Xiaomi smartphones are famous for their functionality, but sometimes users face an unpleasant problem: the phone book suddenly appears copies of the same numbers. SIM-Duplicates are not only visually annoying, but also create confusion when finding the right subscriber.
There are several proven methods to do this: owners of Redmi and Poco can use the built-in tools of the MIUI or HyperOS shell, as well as consult Google services or third-party software, the choice of the specific method depends on the version of the operating system and personal preferences of the user.
In this article, we will take a look at all the cleaning options available, learn how to combine the recordings manually, use automatic algorithms and prevent repetition in the future, and the right organization of contacts is the key to comfortable communication and efficient operation of your smartphone.
Reasons for the appearance of duplicates in the phone book
Synchronization is the main cause of contact chaos, and when you log in to your Google account on a new device, the system tries to combine data from the cloud with your phone's local memory, and if the algorithm doesn't work correctly, two or three separate entries are created instead of one contact with multiple numbers.
Another common scenario is the transfer of data from SIM-Older SIM cards often store information in a limited format, and when imported to a modern Xiaomi system can perceive each record as new, ignoring the existing analogues in the device’s memory.
⚠️ Attention: Frequent change of Google accounts or forced shutdown of sync service can lead to data desynchronization, which often provokes mass appearance of copies.
Duplicates also occur when using third-party messengers such as Viber or WhatsApp, which sometimes create their own phone book entries to correctly display avatars and statuses without checking for the original in the system.
Built-in cleaning tools in MIUI and HyperOS
Xiaomi’s shells come with useful contact management functionality that often goes unnoticed. The standard Contacts or Phone app has a duplicate merging feature. To activate it, you need to go to the app settings, usually available through a three-dot menu or gear.
The algorithm analyzes names and phone numbers, and if they match, the user is asked to combine them into a single card, which allows you to save all the numbers and email addresses of a person in one record, eliminating visual noise.
☑️ Checking the contact settings
It is worth noting that in different versions MIUI The menu layout may vary. In newer versions of HyperOS, this tool has become more prominent and often offers automatic cleaning immediately after the initial setting of the smartphone.
Removing duplicates through Google services
The most reliable way that works on any Android device, including Xiaomi, is to use the Google Contacts web interface, a method that is particularly effective as the changes apply to all devices associated with your account.
You can start by opening your browser on your smartphone or computer and going to Google's contact site. Once you log in, you'll see a menu on the left side of the screen that often displays a warning about duplicates, and the system will prompt you to "Combine and fix" the errors you find.
| Action. | Where to find out. | The result |
|---|---|---|
| Automatic merger | The left menu "Combine and Fix" | Quickly remove all explicit copies |
| Manual editing | Contact card → Change. | Point correction of errors |
| Data recovery | Cancel Changes menu | Return to 10, 20 or 30 days ago |
If the automatic tool didn't work, you can use the recovery function. Google Contacts has an option called "Cancel Changes" in its settings, which allows you to roll back the state of the phone book, which is useful if duplicates have appeared after recent sync.
What if Google doesn’t see the double?
Use of third-party clearing-house applications
When built-in tools are powerless, Google Play apps come to the rescue, and there are many tools specifically designed to clean phone books of garbage, and they use more flexible comparison algorithms that take into account the similarity of names even when there are typos.
One popular solution is Contacts Optimizer, or similar tools from trusted developers, which scans the database and suggests combining contacts that have the same phone numbers but different names, or vice versa.
⚠️ Warning: When installing third-party apps, be sure to check the permissions requested. do not give access to contacts to unverified low-ranking programs to avoid personal data leakage.
Once scanned, the app will give you a list of pairs or contact groups that you recommend combining, so that you can approve all the changes at once or view each group individually, which takes longer, but ensures that important data is not lost.
Manual card consolidation and editing
Automation sometimes gets it wrong, and you have to take matters into your own hands. Manual removal is the most time-consuming, but it's also the most accurate method, and it's necessary when the cards contain different data that you can't just leak without losing information.
To combine contacts on Xiaomi, open the desired entry, click on the menu (three dots) and select the option “Merge” or “Link contacts”. The system will suggest select a second contact from the list, which is a duplicate. After confirmation, all numbers and addresses will be collected in one card.
It's important to keep track of where the changes are going, and in the contact display settings, you can choose whether to show contacts from your phone, from Google, or all at once, and often duplicates are caused by mixing these display sources.
💡
Before you delete or merge your contacts, back up. In the Google Contacts app, this is done via the Export menu → saving the.vcf file to your device or to the cloud.
Preventing: How to Avoid Copies in the Future
To keep the problem from returning, you need to set up sync correctly. Make sure that the Google account settings on your Xiaomi check the box on only one contact source. Often users sync their contacts to SIM, phone and cloud at the same time, leading to conflicts.
It is recommended that you prioritize your Google Account source, in which case all new records will be saved to the cloud, not to your phone’s memory, which ensures that when you change your device or reset your phone book will recover to its perfect state.
Also, you should periodically check the settings of messenger apps. Telegram, Viber and WhatsApp you can turn off creating your own contacts or synchronizing with the phone book of the device, if you do not need this feature.
💡
The main rule of contact cleanliness is to use a single central account (Google) to store data and disable synchronization with the user. SIM-Cards after initial importation.
