Block a Phone Number
Getting repeated calls or texts from the same unknown or unwanted number is more than annoying when your phone keeps ringing at the wrong moment. Samsung phones let you block specific numbers even if they were never saved as a contact. Once a number is on the block list, calls go straight to rejection and messages never reach your inbox.

Change Contact Name Format
If your contacts list shows names as First Name, Last Name and you would rather see Last Name, First Name, the display setting inside the Contacts app controls that order. This has nothing to do with how a contact was originally saved, so switching the format does not touch any contact data. The change only affects how names appear across Calls and Messages, not the underlying entries or numbers.
