How to remove double contacts on Xiaomi: the complete guide

The problem of duplicate phone book entries is one of the most common irritants for owners of Xiaomi, Redmi and Poco smartphones. After updating the system or transferring data from another device, users often find that one subscriber has two or even three numbers, and the contact list has turned into chaos. It is not just visual noise: duplicates take up extra space, interfere with the quick search for the right person and can cause errors when synchronizing with cloud services.

The reasons for this situation lie in the features of the shell. MIUI The system often automatically imports records from multiple sources: internal memory, SIM-If these sources have not been previously cleaned or combined, the phone perceives the same numbers as different entities, and fortunately, the developers have built-in tools to solve this problem that do not require the installation of third-party software.

In this guide, we will take a look at all the current methods of cleaning the phone book: you will learn how to use automatic unification functions, how to manually delete unnecessary records and how to configure synchronization so that the problem does not return.

Automatic combination of duplicates in MIUI and HyperOS

The fastest and safest way to clean up your messaging is to use the standard merging feature. Xiaomi’s standard Contacts app has a built-in algorithm that analyzes the list and finds repeating entries. Usually, the system offers to combine them automatically, but you can also manually start the process through the settings menu.

To do this, open the Contacts app and go to the Control section. Depending on the shell version, the path may be slightly different, but the logic remains the same. You need to find the item responsible for organizing the list, often hidden under the menu button or under the Contact Organization section.

Click on the "Joint Duplicates" (or "Mingle") button. The system will scan and show you a list of pairs that it considers to be the same. You can confirm the merger for all at once or select specific cases. This is especially useful if the subscriber has different numbers (mobile, home, work) and the erroneously system considers them different people.

⚠️ Before a mass merger, make sure that duplicate entries do not contain unique information that you have added manually (such as different email addresses or notes) as data may be lost or overwritten during a merger.

Once the process is complete, the system will report how many records have been deleted, an action that is irreversible through the standard "cancellation" function, so it's worth paying attention. Automated merger is the basic method that solves 90% of the problems with duplicates.

Manual cleaning and editing of individual records

Sometimes automation fails or misses obvious repetitions, especially if the numbers are written in different formats (e.g. +7 and 8), which requires manual cleaning, a more time-consuming method, but gives you complete control over the contents of the phone book.

Open a post you think is unnecessary. Click on the menu (three dots or the "More" button) and select "Delete." If you want to keep all numbers under one name, select the option "Merge" (Merge), the system will offer to choose from a list of similar subscribers, which allows you to create a single card with multiple phone numbers.

When you're manually editing, look for the "Name" and "Family" fields, and often duplicates are created because of typos or different word order (Ivan Petrov and Ivan Petrov), and the standard match-finding algorithm may not work in these cases.

• 📱 Open the contact and click "Change».
• ✂️ Select “Delete” for complete cleaning or “Combine” for merger.
• 💾 Click Save to fix changes in the database.

Regular manual checks are especially important for important contacts where room error is not acceptable.

Managing synchronization sources: Google and SIM

The main reason for the dual entries is the conflict between the local copy on the phone and the cloud storage. When you change your device or reset settings, Android suggests recovering data. SIM-Maps and pull them up from Google Account, there are duplicates.

To avoid this, you need to clearly identify the priority storage source, and it is best practice to store all contacts exclusively in the Google cloud, which ensures that they are safe when your phone breaks and allows you to easily sync data between devices. Local storage in the memory of the phone or on SIM-The map is now considered an outdated approach.

Check your display settings. In the Contacts app, click on the menu (usually three bars or dots) and select Contacts to Display. Make sure you select All Contacts or only your Google account. If you have any additional sources marked here (such as Phone or SIM 1), you can temporarily turn them off for verification.

You should also look at the sync settings. Go to Settings → Accounts and Sync → Google. Make sure the Contacts tick is active. If the sync is disabled, the phone will not know about changes made from the computer or other device and will create new local records.

Use of the Cleanup Tool in the Security App

Xiaomi smartphones have a powerful system application called Security that includes a cleaning module that can find not only garbage in the cache, but also duplicates in the phone book, an alternative way that sometimes works more efficiently than the built-in functions of the Contacts app itself.

Run the Security app and find the Cleanup or Tools section. Scroll down to the Special Opportunities or Contact Clearup section. The system will analyze the database and report on the problems found: empty contacts, duplicates and unnamed contacts.

Select the category "Duplicates of Contacts" and you'll see a list of groups that you can combine, and the advantage of this method is that it shows the preview of the cards, so you can visually verify the correct choice before you delete it.

It's a system table.

After selecting all groups, click the "Combine" or "Delete" button, which takes a few seconds to process, and is especially useful when duplicates have occurred after a failed firmware update or system failure.

Comparison of methods for removing duplicates

The choice of method depends on the scale of the problem and your confidence in the actions, and below is a table that helps you determine the best way to solve the problem for different situations.

As you can see from the table, the built-in tools are best for one-time cleaning, but setting up your Google account correctly is critical to keeping order in the long run.

⚠️ Warning: Do not use third-party apps from Play Market to clean contacts unless urgently needed.They often require excessive permissions and can disrupt the database structure MIUI.

Prevention: How to avoid doubles in the future

To prevent the double contact problem from returning, you need to change your smartphone usage habits. SIM-map. SIM-The card has a limited amount of memory and UTF-8 encoding is complete, which often leads to the appearance of “cracker” instead of names and the creation of new records during synchronization.

Configure the Contacts app so that your Google account is assigned to new entries by default. Go to the app settings and find the default account for new contacts. Select your email. Now all new numbers will go to the cloud immediately.

Periodically, every few months, check your contact list through the Google Contacts web interface. The web version has a more advanced “Combine and Fix” tool that often sees connections that are not visible on your mobile device, and you can massively delete empty or incorrect posts.

💡

Tip: Regularly export contacts to.vcf through the Google Contacts settings, which will create a recovery point in case of a serious system failure or loss of access to your account.

By following these simple rules, you can forget about the chaos in your phone book. A clean database speeds up your smartphone and makes communication more comfortable.

💡

The key to success is a single source of truth: Keep all contacts only in Google, and sync will work flawlessly on any device.
