Where to blacklist Xiaomi Redmi: The Complete Guide

Xiaomi and Redmi smartphone owners often encounter intrusive calls that interrupt important conversations or rest. MIUI security provides a powerful built-in tool to filter unwanted contacts, but finding it the first time is difficult because of the localization of the interface. Users look for where the blacklist in Xiaomi Redmi to block the numbers of scammers or just unpleasant interlocutors.

In this article, we will take a look at all the ways to access the lock list, from standard call settings to hidden features of the Security app, how to quickly add a number to the stop list, how to set up automatic lock of hidden numbers, and what subtleties exist in different versions of the MIUI 14 shell and later.

It’s worth noting that menu layouts may vary slightly depending on regional firmware (Global, China, EEA). However, the logic of the system remains the same for all models, whether it’s a budget Redmi Note or a flagship Xiaomi 14.

Search for function through the phone application

The fastest and most obvious way to get into lock settings is to use a standard call app. This is where users most often find an unwanted number after a missed call. The MIUI ringer interface has a specific menu that is not always intuitive at first glance.

To start, open the Phone app and go to the call history tab. Find the number you want to block in the list. Click on the arrow icon or the letter "i" to the right of the number to open the contact card. In the menu that opens, select the Block or Blacklist option.

If you need to manage the entire list, the algorithm of actions will be as follows:

• 📞 Open the Phone app and click on the three dots in the top right corner of the screen.
• ⚙️ In the drop-down menu, select Settings (or Call Settings»).
• 🚫 Find the Blocking or Blacklist section».
• 📝 Here you will see a complete list of blocked contacts and can edit it.

It's important to understand that in some versions of the firmware, this item may be called "Antispam." It's the same menu, just the name is adapted to the marketing terms of the company. The functionality remains the same: complete control over incoming traffic.

Configure through the Security app

The central control node in Xiaomi smartphones is the Security app. This is where all the security tools, including antivirus, memory cleaning and, of course, call filter and SMS are concentrated. This method is the most reliable, since access to it does not depend on the version of the “caller”.

Find an icon on your desktop or in the Tools folder called Security (green shield), launch the app and scroll down to the Tools section, and we're interested in a block called Antispam, and if you click on it, you'll be taken to a full-fledged filtering control center.

⚠️ Note: When you first start Antispam, the system may request permission to access the call log and contacts. Without these rights, the lock function will not work, so be sure to confirm the request.

Inside the Antispam menu, you will see two main switches: for calls and for calls. SMS-Not only can you look at the blacklist, but you can also set the security levels, like locking all the hidden numbers or numbers that aren't in your phone book.

To add a specific number manually:

• 🔢 Click on the button with the person and plus (usually in the upper right corner).
• 📲 Choose the way to add: from contacts, from call history or manually.
• ✍️ Enter the phone number and confirm the action.

This is particularly useful because it allows you to create complex rules, so you can set up your phone to only let calls from your favorite contacts, ignoring everyone else, and it's ideal for Do Not Disturb mode or when you're attacked by spambots.

Managing a blacklist and adding contacts

Once you've found the right partition, you'll have to manage the list properly, and it's not enough to just lock one number if you're attacking different SIM cards or changed numbers, and MIUI allows you to create flexible rules.

In the list management menu, you can see the status of each blocked contact, the system automatically tags the numbers that have been identified as spam by databases, and you can manually add exceptions or expand the block list.

Let’s take a look at the main activities available in this menu:

• 🗑️ Delete: (long press) a number allows you to remove it from the blacklist by unlocking the contact.
• 📥 Import/Export: You can save the block list or transfer it from another device.
• 🔔 Notifications: Set up whether the phone will vibrate or show a notification of a blocked call.

The feature “Keyword Blocking” deserves special attention. SMS-You can add words such as "credit," "winning" or "promotion" and all messages containing these terms will be automatically deleted without disturbing you.

⚠️ Warning: Be careful when blocking short numbers of banks or service providers.If you accidentally add a shipping or bank number to the blacklist, you will not receive a confirmation code to log in to the app.

For mass number additions, it is convenient to sync with the Mi Cloud cloud. If you previously saved locks on another Xiaomi phone, they will automatically be pulled into the list after logging into your Mi Account.

Table of blocking functions in MIUI

To better understand the system’s capabilities, let’s compare the main lock types available to Redmi and Xiaomi owners, and understand the difference between the two will help set up the phone as efficiently as possible.

As you can see from the table, the most flexible tool is the Antispam application, which combines all of these functions, and using only manual locking through the caller is often not effective enough in today's spam environment.

It’s also worth mentioning that new versions of MIUI 15 and HyperOS add smart security that uses cloud databases to detect spam calls in real time, which works in conjunction with the blacklist and automatically updates it.

Hidden settings and codes

For advanced users who want maximum control, there are hidden engineering test menus, but they need to be used with extreme caution, and one wrong step can lead to a network reset.

There is no one Xiaomi phone in the world. USSD-It's a code that would open a blacklist, because it's a function of the shell layer, not the SIM card. However, there are codes to check the forwarding status, which is indirectly related to the lock.

For example, the *#61# code will show where a call is redirected if you don't pick up the phone. Some operators use voicemail redirects as a lock-in, but this is not a blacklist in the MIUI sense.

It will be more useful to use commands in the Phone application to reset call settings if the lock menu is not working correctly:

Settings → Applications → All applications → Phone → Resetting settings

This procedure will clear the cache of the call app and can return missing menu items, including access to the blacklist.Be sure that important numbers are saved to contacts or the cloud before resetting.

⚠️ Warning: Never enter network reset commands (##4636## And so on, without understanding their purpose, this could lead to the loss of access to the mobile Internet (LTE/5G).

It’s also worth remembering that third-party launchers or themes can hide standard interface elements. If you can’t find a menu item, try temporarily switching to a standard theme.

Solving the blockage problems

Despite the system’s cleverness, users sometimes encounter bugs, such as a blacklist that may stop updating or blocked numbers continue to be fed into the call log (albeit without sound), most often the problem lies in the application’s permissions.

Go to Settings → Apps → All apps. Find the Antispam app (may be called MiuiSms or SecurityCenter). Check the Permissions section. Make sure that the phone, contact and SMS rights are enabled.

Another common problem is conflict with third-party number detectors (Yandex, GetContact, Kaspersky) If you have multiple call control applications installed, they may conflict, leaving only the built-in MIUI determinant or disabling it completely in favor of a third-party.

Algorithm for conflict resolution:

• 📱 Disable third-party number detectors in phone settings.
• 🔄 Reset the device.
• 🛡️ Check the built-in blacklist.
• ✅ If the problem is solved, the third-party application is no longer needed.

Also worth checking is the system updates. Xiaomi regularly releases security patches that fix bugs in the Security module. The current firmware version guarantees compatibility with the latest spam number databases.

💡

Use the whitelisted Do Not Disturb mode if you are attacked by too many numbers, turn it on in the notification curtain and set it to allow only "Favorites" calls.
