How to disable the blacklist on Xiaomi: all ways to unlock contacts

The blacklist on Xiaomi smartphones is a built-in MIUI feature that blocks unwanted calls, SMS and notifications from selected contacts. However, sometimes users are faced with a situation where the desired numbers accidentally fall into this list, and standard methods for removing them do not work. In this article, we will discuss all the current ways to disable the blacklist on Xiaomi, Redmi and POCO devices – from basic settings to advanced methods through ADB.

Complicating the problem is that different versions of MIUI (12, 13, 14 and HyperOS) may have different interfaces and options, and we will take these nuances into account and provide instructions for each version, and we will also look at cases where the blacklist does not appear in the security menu, which is a common problem after updates or resets.

1. Standard method: through the application "Security"

The easiest method is to use the built-in Security app (or Security in global firmware), which is available on all Xiaomi smartphones regardless of the model – be it the Redmi Note 12 or the POCO X5 Pro.

Instructions:

• 📱 Open the Security app** (Icon with shield).
• 🔍 Go to the Blacklist (or Blocklist in English version).
• ✏️ Click on the pencil icon (edit) in the upper right corner.
• 🗑️ Select the numbers that need to be removed and click Delete.

If the Blacklist section is not on the main menu, try the path: Security → Lock → Blacklist. On MIUI 14 and HyperOS, this section may be called Locked Numbers.

💡

If the Security app is missing, check the Other Apps folder or install it via Google Play (it is hidden on some firmware).

2. Deletion via “Phone” and “Messages”

In some versions of MIUI, the blacklist is duplicated in the standard Phone and Messages apps, which is handy if you want to unlock only calls or SMS separately.

Through the Phone app:

1. Open the phone (the phone icon).
2. Press three points (⋮) top-right → Settings.
3. Select the number lock or the blacklist.
4. Remove unnecessary numbers by swiping left or via the Remove button.

Through the Messages app:

• 💬 Open the message»**.
• 🔍 Tap it on three points (⋮) → Settings → Spam and blocking.
• 📋 Go to the Blacklist and manage blocked contacts.

3. Resetting the blacklist through MIUI settings

If standard methods don’t work, try resetting your lock settings through the system menu, which is suitable for Xiaomi on MIUI 12-14 and HyperOS.

Step-by-step:

1. Open Settings → Applications → Application Management.
2. Press three points (⋮) → Special access.
3. Select Blacklist Access (or Blocklist Access).
4. Disable access for all applications except Security and Phone.
5. Return to Settings → System → Resetting of settings → Resetting of application settings.

After reset, check the blacklist, it should be empty. If the numbers are left, then they are tied to the Mi Account account (more on this below).

4 Unblocking through Xiaomi account (Mi Account)

Many users don’t know that a blacklist on Xiaomi can sync with the Mi Account cloud. If you delete a number on your phone but it reappears, that’s the problem.

How to Clean a Cloud Blacklist:

• 🌐 Go to account.xiaomi.com and log in.
• 📱 In the Devices section, select your smartphone.
• 🔒 Find the option Blacklist or Blocked numbers (can be hidden in Additional settings).
• 🗑️ Remove all numbers and save the changes.

Then sync on your phone: Settings → Xiaomi Account → Sync → Blacklist. If you don’t have an option, update the Security app** via Google Play.

5. Advanced method: removal via ADB

If neither of these methods worked, it’s ADB (Android Debug Bridge), a method that requires connecting the phone to a computer and basic command line knowledge, and is suitable for Xiaomi on any version of MIUI, including HyperOS.

Instructions:

1. Turn on Developer Mode on your phone: Settings → About Phone → MIUI version (click 7 times).
2. Activate Debugging by USB in Settings → Additional → For developers.
3. Connect your phone to your PC and install ADB Tools.
4. Open the command line (Windows) or the terminal (Mac/Linux) and type:

adb shell


pm clear com.miui.securitycenter




pm clear com.android.contacts




pm clear com.miui.blocklist

After you've done the commands, reboot your phone. The blacklist will be reset. If you want to delete a specific number, use:

adb shell content delete --uri content://com.miui.blocklist/blocked_number --where "number='1234567890'"

(Replace 1234567890 with the desired number).

💡

ADB-The reset removes ALL blocked numbers, including those added through third-party applications (e.g. Truecaller).

Problems and Solutions: What to Do When Nothing Helps

Sometimes the blacklist on Xiaomi is counterintuitive: numbers aren't deleted, the list is empty, but calls are blocked anyway.

💡

If you still have a problem after all the manipulations, try creating a new user profile in Settings → System → Multiple users. This will reset the lock settings for the new profile.

⚠️ Note: Some Xiaomi firmware for China (CN-ROM) The blacklist is managed through the application "Mi Security"**, which does not have a Russian interface. In this case, use a translator or install global firmware.

7. Alternative methods: third-party applications

If Xiaomi's built-in tools don't work, you can use third-party applications to manage lockdown.

• 📞 Truecaller – blocks spam and allows you to manage a blacklist separately from the system.
• 🛡️ Hiya – specializes in blocking fraudulent calls.
• 🔒 Blacklist Plus – advanced settings for blocking keywords in SMS.

The advantage of third-party apps is that they are independent of MIUI and work even after resetting, but they can conflict with the built-in lock, so disable the system blacklist before using it.

⚠️ Note: Apps like Truecaller require access to contacts and call history, and if privacy is more important than functionality, use them with caution or abandon them in favor of system tools.
