Why Xiaomi System Apps Lost Contacts and How to Get Them Back

You open a phone book on Xiaomi to call a friend, but instead of a contact list, you see a blank screen or an error notification. Or worse, contacts appear in one app (like Google Contacts) but are completely absent from a standard Phone or Messages. Is the situation familiar? This problem occurs on Xiaomi, Redmi and POCO devices regardless of the model — whether it’s the flagship Xiaomi 14 Ultra or the budget Redmi Note 12.

Causes of disappearance of contacts from system applications can be as software (failures) MIUI, Synchronization errors, hardware errors, memory damage, and in this article, we will discuss 5 key reasons why this happens, and give step-by-step recovery instructions. MIUI, which block access to contacts for individual applications – this feature of the firmware is not mentioned anywhere.

1. Sync error with Xiaomi or Google account

The most common cause of missing contacts is a cloud account sync failure. Xiaomi devices by default link contacts to a Mi Account (if you created one) or a Google account (if you use Google services), if sync is disabled or an error occurs, system applications stop seeing data.

How to check:

• 🔄 Open the Settings. → Accounts and synchronization.
• 📱 Choose Mi Account or Google (depending on where the contacts were saved).
• 🔍 Make sure the Contact switch is on and there is no error icon (exclamation point) nearby).
• 🔄 Press Synchronize manually.

If the synchronization is not started, try:

1. Sign out of your account and log in again.
2. Update your Google Contacts or Mi Account app through the Play Store.
3. Check your internet connection – synchronization requires a stable connection.

2. Resetting the permission to access contacts for system applications

One of the things about MIUI is that once you update your firmware or reset your settings, your system applications (Phone, Messages, Contacts) may lose access to your phone book, and it's not a bug, but a security measure, because the firmware resets permissions to prevent data leaks.

How to restore access:

1. Go to Settings → Applications → Application Management.
2. Find the Phone app (or Contacts, Messages).
3. Select Permissions → Contacts.
4. Set the Permission.

Find the phone app in the settings

Open the section “Permissions”

Enable access to contacts

Reboot the device (optional)-->

If permissions are not on the list, the app has been disabled or removed.

• 🔧 Reinstall the system application through Settings → Annexes → Show all applications → Three dots (menu) → Reset to the factory settings of the application.
• 🔄 Reboot the phone.

3. Conflict between multiple sources of contact

On Xiaomi devices, contacts can be stored in multiple locations at the same time:

• 📱 Local phone memory (without synchronization).
• ☁️ Mi Account (Xiaomi Cloud).
• 📧 Google Account (Gmail).
• 📌 SIM-map (obsolete method).

If the contact display settings are the wrong source, the system applications will show a blank list, for example, you save contacts to Google, and the Contacts app only displays data from the contact data. SIM-map.

How to fix it:

1. Open the Contacts app.
2. Click on three dots (menu) → Settings → Contact management.
3. Select Display Contacts from and tick all the necessary sources (it is recommended to enable Google and Mi Account).

💡

If you use multiple Google accounts, make sure that contacts are saved in the main profile. To check, open contacts.google.com on your computer.

4.Damage to the Contact Database after the MIUI Update

Updates to MIUI firmware sometimes damage the local contact database, and this happens because:

• 🔄 Incomplete update (interrupted installation).
• 📉 Conflict of versions between old and new data.
• 🛠️ Errors in memory optimization by the system.

Signs of base damage:

• Contacts are displayed, but without names (numbers only).
• The Contacts app freezes or closes when opened.
• Error of reading contacts.

Decisions:

1. Resetting the cache of the application Contacts: Settings → Applications → Contacts → Memory → Clear the cache
2. Restore from backup (if it is in Mi Cloud or Google Drive).
3. Manual export and import contacts: Open Contacts → Menu → Contact Management → Import/Export. Export contacts to a.vcf file to a memory card. Delete all contacts from your phone. Import the file back.

5. MIUI restrictions for second space or guest mode

The proprietary MIUI function, Second Space (or Guest Mode), can block access to contacts in the main profile. If you activate this option, system applications in the second space will not see contacts from the main account, and vice versa.

How to check:

• 🔍 Go to Settings. → Special facilities → Second space.
• 🔄 If the function is enabled, turn it off or move the contacts between spaces through the Second Space Settings. → Data portability.

MIUI also has a hidden "Private Contacts" setting that can hide some of the records from system applications to disable:

1. Open Contacts → Menu → Settings → Privacy.
2. Turn off the option to hide private contacts.
3. Reboot the phone.

💡

The second space in MIUI creates a completely isolated environment, and contacts, messages, and files don't sync automatically between spaces, but they need to be moved manually.

6 Hardware problems: memory damage or SIM-map

If all software methods did not help, the reason may be hardware:

• 💾 Damage to the memory partition where contacts are stored (more common after falls or overheating).
• 📶 Malfunction SIM-cards (if the contacts are saved on it).
• 🔋 Wear of flash memory (relevant to older Redmi models) 4/5).

Diagnosis:

• Try inserting. SIM-card to another phone – if contacts are displayed, the problem is in the device.
• Connect the phone to your computer and check the integrity of the file system through ADB: adb shell df -h (if there are errors in the /data partition, repair is required).

⚠️ Note: If you suspect a hardware malfunction, do not try to disassemble the phone yourself - this may lead to loss of warranty. Contact the Xiaomi service center with the error code (if it appears in Settings). → The phone. → Status).

What if no method has worked?

If you’ve tried all the ways, but contacts still don’t show up:

1. Make a full backup through Settings → Additional → Backup and Reset.
2. Perform a reset to factory settings (last option).
3. Contact us for support of Xiaomi: 📧 Write to support@mi.com with a description of the problem (specify the model, version) MIUI and steps that have already been tried). 📞 Call the hotline (the number for your region can be found on the official website).

If contacts are critical (such as work numbers) and there is no backup, try to restore them through specialized programs like Dr.Fone or Tenorshare UltData. However, success is not guaranteed, depending on the extent of the data damage.

⚠️ Note: Using third-party data recovery software may violate Xiaomi’s privacy policy.Do not share your account with third parties – this is contrary to the user agreement MIUI.
