Tired of getting unwanted phone calls from telemarketers? Perhaps you have fallen victim to a phone scam or just want to be left alone by that certain someone, everyone has a reason to block unknown callers on your Samsung smartphone. Your Samsung smartphone has an awesome way for stopping unwanted callers in their tracks.
Tap the Phone icon.
Tap More or the Menu icon, then tap Settings.
Tap Call blocking/Call rejection.
You have several options to block incoming calls. Type a phone number, or tap to pick a contact or a recent caller to block.
You’ll also see an option to block anonymous or unknown callers.
