How to combine duplicate contacts on Xiaomi Redmi Note 10: 5 working ways

Duplicate contacts on the Xiaomi Redmi Note 10 are a common problem that occurs after syncing with multiple accounts (Google, Mi Account, Sim cards) or importing backups from different sources, resulting in a phone book clogged with repeating entries with the same names but different numbers, email or photos, which not only makes it harder to find the right subscriber, but also increases the weight of the backup, slows down the Contacts app.

In this article, you’ll find 5 proven ways to combine duplicates, from built-in MIUI tools to manually editing through Google Contacts. We’ll take a look at the nuances for different firmware versions (MIUI 12/13/14), show you how to avoid data loss during a merger, and give you tips to prevent duplicates in the future. If your Redmi Note 10 is filled with “clones” of contacts, read on.

Why do you have duplicate contacts on the Redmi Note 10?

The main reason for the duplication is multiple synchronization sources. Xiaomi’s smartphone can pull data from:

• 📱 Local phone book (stored only on the device)
• ☁️ Google Account (Synced with the Cloud)
• 🔄 Mi Account (Xiaomi Cloud)
• 📶 SIM-cards (if the contacts are stored on it)
• 📲 Third-party applications (WhatsApp, Viber, Telegram)

When you add a contact manually, it can be saved to Local Contacts, and the next time you sign in to a Google Account, it can be duplicated in the cloud, and the same happens when you import a backup from an old phone or after you reset your settings, for example, if you used Samsung and moved your contacts over a.vcf file and then synced them to your Mi Account, the system will create copies.

On the Redmi Note. 10 The doubles often appear after the update MIUI before 13/14 Because of the change in sync logic with Xiaomi Cloud, newer versions of the firmware may cause Mi Account contacts to conflict with Google data if both accounts are active, and the problem is common for users who frequently change their accounts.

Method 1: Connecting through the standard Contacts app

The easiest method is to use the built-in merging function in the Contacts app (an icon with a person's silhouette on a green background), which works on all versions of MIUI and does not require an Internet connection.

1. Open the Contacts app → press three points (⋮) top-right → Select Contact Management.
2. Go to the "Connect" section (may be called "Find and combine takes" in MIUI 14).
3. The system will automatically scan the phone book and show you a list of duplicate records, and opposite each take will be a "Combine" button.
4. Press the button and confirm the merger. Repeat for all the takes you find.

If the automatic search didn’t find all the takes, try manually:

• 🔍 Enter the contact name in the application search bar.
• 📋 Press the contact. → Edit → Scroll down and select Combine with another contact.
• ✅ Check the duplicate records and click Ready.

Limitation: This method only works for contacts saved in the Local Phone Book or Mi Account. Doubles from Google Account will have to be combined through the web version of Google Contacts (see Method 3).
