Owners of modern smartphones such as Xiaomi Redmi Note 10S, Often, they face a common problem: when you move data from an old device or restore it from cloud storage, a lot of duplicates appear in the phone book. SIM-Instead of having one person, you can have three or four records with the same name, but different numbers or none, and this confusion is not only visually annoying, but also makes it difficult to quickly find the right caller in an emergency.
Fortunately, the MIUI 12.5 or newer operating system installed on your device offers built-in tools to solve this problem without having to download third-party software. Contact pairing is the process of merging multiple cards into one full-fledged record, allowing you to save all important numbers and email addresses under one name. In this article, we will detail an algorithm of actions that will help you bring perfect order to your address book in just a few minutes.
Before you start manually cleaning, it's worth noting that automatic sync systems sometimes make mistakes and create copies where they shouldn't be, such as when you connect a new account or after you reset the settings to factory. Understanding the cause of duplicates will help you avoid such situations in the future. Redmi Note 10S has a fairly powerful processor and optimized interface, so the merger procedure is fast and does not cause system freezes.
Preparation of a telephone book before editing
Before you start actively merging, you need to make sure you're working on the current list and you see all the hidden numbers. Often duplicates are hiding in different display groups. Open the Contacts app and go to the display settings. Make sure you tick the box against All Contacts, which will allow the system to show you a complete picture of what's stored in the device's memory.
It's also important to check which storage you're working with. SIM-In your phone, in your phone's internal memory, or in your Google account, for a comfortable experience and the ability to use all the features of a smart merger, the best thing to do is to have the basic data in the Google Contacts cloud. If your numbers are stored locally on your device, it is recommended to export or sync them in advance so as not to lose important information in the event of an unforeseen failure.
If one contact is recorded as Ivan Ivanov and the other as Ivanov Ivanov, the automatic merger may not work correctly and you will have to combine them manually. Standardizing the names before starting the process will save you time. Also, make sure you have a stable Internet connection if you plan to sync the changes to Google servers in real time.
💡
Before starting mass editing, back up your contacts through the Import/Export menu so that in case of an error, everything can be returned in a couple of seconds.
Automatic merger of duplicates in the Contacts app
The fastest way to get your Redmi Note 10S in order is to use the built-in auto-union feature. The system analyzes the list itself, finds similar names and numbers, and suggests combining them. To start this process, open the Contacts app, click on the three dots in the upper right corner (or menu button), and select Contact Organization or Contact Management.
In the menu that opens, find the option to "Combine Repeated Contacts." The system will start a database scan. This process can take from a few seconds to a minute, depending on the number of entries in your phone book. Once the scan is complete, MIUI will show you a list of duplicates found. You will not need to confirm each action separately if you trust the algorithms, but you should check the pairs suggested.
- 🔍 Click on the “Combine All” button so that the system itself drains the pairs found.
- 👀 Check the list carefully if you are afraid of losing unique numbers.
- ✅ Confirm the action, and the system will create a single card for each subscriber.
Once the procedure is complete, the contact list will be significantly reduced, and all the numbers that were duplicated will remain in the cards. Automated merger works quite effectively in 90% of cases, but sometimes can miss contacts with slightly different spelling of the name.
Manually combining contacts by steps
If the automation failed or you want to have full control of the process, you can combine contacts manually. This method is especially useful when you need to connect cards that the system does not consider duplicates (for example, different names of the same person), open the card of one of the contacts that you want to leave the main one. At the bottom of the screen or in the menu (three dots), find the "Combine" or "Connect" button.
Once you click, the system will suggest you to select a second contact from the list. You can search by entering your last name or phone number. Once you select the right entry, confirm the action. Now, one card will display all the numbers and mailing addresses from both source records. Manual combination allows you to create complex profiles where multiple work and personal numbers correspond to one name.
☑️ Pre-unification checks
Note that manual merges give priority to the card you opened first, that the photo, name and primary address will be taken from that card, and the data from the second card will simply be added with a list. If you make a mistake and combine the wrong contacts, you can cancel the operation, but only until you sync with the cloud, so be careful when choosing the main card.
⚠️ Note: When manually combining contacts with SIM-From maps and from the Google cloud, the system can suggest saving the result in only one place: Select a Google account so that data is not lost when replacing the SIM card.
Using Google Contacts to Manage Duties
The most reliable way to manage a contact book on the Xiaomi Redmi Note 10S is to use the native Google Contacts app, which is often pre-installed on a smartphone or available in the Play Market. Its algorithms work more accurately than standard MIUI tools, because they use Google databases. Open the application, go to the Fix & manage tab.
Here you'll see the option "Combine and Fix"; Google will offer to combine similar contacts or contacts with the same numbers, and the peculiarity of this method is that the changes apply immediately to all devices where you log in, which ensures that order is not only on the phone, but also on the tablet or in the web version.
| Function | Standard MIUI Contacts | Google Contacts |
|---|---|---|
| Automatic merger | Basic, by name. | Smart, by numbers and names. |
| Synchronization | Only when on | Instant, background. |
| Recovery | Limited. | Up to 30 days ago |
| Interface. | Depends on the topic. | Standard Material Design |
Google also makes it easy to roll back changes, and if you accidentally delete an important number or combine cards incorrectly during the cleaning process, the app's settings include "Cancel Changes," which allows you to go back to the state of the phone book by 10 minutes, an hour, or even 30 days, the only guarantee that your data is completely secure when you edit it in bulk.
Resolving synchronization and display problems
Sometimes users are faced with a situation where after combining contacts again appear in the form of duplicates. This indicates a sync problem. On Redmi Note 10S, you need to check your account settings. Go to Settings → Accounts and Sync → Google. Make sure that the slider opposite the Contacts item is active.
If sync is enabled but takes are back, try clearing the Contacts and Google Play Services cache. Go to Settings → Apps → All apps, find the service you want, and click Clear Data or Clear Cache. Don’t worry, it won’t delete your numbers stored in the cloud, but it will restart the process of downloading them to your device.
- 🔄 Check the status of the Internet connection (Wi-Fi or mobile network).
- 🔐 Make sure your Google account does not run out of storage space.
- 📱 Reboot your smartphone after all mergers.
Another reason could be the conflict between Mi Cloud and Google synchronization: If you use both services at the same time, they can "twist" old versions of contacts. It is recommended to choose one main source of truth, preferably Google, and disable contact synchronization in Mi Cloud to avoid cyclical duplications.
