Xiaomi Redmi Blacklist: Where to Find and How to Use it in 2026

Are you tired of intrusive calls from unknown numbers or want to block a former colleague’s contact, but can’t find where the blacklist is hidden in the Xiaomi Redmi phone? No wonder: in MIUI, this section is hidden deeper than in standard Android, and its location has changed with the release of new versions of firmware. In this article, current ways for MIUI 12, 13 and 14, including hidden features and nuances for specific models (from Redmi Note 9 to Redmi 13 Pro).

We'll not only look at how to open a blacklist, but also how to add numbers, why some contacts aren't blocked, and what to do if a Suddenly partition disappears after an update, and a unique life hack to block it. SMS-Spam without third-party applications, which is not written even in the official documentation of Xiaomi.

1. Standard method: through the application "Phone"

The most obvious way is through the built-in Phone app (the handset icon on the desktop), but MIUI often hides this section under several menu layers.

1. Open the phone app (don’t confuse it with Contacts!).
2. Swipe on the three dots in the upper right corner (or swipe left on some models).
3. Select the Settings item → Number locking.
4. Here you will see two sections: Blacklist (already blocked numbers) and Add to Blacklist.

On Redmi Note 12 and later, the path may be slightly different: instead of Setting up, look for the Spam tab in the bottom menu of the Phone app. If you have MIUI 14, the developers have added a separate Lock and Spam button with a shield icon.

Make sure the number is saved in the contacts (if you want to block a particular person)

Check if the Do Not Disturb mode is on (it can block the lock)

- Remember that the lock only works for calls (SMS block separately)-->

Important: If you see a blank list on this menu but are sure you’ve added numbers before, try updating the Phone app via Google Play. On some firmware, a blacklist bug solves this way.

2. Alternative path: through the "Settings" of the system

If the Phone application does not display the lock section (this happens after resetting settings or on custom firmware), try to find the blacklist through the system settings:

1. Open the Settings → Applications.
2. Slip on the three points in the top corner and select Special Access.
3. Scroll down to the number lock and click on it.
4. The system will redirect you to the Phone app, where the blacklisted section will open.

This method works even if the phone icon is hidden or removed from the desktop. On Redmi 10A and Redmi 9C with MIUI 12.5, the path can look like Settings → System → Advanced Settings → Lock numbers.

3.How to add a number to the blacklist: Step-by-step

You can add a contact to the lock in three ways.

• 📞 From the call log: Find a number in the story, tap it → ⚙️ → Lock down.
• 👤 From Contacts: Open Contact → ⚙️ → Block (or more) → Add to the blacklist).
• ➕ Manual: In the section Blocking numbers, click Add and enter the number manually.

MIUI 14 has introduced the Keyword Block feature, which allows you to block calls from numbers containing certain numbers (for example, all numbers with the prefix +375 to block Belarusian spam) to activate it:

1. Go to the phone. → spamming → Settings.
2. Enable the Keyword Filter option.
3. Add room masks (for example, 495 for Moscow rooms).

💡

If you want to block a number that is not saved in contacts, but often calls, add it to the blacklist manually via Phone. → Journal → ⚙️ → The system will remember it even without saving it in the phone book.

4.Why the number is not blocked: 5 common reasons

Sometimes users are faced with blocked numbers continuing to call, and here are the main reasons and solutions:

Feature for Redmi Note 11 and Redmi 12: If you have a dual-sim, the lock can only work for the main one SIM-To block the number for both SIMs, add it to the blacklist twice - once for each slot.

5. Blacklist for SMS: Separate setting

Many people don't know that call blocking and SMS are set up separately to prevent messages from spammers:

1. Open the Messages app (the envelope icon).
2. Slip on three points → Settings → Spam and blocking.
3. Enable the spam filter option and add numbers manually or from the unwanted list.

MIUI 14 has introduced Automatic Filtering, which is a system that detects spam from Xiaomi's database, to activate it:

• 🔍 Go to Messages. → spamming → Filter settings.
• 📊 Enable Cloud Filter and Local Filter.
• ⚠️ Allow access to messages (a system request will appear).

Note: The cloud filter can send metadata messages to Xiaomi servers for analysis. If you are concerned, use only local lock.

6. Hidden blacklist features in MIUI

In the firmware MIUI there are undocumented features for working with locking, which few people know:

• 🔄 Export/import blacklist: You can save the list of blocked numbers to a file and transfer to another phone. → Lockdown → ⚙️ → Imports/Exports.
• 📊 B B B blocking statistics MIUI 14 Block Log, which shows how many calls were blocked in a week/month.
• 🔇 Quiet lock: Instead of full lock, you can turn on Quiet call mode - the number will ring, but without sound and vibration (useful for important but annoying contacts).

The Redmi K50 and Redmi Note 12 Pro+ have another hidden feature called geolocation lock, which allows you to automatically block numbers from certain countries, so you can turn it on:

1. Go to Phone → Spam → Settings → Geo-filter.
2. Select countries from the list (e.g. USA, India, Nigeria – popular sources of spam).
3. Save the settings and restart the phone.

💡

The geo-locking feature only works on MIUI firmware for the global version (EEA/Global), but it is not available on the Chinese version (China ROM) due to local laws.

7 What to do if the blacklist disappears after the update

After major MIUI updates (e.g. 12-on-13 or 13-on-14), the lock section may disappear.

1. Check if the Settings section is hidden → Additional → Special Features → Simplified Mode. Turn off Simplified Mode if it is active.
2. Reset the settings of the application Phone: Settings → Applications → Phone → Storage → Reset.
3. Install the phone app update via Google Play (even if you have it system-based).
4. If nothing helps, reset your network settings: Settings → Connections → Network reset.

A critical nuance for Redmi 10 and Redmi 9: On these models, after upgrading to MIUI 13, the blacklist can migrate to the Security app (shield icon).

💡

Before resetting settings, export the blacklist through your phone → Lockdown → ⚙️ → Export to avoid losing all blocked numbers.

8 Third-party applications for extended locking

If the built-in MIUI features aren’t enough, try these proven apps (all run on Xiaomi Redmi without root rights):

Warning: When using third-party blockers, disable the built-in lock in MIUI to avoid conflicts, otherwise the records of missed calls may disappear.

On Redmi with MIUI 14, some applications (like Truecaller) may not work properly due to the limitations of the new firmware version, in which case try Blacklist, which integrates better with system services.
