The problem of duplicate records in the phone book is a classic situation for users of Xiaomi smartphones who actively use the Viber messenger. When you see the same subscriber appearing twice or even three times, it's not only visually annoying, it's also difficult to find the right number in an emergency. SIM-Map, internal phone memory and Google account.
The Android operating system, which is the shell of MIUI or HyperOS, has a mechanism for aggregating contacts, which is designed to combine records from different sources into one card, but sometimes this process fails. Instead of one name, you get a list of the same records with different source icons, and solving this problem requires a systematic approach and understanding how exactly the data is stored on your device.
In this article, we will discuss all effective methods of cleaning the list of calls from garbage, you will learn how to properly configure synchronization, use built-in cleaning tools and third-party utilities if standard methods do not help.
Reasons for the appearance of contacts doubles in Viber
Before you start deleting, you need to understand the nature of the errors.Duplication often occurs after transferring data from an old device or restoring a backup. SIM-cards as two different items if their identifiers do not match when imported.
Another common reason is that you have multiple Google accounts on your device. If you've ever added email for work or school and enabled contact sync, your phone could copy your existing database to a new account. In the Viber app, this is shown as doubling the list, as the messenger scans all available address book sources.
- 🔄 Synchronization conflict between local phone memory and Google cloud storage.
- 📱 Import of records SIM-maps without first checking the existing database.
- 📧 Having multiple active Google profiles with contact synchronization enabled.
It’s also worth noting that some third-party apps, such as social media or instant messengers, can create their own phonebook entries for quick access. Viber is no exception, but more often than not it just displays what’s already in the system.
⚠️ Attention: Before you start any manipulation of the phone book, you are strongly advised to make a backup copy. Even if you are confident in your actions, accidentally deleting the desired number can be a nuisance.
Preparing for cleaning the phone book
The first step is to create a restore point, and in the Xiaomi ecosystem, this is done through a Mi or Google account, which is a critical step, because the contact pooling tools work automatically and can mistakenly combine namesakes with different numbers.
Check which account is the primary one for keeping contacts. This is usually the Gmail that was added first when you set up your phone, and that's where we're going to save the clean version of the list, and make sure you have a stable Internet connection to work with cloud services.
☑️ Preparation for contact cleaning
If you use it SIM-It's recommended that you export it to your phone first, and then you work with the combination. Storing contacts on a SIM is an outdated method that limits the number of characters in your name and doesn't allow you to add photos or extra numbers.
Use of built-in Google Contacts features
The most reliable way to fix the problem is to use Google’s native app, which is pre-installed on all Xiaomi smartphones, which has a powerful merger algorithm that analyzes names and phone numbers, suggesting that similar entries be combined.
Open the Contacts app (usually a blue icon with a human silhouette). In the bottom menu or sidebar, find the Fix & manage tab, where the system automatically analyzes the database and gives a list of potential duplicates.
Click on "Connect" and you'll see a list of pairs or groups of records that the system thinks are the same. Carefully look at them: if the names and numbers match, feel free to press "Connect" button. If the system suggests connecting different people with similar names, skip this step.
| Action. | Where to find out. | The result |
|---|---|---|
| Automatic merger | Contacts → Correct and Manage | Deletion of exact copies |
| Manual association | Contact Selection → Menu → Combining | Controlled merger |
| Export to file | Settings → Exports | Creating a backup copy.vcf |
Once the procedure is complete, restart the smartphone, which is necessary for the MIUI system to completely update the phonebook index and transmit the correct data to Viber. Often the messenger caches the old list, and the reboot helps refresh the display.
💡
If the automatic association does not work, try in the Google Contacts on your computer app (contacts.google.com) select several contacts through checkboxes and click the "Merge" button in the top menu.
Configure the display of contacts in MIUI
Sometimes duplicates are not technical errors, but only a feature of the display. The MIUI and HyperOS shells have filtering settings that can show contacts from all sources separately, even if they are combined in the database.
Go to Contacts, click three dots in the corner, and select Settings. Find Display Contacts. You can select a specific account or SIM-If you have All Contacts, try switching to your primary Google account.
Also worth checking is Viber's settings. Inside the app, go to Settings → Privacy → Contacts. Press the update or sync button if available. This will cause the messenger to read the phone's address book again.
- 👁️ Checking display filters in the Phone and Contacts application.
- 🔁 Forced synchronization within Viber settings.
- 🗑️ Clearing the cache of the application Contacts through Android settings.
In some versions of Xiaomi firmware, there is a bug when contacts with the SIM-Maps duplicate Google records, even if you don't allow the SIM to be displayed, and then temporary retrieval helps. SIM-cards, cache cleaning and re-insertion.
⚠️ Warning: Don't manually delete contacts one by one if there are hundreds. You may accidentally delete a unique record thinking it's a copy. Use only mass-mergering tools.
Cleaning through Google’s web interface
The most accurate and safe cleaning can be done from a computer; the web version of Google Contacts provides more flexible management tools than a mobile app, which is especially useful if the phone interface is slow or freezes.
Go to contacts.google.com and log in to the same account used on Xiaomi. On the left side of the screen, find the control menu. There will be a section called "Consolidate and fix." The system will offer you the options for the merger.
The advantage of the web version is that you can choose from it, because on the big screen, you can see the differences in numbers or names, and you can select groups of contacts using Ctrl or Shift, and you can use the actions.
What if the contacts are not synchronized after cleaning?
Once you've completed all your computer operations, grab your phone. Make sure it's connected to Wi-Fi. Open your Google account settings and tap Sync. The process can take anywhere from 1 to 5 minutes depending on the size of the phone book.
Third-party applications for removing duplicates
If the built-in tools Xiaomi and Google failed, you can turn to specialized software. in the Play Market there are many utilities, but be careful: they require access to your personal data, so choose only proven solutions with high ratings.
A popular and safe option is Contacts+ or Duplicate Contacts, which scans a database of complex algorithms, finding not only full copies, but also entries with small typos in names, which helps to remove the "garbage" that has been created over the years of using a smartphone.
When using these programs, keep a close eye on the process. Don't agree to automatically merge all the matches you find without checking. It's better to spend time manually monitoring than then restoring the tangled numbers of friends and colleagues.
- 🛡️ Choose applications with more than 1 million installations.
- 📝 Read the latest user reviews before installing.
- 🚫 Avoid applications that require extra permissions (access to the camera, microphone).
After using a third-party cleaner, it is recommended to check sync with Google again. Often these applications work with a local base, and the changes need to be pushed to the cloud so that they appear in Viber on other devices.
💡
The most effective method is a combination of manual verification through Google’s web interface and automatic merger through built-in MIUI tools.
