Modern smartphones like the Xiaomi Redmi 8 have become an integral part of our lives, accumulating huge amounts of personal information. The phone book is one of the most important communication tools, but over time it has become “digital garbage”, duplicate records appear due to synchronization with different accounts, importing data from old devices or failures when saving numbers.
Not only is duplicate contact information annoying, it's also a real inconvenience when making calls. When the same name pops up multiple times and the call history is broken up into many small entries, finding the right caller becomes torture. Fortunately, the MIUI operating system on Redmi 8 has built-in tools to address this problem.
In this article, we will take a look at all the ways you can clean your phone book from unnecessary records, learn how to use regular smartphone functions, third-party apps and even cloud services to restore order, and the right organization of contacts is the key to fast communication and comfort when using your gadget.
Why do you see duplicates in the Redmi 8 phone book?
The main reason for the emergence of double entries is active data synchronization, users often link to a smartphone accounts Google, Mi Account, and profiles from social networks like Viber or WhatsApp, when the same person is listed in different sources with minimal differences in spelling of the name, the system perceives them as different people.
Another factor is the switch to a new phone, when you transfer data from an old device through a new phone. SIM-A card or Bluetooth is often automatically copied without checking for the existence of similar numbers.As a result, copies accumulate in the memory of the Xiaomi Redmi 8, which take up space and confuse the owner.
Sometimes it is the users who inattentively save the number again without checking the list, and duplicates can occur when manually entering numbers in different formats, for example, with and without a city code, the system does not always understand that +7 (999) 000-00-00 and 8 999 000 00 00 are the same subscriber.
⚠️ Note: Before starting a mass cleanup or merger of records, it is strongly recommended to create a backup of contacts.This will allow you to recover data in the event of an unexpected reset or synchronization error.
Understanding the causes helps prevent future chaos, checking synchronization sources regularly and typing data carefully minimizes the risk of contamination of the base, but if a problem has already occurred, you need to know how to get rid of it.
Use of the built-in linking function
The easiest and safest way to clean up the mess is to use the standard MIUI shell functionality. The standard Contacts app on Redmi 8 has a smart algorithm that automatically scans the database and suggests combining the matches found.
To start the procedure, you need to open the Contacts app and go to the settings menu, which is usually hidden under the icon of three dots or gears. Here you should find the item "Clean Duplicates" or "Combine Repeats." The system will offer a list of pairs that it considers to be the same.
You'll be asked to choose which entry to leave the main one, or to trust the system's automatic selection, and the merger process combines all the numbers and email addresses from different cards into one single entry, removing the extra shells.
☑️ Pre-unification checks
It's important to look carefully at the options that the system has, and sometimes the algorithm might go wrong and suggest that you combine the namesake with different numbers, and in those cases, you'd better skip the pair and check the data manually.
Manual deletion and editing of records
Automation doesn’t always work perfectly, especially if the names are written differently (like “Alexei” and “Lesha”).
To manually remove, open a specific contact card. At the bottom of the screen or in the menu (three dots), find the "Delete" button. Confirm the action in the pop-up window. This method is good for spot cleaning, when you need to remove 2-3 extra entries.
A more advanced method is editing, where you can open one of the duplicate cards, add the missing numbers from the second card, and then delete the second card, so you can save the entire history of the correspondence and calls tied to the number.
- 📱 Open the contact and click “Change».
- ➕ Add the second number in the "Add phone" field».
- 🗑️ Find the duplicate card and delete it completely.
- 💾 Save the changes to the main card.
This approach takes longer, but it ensures that all data is safe, and is especially relevant for important business contacts where losing even one additional number can be critical.
💡
When editing manually, use the “Company” or “Notes” field to mark the contact as verified so as not to get confused in the future.
Cleaning through Google Contacts (Web Interface)
The most powerful database tool is not in the phone itself, but in the cloud. Google Contacts has a great duplicate search and correction feature that often works more accurately than the utility built into the phone.
To access this method, you need to open your browser on your computer or in full mode on your smartphone and go to contacts.google.com. Log in to the same Google account that is used on your Redmi 8.
In the menu on the left, look for the Contact Management section (tool or gear icon) where the option “Combine and Fix” will be available, and the system will show you a list of contacts it believes are duplicates and suggest combining them with a single click.
| Method | Difficulty | Speed. | Risk of error |
|---|---|---|---|
| Built-in MIUI function | Low. | Tall. | Medium. |
| Google Contacts (Web) | Medium | Very high. | Low. |
| Third-party annexes | Tall. | Medium | High-pitched |
| Manual removal | Tall. | Low. | Minimum |
After performing operations in the cloud, you need to go back to the contact settings on your smartphone and force the data to sync, usually through the Accounts menu in your phone settings or directly in the contact app.
💡
Google Contact Sync is the most reliable way to do this, as changes apply to all devices associated with your account.
Third-party applications for cleaning duplicates
If Xiaomi’s regular funds and Google services failed, you can turn to the help of specialized software. In the Play Market, there are many applications-cliners that are sharpened for removing duplicates, but their choice should be approached with caution.
Popular programs like Duplicate Contacts or Clearer scan the database and offer flexible filtering settings, so they can search for duplicates not just by number, but by name, email address, or even photo, and this allows you to find hidden copies that other methods miss.
⚠️ Note: By installing third-party contact apps, you give them access to your personal information. Choose only proven programs with high ratings and a large number of reviews to avoid data leakage.
Once you install the application, run the scan. The program will give you a list of problems you've found. You can choose to automatically delete or manually go through the list. Once the cliner is complete, remember to delete the application itself so that it doesn't consume system resources in the background.
- 🔍 Download a high-ranking app from Google Play.
- 🛡️ Provide the necessary permissions to access contacts.
- ⚙️ Start a deep database scan.
- ✅ Confirm the removal or merging of found duplicates.
The use of third-party software is justified in difficult cases, when the contact database is heavily contaminated and contains hundreds of incorrect records of different structures.
Prevention and Synchronization Configurement
To prevent the problem of repetitive contacts from returning, it is important to properly configure the save system. On Xiaomi Redmi 8, the default can be saving on the device. SIM-card or phone memory, which often leads to desynchronization.
You should set your Google Priority Account. To do this, go to your phone settings, select Accounts and Sync, find your Google account and make sure the checkmark opposite Contacts is active. Also, in the Contacts app settings, you can select Contacts to Display and Contacts to Save.
Set a rule: all new numbers are saved only to the cloud, which ensures that if you lose or replace your phone, your entire phone book will recover automatically, without the need for manual transfer and the risk of creating copies.
It's also useful to do a monthly review through Google's web interface, which takes a couple of minutes, but keeps the database clean, and regularity is the key to order in the digital space.
