The modern smartphone becomes the repository of your entire social life, and when duplicates start appearing in the phone book, it becomes a real problem. You get a call from an important customer or relative, and you get three different names for the same number on the screen, or worse, you can't find the contact you want because it's lost among a dozen copies. Owners of Xiaomi, Redmi and Poco devices often face this after a change. SIM-map, switch from another phone or sync failure with Google account.
Fortunately, the Android operating system, which is operated by the MIUI shell or HyperOS, has built-in mechanisms to solve this problem. You don't need to download third-party applications that can request unnecessary permissions and overload the system. Standard tools allow you not only to combine records, but also to prevent them from appearing in the future. In this article, we will discuss in detail all ways to clean the phone book from garbage.
Understanding the causes of duplicates will help you avoid this problem in the future, most often because contacts are stored simultaneously in memory. SIM-And then the system maps them as different entities, and sometimes the user accidentally creates a new record instead of editing the old one, and the conflict of data sources is the main technical reason that we're going to be eliminating.
Automatic connection through contact settings
The easiest and fastest way to clean up the messaging is to use the built-in merging feature. On Xiaomi smartphones, this tool is often hidden in the contact management menu, but it works quite effectively for basic cleaning.
To get started, you need to open the standard Contacts app, which is the default app on your device. Don't confuse it with Phone, although the functionality often overlaps. In the upper right corner of the screen, you'll see a three-dot icon or a gear that indicates the settings menu.
In the options list that opens, find the line "Combine Repeated Contacts." The system will run a database scan. If duplicates are found, a list of pairs or groups of records that can be combined will appear on the screen, you can confirm the merger for each group separately or select the "Combine All" option to perform the operation en masse.
⚠️ Note: Before mass consolidation, make sure that the combined records do not contain unique data that you want to keep separately (e.g., different work and personal numbers tied to the same name but recorded with errors.
Once the procedure is complete, the system will report the number of deleted duplicates, your phone book should look cleaner, but the automation is not always perfect: it can skip records where numbers are written in different formats (for example, +7 and 8, or with spaces and without), in which case manual intervention will be required.
Manual merging of records in the Contacts app
When the automatic tools fail, manual editing comes to the rescue, and it takes longer, but it gives you complete control over the outcome, and you decide which fields are combined and which are deleted, and this is especially true if you have contacts with the same names but different numbers that the system doesn't consider to be duplicates.
To combine the recordings manually, open the contact you want to leave the main one. Click on the "Change" button (usually a pencil or text at the bottom of the screen). Scroll down to the very end of the field list. There you will find the option "Connect" or "Combine with another contact".
Once you select this option, you'll open a list of all your records, find a duplicate contact and click on it, and you'll merge, and all the numbers, email addresses and addresses from the second record will be added to the first, and the second record will be deleted as a separate unit.
- 📱 Open the Contacts app and select the required entry.
- ✏️ Press the edit button and scroll down to the "Connect" item".
- 🔗 Select a duplicate contact from the list.
- 💾 Click Save to apply changes and delete the take.
If you have a lot of these pairs, it can take a lot of time, and in this case, it's useful to use a display filter, and in the contact display settings, you can choose to only show contacts with the same number of times. SIM-Maps or only from a Google account, making it easier to find discrepancies.
☑️ Checking before manual association
Removing duplicates through Google account
The most reliable way to clean up is at the cloud level, not just at the phone level. If your contacts are synced with Google Contacts, you can use a powerful web interface to manage them, which is especially handy if duplicates have appeared after you moved to a new phone or recovered from a backup.
Go from your computer or directly from your phone’s browser to contacts.google.com. Sign in with the same account your Xiaomi uses. On the left menu, find the “Merge & fix” section. Google automatically analyzes the database and offers contact groups for merger.
The advantage of this method is that the changes will apply to all the devices that log in to that account, so you don't have to clean the phone book on each gadget separately, and Google often finds connections that the local Android algorithm misses, such as contacts with slightly different names but the same email addresses.
⚠️ Note: Changes to Google Contacts sync instantly. If you accidentally combine the wrong contacts, you have 30 days to restore the previous version through the "Cancel Changes" feature in the settings of the web version.
After cleaning in the cloud, take your phone and go to Settings → Accounts and Sync → Google. Make sure the Contacts slider is active, and press the Sync button (usually three dots in the corner -> Sync).
What to do if your contacts are not synchronized?
Working with contacts on SIM-card and phone memory
One of the most common causes of chaos in the phone book is the storage of data in different places. SIM-The map (to keep them on when you change the phone), the other ones in the memory of the device, the third ones in the cloud.
To solve this problem radically, it is recommended to move all contacts to a single repository - a Google account. To do this, go to the Contacts app, select the settings menu and find the item "Import / export". SIM-maps and specify your Google account with the target storage.
After successful transfer, you can delete the contacts from the SIM-maps to avoid confusion. In the same import/export menu, select "Delete contacts from the SIM-Delete all contacts from your phone (if you are sure that the cloud copy is complete) will provide a single point of truth for all your data.
| Storage area | Advantages | Deficiencies | Recommendation |
|---|---|---|---|
| Google Account | Synchronization, recovery, search | You need the Internet for the initial download | Main vault |
| Phone memory | It works without the internet, fast. | Disappears when broken or dumped | Not recommended |
| SIM-map | Portability between telephones | Little space, no photo, only 1 room. | Use only for temporary storage |
After transferring the data, make sure to set up the display. In the Contacts app, click on three dots (menu) and select Contacts to Display. Check only against your Google account. This will hide all local copies and duplicates from your Google account. SIM-map.
💡
A single storage in a Google account is the key to a clean phone book without duplicates and the risk of data loss when changing the device.
Display setting and list filtering
Sometimes duplicates are just an illusion caused by the wrong filtering settings, like you can see contacts from all the connected accounts (WhatsApp, Viber, Telegram, Skype) that create virtual copies of the posts with messengers attached. These are not real duplicates, but they clutter the list.
In the display settings (Settings → Contact Filter), you can flexibly configure who to show, you can leave only those contacts with a phone number, or hide contacts without names, which helps to visually clear the list, even if the records are not technically combined.
You also need to look at sorting, and if contacts are sorted by name, duplicates with the same name will be next to each other, making it easier to find them, if the date of addition makes it harder to find repeats, and you can change the order in the app settings menu by selecting "Sort".
- 🔍 Use a name or number search to quickly find groups of take.
- 👁️ Turn on the display of contacts with numbers only to remove empty entries from social networks.
- 📇 Check the Favorites list regularly for duplicates, as they are often copied there.
Remember that messengers can create their own records. If you delete a contact from your phone book, it can disappear from Viber, but it's better not to risk backing up first. The integration of services into Android is deep, and changes in one place affect others.
Preventing the appearance of duplicates in the future
To keep the problem from coming back, it's important to change your smartphone usage habits. The main recommendation is to always choose a Google account when you save a new number. When you call someone or get a message, Android suggests saving the number; carefully look at where it is saved.
Regularly audit your contacts. Every six months, run a checkup through Google's web interface or Xiaomi's built-in tools. This takes a couple of minutes, but saves you hours of nerves in the future. It's also helpful to delete old, unnecessary numbers that you no longer use.
If you change often SIM-Maps or phones, use the export function to.vcf. Backup before any major operation, which will allow you to roll back if the unification process goes wrong and you lose important data.
⚠️ Note: When using third-party apps to clean up duplicates from the Play Market store, read permissions carefully.Many require full access to your contacts and may share your phone base with third parties for advertising.
Following these simple digital hygiene rules will allow you to keep your phone book in perfect order. Your Xiaomi will run faster, and finding the right person will take seconds, not minutes.
💡
Tip: Check the Spam and Blocked section in your contacts periodically, and sometimes important numbers mistaken for spam get there and you need to manually return them to the main list.
