How to combine duplicate contacts on Xiaomi: 5 proven ways

On smartphones Xiaomi, Redmi and POCO Duplicate contacts are a common problem that occurs when synchronizing with multiple accounts (Google, Mi Account, SIM-Import from backups or contact errors: A single person's scattered records not only clutter up the phone book, but also make it harder to find the number you want, like you might have three records for a colleague of Ivan Petrov's: One with a work number, the second with a personal number, and the third with a mail, but without a phone.

In this article, we’ll break down 5 working ways to connect with Xiaomi, including standard tools. MIUI, Google Contacts and third-party utilities: You'll learn how to automatically find and drain duplicates, manually edit records, and prevent new copies from appearing. We'll focus on synchronization and backup, steps that are often overlooked, resulting in data loss.

Why do you have duplicate contacts on Xiaomi?

The reasons for the duplicate contacts on Xiaomi are divided into two groups: system (related to work). MIUI) and user (record management errors). Let's look at the main ones:

• 🔄 Sync with multiple accounts: If you add a Google account, Mi Account, and corporate email (e.g. Exchange) to your phone, each of them can create a separate record for the same contact. For example, a Gmail colleague and the same Outlook colleague will appear as two different people.
• 📱 Imports from SIM-When transferring contacts from an old phone via a.vcf file or Mi Mover, copies of existing records are often created, especially if the data are partially the same (for example, the same name but different numbers).
• 🤖 Errors of the Contacts app. In some versions MIUI (particularly MIUI 12-14) a duplication bug was present when editing records or updating the system, for example, after upgrading to MIUI 14 users complained about the automatic creation of copies of contacts with the prefix "(1)».
• ☁️ Cloud conflicts: If you use Google Contacts and Mi Cloud at the same time, their sync algorithms can argue over the priority of recording by creating duplicates, for example, Google can count the primary number from Gmail, and Mi Cloud can count from Mi Account.

To pinpoint the source of the duplicates, check which account each post is linked to. Open the contact in the Contacts app, click Edit and look at the Account field (usually at the top of the screen). If it says Google, Mi Account or Local, that's the key to understanding the problem.

Method 1: Connecting contacts through the standard Contacts app

The easiest method is to use the built-in merge feature in the Contacts app from Xiaomi. It is available on all smartphones with a smartphone. MIUI 10 and newer, including the Redmi Note 10/11/12, POCO X3/X4/X5 and Xiaomi flagships 12/13/14. The algorithm of the work:

1. Open the Contacts app (an icon with a person’s silhouette on a green background).
2. Press three points (⋮) in the upper right corner and select Contact Management → Connecting contacts.
3. The system will automatically find possible duplicates. Opposite each sentence will be a "Unite" button.
4. Check the data in both records (numbers, mail, addresses) and press Combine. Repeat for all takes.

It's important, in some versions. MIUI (for example, MIUI 13 Global) the unification function is hidden deeper. If it is not in the Contact Management menu, try the path: Settings → System applications → Contacts → Connecting contacts.

Make a backup of contacts (export to.vcf)

Check which account the duplicates are linked to

Make sure there are no conflicting data in the records (e.g. different birthdays)

Disable cloud sync during merger-->

If the automatic unification didn’t work or missed some takes, try manual mode:

1. Open a contact that needs to be combined.
2. Press Edit. → three-point (⋮) → Combining with another contact.
3. Select a duplicate entry from the list and confirm the merger.

💡

If you have lost some numbers or mail after the merger, check the Recycle Bin folder in the Contacts app, and you can recover deleted data within 30 days.

Method 2: Using Google Contacts to Merge Duties

If your contacts are synced to a Google account, it is more convenient to combine them through the web version of Google Contacts, a method that is suitable for users whose main source of records is Gmail or Android with a link to Google.

• 🌐 Access from any device (PC, tablet, other phone).
• 🔍 More accurate algorithm for finding duplicates than in MIUI.
• 📊 Possibility of mass unification (up to 50 contacts at a time).

Step instructions:

1. Open your browser on your PC or phone and go to contacts.google.com. Sign in with the same account as you do on Xiaomi.
2. In the left menu, select Doubles (or Combine and Fix → Find Doubles).
3. The system will show you a list of possible takes, and in front of each pair, you'll have a Combine button, press it, and check the data in the combined record.
4. After the merger, wait for synchronization (usually takes 1-5 minutes) and check the result on your phone.

A critical caveat: if you use multiple Google accounts on Xiaomi, disable sync for all but the main one before the merger, otherwise the duplicates may reappear the next contact update.

1. Go to Settings → Accounts and Synchronization.
2. Select an unnecessary Google account → Synchronization of contacts → turn off the slider.

💡

If after combining in Google Contacts, the duplicates remained on Xiaomi, check if the sync in the account settings is disabled. MIUI Blocks background data updates to save battery.

Method 3: Applications for cleaning contacts (Simpler Merge, Contacts Optimizer)

If the built-in tools don't work, use third-party apps that offer advanced features such as:

• 🔍 In-depth analysis of doubles by several criteria (name, number, post, birthday).
• 📊 Group association (for example, all contacts with the same name).
• 🧹 Cleaning of empty records (no numbers or names).
• 🔄 Backup before changes.

We tested 5 popular utilities and selected the two most reliable:

1. Simpler Merge (Contacts & Duplicate Remover)

Pros: simple interface, support for the Russian language, free version with basic features. Cons: advertising in the free version, a limit on the number of associations (up to 10 per day).

How to use:

1. Download the app from Google Play.
2. Start the scan (the button Find duplicates).
3. Select contacts for the merger and click Consolidate.
4. Confirm the changes and wait for the process to be completed.

2. Contacts Optimizer

Pros: advanced filters (search for name, number), export of the report on duplicates. Cons: paid version for mass association (from 150) ₽).

Instructions:

1. Install the app from Google Play.
2. In the menu, select Duplicates. → Scan.
3. Check the contacts for the merger and click Optimize.
4. Check the result in the main Contacts app.

⚠️ Attention! Before using third-party apps, turn off sync with Google and Mi Cloud in Xiaomi settings. This will prevent conflicts when combining.

Method 4: Manual editing and export/import of contacts

If the automatic methods don't work, then manually pairing is left, and it takes longer, but it guarantees 100% control over the process, and is suitable for users with a small number of takes (up to 50 records).

Algorithm of action:

1. Export contacts to.vcf file: Open Contacts → ⋮ → Contact management → Import/Export. Select Export to file and save backup to your phone or Google Drive.
2. Open a.vcf file on a PC: Connect your phone to your computer or download a file from the cloud. Open.vcf in a text editor (like Notepad).++) Specialized programs (Microsoft Outlook, Thunderbird).
3. Find and combine takes: Manually compare entries with the same names. Copy unique data (numbers, mail) from take to main entry. Delete the extra lines (each.vcf entry begins with a copy of the unique data (numbers, mail) BEGIN:VCARD ends END:VCARD).
4. Import back: Save the edited file. In the Contacts app on Xiaomi, select Import from the file and specify the path to.vcf.

Example of.vcf file structure (to understand what duplicates look like):

BEGIN:VCARD


VERSION:3.0




FN: Ivan Petrov




TEL;TYPE=CELL:+79123456789




EMAIL:ivan@mail.ru




END:VCARD




BEGIN:VCARD




VERSION:3.0




FN: Ivan Petrov




TEL;TYPE=WORK:+79876543210




END:VCARD

⚠️ Attention! When you manually edit.vcf, it is easy to make a syntax error that will result in data loss, VCF Validator.

Method 5: Reset and re-synchronize contacts

The last method is to completely reset contacts and then synchronize them from a reliable source, and it's worth using if:

• 🔄 The doubles appear again after any combination.
• 📵 Contacts are “multiplied” after each update MIUI.
• ☁️ You are sure that Google Contacts or Mi Cloud has a clean version of the phone book.

Step-by-step:

1. Backup: Export contacts to.vcf (see Method 4). Copy the file to your PC or Google Drive.
2. Delete all contacts from your phone: Go to Contacts → ⋮ → Contact management → Delete all contacts. Select all accounts (Google, Mi Account, SIM) and confirm the removal.
3. Turn off synchronization: In Settings → Accounts and sync disable contact sync for all accounts.
4. Restore contacts from a trusted source: If the clean version is in Google Contacts: enable sync only for this account. If the clean version is in.vcf: import it through Contacts → Imports.
5. Check the result: Make sure the duplicates don't show up again. Turn on sync for the other accounts (one by one, with verification after each).

Important: Don't sync all accounts at once after reset, do it in stages, starting with the most reliable source (like Google), and if the duplicates come back, you'll know which account is to blame.

How can we prevent the appearance of doubles in the future?

To avoid recurring problems, follow these rules:

• 🔗 Use one primary account to sync (e.g., Google only or Mi Account only) and avoid syncing with multiple services at the same time.
• 📥 Import contacts neatly: When transferring data from an old phone, choose Add to existing ones rather than Replace everything. Before importing from.vcf, check the file for duplicates (open in Google Contacts).
• 🔄 Update. MIUI: In the new versions MIUI 14+ Fixed contact duplication bugs. Check the updates in Settings → The phone. → Updating the system.
• 📌 Clean contacts regularly: Every 2-3 months, run a double check through Google Contacts or Settings → Contacts → Unite.

If you frequently work with contacts from multiple sources (e.g., you have work and personal email), set up your Google Contacts merger rules:

1. Go to contacts.google.com.
2. Press Settings (cogs) → Other settings.
3. Turn on the option to automatically combine duplicates.

💡

On Xiaomi phones with MIUI 14 Global and newer contacts are less likely to appear due to an improved synchronization algorithm. If you have an older firmware version, consider updating your contacts.

Frequent Mistakes and How to Avoid Them

When connecting contacts, users often make mistakes that lead to data loss or the return of duplicates.

Another common problem is contacting the same numbers, but different names. For example, you might have a "Mom" record with a number. +79123456789 and the recording of Anna Ivanovna with the same number:

• Open both records and compare additional data (mail, birthday, notes).
• Leave a more complete record, and remove the extra or combine manually.
• If both records are important (for example, one person’s home and work contacts), add the tags: “Anna Ivanovna (Mama)” and “Anna Ivanovna (Work)” to the name.
