Why Xiaomi lost contacts: a full analysis of the causes and solutions

You opened a phone book on your Xiaomi and you don't have any contacts, whether it's an empty screen or a download error, and this is familiar to many smartphone users of this brand, especially after a MIUI update or account change, and 80 percent of the time, the problem is solved without going to the service center, but it's important to diagnose the cause correctly.

In this article, we’ll look at all possible contact disappearance scenarios, from trivial synchronization errors to hardware failures, learn how to recover data with built-in MIUI tools, cloud services and third-party utilities, and get a checklist of actions to help avoid future contact loss.

Special attention will be paid to hidden MIUI 14/15 settings, which can block the display of contacts without notifying the user, and these features are often activated after updates or when connecting to corporate networks.

1.Sync with Xiaomi Account: Why Contacts Are Not Shown

The most common reason is a sync failure with the Xiaomi Account cloud. Even if you haven't changed your device, the system can untie contacts from your local database. Check this in the Settings menu → Accounts and Sync → Mi Account → Contacts.

If the switch is turned off or the “Synchronization Stopped” error hangs, perform forced synchronization:

• 🔄 Go to Contacts → Settings (⚙) → Contact Management → Synchronization
• 📱 Select Xiaomi Account and click on Sync Now
• 🔍 If the process freezes, delete your account and add it again (the data will be saved in the cloud)

Note the hidden setting in newer versions of MIUI: the system can automatically turn off sync when the battery is low (less than 15%), which is done to save power, but often results in data loss.

1. Go to Settings → Battery and Performance → Battery Settings
2. Select “Apps Energy Optimization”
3. Find Contacts and Set “No Limits”

💡

Back up your contacts in.vcf format through the Contacts menu → Settings → Export and send the file to the mail. This will save data even if your phone breaks down.

2. Reset settings or update MIUI: how to return contacts

After resetting to factory settings or a MIUI update (e.g., 13 to 14) the contacts may disappear due to:

• 🗃️ Incorrect recovery from backup (file corrupted or outdated)
• 🔄 Conflict of Contact Database Versions
• 🚫 Google account blocking (if Gmail sync was previously used)

The first thing to do is check the backup folder:

1. Open Settings → About Phone → Backup and Reset
2. Select Local Backups and find a file with a date before your contacts go missing.
3. Restore only the Contacts section (do not touch other data)

If you don’t have backups, try to restore contacts through Google Contacts:

1. Go to contacts.google.com from your computer
2. Sign in with the same account as on your phone.
3. From the “More” menu, select “Cancel Changes” and return to the date before you go missing.

💡

Once the settings are reset, MIUI creates a new local contact database, so if you don't restore the data from the cloud in the first 72 hours, the old information can be overwritten.

3. Viruses and Malware: How They Affect Contacts

Malware often disguises itself as system utilities and accesses the phone book.

• 📵 Contacts disappear gradually (first new, then old)
• 🔋 Fast battery discharge even in standby mode
• 📱 Appearance of unknown apps in the menu

Check your phone with the Mi Security Scan:

1. Open Security → Scanning
2. Select “Deep Check” (it will take 5-10 minutes)
3. Remove all threats found and restart the device

If viruses are detected but contacts are not returned:

1. Install Malwarebytes from Google Play
2. Scan the device in Safe Mode (press the power button → “Safe Mode”)
3. After cleaning, check the /sdcard/Miui/backup/AllBackup folder – sometimes viruses move data there.

💡

Some viruses block the contact display but do not delete it. Try exporting the phone book to.vcf even if it is empty - the file may contain hidden data.

4. Hidden MIUI settings: why contacts aren't shown

MIUI 14/15 has features that can hide contacts without notice.

To get back the hidden contacts:

1. Turn off "At Work" mode in settings
2. Check Contacts → Groups – they may be displayed in a separate group
3. Go to Settings → Accounts → Google and turn on display of all contacts

Disable "At Work" | Check contact groups | Turn off Private Mode |Remove geo-restrictions | Double application check-->

5. Hardware problems: when the phone itself is to blame

If contacts disappear periodically (they appear, then disappear), the problem may be:

• 🔋 Faulty battery (caches are dropped when voltage is lower than 3.4V)
• 💾 Damaged memory chip (especially on models with UFS 2.1)
• 📶 Bad antenna contact (affects synchronization)

Diagnose:

1. Install AccuBattery and check the status of the battery
2. Run the memory test using ##6484## (Redmi Note 10/11) only
3. Try inserting another SIM- card – sometimes the operator is a problem.

💡

On the Xiaomi 12/13 series, a common problem is the collapse of the contacts of the eMMC chip. If the phone stops “seeing” contacts after a fall, do not turn it on – this can lead to complete data loss.

If you suspect a hardware malfunction:

⚠️ Warning: Don't try to disassemble the phone yourself - new Xiaomi models use adhesive with shape memory. Incorrect opening can damage the display plumes.

6. Contacts are missing after flashing or unlocking the bootloader

When you unofficially firmware or unlock the bootloader, the /data section where the contacts are stored is often reset.

• 🔓 Unlocked the bootloader via Mi Unlock Tool
• 📱 Installed custom recovery (TWRP, OrangeFox)
• 🔄 Striped an informal MIUI (e.g., xiaomi.eu)

Local contacts are likely lost.

How to restore:

1. Check the /sdcard/TWRP/BACKUPS folder – sometimes automatic backups are saved there.
2. Use Dr.Fone or EaseUS MobiSaver to scan your internal memory
3. If the phone is not turning on, connect it in Fastboot mode and use the command: fastboot pull /data/data/com.android.providers.contacts/databases/contacts2.db (root rights required)

7: Problems with the SIM- card: why contacts do not load

Many users store contacts on the SIM- card, but modern Xiaomi does not work well with this format.

• 📱 Phone does not see contacts on SIM (especially on Redmi 9/10)
• 🔄 When transferring to the phone, characters are duplicated or lost
• 🚫 Cannot edit contacts on SIM

Decisions:

1. Transfer your SIM contacts to your phone: Contacts → Settings → Import/Export → Import with SIM
2. If contacts are not imported, use an old device (like Nokia) as an intermediary.
3. Xiaomi 13/14 series requires SIM with USIM support (ask the operator)

Important: Do not store contacts on SIM – this format supports only name and number (without photos, email or other fields).
