How to Remove Contact Doubles on Xiaomi: A Complete 2026 Guide

Why do you have dual contacts on Xiaomi?

Double (duplicate) contacts on Xiaomi, Redmi or POCO smartphones are a common problem that arises from the features of the MIUI shell and synchronization with different accounts.

• importation of contacts SIM-card-backup;

Simultaneous synchronization with Google Account and Mi Account;

• Updates to MIUI firmware (especially when switching between versions 12 → 13 → 14);

• Use third-party backup applications (such as Mi Mover or ShareMe).

In some cases, duplicates are created automatically when contacts are merged from different sources, for example, if the same number is stored in both the phone book of the device and in Google Contacts. MIUI does not always correctly handle such conflicts, which leads to ghost entries.

It is important to understand that duplicates do not just take up space – they can lead to malfunctions in the Contacts application, errors in calls and even problems with the display of names in messengers (WhatsApp, Telegram).

Method 1: Automatic merger via the Contacts app

The easiest method is to use the built-in merging feature in the standard Contacts app (or Phone in newer versions of MIUI), which works on all models, including the Xiaomi 13/14, Redmi Note 12/11 and POCO F5/X5.

Instructions:

1. Open the Contacts app (a human silhouette icon).
2. Tap it on three points (⋮) in the upper right corner and select "Contact Management".
3. Go to the "Merge Contacts" section (or "Merge Doubles" in MIUI 14).
4. The system will automatically find all possible duplicates. Press "Flee all" or select specific pairs manually.
5. Confirm the action, wait for the process to be completed (it can take up to 1-2 minutes with a large number of contacts).

⚠️ Note: If some contacts are missing after the merger, check the Archive folder in the same menu. Sometimes the system mistakenly archives records instead of combining them.

Method 2: Clean up Google Contacts (for synchronized accounts)

If your contacts are synced to your Google Account, you can delete duplicates through the web version of the service, which is especially true for users who are actively using Gmail or Google Workspace.

Step-by-step:

1. Open your browser on your PC or phone and go to: contacts.google.com.
2. Sign in with the same account that is linked to your Xiaomi.
3. On the left menu, select "Doubles" (or "Combine and fix" → "Find duplicates").
4. The system will show all the repeating recordings. Click "Combine" for automatic merging or select duplicates manually.
5. After completion, click "Export" (Icon) ⋮ → "Export) and save a backup copy in.vcf format.

⚠️ Note: After combining in Google Contacts, wait for full sync on your phone (may take up to a few minutes). 10-15 To speed up the process, go to Settings. → Accounts. → Google → Sync and click "Sync Now".

💡

If the duplicates are left after the merger in Google Contacts, try disabling and re-enable the sync contacts in the Xiaomi account settings. Sometimes this helps to "update" the local database.

Method 3: Manual removal through export/import (for power users)

If automatic merging didn't work, you can use the export, manual editing and re-import method, which takes longer, but is guaranteed to remove all duplicates.

Algorithm of action:

1. Export Contacts: Open Contacts" → ⋮ → "Contact management" → "Import/Export: Select Export to File and save.vcf contacts to internal memory or SD-map.

Method 4: Using Third-Party Applications

If the built-in MIUI tools don't work, you can use specialized applications to clean contacts.

• 📱 Simpler Merge – automatically finds and merges duplicates, supports backup.
• 🔍 Contacts Optimizer – analyzes contacts for not only duplicates, but also empty fields, incorrect numbers.
• 🛠️ Cleanup: Duplicate Contacts – Simple interface, works without registration.

Advantages of third-party applications:

• More flexible merger settings (you can choose which fields to save when combining).
• Support for mass operations (e.g., removing all take-offs with one tap).
• Additional functions: correction of number formats, removal of irrelevant contacts.

⚠️ Warning: Before using third-party apps, turn off autosynchronization of contacts in Xiaomi settings (Settings) → Accounts. → Synchronization. This will prevent the creation of new duplicates during cleaning.

Method 5: Reset the Contacts app (last resort)

If none of these methods worked, you can try resetting the Contacts app to factory settings, which will delete all local data, but save contacts synchronized with Google or Mi Account.

Instructions:

1. Go to Settings → Applications → Application Management.
2. Find the Contacts app (or Phone) and tap on it.
3. Select "Storage" → "Clear Data" and "Clear Cache".
4. Reboot the phone.
5. After activation, wait for automatic synchronization of contacts from the cloud.

⚠️ Note: This method will delete all local contacts that are not associated with your account. If you have numbers that are stored only on your phone (without sync), pre-export them to the.vcf file.

💡

Resetting the Contacts app is a last resort, only use it if other methods have failed and you have a backup of the data.
