In this article, we’ll look at all the current ways to connect contacts on Redmi 9 Pro, from standard features to hidden features and apps from Google Play.

Before you start combining, it is important to understand the reasons for the appearance of doubles. On Redmi 9 Pro, this is usually due to:

• 🔄 Sync with multiple accounts if you add the same contact to Google Contacts, Mi Account and on SIM-The system will create three separate records.
• 📱 Imports from backup: When you restore data from the backup (for example, after resetting settings), contacts can be duplicated.
• 🤖 Application errors: Some messengers (WhatsApp, Telegram) create their copies of contacts in the phone book.
• 🔄 Updates MIUI. After major updates (for example, with the MIUI 12 on MIUI 13) sometimes the links to the accounts are lost.

Interestingly, Xiaomi does not automatically combine contacts even with the same names and numbers, which is due to its privacy policy: it cannot independently decide on data merging from different sources (e.g. Google and SIM), so the user has to do it manually.

⚠️ Note: If you are using a double SIM-A card on Redmi 9 Pro may have duplicates because the contacts are saved to each card separately. Before combining, check which storage is the main record (in the contact settings).

Method 1: Connecting contacts through the standard Contacts app

The easiest method is to use the built-in merger function in the Contacts app (or Phone, depending on the version of MIUI), which works for contacts saved in the device's phone book or Google account.

Instructions:

1. Open the Contacts app on Redmi 9 Pro.
2. Press three points (⋮) in the upper right corner and select Contact Management → Connecting contacts.
3. The system will automatically find possible duplicates, and there will be a + icon opposite each proposed merger, and click on it to confirm the merger.
4. For manual doubles search, use the search bar at the top of the screen.

If the Connect Contacts option is not available, update the Contacts app via Google Play or check the MIUI version (in older builds, the feature may be hidden).

Method 2: Using Google Contacts to Merger

If contacts are synced to a Google account, it’s more convenient to combine them through the web version of Google Contacts, a method that is suitable for users who store the main phone book in the cloud.

Step-by-step:

1. Open your browser on your PC or phone and go to contacts.google.com.
2. Sign in with the same account that is linked to Redmi 9 Pro.

4. Click Combine opposite each take or choose Combine all (if you are sure of the match accuracy).
5. After the merger, wait for sync (usually takes 1-2 minutes) and check the changes on the phone.

The advantage of this method is the ability to mass combine and preview changes, but be careful: if there are unique data in the duplicates (for example, different phone numbers or email addresses), they will be lost in the automatic merger.

2. Click on the contact, then select Edit (pencil icon).
3. Scroll down and click Combine with another contact.
4. Select from the list the record with which you want to combine the current contact, the system will offer to save all the unique data (numbers, email, addresses).

This method is especially useful if duplicates have different names (e.g., Ivan Petrov and Vanya) or additional fields (work/personal number), and it allows you to save the call and message history associated with both contacts - after the merger it will be combined into a single chain.

⚠️ Note: If you combine contacts from different sources (e.g. Google and Google) SIM-map), the main record will be stored in the storage you selected during the edit. Make sure that this is the correct account, otherwise the data may disappear after deleting. SIM.
