How to remove duplicate contacts on Xiaomi: the complete guide

Duplicate contacts on Xiaomi, Redmi or smartphones POCO — common problem that occurs after synchronization with multiple accounts, importing from SIM-These replays not only clutter the phone book, but also make it difficult to find the right numbers, and sometimes lead to errors when calling or sending messages. In this article, we will discuss all the current ways to clean up duplicates from embedded tools. MIUI to third-party applications and manual editing.

Xiaomi devices often sync contacts with Google Account, Mi Account and local memory, creating chaos when the same number is stored in different sources. For example, after transferring data from an iPhone or other Android device, duplicates can appear even for those who have never encountered such a problem before. MIUI.

Why do you have duplicate contacts on Xiaomi?

Before you start cleaning, you need to understand the root of the problem, and duplicates arise for several reasons, and each requires a different approach:

• 🔄 Multi-account sync: Google Contacts, Mi Cloud and local storage are connected at the same time, and the system creates separate records for each source.
• 📱 Imports from SIM-card or backup: when transferring contacts from another SIM Xiaomi does not always recognize matches and adds new entries on top of existing ones.
• 🔄 Update MIUI: after major updates (for example, with MIUI 12 on MIUI 14) the system may duplicate contacts due to a failure in the database.
• 🤖 Third-party apps: Messengers like WhatsApp or Telegram sometimes create copies of their contacts, which are displayed in the general phone book.

On devices with MIUI 13/14, the problem is compounded by the fact that the system automatically combines contacts from different sources into a single record, but not always correctly. For example, if you have a colleague number saved in Google Contacts and in Mi Cloud, but with different additional fields (for example, an email or an address), Xiaomi can create two separate records instead of one combined.

⚠️ Note: If you use Mi Account for sync, disabling this feature without prior backup may result in contact loss.Before any manipulation, export the phone book to a.vcf file via Contacts → Settings → Exports.

Method 1: Using the built-in MIUI tool to connect contacts

The easiest way is to use the standard MIUI function for merging duplicates, which is available on all modern Xiaomi, Redmi and POCO devices with a firmware version at least MIUI 10, and the tool automatically finds matches by phone numbers or email and suggests combining them.

To take advantage of this function:

1. Open the Contacts app (an icon with a person’s silhouette).
2. Slip on three dots in the upper right corner and select Settings.
3. Go to the Contact Management section → Connecting contacts.
4. The system will scan the phone book and show you a list of duplicates. Click Combine all or select specific records to merge.
5. Confirm the action by pressing Ready.

If the function does not find duplicates or does not work correctly, try the following steps:

• 🔄 Update Contacts via Google Play (sometimes bugs are fixed in new versions).
• 📱 Reboot your smartphone – it will reset the app cache.
• 🔍 Check if synchronization is included in Settings → If it's disabled, turn it on and try again.

On some devices (such as the Xiaomi 12T or Redmi Note 11), the unification feature may not be available in the menu, in which case try the alternative methods described below.

Method 2: Clearing duplicates through Google Contacts

If your contacts are synced with your Google Account, it is most convenient to manage duplicates through the web version of Google Contacts, a method that is suitable for users who use Gmail as their main source of number storage, and the advantage of this method is the ability to massively delete and merge records.

Instructions:

1. Open your browser on your PC or smartphone 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 Doubley. The system will show all the repeated records.
4. Click Combine All or select specific duplicates for manual merge.
5. After cleaning, go back to your smartphone and update your contacts: go to Settings → Accounts → Google → Sync and tap on Sync now.

If the doubles are left, check the following points:

• 🔄 Make sure all your numbers are displayed in Google Contacts.Sometimes some contacts are only stored in Xiaomi’s local memory.
• 📱 In the sync settings on your smartphone, enable the Contacts option for Google Account.

💡

If Google Contacts doesn’t have a “Doubley” option, try opening a page in Chrome in incognito mode or clearing your browser cache. Sometimes the interface doesn’t show up correctly due to extensions or outdated data.

Method 3: Manual removal of duplicates in the Contacts app

If the automatic tools fail, you'll have to manually remove duplicates, which takes longer, but guarantees accurate results, and is suitable for users with a small number of repetitive contacts (up to 50-100 entries).

How to remove duplicates manually:

1. Open the Contacts app on your Xiaomi.
2. Slip on the search icon (magnifying glass) and enter the name or number of the duplicate contact.
3. The system will show all matches. Check each record and delete the extra ones by clicking on the contact → three dots → Delete.
4. To speed up the process, you can sort contacts by Name or Phone Number (option in the settings menu).

When manually removing, consider the following nuances:

• 🔄 If a contact is synced to Google or Mi Cloud, deleting it on your smartphone will result in deletion in the cloud, and make sure you erase the duplicate, not the original record.
• 📱 Local contacts (only stored on the phone) are permanently removed. If in doubt, export them before cleaning.
• 🔍 Pay attention to the source of the contact (displayed in the details of the recording), sometimes duplicates appear from different sources (for example, for example, from different sources, SIM-map and Google).

To speed up the process, you can use filters. For example, in Settings → Contact Management, select Show Contacts with numbers only, which hides records without phones, making it easier to find duplicates.

Method 4: Disable synchronization with Mi Cloud

One of the common reasons for the duplication is the conflict between Google Contacts and Mi Cloud.If you are not using Xiaomi cloud for backup, it can be turned off to avoid duplicates, a method that is especially relevant for users who have moved from an iPhone or other Android devices and moved contacts through Mi Mover.

How to turn off sync with Mi Cloud:

1. Go to Settings → Accounts → Mi Account.
2. Select Synchronization and turn off the slider opposite Contact.
3. Confirm the action by clicking Disable.
4. Go back to the Contacts app and check if there are any duplicates left. If so, delete them manually or through Google Contacts.

After the Mi Cloud shutdown:

• 🔄 All contacts previously synced to Xiaomi’s cloud will remain on the device, but new changes will no longer be duplicated.
• 📱 If you want to completely remove contacts from Mi Cloud, go to i.mi.com, log in and manually clean your phone book.
• 🔍 To avoid data loss, export contacts to.vcf file before disabling.

⚠️ Note: Some models (e.g. Xiaomi 13 Pro or X-ray) POCO F5) Disabling sync with Mi Cloud can cause the Contacts app to reset, and then you have to reconfigure the display and sorting of records.

Method 5: Using third-party applications to clean up duplicates

If the built-in MIUI tools fail, you can use third-party apps, which offer advanced features for finding and removing duplicates, including bulk processing and backup. Below are proven utilities that are compatible with Xiaomi:

Before using third-party applications:

• 🔄 Create a backup of contacts through Settings → Exports.
• 📱 Check out reviews on Google Play – some apps may contain ads or paid features.
• 🔍 Configure permissions: the application will need access to Contacts and Warehouse.

Important: Apps like Contacts Optimizer may conflict with built-in MIUI synchronization. If duplicates reappear after cleaning, turn off automatic sync in account settings.

Method 6: Reset the Contacts app to factory settings

If none of these methods worked, the last resort is to reset the Contacts app to factory status, which will remove all local settings and cache, but will not affect the contacts themselves (if they are synced with Google or Mi Cloud). MIUI 10 and newer.

Instructions:

1. Go to Settings → Applications → Application Management.
2. Find the contact list and tap it.
3. Select Warehouse and Cache.
4. Click Clear Cache and Reset Settings (or Delete Data if there is no such option).
5. Reboot your smartphone.

• 🔄 The Contacts app will go back to standard settings, and you'll have to reconfigure the display, sorting, and sync sources.
• 📱 If contacts are lost, check sync with Google Account or Mi Cloud in Settings → Accounts.
• 🔍 If the doubles remain, try to repeat Method 1 (built-in combination) - after resetting, the tool can earn correctly.

⚠️ Note: On some devices (e.g. Xiaomi Mi 11), resetting the Contacts app may result in the removal of local contacts (not synced to the cloud.

How to Prevent the appearance of doubles in the future

To avoid recurring problems, follow these guidelines:

• 🔄 Choose one primary sync source: Google Contacts or Mi Cloud. Don't use both at the same time.
• 📱 Turn off automatic importation with SIM-maps: in Settings → Contacts → Import/Export uncheck the checkmark with Autoimport SIM.
• 🔍 Check the doubles regularly: once in a while 1-2 Start a built-in unification tool for a month or use Google Contacts.
• 📲 Avoid third-party apps for transferring contacts: they often create repeats. To migrate from your iPhone, use the official Mi Mover.

If you change smartphones frequently or use multiple accounts, set up Google Contacts as your primary source and turn off sync with Mi Cloud.This minimizes the risk of duplication when you switch to a new device.

💡

The most common reason for duplicates is simultaneous sync with Google and Mi Cloud. Choose one source and disable the second to avoid conflict.
