Blocked numbers on Xiaomi often become a “black hole”: users forget who they added to the blacklist, or cannot find this section in the maze of settings MIUI. Meanwhile, in the firmware Xiaomi there are several ways to view the list of blocked contacts - from standard menus to hidden functions that few people know about.

The problem is complicated by the fact that the interface MIUI is regularly updated, and the location of the section with blocking may differ depending on the firmware version and smartphone model (for example, on Redmi Note 12 the path will be different than on POCO F5). In this article, we will analyze all the current methods - from basic to advanced, including restoring deleted entries from a blacklist.

Important: if you use third-party applications to block calls (for example, Truecaller or GetContact), the list of blocked numbers may be stored not in the system settings, but in the application itself. More on this in a separate section.

Method 1: Standard “Black List” section in MIUI

The most obvious and fastest method is to use the built-in function MIUI to manage locks. This method works on all smartphones (including global and Chinese versions). Xiaomi, Redmi And POCO with firmware MIUI 12–14 (including global and Chinese versions).

Instructions:

  • 📱 Open the application Phone (icon handsets on the main screen).
  • 🔍 Click on the three dots in the upper right corner (menu) and select Settings.
  • 🚫 Go to section Blocking numbers or Black list (name may differ).
  • 📋 Here you will see a complete list of blocked contacts with the ability to unblock.

If the section Blocking numbers is missing in the menu, which means your version MIUI uses an alternative path. Try:

  1. Go to Settings → Applications → Manage applications → Phone → Permissions → Blocking numbers.
  2. Or via Settings → System and device → Advanced → Blocking and protection → Blacklist.

Check for MIUI updates in Settings → About phone

Make sure the application is running Phone not disabled in Settings → Applications

Restart your smartphone if the menu is not displayed-->

Limitation: this section displays only numbers blocked through the standard application Phone. If you used other methods (for example, through Google Contacts or third-party applications), they will not be here.

Method 2: View via Google Contacts (synchronization)

If your smartphone Xiaomi is synchronized with your account Google, blocked numbers may be duplicated in the cloud. This is useful if you have reset your phone or lost access to the black list in MIUI.

How to check:

  • 🌐 Open the browser on your PC or phone and go to the website Google Contacts.
  • 🔍 Select in the left menu More → Settings → Manage blocking.
  • 📱 All numbers blocked via Google (including those added from other devices) will be displayed here.

Important: numbers blocked via MIUI are not always synchronized with Google. To make them appear in the cloud, when blocking, select the “Block and report spam” option (this sends data to Google).

💡

If you often change smartphones, set up automatic synchronization of contacts and blocks in Google. To do this, go to Settings → Accounts → Google → Synchronization and enable the “Contacts” option.

The advantage of this method is access to the black list from any device, even if Xiaomi lost or broken. However, there is a minus: if the number was blocked only in MIUI (without sending to Google), it will not appear here.

Method 3: Using the Security application

The firmware MIUI has a built-in application Security (shield icon), which controls not only the antivirus, but also call/SMS blocking. This method works on most models Xiaomiincluding Redmi 10, POCO X5 and newer devices.

Step-by-step guide:

  1. Open the application Security (if it is not on the main screen, find it by searching for system).
  2. Go to the tab Blocking or Spam protection (the name depends on the version MIUI).
  3. Select Black list or Blocked numbers.
  4. Here you can not only view the list, but also add new numbers, set up SMS filtering.

In some versions MIUI (for example, MIUI 14 for the global market) the blocking section is hidden deeper:

Security → Settings (gear in the corner) → Blocking and protection → Blacklist

MIUI 12

MIUI 13

MIUI 14

I don’t know/Other-->

Warning: if you have reset your settings phone to factory settings, the black list from the application Security will be deleted. To avoid data loss, export the list of blocked numbers manually (more on this in the next section).

Method 4: Export and import of the black list (backup)

Few people know, but MIUI allows you to export the list of blocked numbers to a file, which can then be imported to another smartphone or after resetting the settings. This is especially useful if you often reflash the device or use custom firmware.

How to save the blacklist:

  • 📄 Open Security → Blocking → Blacklist.
  • 🔽 Click on the three dots in the upper right corner and select Export.
  • 💾 Save the file (usually in the format .txt or .csv) to a safe place (for example, in Google Drive).

To import the list back:

  1. In the same section Blacklist click on the three dots and select Import.
  2. Specify the path to the saved file.
  3. Confirm adding numbers.
What to do if there is no export option?

On some versions of MIUI (especially Chinese), the blacklist export/import function is disabled. In this case, you can manually copy the numbers from the blocking section to a text file or use applications like Blacklist Export Import (available in the Play Market).

This method ensures that you do not lose the list of blocked contacts when you change your phone or reset your settings. However, remember: the exported file is not encrypted, so store it in a secure place.

Method 5: View through the call log (hidden blocks)

Sometimes blocked numbers do not appear in the blacklist, but continue to be blocked. This happens if the blocking was configured through the telecom operator (for example, the Antispam service from MTS or Beeline) or through third-party applications. In this case, you can try to find them in the call log.

How to check:

  • 📞 Open the application Phone → Log.
  • 🔍 Click on the three dots and select Settings → Show blocked (if the option is available).
  • 👁️ Turn on the display of hidden calls - sometimes blocked numbers are displayed in gray.

If there are no traces of blocked calls in the log, but you are sure that there were some, check:

  • 📊 Operator settings: go to your mobile operator’s personal account (via the website or application) and find the “Antispam” or “Number blocking” section.
  • 🛡️ Third-party applications: open Settings → Applications and check which apps have permission to Read call logs and Call blocking.
💡

If a number is blocked at the operator level, it will not be visible in the MIUI settings. To unblock such a contact, you need to disable the service through the USSD command or your personal account.

Method 6: Advanced methods (ADB and system files)

For experienced users who are not afraid to work with system files, there is a way to view blocked numbers through ADB (Android Debug Bridge). This method is suitable if the standard settings are unavailable or damaged. Enabled USB debugging on the smartphone ( MIUI inaccessible or damaged.

What you will need:

  • 🖥️ Computer with installed drivers ADB And Fastboot.
  • 📱 Enabled USB debugging on the smartphone (Settings → About phone → MIUI version - press 7 times, then return to Settings → Advanced → For developers → USB debugging).
  • 🔌 USB cable for connection.

Instructions:

  1. Connect your smartphone to the PC and open the command line (cmd in Windows or Terminal in macOS/Linux).
  2. Enter the command to check the connection: 
    adb devices

    (the serial number of the device should be displayed).

  3. Run the command to get a list of blocked numbers: 
    adb shell content query --uri content://call_log/blacklist
  4. If the command does not work, try an alternative path: 
    adb shell su -c "sqlite3 /data/data/com.android.providers.contacts/databases/contacts2.db 'SELECT * FROM blacklist;'"

    (required root access).

Warning: working with ADB system files can lead to malfunctions of the phone. Do not change the data in the database if you are not sure of your actions. For safety, make a backup copy via adb backup.

💡

If you have root access, you can use a file manager (for example, Root Explorer) and manually open the file /data/data/com.android.providers.contacts/databases/contacts2.db in any SQLite editor.

This method is the most complicated, but it works even if the interface MIUI damaged or modified by custom firmware. However, without technical skills, it is better to use standard methods.

Frequent problems and solutions

When working with a blacklist on Xiaomi users encounter typical errors. Let's look at the most common ones and how to eliminate them.

Problem Possible cause Solution
The black list is empty, but calls are blocked Blocking at the operator level or third-party application Check your operator's antispam settings and application permissions in Settings → Applications
There is no “Blocking numbers” section in the settings Outdated version of MIUI or regional restrictions Update the firmware or use the application Security
After resetting the settings, the blacklist disappeared Local MIUI data is not saved Restore from a backup or export the list in advance
You cannot add a number to blacklist Operator restrictions or database error Reboot your phone or reset the application settings Phone

⚠️ Attention: if you use two SIM cards, the blacklist can only apply to one of them. To block a number on both SIMs, add it to the list twice - separately for each slot.

Another common problem is duplication of blocked numbers. This happens if the number is added to both MIUIand Google Contacts. To avoid confusion, choose one blocking method and stick to it.

Is it possible to restore a deleted blacklist on Xiaomi?

If you did not make a backup copy, you can restore the list only if it was synchronized with Google Contacts. Check the section Managing blocks on the website Google Contacts. If synchronization has not been configured, the data is lost forever.

Why do blocked numbers keep calling?

This happens when three reasons:

  1. The number is blocked only in MIUI, but not at the operator level (some spammers bypass the system blocking).
  2. You are using a third-party blocking application that conflicts with MIUI.
  3. The phone firmware is modified (custom or pirated), and the blocking function does not work correctly.

Solution: check your operator's antispam settings and disable third-party blockers.

How to block a number so that it cannot leave voice messages?

There is no separate setting for blocking voicemail. However, you can: MIUI There is no separate setting for blocking voicemail. However, you can:

  • Disable voicemail from the operator (via USSD command or personal account).
  • Use third-party applications, for example Truecallerthat block all types of communication with the number.
Does the MIUI blacklist work for SMS?

Yes, but with reservations. In standard settings MIUI blocking a number automatically prohibits both calls and SMS. However, some spam messages can get through if sent through Internet instant messengers (for example, Viber or WhatsApp). To completely block, set up filtering in the messenger itself.

Is it possible to block a number without saving it in contacts?

Yes, in MIUI you can add any number to the blacklist, even if it is not saved in the phone book. To do this:

  1. Open the call log.
  2. Find the desired number and click on it.
  3. Select Block or Add to black list.

The number will be blocked without saving it in contacts.
