When a phone book disappears after a system upgrade, accidental reset or screen breakage, it causes panic in any smartphone owner. For users of the Xiaomi ecosystem, this is especially true, since the synchronization structure here has its own features, different from pure Android. Losing important numbers of colleagues, friends and delivery services can paralyze business activity and personal communication.
Fortunately, the operating system architecture MIUI And HyperOS has multiple layers of backup that many people don't even know about, and it can be stored in the manufacturer's cloud storage, on Google's servers, on the company's servers. SIM-Understanding where to find lost information is the key to successful recovery without wasting time.
In this detailed guide, weโll take a look at all possible scenarios, from simple display settings to using specialized software to scan deep memory, how to prevent future losses and what steps to take in the first minutes after a problem is detected. Donโt rush to write numbers back until youโve tried the methods below.
Checking the settings of the display of contacts
Before you move on to the complex recovery procedures from backups, itโs worth making sure the numbers are really lost, not just hidden by the filtering settings. Often, after updating the firmware or changing the account, the phone by default switches to display only those records that are stored on the phone. SIM-maps, ignoring cloud listings.
To check, open the standard Contacts app and find the menu button, which is usually represented by three dots or bars. From the list that opens, select Display Settings or Contact Filter, and make sure that the box is next to All Contacts or All Phones.
If you had multiple accounts, like your personal Google account and your corporate Mi Account, the system could automatically hide one of the groups, and you can choose in detail from the filter menu which sources should be visible in the general phone book, which is a common reason for "losing" numbers after you log in to a new account.
โ ๏ธ Note: If you see contacts but they look like blank entries without names, perhaps the problem is encoding or synchronizing rather than physically deleting data.
It's also worth checking if you've activated a "Favorites Only" mode or any third-party launcher that could have changed how the phone book works. Returning to a standard look often solves the visibility problem. Make sure that the Contacts app settings don't limit only numbers with a specific country or region code.
Recovery via Mi Cloud (Xiaomi Cloud)
Owners of Xiaomi, Redmi and POCO smartphones have access to a powerful backup tool, the Mi Cloud. This is a native service that often turns on by default when you first set up a device if you log in to your Mi Account. This is where you most often save current copies of your phone book.
To recover data through the cloud, go to the smartphone settings menu and select the "Mi Account" section. Next, you need to find the "Cloud" or "Xiaomi Cloud" option. From the synchronized data list, select Contacts and click on "Restore" or "Sync Now" button.
If you don't have the phone, you can do it through your computer browser. Go to i.mi.com, log in with your ID, and go to Contacts. Contacts is often available at the bottom of the screen or in the site's settings menu, where you can roll back the list 30 days.
Storage limits in Mi Cloud
If the process is stalling, try switching from Wi-Fi to mobile or vice versa. Once the procedure is complete, restart the device so that the changes take effect and show up in the interface.

Synchronization via Mi Cloud only works if the feature was enabled before data loss.
Synchronization with Google account
The Android platform is deeply integrated with Google services, and the phone book is often stored there automatically, even if you use the MIUI shell. This is one of the most reliable ways, since the data is tied to the mailbox, not to the specific hardware of the phone.
To check and restore, go to your phone's settings, Accounts and Sync. Find your Gmail address on the list, click on it and make sure the switch opposite Contacts is active. If it's turned off, turn it on and click Sync.
A more advanced method is to use the Google Contacts web interface. Go to contacts.google.com from a computer or other device. From the menu on the left, select Restore (or find the gear icon), and the system will suggest rolling back the database status by 10 minutes, 1 hour, yesterday or to a custom date (up to 30 days ago).
- ๐ Select the exact date and time prior to the number removal.
- โ Confirm the action, the system will create (snapshot) the current state in case of an error.
- โณ Wait for the process to end, then force the synchronization on the phone to be updated.
This method is especially effective if you have changed your phone or reset to factory settings. Google stores a history of changes, which allows you to return even those contacts that were deleted from the deviceโs memory, but have already synced with the server.

Set the autosynchronization interval in your Google account settings on Daily to minimize data loss.
Import with SIM-maps and local files
Do not ignore the traditional methods of storage, such as SIM-Map and local backup files. Many users still store the main numbers on a SIM, especially if they are old contacts transferred from push-button phones.
To import, open the Contacts app, go to settings and select Import/Export Contacts. Select the source Import from SIM-The system will prompt you to select an account to which the numbers will be saved (it is recommended to choose Google or Phone, but not the phone itself). SIM-map to avoid duplication).
If you have previously done local backups through the built-in Security or Mi Backup app, the database file may be in your phoneโs memory or on an SD card. The path to the file usually looks like MIUI/backup/AllBackup/contacts.
| Source of data | File format | Where to find | Reliability |
|---|---|---|---|
| Google Contacts | Online base | contacts.google.com | Tall. |
| Mi Cloud | Online base | i.mi.com | Tall. |
| SIM-map | Internal memory. | Average (Ogric volume) | |
| Local backup | .bak /.vcf | MIUI/backup folder | Depends on the user. |
When imported from a VCF file that could have been saved in messengers or a file manager, the system automatically recognizes the format and suggests adding entries to the phone book, a universal format that almost all devices understand.
Using third-party applications for recovery
When the built-in tools are powerless, specialized applications from Google Play come to the rescue, which are able to scan internal memory for residual files or cache in which fragments of a remote database may have been saved.
One popular solution is Dumpster, or Windows-based recycle bins, where if the application is installed in advance, remote contacts can be there, but if the application is installed after the fact, it is limited to finding residual files.
More powerful tools like Dr.Fone or DiskDigger (which require root rights for deep scanning) can try to find deleted records in memory sectors that have not yet been overwritten by new data, and the effectiveness of such programs depends on the time elapsed since the deletion.
โ๏ธ Criteria for selecting a recovery program
โ ๏ธ Be careful with programs that require root access. Incorrect use of such rights can lead to a complete lockdown of the bootloader or loss of warranty.
When using third-party software, always check the permissions the app requests. Don't give access to unverified software contacts if you're unsure of the developer; use well-known brands with a good reputation in the Android community.
Preventing Data Loss in the Future
To prevent the loss of contacts from happening again, you need to set up an automatic backup system, which is done once in modern Xiaomi smartphones and works in the background without requiring user intervention.
It is recommended to set up dual sync: simultaneously with Google and Mi Cloud. This will create (redundancy), ensuring that when one service fails, the data will remain in another. It is also useful to export contacts once a month to a VCF file and send it to your messenger or save it to the cloud.
- ๐ Set up a regular reminder to check backups.
- โ๏ธ Use cloud storage instead of storage on SIM-map.
- ๐ Protect accounts with two-factor authentication to prevent hacking.
Regular system updates are also important, as newer versions of MIUI and HyperOS often contain sync bug fixes. Don't ignore notifications of available updates, especially when it comes to system security and stability.
Why are contacts duplicated?
Compliance with these simple rules will allow you to keep control of your phone book in any environment. Backup is not just a recommendation, it is a necessity in the digital age.
