How to Block Calls from Unknown Numbers on Galaxy Z Flip4

This post will walk you through blocking all incoming calls from unknown callers on the latest Samsung Galaxy Flip smartphone. Here’s a quick guide to block calls from unknown numbers on the Galaxy Z Flip4.

By then, all next incoming calls you’ll get from unknown or unsaved numbers will automatically be stopped and blocked by the system.

Make sure that all phone numbers of your friends, families and relatives are saved in your contacts so that you won’t miss an important call from any of these important people. 

Alternatively, you can make use of a relevant blocking feature in any of the inbuilt apps like Phone, Contacts, and Messages to add a specific phone number to your blocklist.

You can use the in-built spam protection feature and caller ID to block calls from unwanted callers including fraudsters and telemarketers.

You can also add a specific phone number to from your phone’s Recents, Messages or Contacts directory.

All blocked phone numbers will be displayed under the Block numbers menu of the Phone and Messages apps. There is also an option to unblock a phone number in case you accidentally blocked a contact or phone number and you’d want to remove the number from your blocklist.

And that’s how you activate the Android 13/OneUI 5 feature that automatically blocks calls from unknown numbers, particularly on the latest Samsung Galaxy Z Flip 4 smartphone.
