Losing important phone numbers on a smartphone is always a stressful situation, especially if the list of saved includes working partners or loved ones. Xiaomi Mi 6, despite its age, is still actively used by many owners, and the issue of data security remains relevant for them. Fortunately, the Android operating system and the proprietary shell MIUI offer many mechanisms for protecting information that many users do not even know.
Before panicking and searching for complex paid data recovery programs, you need to make a thorough diagnosis of the current situation. Often contacts are not lost, but simply hidden due to a display failure or incorrect synchronization settings. In this article, we will discuss all possible scenarios, from simple settings checks to working with cloud archives.
It's important to understand that the success of the operation depends on whether the backup functions were turned on before the data was lost. If you regularly used Google or Mi Cloud services, the chances of returning information are almost 100%. Even if the phone was reset to factory settings, the services' digital memory can store the history of changes over the past 30 days.
Diagnostics and verification of display settings
The first step before any active action is to check the display filters in the standard Contacts app, often by accident, users hide certain groups or change the source of the display, thinking that the data is lost irretrievably, which is the most common reason for the "disappearance" of numbers after a system update.
Go to the app and click on the three dots or settings menu in the corner of the screen. Find the item that is responsible for the contacts you display. Make sure that you tick the box against "All contacts" or select specific accounts where your phone book is stored. If only selected. SIM-The card and the numbers were in the phone memory, you just won't see them.
Also worth checking is if duplicates are combined automatically. MIUI has a smart merging feature that sometimes works incorrectly, hiding numbers in the archive or flagging them as spam. Go through the Archive or Locked tab to rule this out.
⚠️ Note: If you see contacts but they look like "Unknown" or only contain numbers without names, the problem may be encoding or syncing with an account where the names were not saved.
💡
Before any manipulations, take a screenshot of the current status of the contact list or export what is visible to the file.vcf. This will create a rollback point if your actions lead to the complete disappearance of the data.
In some cases, a simple reboot of the device helps: press the power button and select a reboot, or use a combination of volume and power buttons to force a restart if the sensor does not respond. This updates the cache of system applications, including the phone book.
Recovery through Google Account
The most reliable and common way to return lost numbers to the Xiaomi Mi 6 is to use Google’s built-in restore tool.The service automatically backs up contacts every 24 hours if sync is enabled, which works even if you’ve changed your phone or upgraded your firmware.
To get started, you’ll need a computer or other smartphone with internet access. Go to the official Google Contacts website and log in to the same account used on your Mi 6. On the left side of the screen, find a menu represented by three horizontal lines or a gear icon.
From the menu that opens, select Settings or Cancel Changes, and the system will select the time period to rewind the status of the phone book, and options are available: 10 minutes ago, 1 hour, yesterday, week, or select a specific date (up to 30 days ago).
- 🔄 Select the appropriate date prior to the time of data loss.
- 📂 Confirm the action by clicking the “Cancel” or “Restore” button».
- ⏳ Wait for the end of the synchronization process on the smartphone.

Settings → Accounts and sync → Google → SynchronizationMake sure the switch opposite Contact is active. If it's already on, try turning it off and on again to trigger forced synchronization. In a few minutes, the list of numbers should be updated.
Using the Mi Cloud
Xiaomi device owners have access to their own Mi Cloud storage, which is often ignored in Google’s favor but has its own unique features, including allowing them to retrieve contacts from remote devices if they were linked to the Mi Account.
Go to i.mi.com from any browser. Sign in using your Mi Account. In the web version, select the Contacts icon. At the bottom of the screen or in the settings menu (cogs), find the Contact Recovery feature.
The system will show you a list of available backups with their dates of creation. Select the desired version and click "Restore." All selected contacts will be downloaded to the device, provided that it is connected to the Internet and synchronization in the phone settings is allowed.

Import and export via file.vcf
If you have a backup file with the.vcf (vCard) extension, the recovery process will take only a few seconds, often created automatically when you transfer data from your old phone or manually by the user before flashing it.

☑️ Pre-import checks
In the settings of the Contacts app on the Xiaomi Mi 6, there is a built-in tool for working with files. Go to Settings → Import / Export contacts → Import from the device memory. The system itself scans the memory for the presence of suitable files.
Once the import is complete, it is recommended to check several random numbers for the correct display of names and photos. Sometimes when importing from older versions of Android, format conflicts may arise that require manual editing.
Recovery of data from SIM-map
Although modern smartphones, including Xiaomi Mi 6, recommend storing data in the cloud, many users out of habit keep numbers on the Internet. SIM-If you upgrade your phone or reset your settings, the contacts may remain on the SIM but not appear in the interface.
To check, open the Contacts app and go to import settings. Select the option “Import with” SIM-The system will tell you to choose where to save the numbers: in memory of the phone or in the Google account.

If the phone can't see SIM-The card or import option is inactive, check the physical condition of the tray and SIM card contacts. wipe the contacts with soft cloth and make sure the card is installed correctly according to the scheme in the tray.
Working with local MIUI backups
MIUI has a powerful built-in local copy creation tool that works independently of cloud services. If you have previously backed up your system or only made contacts through the standard Security or Settings app, data can be stored in your phone’s memory.
The path to this data is usually hidden from the average user. To access it, open the Explorer app and go to the MIUI/backup/AllBackup folder. This is where the archives with the date of creation are stored. Contact files are usually.bak or are located inside the system's shared archive.
To recover, go to Settings → About Phone → Reservation & Restore → Restore. Select the date you want and tick only Contacts so you don’t overwrite other data if you don’t need to.
💡
Local MIUI backups are stored in your phone’s memory. If you’ve done a full Wipe All Data reset without saving a copy to your computer or the cloud, the local files will be deleted along with the rest of the data.
In some versions of the firmware, access to the backup folder may be limited, in which case you can use a file manager with access rights or connect the phone to a PC in file transfer mode (MTP) to search for archives.
