Step by step

1. 

   Open Contacts settings

   In Contacts, tap the three dots at the top right, then Settings.

   Done

2. 

   Tap Merge duplicate contacts

   It is the first row under Manage contacts.

   Done

3. 

   Tick the duplicates

   Number, Email and Name are tabs; a dot marks the ones with matches. Ours said 2 duplicate contacts found. Tick the group, or Select all.

   Done

4. 

   Tap Merge

   The Merge button appears at the bottom once a group is ticked.

   Preview of merged contact shows the name and numbers it will keep. Ours: Test Contact Delta with one mobile number.

   Done

If you do not see this option

• No Manage contacts in the menu? Samsung's steps go Contacts, menu, Manage contacts. On One UI 9 Manage contacts is a section inside Contacts settings. Source: Manage your contacts with ease on your Galaxy phone and tablet

  

• Duplicates by email or name? Samsung says you can merge duplicate numbers, emails or names. Switch tabs at the top of Merge duplicate contacts. Source: Manage your contacts with ease on your Galaxy phone and tablet

If this does not work

• Saving a contact says a duplicate exists? When we saved a second contact with the same number, the phone asked A duplicate contact exists. Merge it? Tap Merge, or Create new to keep both.

  

• No Merge button? It only appears once a group or Select all is ticked. Tick the circle next to the duplicates found line first.

  

About this guide

Merging joins two entries for the same person into one. We merged two test contacts with the same name and number.
