Owning a Xiaomi smartphone opens up a lot of personalization options for the user, but it also requires understanding the specifics of the MIUI shell or the new HyperOS. One of the popular features for many owners is the management of unwanted calls, but the system interface sometimes hides these settings quite deeply. If you are looking for where to look at locked numbers on Xiomi Android, the standard phone book does not always give exhaustive information immediately after opening.
The problem of finding a list of ignored contacts often arises because the logic of the Security app and the standard Phone may have been different in different years of device release. The blacklist in the Xiaomi ecosystem is not just a list of exceptions, but part of a comprehensive spam protection system, which is why it can be found through several different paths, each leading to the same result but requiring a different sequence of actions.
In this article, we will take a look at all the ways you can detect and edit a block list, learn how to access the settings you need through the call menu, through the central security service, and even using secret codes, and understand these mechanisms will allow you to effectively filter incoming traffic and block intrusive advertisers or scammers.
Search for blocked contacts through the phone application
The most obvious and logical way to find a list of ignored subscribers is to go to a standard app to make calls. Most modern Xiaomi, Redmi and Poco models use either a standard Google Dialer or a proprietary MIUI Dialer. The interface of these applications has a similar structure, but the names of items can vary slightly depending on the firmware version.
To get to the menu you need to run the Phone app and find the three-dot or horizontal button that is usually located in the top right corner of the screen. Clicking on this item will open the drop-down menu where you should select Settings. This is where the basic call settings, including lock management, are hidden. It is important not to confuse these settings with the general smartphone settings, which are in the gear on the desktop.
Inside the settings menu, you'll need to find a section that can be called "Block" or "Blocked Numbers." In some versions of the shell, this item is placed in a separate category "Antispam." Going down this path, you'll see a complete list of all the numbers that the system automatically rejects when you try an incoming connection.
💡
If you don’t see the “Block” option right away, try scrolling down the settings list – sometimes it’s hidden under the optional “Additional” or “Extended Settings” menu.
The list interface typically allows you not only to view the numbers, but also to manage them quickly. You can add a new number manually by clicking on the corresponding button, or delete an existing one by swiping a line or using an edit button, which gives you complete control over who can reach you and who will receive a "busy" or reset signal.
Using the Security App to Manage Spam
A unique feature of Xiaomi smartphones is the presence of a pre-installed system application called Security, which is not just an antivirus, but a powerful combine of memory cleaning, access control and, importantly for our theme, call filtering, which is where the most complete statistics and lock settings are stored, especially if you use older versions of MIUI.
To access the blocked number list through this tool, look for an icon on your desktop called “Security” and a green shield. After you run the app, scroll down to the “Blocklist” section. In some cases, this module may be called “Antispam”. Clicking on it, you will be taken to the filter control center, where you can see not only the numbers, but also the history of blocked SMS-message.
Inside the Blocker, the interface offers flexible settings, you can switch between the Blocked, History and Settings tabs. The Locked tab contains a static list of numbers that you or the system have added to the ignorant list, and there is often a feature for adding numbers from the call log or contacts with one touch.
☑️ Checking the lock settings
The advantage of using the Security app is that there are additional filters, such as locking all hidden numbers or numbers that start with a specific prefix, which is especially useful for combating robot callers that change numbers but leave the same city or operator code.
System settings and menus SIM-map
Sometimes users search for a lock list in general Android system settings, believing that it is a global parameter of the device. MIUI But there's a way through system settings that allows you to control behavior. SIM-Cards, including blocking incoming.
To find this section, open the Settings of your smartphone, then go to Apps or System Apps. Find Phone in the list and click on it. Next, select Call Settings or Settings. SIM-There may be switches that are responsible for forwarding to voice mail or blocking under certain conditions, although the full list of numbers here is rarely displayed.
A deeper level of settings is linked to operator services, and some locking functions (e.g., Inbox Prohibit) are implemented at the network level and managed via the Settings menu» → «SIM-maps and mobile networks» → «Additionally» → «Blocking incoming calls. This menu often requires input PIN-code provided by the operator, and not specified by the user.
What is the difference between a lock on the phone and the operator?
It is worth noting that the settings associated with PIN-Lock codes are a more serious security tool, but less convenient for day-to-day management of specific numbers, designed to be completely line isolated, rather than a selective contact filter. Therefore, for everyday use, it is better to rely on the first two methods described.
Use of the USSD-codes and secret commands
For advanced users who prefer quick access to hidden features, there are special codes. Xiaomi smartphones and other Android devices have a universal code that allows you to instantly go to manage the list of ignored numbers, bypassing long searches on the menu.
Open the Phone app and enter the following character combination:
##4636##This code opens a hidden engineering testing menu. However, some firmware versions may require a different approach to directly access the blacklist or use the ##86583## code, which forcefully includes displaying the lock button in the contact profile. But the most direct way to see the list is by using a forwarding code or lock status, although these often depend on the operator.
A more reliable “secret” method is to use a code to check the lock status of all incomings, which often looks like #33# or #43#. These commands show the status of services on the operator’s side. To view the user list on Xiaomi, the most effective “code” remains a quick transition along the Settings path → Apps → Phone → Call settings → Locked numbers, which can be taken to the widget.
It is important to understand that secret codes may not work on newer versions of HyperOS or in certain regions for security reasons. If you don’t get anywhere, use the standard graphical interfaces described in the previous sections – they work on all current devices.
Table: Comparison of blocking management methods
To organize the information and choose the most convenient way for you, we have prepared a comparison table that will help you quickly orient yourself, which method is better suited for a particular task: a one-time check, mass removal or fine-tuning of filters.
| Method | Wherever | Convenience | Functional |
|---|---|---|---|
| Application Phone | Menu → Settings → Blocking | High. | Basic list, quick addition |
| Security Annex | Locker → Blocked. | Average. | Extended filters, SMS statistics |
| System settings | Settings → SIM-map | Low. | Global blocking of services |
| Contact card | Contacts → Choice of contact → Menus. | High. | Blocking a particular person |
As you can see from the table, the Phone and Security app provide the most complete access to list management. SIM-The cards are more like tariff options than a personal blacklist, and the use of a contact card is ideal when you need to quickly block one particular intrusive interlocutor.
Frequent problems and their solution
Despite the cleverness of the system, Xiaomi users may experience situations where locked numbers still pass, or, conversely, important calls are lost. One of the common reasons is synchronization with a Google or Mi Account account. If you changed your phone but did not update the lock list in the cloud, the new settings may not apply.
Another problem is with system updates: After switching from MIUI 13 to 14 or HyperOS, the menu structure may have changed and the old ways stopped working, so you can search by settings: click on the magnifying glass at the top of the Settings screen and type in the "Block" or "Blacklist" request.
Why can a blocked number be called?
It's also worth checking if Do Not Disturb (DND) mode is enabled, which allows the phone to reset all but a select few, giving the illusion of a blacklist, although a different mechanism actually works. Make sure that the DND mode settings don't tick "Block All" if you want to see those missed from strangers.
