you black list because you can't take the person off once they are on. Or at least I have not been able to figure out how yet. In order to see if the person texted you will have to go to their contact and keep going to the contact to see any text.
