How to Remove Double Contacts in Xiaomi Phone Book: A Complete Guide

Duplicate contacts in the Xiaomi phone book is a common problem that occurs after synchronization with multiple accounts (Google, Mi Account, SIM-card), import backups or malfunctions MIUI. Repeated recordings not only clutter the list, but also make it difficult to find the right numbers, and in some cases lead to errors when calling or sending messages.

In this article, we will discuss 5 working ways to remove duplicates, from built-in MIUI tools to third-party applications, and explain why duplicates appear and how to prevent them from appearing in the future. The instructions are relevant for all modern Xiaomi, Redmi and POCO smartphones based on MIUI 12-14 (including HyperOS).

Why are there double-entry contacts on Xiaomi?

The main reason for duplicate contacts is multiple synchronization, and when you add the same number to different sources (like Google Contacts and MI Accounts), the system perceives them as separate entries, and duplicates arise from:

• 🔄 Import/export contacts from backups (for example, when switching from iPhone to Xiaomi via.vcf file).
• 📱 Failures in work MIUI, When the system creates copies of contacts when updating or resetting settings.
• 📇 Manually adding one number to different accounts (for example, the work number is saved both in Google and in the Internet). SIM-map).
• 🤖 Automatic synchronization with messengers (WhatsApp, Telegram), if they are integrated into the phone book.

Most often, the problem occurs after:

• 🔧 Reflashing the device or reset to factory settings.
• 📲 Connecting a new Google account or MI.
• 📥 Import contacts from an old phone via Bluetooth or Xiaomi Cloud.

⚠️ Note: If the doubles appeared after the update to MIUI 14/HyperOS, Don't rush to remove them manually. First, check your sync settings in Settings. → Accounts – the system may have automatically backed up contacts.

Method 1: Using the built-in MIUI merger tool

MIUI has a built-in function to find and combine duplicate contacts, which does not work perfectly (may miss some takes), but is suitable for most cases.

1. Open the Contacts app (phone book icon).
2. Press three points (⋮) in the upper right corner and select Contact Management.
3. Go to Combine Contacts (or Find Doubles depending on the MIUI version).
4. The system will automatically scan the phone book and suggest a list of takes.Click Combine next to each pair.
5. Confirm the action if necessary.

If the function does not find duplicates, try:

• 🔍 Update the Contacts app via Google Play.
• 📱 Reboot your smartphone – sometimes it helps the system correctly display repeating recordings.

⚠️ Attention: Built-in tool MIUI It does not always recognize duplicates if they are saved in different accounts (for example, one contact in Google, and a copy of it in Mi Account).

Method 2: Delete duplicates through Google Contacts

If your contacts are synced with a Google Account, the easiest way to clear duplicates is through the web version of the service, which is suitable for users who use Gmail as their primary source of contact storage.

1. Open your browser on your computer or phone and go to: contacts.google.com.
2. Sign in with the same Google account that is linked to your Xiaomi.
3. On the left menu, select Dubbles (or Merger and Correct → Find Doubles).
4. The service will automatically find duplicate contacts. Click Consolidate for each pair.
5. Once completed, sync contacts on your phone: go to Settings → Accounts → Google → Sync and enable Contacts.

Advantages of this method:

• 🌐 It works on any device, even if Xiaomi’s smartphone is temporarily unavailable.
• 🔍 More accurate algorithm for finding duplicates compared to the built-in tool MIUI.
• 📱 Changes are automatically applied to all devices linked to a Google account.

If you have any duplicates after the merger, check:

• 🔄 Is the synchronization of contacts in the settings of Xiaomi disabled.
• 📌 Are some contacts saved in other accounts (e.g., Mi Account or on the Internet) SIM-map).

💡

Before mass merging duplicates in Google Contacts, sort the list by name or phone number, which will help you find and check the repeated entries manually faster.

Method 3: Manually linking contacts to MIUI

If the automatic tools fail, you can combine the takes manually, and this takes longer, but it guarantees an accurate result.

1. Open the Contacts app on your Xiaomi.
2. Find the duplicate contact and open the card.
3. Press three points (⋮) in the upper right corner and select Edit.
4. Scroll down and click Combine with another contact.
5. Select a duplicate entry from the list and confirm the merger.

Tips for speeding up the process:

• 🔍 Use a search by name or number to quickly find duplicates.
• 📌 Combine contacts from one source (e.g., first all Google takes, then Mi Account takes).
• 📇 If the doubles are retained on SIM-export them to your phone memory or Google Account first, and then delete them from your phone SIM.

Pay attention to the following nuances:

Method 4: Contact Cleaning Applications (TOP-3)

If the built-in MIUI tools don't work, you can use third-party apps, which offer advanced double-finding, bulk-mergering, and backup, and we tested three of the most reliable solutions:

How to use these applications (for example, Contacts Optimizer):

1. Install the app from Google Play.
2. Start it and give access to the contacts.
3. Click Scan - the program will find all the takes.
4. View the list and select contacts for the merger (or click Combine All).
5. Save changes and sync your contacts with Google or Mi Account.

⚠️ Note: Before using third-party applications, make sure to back up contacts. Some programs may delete important data or incorrectly merge records. Export contacts to a.vcf file via Settings → System system → Backup.

💡

The app side is more effective than the built-in MIUI tools, but it requires caution. Always check reviews and ratings before installing to avoid data leakage.

Method 5: Reset and re-synchronize contacts

If none of the above methods worked, you can try a radical solution: reset all contacts and re-sync them from a reliable source (for example, a Google Account), which is suitable for power users, since it requires prior backup.

Step-by-step:

1. Back up your contacts: Go to Settings → Google → Backup. Make sure Contacts are enabled and click Create Copy Now.
2. Delete all contacts from your device: Open Contacts → Contact Management → Delete everything. Select all sources (Google, Mi Account, SIM) and confirm the deletion.
3. Turn off sync with unnecessary accounts: Go to Settings → Accounts. Turn off contact sync for all accounts except the main one (e.g. leave only Google).

• Go back to Settings → Google → Backup.
• Select the last copy and click Restore.

Once restored, check the phone book for duplicates. If they reappear, the problem is sync settings – contacts are likely automatically imported from multiple sources.

To avoid repeated duplication:

• 🔧 Keep syncing with only one account enabled (Google recommends).
• 📱 Check the contact list regularly for duplicates (every 1-2 months).
• 🚫 Avoid importing contacts from unreliable sources (e.g. via Bluetooth or third-party messengers).

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

To avoid the problem of double contact, follow these recommendations:

• 🔄 Use one primary source to store contacts (e.g., only Google Account). disable sync with Mi Account and SIM-card if they are not needed.
• 📥 Import contacts correctly: When transferring data from another phone, use official tools (Xiaomi Migrate or Google Drive). avoid importing via Bluetooth or.vcf files from unknown sources.
• 🔍 Check your phone book regularly for duplicates (every 1-2 months).
• 📌 Don't save the same number to different accounts, for example, if you already have a work contact on Google, don't add it to your Mi Account.
• 🛡️ Turn off automatic synchronization with messengers (WhatsApp, Viber) if they are integrated into the phone book.

If you change your smartphone frequently or use multiple Xiaomi devices at the same time, set up automatic backups in Google Contacts to avoid data loss and duplication when you switch to a new gadget.

💡

Create a separate tag for important contacts in Google Contacts, which will help you quickly find them even if you have a sync failure.
