Where is the blacklist in the Xiaomi Redmi phone: the full guide

The modern smartphone, especially the popular Xiaomi Redmi, has become the center of digital life, but with convenience come unwanted calls. Advertising, spam, scammers or just obsessive acquaintances can disturb the peace at any time of the day. Device owners often look for where the blacklist on the phone is to finally find peace and quiet.

The MIUI operating system that runs Redmi smartphones offers built-in and powerful tools to filter calls. You don’t have to download third-party apps that can overload the system or collect personal data. All the necessary functions are already integrated into the standard interface, but finding them the first time is difficult due to the localization and firmware versions.

In this article, we will take a look at all the ways to access the block list, learn how to add a number manually, how to set up automatic spam protection and what hidden features Xiaomi antivirus offers. Understanding these settings will help you fully control incoming traffic.

The main path through the Security application

The most reliable and versatile way to find a blacklist on Xiaomi Redmi is to use the system application Security, which is where all the key device security settings, including call and message control, are concentrated, and works on most current versions of MIUI, regardless of regional binding.

To start, open the app menu and find an icon called Security (green shield). Inside the interface, you'll need to scroll down to the Tools block. Here you'll find the Lock item. If you don't see it right away, it may be hidden in an additional menu that opens with a swipe or a "More" button.

Once you enter the lock menu, you will see the ban control panel, which displays the statistics of blocked calls and SMS. To proceed to edit the list of numbers, you need to click on the gear icon or the Black List button located at the top or bottom of the screen, depending on the version of the shell.

⚠️ Note: The security interface may differ on the global and Chinese versions of firmware. If you do not find the “Block” option, try searching inside the app itself or update it via GetApps.

And it's important to note that this is where the rules are deeply customized, and you can not just add numbers, but you can also customize the behavior of the phone when a call comes from a listed subscriber, and you can choose whether the phone will drop a call, send a busy call, or just silently ignore a call, which is a critical feature for spam protection.

💡

If you have updated MIUI and the interface has changed, use the search bar in the Settings menu of the phone, entering the “Block” request so that the system itself opens the desired section.

Blocking through call log and contacts

There is a faster way to add a specific number to a blacklist without going through complex settings menus.This method is ideal when you need to urgently lock a number that just called. The action algorithm is simple and intuitive for any Redmi user.

Open the standard Phone app and go to the Recent or Journal tab. Find an unwanted number in the list. Click on it and hold your finger for a second, or tap the arrow or "i" icon to the right of the number to open the detailed menu.

In the window that opens, select Add to the Blacklist. In some versions of MIUI, this feature may be called "Block the Number." Once confirmed, the number will instantly be in the database of prohibited contacts. Now you can be sure that this subscriber will not be able to reach you.

• 📞 Go to the call log and find the number you need.
• 🛑 Click on the number and select Add to the blacklist».
• ⚙️ Confirm the action in the pop-up window.
• ✅ Check the add-on through the "Security" app».

You can do the same thing through the Contacts app. Open a person's card, scroll down and find the lock point. This is especially useful when you need to block a contact from your address book, even if they haven't called in a long time. The system automatically synchronizes this status across all the phone services.

Configure the rules of blocking and exclusions

The blacklist functionality of Xiaomi Redmi goes beyond just a list of numbers; it’s a complex filtering system that allows you to create flexible rules, so you can set your phone to block all hidden numbers, or let calls from favorite contacts pass even in “Do Not Disturb” mode.

To access the finer settings, go back to the Lock through Security menu and click on the gear icon. Here you will see the Lock Rules section. This is where you can manage incoming traffic at an advanced level. You can activate locking of all unknown numbers, which will save you from advertising, but you need to be careful not to miss an important call from a courier or a doctor.

The exception feature, which allows you to create a whitelist, a list of numbers that will never be blocked, even if they meet general filtering criteria, is a critical setting for those who are waiting for important calls from unknown numbers, such as delivery services or customers.

You can also set up your response to SMS from blocked contacts in this section, and you can choose whether they will be saved to a separate folder or deleted forever, which helps keep the main inbox clean and not distracted by advertising mailings.

💡

Properly configuring exceptions (whitelisting) is more important than the blacklist itself, as it ensures that you don't miss really important calls.

Use of the spam number database

One of the most useful features in Xiaomi’s ecosystem is its built-in spam database.The phone automatically checks incoming calls against the cloud ledger of known scammers and ad agencies.This eliminates the need for users to manually enter each new spam number.

To activate this feature, you need to be in the lock settings menu. Find the item associated with "Database Update" or "Spam Identification." Make sure the switch is activated. Periodically, the system will request an update of the lists, and it is better to agree to this so that the protection remains up to date.

When you receive a call from a number that is listed in the database, a warning will appear on the screen, such as "Advertising" or "Telemarketing", often with a red mark. You can immediately see how many people complained about this number, which gives you an informed decision: respond or reset.

⚠️ Note: The database only works if you have an active Internet connection. If you are in an area without a network, the identification of spam numbers may not work and the call will pass as usual.

And users can also participate in the replenishment process themselves, and if you get a call from an unfamiliar number and you realize it's spam, you can tag it with the appropriate tag when you complete the call, which will help other owners of Redmi and Xiaomi avoid being scammed.

Hidden Codes and Engineering Menu

For advanced users who want to access lock settings, there are special locks. USSD-However, you should be extremely careful, because changing certain parameters can affect the work. SIM-map.

One way to check the redirect status, which is often used to block, is to enter the #002# code. This command cancels all types of redirects. While this is not a direct entry to the MIUI blacklist, it is a useful tool for resetting network lock settings if the phone is behaving strangely.

There is also a code for logging into the engineering menu, but it varies depending on the processor and Android version. Attempting to log in via ##4636## can open the testing menu, where in the "Phone Information" section you can sometimes find additional call management options, but the functionality there is limited and is intended for developers.

It is not recommended to use third-party codes found online without checking their relevance to your Redmi model.Incorrect resetting of settings through the codes can cause the phone to stop seeing the network or will constantly reset incoming calls from all subscribers.

Frequent problems and their solution

Despite the system's cleverness, users sometimes face situations where the blacklist is not working properly, such as blocked numbers continuing to pass, or conversely, calls from authorized contacts are not received, most often the problem lies in a conflict of settings or outdated software.

The first thing to do when a crash happens is to check the Security app's permissions. It must have access to the call log, contacts, and phone. Without those permissions, the system will not be able to analyze the incoming call and apply lock rules. Check this in Settings → Applications → Security → Permissions.

The second common reason is a conflict with third-party number identifiers, where if you have applications like Truecaller or Yandex with a determinant function, they can intercept call management, in which case the MIUI blacklist can be ignored in favor of the rules of the third-party application.

Also make sure that the phone has the latest firmware installed, older versions of MIUI may have bugs related to call processing, and system updates often contain fixes for security and stability of telephony.

Comparison of embedded tools and third-party applications

Many users are wondering whether to install additional applications to block, if Xiaomi Redmi already has built-in functionality? Let’s compare these two approaches so you can choose the best option for yourself.

MIUI's built-in tools are deeply integrated, consume minimal battery, do not display ads, and work consistently, and their main advantage is that they do not need the additional permissions that third-party programs require, but their spam number base may be inferior in coverage to specialized services.

Third-party applications like Kaspersky Who Calls or GetContact have huge databases that are being replenished by users around the world, which can identify a number even without the Internet (if the database is downloaded), but this comes at a cost of increased battery consumption and potential privacy risks, as you transfer your contacts to other servers.

For most Redmi owners, the built-in blacklist features are sufficient with Xiaomi’s updated base, which provides a balance between security, privacy and usability without the need to install extra software.
