How to Remove Repeated Contacts on Xiaomi: The Complete Guide

Duplicate contacts on Xiaomi smartphones are a common problem that occurs after synchronization with multiple accounts (Google, Mi Account, SIM-card), import backups or malfunctions MIUI. The same names with different phone numbers, or the same numbers with different names, not only clutter the phone book, but also make it harder to find the right subscriber. In this article, we will discuss all the working ways to remove duplicates from embedded tools. MIUI 14/13 up to third-party applications and manual cleaning.

Xiaomi is a system that can create duplicates even when synchronized correctly — for example, if the contact is stored in both Google Contacts and device memory. We tested all methods on Redmi Note 12 Pro+, POCO X5 Pro and Xiaomi 13 Ultra models with the latest firmware versions. Importantly, before cleaning, back up contacts — this will save you from losing data if you miss an error.

Why do you have duplicate contacts on Xiaomi?

The reasons for the duplicate contacts on Xiaomi fall into two categories: system and user. The first include MIUI bugs, when after updating the firmware or resetting the system incorrectly combines data from different sources. For example, MIUI 14 had a bug in which the contacts from WhatsApp were duplicated in the main phone book, even if the sync with the messenger is disabled.

User errors are more common:

• 🔄 Multiple syncs with one account (e.g. Google and Mi Account at the same time).
• 📱 Import contacts from an old phone without first cleaning the duplicates.
• 📇 Manually adding the same contact to different accounts (for example, to phone memory and to the user’s account). SIM-map).
• 🔄 Update firmware without resetting the app cache Contacts.

Another common situation is that duplicates appear after you use backup applications like Mi Mover or ShareMe, which sometimes create separate copies of contacts instead of combining them, and if you notice that duplicates appear after you transfer data, check the sync settings in those applications.

Method 1: Integrated contact association in MIUI

The fastest and safest method is to use the built-in MIUI Contacts Association tool, which is available on all modern Xiaomi smartphones, including Redmi, POCO and Black Shark.

1. Open the Contacts app (an icon with a person’s silhouette).
2. Slip on three dots in the top right corner and select Contact Management.
3. Go to the section "Connect Contacts".
4. The system will automatically find all the takes and suggest that they be combined. Press Combine all or select specific pairs manually.
5. Confirm the action by pressing Ready.

If you don’t have the option to Join Contacts, update the Contacts app via Google Play or check the MIUI version in the settings (About Phone → MIUI Version). On older versions (below MIUI 12), this tool may be hidden.

⚠️ Note: If some contacts are missing after the merger, check the Archive folder in the Contacts app. MIUI Automatically archives suspicious duplicates instead of deleting them.

Method 2: Cleaning up through Google Contacts

If the duplicates are synced to Google, the easiest way to clear them is through the web version of Google Contacts, which works even if the phone has lost access to the Internet.

1. Open your browser on your PC or phone and go to: contacts.google.com.
2. Sign in with the same Google account that is linked to your phone.
3. In the left menu, select Doubley, and the system will show all the repeated contacts.
4. Click Combine All or select specific duplicates to manually combine.
5. After cleaning, go back to your phone and update your contacts by pulling the list down.

The advantage of this is centralized management, and all changes are automatically synchronized with the phone, so that the duplicates don't come back, but if the contacts are duplicated not only in Google, but also in the device's memory, you have to use additional methods.

⚠️ Note: If you use Mi Account for sync, duplicates can be saved to the Xiaomi cloud. To delete them, go to account.xiaomi.com, go to the Cloud → Contact and manually clean repetitive records.

Method 3: Third-party applications for removing duplicates

If the built-in tools didn't work, you can use specialized applications, and we tested some of the most popular tools and selected the most reliable ones:

• 📱 Simpler Merge Duplicates — automatically finds and merges duplicates, supports backup. Plus: works without the Internet.
• 🔍 Contacts Optimizer — not only names, but phone numbers, email, plus flexible filtering settings.
• 🛠️ Cleanup: Duplicate Contacts – Simple interface, support MIUI. Plus: no limit on the number of contacts.

Before using third-party applications:

1. Create a backup of contacts through Settings → Google → Backup.
2. Check the reviews and the rating of the app on Google Play (should be at least 4.2).
3. Limit the application to Contacts only by disabling permissions for SMS, Calls and Location.

💡

Before installing a third-party application, check it on the VirusTotal website – this will help to avoid viruses and spyware.

Important: Apps like Truecaller or GetContact can create new duplicates instead of deleting them, because they add data from their databases to your phone book. If you use such services, turn off the Enrich Contacts option in their settings.

Method 4: Manual cleaning of contacts

If you have a few takes (up to 50), it's easier to remove them manually, which is suitable for spot cleaning when automatic tools fail.

1. Open the Contacts app and tap on three points → Contact Management.
2. Select Show Contacts from and tag all sources (Google, Mi Account, Phone, SIM).
3. You can scroll through the list and find duplicates, and they're usually displayed next to each other or they're named the same with additives like (1), (2).
4. Slip on the take, click Edit and delete the extra information (or the entire contact).
5. To speed up the process, use a name search at the top of the app.

When cleaning manually, pay attention to:

• 📞 Phone numbers – sometimes doubles differ by a single digit or prefix (+7 instead of 8).
• 👤 Names – Check for typos or extra gaps.
• 📧 Email and addresses – they can also be duplicated.

Method 5: Reset and Re-Sync

If none of these methods worked, the radical way is to completely reset contacts and re-sync them, which is effective when duplicates appear due to a MIUI database failure. Importantly, make sure you back up before resetting!

Instructions:

1. Go to Settings → Accounts and Synchronization.
2. Turn off sync for all accounts (Google, Mi Account).
3. Go back to Settings → Applications → Application Management.
4. Find the Contacts app, open its settings and click Storage → Clear the data.
5. Confirm the action. All local contacts will be deleted!
6. Turn on the sync back and wait for the contacts to load from the cloud.

After reset, check the phone book for duplicates, and if they reappear, the problem is source conflict (e.g., the same contacts are saved in both Google and Mi Account).

• Select one primary source (like Google Contacts) and turn off sync for the rest.
• Export contacts from all sources to individual.vcf files and merge them manually on your PC.

💡

Contact resets are a last resort, and only use them if other methods have not worked, as this can lead to data loss if backed up incorrectly.

How to Prevent the appearance of doubles in the future

To prevent duplicate contacts from appearing again, follow these rules:

• 🔄 Sync with only one source (e.g., only Google or only Mi Account).
• 📱 Turn off automatic import of contacts in messengers (WhatsApp, Telegram, Viber).
• 🔄 Regularly clean the cache of the Contacts app (Settings) → Annexes → Contacts → Kesh).
• 📇 Don't keep in touch with me. SIM-The map is the most frequent source of duplicates.
• 🔄 Update. MIUI to the latest version - in the new firmware, duplicate bugs are corrected.

If you often migrate contacts between devices, use cloud services (Google Contacts or iCloud for iPhone) instead of local export/import. This minimizes the risk of creating duplicates. It is also useful to set up automatic backup in Settings → Google → Backup – this will allow you to quickly restore contacts without loss.
