Xiaomi smartphone owners often face a situation where repeated entries appear in the phone book, this happens after switching from one device to another, recovering data from cloud storage or syncing with the phone. SIM-On the Redmi Note 10 model, the shell is controlled. MIUI This process may seem confusing due to the interface.
Duplicates not only clutter up the list, but also create confusion when calls are sent to different names or incorrect avatars are displayed. Fortunately, the system offers built-in tools for automatic and manual merging of records. Understanding the logic of how the address book works will help you clean up your order in minutes.
In this article, we will take a look at all the available methods for cleaning the subscriber list, how to use automated algorithms, how to manually link cards, and what to do if standard methods do not work, and we will also discuss synchronization with a Google account, since this is where the master copy of your data is most often stored.
Reasons for the appearance of duplicates in the phone book
The appearance of duplicate records is not a system bug, but a feature of modern operating systems that aggregate data from different sources. When you first turn on the Redmi Note 10, the phone suggests that you restore data. SIM-In the memory of the phone and in the Google cloud, the system imports them all as separate entities.
Another common reason is to change the carrier or phone, and when you move your contacts over Bluetooth or special migrant apps, the formatting of the data can be disrupted. +7 999 000-00-00 and 89990000000 The system perceives them as different, even if they belong to the same person.
⚠️ Note: Before starting a mass deletion or merger of records, it is strongly recommended to create a backup copy. Misconception may result in the loss of important notes or second numbers attached to the card.
It is also worth considering the specifics of the shell work MIUI. It has its own add-on over the standard android contact interface, and sometimes the phone or contact cache can contain outdated data that visually displays as duplicates, even if it is no longer in the database.
Understanding the source of the duplicates will help you analyze where the contact is maintained, and it allows you to see the link to a particular account, and understanding this mechanism is critical to the proper management of data.
Automatic connection of contacts in MIUI
The easiest and safest way to clean up your messaging is to use the built-in merging feature. Xiaomi's algorithms are smart enough to recognize the same names and numbers, even if they're written in different formats.
Open the standard Contacts app or go through the Phone menu to the Contacts tab. In the upper right corner or in the settings menu (three dots or gear), you need to find Contacts Organization. In some versions of MIUI, this section may be called Contact Management.
Inside this menu, you'll see the option "Combine Duplicates," which will scan the database and suggest a list of pairs or groups of records that it considers to be the same, and you'll only have to confirm the action, which usually takes no more than 30 seconds, even if there are thousands of records.
💡
If the system does not find duplicates automatically, try first to clear the cache of the Contacts app through your phone settings, and then repeat the procedure.
Importantly, automatic linking works best when contacts are synchronized with a single account, and if some numbers are local to the device and some are in the cloud, the algorithm may not see the connections between them.
Manual merging of subscriber cards
Automation isn't always perfect. There are times when you need to combine contacts with different names (like "Mama" and "Mama Worker") or when the system doesn't recognize the take. In such cases, the Redmi Note 10 has a manual linking feature.
To do this, open a contact card. In the action menu (usually three dots in the corner), select the option "Combine with another", and a list of all your records will open where you can find the second caller, and after the selection, a merger will occur: all numbers, email addresses and photos will be combined into one card.
- 📱 Open the Contacts app on the home screen.
- 🔍 Find and choose the contact you want to leave the main one.
- ⚙️ Click on the menu (three dots) and select "Merge with another".
- ✅ Find the duplicate entry in the list and confirm the selection.
This is especially useful when a person has changed their number, but you want to keep your email and call history in one card, and manually combining it allows you to fix errors that have arisen when importing files from VCard.
After manual operation, the data may be updated for a while in the interface. If you do not see changes immediately, try rebooting your smartphone or switching to another type of list (for example, from “Phone Only” to “All Contacts”).
☑️ Pre-merger check
Working with Google Account and Synchronization
The foundation of the Android phonebook is the Google account, which is the master source of truth, and if you combine contacts in the Google Contacts cloud, the changes automatically will be pulled to your Redmi Note 10, regardless of the version of MIUI.
Go to contacts.google.com from your computer or your phone browser. In the left menu bar, you often see a notification of duplicates you find with the "Combine and Fix" button, which is the most reliable way, because it works at the server level.
If you don't have an automatic offer, you can use the "Combine and Fix" tool on the left menu, Google will offer to combine contacts with the same names or numbers.-force synchronize.
For forced sync, go to Settings → Accounts and Sync → Google. Make sure the tick opposite Contacts is active, then click three dots in the corner and select Sync.
⚠️ Note: When syncing with Google, cloud data is the priority. If you manually change the contact on your phone but are not connected to the network, the next time you connect, cloud data can overwrite local changes.
Using cloud storage also makes it easy to recover the contact list in case of a device loss or reset. SIM-This guarantee does not give and limits the functionality (for example, you can not add a photo or a second email).
What to do if your contacts are not synchronized?
Import and export: elimination of format conflicts
Often duplicates occur when you transfer contacts from old phones..vcf file formats can be interpreted differently by different versions of Android. If you imported contacts and got porridge, the best solution is to export completely and re-import with filtering.
First, export all contacts to.vcf. Then delete all contacts from the phone (making sure the copy is in the file or cloud). After that, import the file again. Modern versions of MIUI often offer the option of "Do not import duplicates" when importing.
When working with SIM-The problem is more complicated than the map, and the phone cards have limited memory and do not support complex fields. SIM New records are created rather than old ones being updated.
It is recommended to always keep a master copy in Google, and SIM-Use the card only as a transport carrier when changing the operator, immediately copying the data to the cloud and clearing the map.
Comparison of contact cleaning methods
The choice of method depends on the number of takes and the source of their occurrence. Below is a table that will help determine the best way to solve the problem for your case.
| Method | Speed. | Reliability | It's best suited for |
|---|---|---|---|
| Automatic merger in MIUI | Tall. | Medium | Small take with the same names |
| Google Contacts (Web) | Medium | Very high. | Global cleaning and working with different devices |
| Manual association | Low. | Tall. | A spot correction of complex cases |
| Exports/Imports of VCF | Low. | Medium | Migration from very old phones |
As you can see from the table, for most Redmi Note 10 users, the best solution is a combination of automatic in-shell merger and periodic verification through Google’s web interface, which provides a balance between usability and data security.
Regular checks are not to be neglected, and once every six months, it makes sense to look at the list for obvious duplicates that may have slipped through the system's filters.
💡
The most effective way to avoid duplicates in the future is to keep contacts exclusively in your Google account and disable saving on your account. SIM-card and local memory of the phone.
