Why Xiaomi has duplicate contacts and how to fix it
Duplicate contacts on Xiaomi, Redmi or POCO smartphones are a common problem that arises from synchronization with multiple accounts, import errors or failures in the standard Contacts app. Most often, users experience a situation where the same phone number is displayed twice (or even three times) under different names - for example, "Ivan Ivanov" and "Ivan" with the same number. In some cases, duplicates appear after updating MIUI or transferring data from an old phone.
In this article, we will discuss 5 proven ways to delete duplicate numbers, from standard MIUI tools to third-party applications, and explain how to prevent duplicates in the future. It is important to understand that the methods differ in complexity and effectiveness: for example, manual deletion is suitable for 5-10 contacts, and mass cleaning will require exporting data to a file. If you are not sure of your actions, make a backup through Settings → Google → Backup – this will save you from losing important numbers.
The reasons for the duplicate contacts on Xiaomi:
- 🔄 Synchronization with multiple accounts (Google, Mi Account, SIM-map, WhatsApp).
- 📱 Transfer data from the old phone through MI Mover or backup.
- 🔄 Errors of the Contacts app after the update MIUI.
- 📥 Import contacts from the file VCF repeatable.
- 🤖 Automatic contact creation by messengers (Telegram, Viber).
Method 1: Remove duplicates through the standard Contacts app
The easiest method is to use the built-in contact merging function in the Contacts app (or Contacts on global firmware), which is suitable if there are few duplicate entries (up to 50-100).
Instructions:
- Open the Contacts app on your Xiaomi.
- Press three points (⋮) In the upper right corner, select Contact Management (or Manage Contacts).
- Use the Merge Contacts (Merge Contacts)
- The system will automatically find possible duplicates, and in front of each sentence, there will be a "Unite - press" button to merge the records.
- For manual search, enter the contact name in the search bar and select Edit to remove the extra entry.
Limitations of the method:
- ❌ Does not find duplicates if the names of the records are very different (for example, "Ivan" and "Vanya»).
- ❌ It does not work with contacts that are only tied to SIM-map.
- ❌ You may miss duplicates if you have numbers saved in different accounts (Google and Mi Account).
⚠️ Note: If important data (such as an additional number or email) is missing after the merger, check the Archive folder in the Contacts app - deleted records get there within 30 days.
Method 2: Clearing duplicates through Google Account
If contacts are synced to a Google Account, they can be cleared through the web version of Google Contacts, a method that is effective when duplicate entries are linked to multiple accounts (e.g., work and personal email).
Step-by-step:
- Open contacts.google.com on your computer or phone and log in with the same account as you do on Xiaomi.
- On the left menu, select Duplicates, and the system will show all the duplicate contacts.
- Click Merge all or select specific duplicates to merge.
- After cleaning, go back to your phone and update your contacts: open Settings → Accounts → Google → Sync and tap Sync Now.
Advantages of the method:
- ✅ It works even if the duplicates are created in different Google accounts.
- ✅ Allows you to restore remote contacts within 30 days through the Recycle Bin.
- ✅ The interface is more convenient than in the mobile application.

Method 3: Export and import contacts for mass cleaning

- Export: Open Contacts → ⋮ → Contact management → Imports/Exports → Export to file. Choose where to export from (Google, SIM, phone) and save the contact.vcf file.
- Cleanup of Doubles: Use one of the PC apps: 🖥️ Outlook (import) VCF → tool “Delete duplicates»). 🖥️ Google Contacts (download) VCF at contacts.google.com and use the merger function). 🖥️ Specialized utilities (e.g. Duplicate Contacts Remover) Windows/Mac).
Import:
Contact management → Delete everything
Important nuances:
- 🔹 Before removing all contacts, turn off synchronization with Google/Mi Accounts to avoid losing data in the cloud.
- 🔹 If you use Outlook after importing VCF Check the Duplicates folder – the program does not always delete them automatically.
- 🔹 For large bases (1000)+ Duplicate Contacts Remover is better for finding repetitions by numbers rather than names.
