The problem of duplicate phone book entries is a classic smartphone disease that is particularly common after switching from one device to another or resetting settings. Owners of the popular Xiaomi Redmi Note 8 Pro are no exception: when migrating data from Android or iOS, and when you enable synchronization with multiple cloud services at the same time, the system can create copies of the same numbers, not only visually cluttering the interface, but also creates real inconvenience when calling, as incoming calls can display different names for a single subscriber.
This MIUI shell problem doesn’t require third-party software or complex code manipulation. Built-in algorithms allow you to effectively manage your contact list by combining duplicate records or manually deleting them. Understanding the logic of your address book will help you get rid of clutter in your call list forever and ensure that messengers, who often use the phone book to identify users, work correctly.
In this article, we will take a closer look at all the cleanup options available, from automatic merges to deep setup of Google and Mi accounts. You will learn how to prevent duplicates from appearing in the future and how to properly organize the storage of numbers so that your phone book always remains clean and structured.
Reasons for the appearance of duplicates in the address book
The main reason for the mess is the disconnect between the smartphone’s local memory and cloud storage. When you set up the new Redmi Note 8 Pro, the system often suggests recovering data from Google’s backup as well as from the Mi Cloud. If one source has a number written as “+7999...” and another source says “8999...”, the algorithm perceives them as different objects and creates two separate cards.
Another factor is the use of SIM-Older phones often saved numbers directly to a SIM card chip, which has a limited data format and does not support complex names or additional fields. When importing such records into a modern Android smartphone, the system can create duplicates for those contacts that have already been stored in the memory of the phone or account.
⚠️ Note: Before starting a mass deletion or merger, it is strongly recommended to back up your contacts via a Google account or export them to a.vcf file.
Duplication can also occur when using third-party call or messenger applications that have their own databases and try to sync them with the system ledger. For example, some corporate clients or applications from carriers can automatically add their copies of contacts for easy integration of services.
Use of the built-in contact merging function
The fastest and safest way to clean up your mess is to use a regular MIUI tool that automatically finds matches, which analyzes names and phone numbers, suggesting that you combine cards that are likely to belong to one person, a method ideal for initial cleaning after you buy a device.
To start the process, open the standard Contacts app and go to the settings menu, which is usually hidden behind three dots or stripes in the corner of the screen. Find Contact Clear or Tools where the merger option will be available. The algorithm will prompt you to view pairs of takes and confirm their combination, or perform this automatically in the background.
Importantly, the merging function works most effectively when the contacts have the same number recording format. If one card has an international number and another city number, the system may not recognize the duplicate, in which cases manual intervention or preliminary normalization of the number format will be required.
☑️ Pre-merger check
Manual deletion and editing of records
Automation doesn’t always work perfectly, especially if the names are written differently (like Ivan Ivanov and Ivanov I.). In such situations, the Xiaomi Redmi Note 8 Pro has to resort to manual editing. It’s a more time-consuming process, but it allows you to achieve absolute accuracy and remove the duplicates that the system missed.
Open the contact card you think is the primary one, and click the edit button. At the bottom of the screen or in the action menu, the "Contact Connect" or "Connect" option is often available. Once you select this item, you can mark other cards from the same person, and the system will combine all the information (photo, email, addresses) into one entry.
If you're talking about full copies that don't carry unique information, you'd better just delete them. Select an unnecessary entry, call a menu, and select "Delete." Be careful when removing contacts saved on the site. SIM-the card, as its restoration may be difficult without prior export.
💡
When manually removing duplicates, sort the list by name – this will help you find repeating entries that go in a row faster.
Syncing Google and Mi Cloud
The key to preventing duplicates in the future lies in properly configuring sync sources: Xiaomi smartphones have two clouds activated by default: Google and Mi Cloud. If both services try to keep the same contact at the same time, there may be a version conflict and subsequent duplication.
It is recommended to choose one main source of truth. For most users, a Google account is the best option, as it provides cross-platform and brand independence from the phone. To set this up, go to Settings → Accounts and Sync. Here you will see a list of all the services connected.
| Parameter | Google Account | Mi Account. | Telephone (Localno) |
|---|---|---|---|
| Reliability | Tall. | Medium | Low (dumping when broken) |
| Access to PC | Available (contacts.google.com) | Aye (i.mi.com) | No. |
| The risk of doubles | Minimum | Medium. | High on changing the phone |
| Recommendation | Main source | Additional | Don't use |
In sync settings, make sure that the Contacts checkbox is only activated for the selected primary account. For a secondary account, it is better to turn off contact sync, leaving only photos, notes or other data active to avoid recording conflicts.
⚠️ Note: Disabling sync does not delete data already stored, but stops updating it in the cloud.
Cleaning of contacts saved on SIM-map
Contacts stored on SIM-The Redmi Note 8 Pro often displays these records separately or mixes them with the main ones, creating visual noise. The best practice is to transfer all the numbers to the phone or cloud. SIM-Use the card only for identification in the network.
To manage your SIM records, open the Contacts app, click on the settings menu and select Import/Export Contacts. SIM-After importing all the numbers will appear in the phone memory, where they can be fully worked with: add photos, email and addresses.
Why not keep your contacts on SIM?
After successful import and data integrity check, it is recommended to clean the data itself. SIM-In the same menu, select "Delete contacts from the Import / Export" SIM-This action will protect you from accidentally re-importing old records the next time you change your device.
Using Google Contacts for Deep Cleaning
The most powerful tool to combat duplicates is Google Contacts web interface. Because Android is deeply integrated with Google's ecosystem, changes made through the browser on your computer will instantly affect your Xiaomi Redmi Note 8 Pro after synchronization. This method is especially convenient for mass processing of a large list.
Go to contacts.google.com from your computer or in full mode on your smartphone. In the left menu bar, find the "Combine and Fix" section. Google will automatically offer a list of duplicates with the "Combine All" button. This action will take a couple of seconds and clear the list more efficiently than any mobile application.
In addition, the web interface allows you to filter contacts by groups and tags, you can quickly find all entries without a name or with incomplete data and delete them, and there is a feature called Undo changes, which allows you to roll back the state of the phone book by 30 days, which is useful if you accidentally deleted the excess.

Google Contacts web interface is the most reliable way to clean up your address book, as it works with a “cloud master copy” of your address book.
