The problem of intrusive calls from scammers, spam or just unwanted interlocutors is familiar to every smartphone owner. Owners of Xiaomi and Redmi devices often wonder where exactly their gadget hides the number lock feature. Fortunately, in the shell of MIUI and the new HyperOS, this tool is built-in by default and does not require the installation of third-party applications.
Understanding where to look at the blacklist on the Xiaomi Redmi phone will allow you to instantly stop the flow of annoying signals. The filtering system works at the firmware level, which guarantees high efficiency and no advertising, which is often found in free analogues from the Play Market.
In this article, we will take a detailed look at all the ways to access the lock list, look at the nuances of working in different versions of the shell and answer frequent questions from users. You will learn not only to view blocked contacts, but also flexibly adjust the filtering rules for maximum comfort.
The main ways to access blocked numbers
There are several ways to get into the bans menu, and the specific method you choose depends on your habit and the version of the firmware installed, and the fastest way is to use the Security app, which is preinstalled on each device of the brand.
The second option is to log in through call settings, a method that is more traditional and familiar to those who have previously used other Android smartphones, both of which lead to the same result, allowing access to the lock list.
⚠️ Note: The menu interface may vary slightly depending on the version MIUI (12, 13, 14) or HyperOS, as well as from regional firmware (Global, EEA, CN).
If you can't find the right item in one place, try an alternative login method. Xiaomi preum! ascribes duplication of features for user convenience, so the tool you need doesn't go anywhere, it just changes the location.
💡
If you upgraded to HyperOS, the lock settings icon could move deep into the Security menu, but the functionality remained the same.
Search through the Security app
The most reliable and complete source of filtering settings is the System Security app, which is where all the device protection tools, including antivirus and traffic control, are concentrated. To begin, open the application with the characteristic green shield icon on your desktop or in the Tools folder.
Once you start the app, scroll down to the Tools or Antispam section. Depending on the location, this item may be called Blocker or have an icon with a crossed-out circle.
In the window that opens, you'll see the statistics of blocked events and the settings button, and there's the blacklist you want, where you store all the numbers you add, and there's the central control panel that allows you to edit the rules and prosmat! to tell the story.
- 🛡️ Open the Security app on the home screen.
- 📜 Find and select “Antispam” or “Blocker».
- ⚙️ Click on the gear icon or the “Settings” button in the corner of the screen.
- 📞 Select the Blacklist to view all blocked contacts.
It is through this section that it is most convenient to add numbers en masse or, conversely, to clear the list of mistakenly blocked subscribers, the functionality here is wider than when logging in through the call menu, since additional filtering options for SMS and hidden numbers are available.
☑️ Checking the lock settings
Entrance through the phone book and call menu
An alternative and often faster way to get to the desired section is to use the standard Phone or Contacts app, which is ideal when you need to urgently block the number from which the call just came, or check the list without looking for unnecessary icons.
Open the app you normally call through. In the upper right corner of the screen is a three-dot or three-bar menu (a hamburger menu), and clicking on it, you'll see a drop-down list of options, where one of the first lines is "Blocking Settings" or "Antispam".
In some versions of the MIUI shell, the path may look like Settings → Call Lock. Going this way, you will be taken to the same menu as the security app, and you will see the current lock status and the list of prohibited contacts.
This is particularly useful for quick work, for example, if you need to quickly add a number from your call history, you can do so without switching between applications. Just select a number in the history, click on it and select the option "Add to blacklist".
⚠️ Note: In some older firmware versions, the path may be called “Call Prohibit”, which is a complete synonym and leads to the same settings.
Remember that changes made through the call menu are instantly synchronized with the system security unit. You do not need to confirm additional actions - the filter will start working immediately after adding the number.
Managing a list of blocked contacts
Once you’ve found a blacklist on a Xiaomi Redmi phone, it’s important to learn how to manage it properly. This section shows all the numbers that are ignored by the system, and you can add new entries manually or delete existing ones.
To add a number manually, you usually have a plus button or a corresponding item on the menu, you enter the phone number in an international or local format, and Xiaomi's system allows you to block not only specific numbers, but entire ranges or hidden numbers.
Removing a contact from the list is also easy, and just click on the record and select Delete or use the Clear feature if you want to delete all the records at once, which is useful if you temporarily blocked everyone and now want to resume communication.
| Action. | Method of implementation | The result |
|---|---|---|
| Add a number. | The “+” button in the list menu | Number gets into lockdown database |
| Delete the number | Long pressing → Delete | The phone calls from the room will be back. |
| The hidden block | Hidden Numbers Switch | Calls are blocked without a determinant |
| History | The "Blocking Journal" tab | Viewing attempts to communicate from spammers |
Special attention should be paid to the Block Log function, which even if you don't see missed calls in the main phone book, this log stores information about who tried to reach you, which helps identify persistent spammers.
What happens to SMS from blocked numbers?
Filtering rules and exceptions
The blacklist functionality of Redmi smartphones goes beyond just a list of numbers, offering flexible rule settings to automate the protection process, and you can set the lock by keywords in SMS or by number type.
The Smart Lock option is often found in the anti-spam settings menu, and when activated, the phone itself analyzes incoming calls based on the spam database, which reduces the need to manually enter each new number of scammers.
Exception settings are also available, a critical feature that allows you to create a whitelist, and contacts made in exceptions can reach you even if their number is accidentally blacklisted or flagged as spam.
- 🔑 Keyword Blocking: Rejected SMS, containing certain phrases (e.g., “credit”, “winning»).
- 📞 Hidden number lock: complete call ignoring where no one is identified ID ringing.
- 📅 Do Not Disturb: Automatic activation of the blacklist at a specified time (at night).
- 🌏 Regional settings: the ability to select countries whose numbers should be blocked.
Competent settings allow you to create a virtually impenetrable barrier to unwanted communication, and it is recommended to periodically check the lock log to make sure that important calls are not screened out mistakenly.
Possible problems and solutions
Despite the system’s fine-tuning, users sometimes face situations where the blacklist doesn’t work properly, most often the problem lies in the settings of the Security app itself or in the Android system’s resolutions.
The first thing to check is whether the security app and spam database are updated. Anti-spam settings often have an Update button that loads the current signatures of the fraudsters' numbers, without which the smart lock may not recognize new call patterns.
The second common problem is conflict with third-party applications, where if you have other number detectors or blockers installed (for example, from antiviruses), they can intercept call management, in which case it is recommended to leave only the system tool MIUI.
⚠️ Note: After resetting your phone settings or updating your firmware, all manually added numbers can be deleted, so important contacts are best kept in a whitelist or a phone book marked.
If calls still pass, check to see if white-only (allowed) mode is activated, which can block everyone but a select few. SIM-Cards have funds, as some operators can block number determination services with a negative balance, which affects the operation of the filter.
💡
Xiaomi’s system blocker works at a deep level of OS integration, so third-party applications are often redundant and may even interfere with the proper operation of filtering.
