How to Merge Duplicate Contacts on Android

Merge duplicate contacts on Android using Google Contacts' Merge & fix tool, a manual merge, or Samsung's built-in cleanup, and undo mistakes.

Duplicate contacts almost always live in your Google account, so one built-in tool cleans up nearly any Android phone. Open the Contacts app, pick your Google account at the top, then tap Fix & manage followed by Merge & fix and Merge duplicates. Review each pair and tap Merge, or clear the whole list at once with Merge all. One thing trips up Samsung owners in particular: the same person often shows twice because one copy sits in your Google account and the other in your Samsung account, and Google’s tool will not merge across the two — a Pixel usually keeps everyone in the single Google account, so its scan catches almost all of them.

Use Google’s Merge & fix tool

This scanner compares the contacts in one account and flags likely matches. It works the same in the app and at contacts.google.com. No Merge duplicates option means Google found no matches here.

Before a big cleanup, keep a copy. See how to back up your Android phone in case a merge goes sideways.

Merge two contacts by hand

When you already know two entries are the same person, skip the scan. Tap More, choose Select, tap both entries, then open More again and pick Merge. This helps when each copy holds different details, like a number on one and an email on the other.

Google only merges contacts in the same account, so a repeating name is often a device or SIM copy.

Samsung phones have their own tool

On a Galaxy, open Samsung’s Contacts app and tap the menu (the three lines). Tap Manage contacts, then Merge contacts to combine matches by number, email, or name. The same menu also has a Delete duplicate contacts cleanup for exact copies. Tidy contacts help with everyday tasks, like when you need to block a number on Android.

Undo a merge or restore a contact

Mistakes stay reversible for a while. In Contacts settings, in the app or on the web, choose Undo changes to roll your whole list back to any point in the past 30 days. A deleted contact also sits in Trash for 30 days, where you can recover it.

Run Merge & fix first, handle stragglers by hand, then check the merged card kept the right number, email, and photo.

Common questions

Why won’t my duplicate contacts merge?

Google only merges duplicates that live in the same account. Copies split across two Google accounts, or a Samsung-account entry sitting next to a Google one, will not combine until you move them into a single account. Names spelled differently may also go unflagged, so merge those by hand.

How do I merge contacts saved in two different Google accounts?

There is no cross-account merge. Export the contacts from one account and import them into the other, or move them so everyone lands in one account, then run Merge & fix. Consolidating into a single account first is what lets the scanner see them as duplicates.

Can I undo a contact merge on Android?

Yes. In Contacts settings, choose Undo changes to roll your whole list back to any point in the past 30 days. A contact you deleted also stays in Trash for 30 days, where you can restore it.

Why do duplicate contacts keep coming back after I merge them?

A duplicate that reappears is usually a second sync source adding it again, such as a SIM copy, a Samsung account, or a second Google account. Turn off or consolidate the extra source so it stops repopulating your list.
