The problem of duplicates in the phone book is one of the most common and annoying for owners of modern smartphones, especially after migrating from one device to another. When you upgrade to the new Xiaomi Redmi Note 10, there is often automatic synchronization of data from different sources, such as: SIM-Google or Mi Cloud instead of a single person's record, two or three identical numbers appear on the list, creating chaos and making it difficult to quickly find the right subscriber.
Solving this problem requires not just mechanically deleting redundant records, but understanding how the MIUI contact management system works. Data aggregation is a process where a phone tries to combine information from different places, but sometimes algorithms fail. If you just start deleting numbers manually, you risk losing important data or leaving disparate pieces of information, such as work and personal numbers, that will no longer be linked into a single card.
In this article, we will take a look at all the ways to remove the backbones in the Xiaomi Redmi Note 10, from the built-in cleaning features to advanced methods through the web interface. We will look at why this problem arises, how to properly configure synchronization to avoid repeating it, and which tools are best suited for mass editing a phone book without the risk of data loss.
The reasons for the appearance of duplicates in the MIUI phone book
The main reason for duplicates is that they use multiple storage sources at the same time, and when you restore a backup or log in to your account, the system sees the records on your account. SIM-And it loads contacts from Google in parallel, and because these sources often have different identifiers, the synchronization algorithm perceives them as different objects, even if the phone numbers match.
Another factor is the incorrect combination when changing your device, and if you've previously used an iPhone or a phone from another manufacturer with a different operating system, the format of saving names and numbers may differ. When transferring data to the Redmi Note 10, the system cannot always automatically match Ivanov and Ivanov Ivanov, creating two different cards. SIM-Phone card without prior check.
⚠️ Warning: Before you start any phone book manipulation, be sure to back up.Exporting contacts to.vcf via Google Contacts or Mi Cloud settings will take just a couple of minutes, but save you from losing important numbers in case of an error.
It also affects third-party applications, many users install additional call managers or messengers that request access to contacts and can create their own records or duplicate existing ones for quick access, and application conflict is a real problem when different programs try to manage the same database without coordinating changes between them.
Use of the built-in linking function
The MIUI shell on the Xiaomi Redmi Note 10 has a built-in tool to address this problem, which scans the phone book, finds entries with the same numbers or similar names, and suggests combining them into one card, which is the safest and fastest way to clean up without needing to install additional software.
To use this tool, open the standard Contacts app and go to the settings menu, usually available through three dots in the corner of the screen or a swipe. Find the Contacts Organise or Contact Management section. There will be the "Combine Duplicates" option available. The system will prompt you to view the pairs found and confirm the merger or perform this automatically depending on the firmware version.
- 📱 Open the Contacts app on the home screen.
- ⚙️ Click on the settings menu (three dots or gears).
- 🔗 Select "Combine duplicates" or "Clear duplicates".
- ✅ Confirm the action for all pairs found or select specific ones manually.
It's important to understand that when you combine, the system stores all the unique data from both records, and if one card only listed the number and the other card only listed the email and address, the final record will contain all this information, but manual verification is still recommended, since the algorithm can mistakenly combine contacts of different people with similar names if the numbers do not match completely.
💡
If the built-in feature doesn't find all the takes, try sorting contacts by name in the list. Often duplicate entries are next to each other if the sorting is done correctly, which will make it easier to visually search.
Set up synchronization of Google Contacts
The most reliable way to avoid duplicate issues in the future is to have the right Google account. It's Google account that should be the primary storage for all your numbers. On the Redmi Note 10, sync is automatic, but settings can and should be set manually to optimize work.
Go to your phone's settings, select Accounts and Sync, and click on your Google account. Make sure the switch opposite Contact is active. Finer setup is done via a web interface or a dedicated Google Contacts app that can be downloaded from Play Market. There's a "Currete and Manage" feature available that allows you to see all potential duplicates and combine them in a user-friendly interface.
| Parameter | Recommended value | Description |
|---|---|---|
| Source of conservation | New contacts are saved in the cloud | |
| Synchronization | Included. | Automatic data update |
| Display | Only Google. | Hiding local copies from your phone |
| Frequency | Automatically. | If there is an Internet connection |
It is critical to configure the contact display. In the Contacts app, click on the profile avatar or menu and select Settings" -> "Contacts to display. Just select your Google account. This will hide local copies from your phone and SIM-maps, leaving only a single, up-to-date database out of the cloud. Display filtering doesn't delete data, but makes the list clean and user-friendly.
☑️ Checking Google Settings
Clearing contacts with SIM-map
SIM-The map is a relic of the past in terms of keeping contacts, and it is the one that most often becomes the source of chaos in the Xiaomi Redmi Note 10 phone book. The character limit in the name on the SIM is limited, there is no way to add a photo, email or additional numbers, and when imported into the phone, each record often creates a new take of an existing cloud contact.
It is recommended to release completely SIM-To do this, open the Contacts app, go to the settings and select Import/Export Contacts. Select Import from SIM-maps" to transfer all numbers to your phone memory or immediately to your Google account. After successful import, be sure to select the "Delete from your phone" option. SIM-cards" or "clear SIM-map".
⚠️ Note: Removal of contacts with SIM-The card is irreversible unless you have pre-imported.Make sure all numbers are successfully saved to your phone or the cloud before clearing the SIM card.
After cleaning. SIM-card return to the settings of the display of contacts and uncheck the tick from the display of contacts from the SIM. It's guaranteed to remove visual noise. SIM-Digital hygiene involves storing contacts only in the cloud, making them accessible from any device and protecting them from loss when a phone breaks.
What to do if contacts are not imported?
Removing duplicates through Google’s web interface
The most effective way to clean up the whole thing is to use a computer and a web version of Google Contacts. The interface on the big screen allows you to rank the list faster, and Google tools work more accurately than the phone's built-in tools. This method is ideal if you have hundreds or thousands of contacts.
Go to contacts.google.com from your computer by logging into the same account as on Redmi Note 10. From the menu on the left, select "Combine and Correct" (or "Dublicates"). The system will automatically show a list of pairs of contacts that it considers to be the same. You can combine them one by one or use the "Combine all" button for mass processing.
- 🌐 Open your browser on PC and go to contacts.google.com.
- 🔍 In the menu on the left, select "Combine and correct".
- 👥 Review the proposed duplicates and confirm the merger.
- 🔄 Wait for sync: changes will appear on the phone.
Also available in the web interface is the Undo Changes feature, which allows you to roll back actions for up to 30 days, a safety mechanism that makes sure you don't lose data in a mass cleanup, and if something went wrong after combining on your phone, you can easily return everything as it was through the website.
💡
Google Contacts web interface is the most powerful tool for working with a phone book, allowing you to manage data faster and safer than through a mobile application.
Third-party applications for contact management
If standard methods don’t work well or MIUI functionality seems limited, you can turn to trusted third-party solutions from the Google Play Market. There are specialized client applications that use more complex algorithms to find not only full matches, but also partial matches.
One popular solution is Contacts Optimizer or Duplicate Contacts, which scans the database, finds records with the same numbers, even if the names are written differently (for example, with different abbreviations or a register of letters), but when using such programs, be careful: only provide access to contacts, not other data of the phone.
Another option is to use backup applications like Super Backup, which often have built-in duplicate management features. But remember, installing extra software can slow down the Xiaomi Redmi Note 10. Use these tools one-time to clean up, and then remove them, relying on standard system tools.
