How to find blocked contacts on Xiaomi: all the ways for MIUI 14 and 15

You blocked a number on Xiaomi, but you forgot who it was? Or you want to check if an important contact was blacklisted by mistake? In MIUI, the list of blocked numbers is hidden deeper than in the stock Android, and its location depends on the firmware version. In this article, 4 proven ways to find blocked contacts on any Xiaomi smartphone (including Redmi, POCO and Black Shark), even if they do not appear in the standard menu.

We'll look at not only the obvious ways to get your phone setup, but also the hidden ways, from exporting data to using an engineering menu, and why some numbers can go blacklisted after a MIUI update and how to fix it. If you're a Xiaomi 13/14, Redmi Note 12 or older model on MIUI 12-15, here's a solution.

1. Standard method: the menu "Number Lock" in MIUI

The easiest method is to use the built-in lock menu, but it has changed in different versions of MIUI, so the instructions depend on your firmware.

For MIUI 14/15 (relevant to Xiaomi 13/14, Redmi Note 12/13, POCO F5/X5):

1. Open the phone application (pipe icon).
2. Slip on the three dots in the upper right corner → select Settings.
3. Go to the section "Number Lock" (or "Spam and Lock" on some models).
4. Enter. PIN-password/code if requested.
5. This will show you a list of all blocked contacts and numbers.

For MIUI 12/13 (e.g. Xiaomi 11/12, Redmi Note 10/11):

• 📱 Open the Settings. → Annexes → Application management.
• 🔍 In the search, enter "blocking» → select Number Locking.
• 🔐 You may need to enter a password from your Mi Account.

⚠️ Warning: If there are no blocked numbers on the list but you are sure you have blocked contacts, check sync with Mi Cloud. MIUI Local blacklist is zeroed, but cloud list is not.

2. View through the call log (hidden filter)

Few people know, but MIUI has a hidden filter in the call log that shows locked numbers -- even those that don't appear in the main lock list -- that works on all firmware versions, including MIUI 15.

How to find it:

1. Open the Phone application → go to the Journal tab.
2. Slip on the filter icon (three lines with circles) in the upper right corner.
3. In the drop-down menu, select Blocked (or Spam and Blocked).
4. The system will show all incoming calls from numbers that have been locked automatically (via spam protection) or manually.

This is useful if you want to see the history of blockings — for example, when exactly the blocked number called and how many times — but it does not show contacts blocked through Messages or third-party apps.

💡

If the Locked filter is not on the menu, update the Phone app via Google Play or Mi App Store.Sometimes the feature is hidden due to an outdated version.

3.Export and analysis of lock data (for power users)

If standard methods don't work, you can export the lock data to a file and view it on a PC, which is suitable for MIUI 14/15 and requires connecting the smartphone to a computer.

Instructions:

1. Connect Xiaomi to your PC via USB (in File Transfer mode).
2. Open the Internal Storage → MIUI → Backup → AllBackup folder.
3. Find a file with the.bak extension and a name containing the blocklist (e.g, com.android.contacts_blocklist_20260515.bak).
4. Copy the file on your PC and rename the extension to.zip.
5. Unclose the file – inside will be blocklist.db (SQLite database).
6. Open it with the program. DB Browser for SQLite (free) and go to the Data Overview tab → table blocked_numbers.

In this table, you'll see:

• 📞 Phone numbers in format +7XXXXXXXXXX.
• 📅 Date of addition to the blacklist.
• 🔄 Source of locking (manual/automatic).

⚠️ Warning: Do not edit the blocklist.db file manually, this can cause the lock system to fail. If you want to delete the number, do it through the phone menu.

4. Verification via Mi Cloud (cloud synchronization)

If your Xiaomi has Mi Cloud sync enabled, locked numbers can be stored in the cloud – even if they have disappeared from the local list.

How to check:

1. Open the Settings. → Xiaomi Account (or Mi Account).
2. Make sure that the synchronization of Contacts and Number Locking is enabled.
3. Go to i.mi.com (the web version of Mi Cloud) and log in.
4. In the Services section, select Lock Numbers (or Blacklist in English).

This will show all the numbers locked on the device and synced to the cloud.

• 🔄 Restore your phone (if it is missing locally).
• ❌ Remove from the cloud (if you no longer need to lock).
• 📥 Export to.csv file for analysis.

If the sync is disabled, turn it on and wait for the data update (it can take up to 10 minutes).

5.Use of the engineering menu (for advanced users)

MIUI has a hidden engineering menu that allows you to access low-level settings, including lock data, which is suitable for advanced users and requires caution.

Instructions:

1. Open the phone app and enter the code: ##4636##
2. In the menu that opens, select Phone Information (or Phone Information).
3. Scroll down to the Blocked Numbers section (could be called Call Blocking).
4. All locked numbers, including system numbers (for example, operator locks) will be displayed here.

Advantages of this method:

• 🔍 Shows all locks, including those not visible in the standard menu.
• 🛠️ Allows you to reset the operator’s locks (if they interfere with the work).

⚠️ Warning: Do not change other options in the engineering menu unless you understand their purpose, this can lead to network failures or complete loss of communication.

💡

The engineering menu shows not only user locks, but also system locks (for example, blocking spam numbers from the operator). If you see unfamiliar numbers here, this is not a mistake, but the work of protecting against fraudsters.

6. Third-party applications for blocking management

If the built-in MIUI tools don't work, you can use third-party apps, which not only show locked numbers, but also offer advanced features like blocking keywords in SMS or blocking schedules.

Top.-3 apps:

How to transfer locks from MIUI to a third-party application:

1. Export the list of blocked numbers through the standard menu (see Section 1).
2. In the selected application, find the import function (usually in the blacklist settings).
3. Download the file with numbers (.csv or.txt format).

Warning: Some applications (such as Truecaller) may conflict with the built-in MIUI lock. If standard locks stop working after installation, disable duplicate functions in the application settings.

Frequent problems and solutions

Sometimes blocked contacts disappear or don't appear on the list, and let's look at the typical causes and ways to fix them.

Problem 1: After the MIUI update, the blacklist is empty.

• 🔄 Solution: Check sync with Mi Cloud (see section 4). If the locks were only local, they could reset.
• 📱 Prevent: Before updating, export the block list to the file (Section 3).

Problem 2: The numbers are blocked, but the calls still pass.

• 📞 Solution: Disable the Allow Emergency Calls feature in the lock settings. Some operators (such as MTS or Beeline) bypass the lock for "important" numbers.
• 🛠️ Additional: Check if an application from an operator (such as My MTS) has been installed that can reset settings.

Problem 3: Not all numbers are listed in the blacklist.

• 🔍 Solution: Use a hidden filter in the call log or an engineering menu – they show the full list.
• 📊 Reason: B MIUI The standard menu can only show manual and automatic locks (from spam filter.

💡

If you use two of them SIM-Cards, locks can only be used for the main SIM. To block the number for both cards, add it to the blacklist separately for each card.
