Smartphones line Redmi i Xiaomi are famous for their functionality, but searching for a specific setting in the shell MIUI or new HyperOS sometimes it turns into a real quest. One of these hidden features is managing a list of blocked contacts, which users often call a “blacklist”. The need to check this list arises when you stop receiving calls from important subscribers or, on the contrary, you want to make sure that intrusive spam is really blocked by the system.
Unlike “pure” Android, where blocking management is often scattered across different menus, in smartphones Redmi a separate system application is responsible for this. Security. It is this that accumulates all the traffic filtering tools, including blocking SMS and voice calls. Understanding the operating logic of this component will help you quickly find the necessary switches, even if the shell interface has been changed after the next update.
In this article we will examine in detail several ways to see the full list of blocked numbers. We will look at both standard methods through a graphical interface, as well as hidden USSD codes, which can be useful in non-standard situations. We will also pay attention to the nuances of operation anti-spam filterswhich can block calls automatically without adding a number to your personal blocking list.
Using the Security application to view the list
The main tool for managing blocking in smartphones Redmi is a system application that usually has a name Security and an icon in the form of a green shield. This is not just an antivirus, but a central hub for setting up privacy. To get to the desired section, you don’t need to look for settings in the phone’s deep menus; It is enough to launch this particular system component, which is preinstalled on all devices of the brand.
After launching the application, pay attention to the upper part of the screen or the lower toolbar, where various modules are located. We are interested in a section that may be called Antispam, Blocking or have an icon that resembles a list with a prohibitory sign. In different versions of the shell MIUI the location of this element may vary, but it is always located within the main screen of the "Security" application.
⚠️ Attention: The interface of the "Security" application may differ in depending on the firmware version and installation region. If you don’t find the “Antispam” item right away, try clicking on the three dots in the corner of the screen or the “More” button to expand the full list of tools.
Inside the blocking management section there are usually several tabs. We are interested in the list of blocked numbers, which is often hidden behind the settings button or a separate “Blacklist” tab. All contacts that you added manually or automatically using filtering rules are displayed here. It is in this menu that you can edit the list, delete numbers or add new exceptions.
Navigation through the standard Phone application
There is a faster way to access the list of blocked contacts that does not require launching a separate application. The standard dialer on smartphones Redmi also has built-in call management tools. To do this, open the application Phone and find the menu button, which is usually represented by three dots or horizontal bars in the upper right or lower corner of the screen.
In the drop-down menu, select the item Settings or Blocking numbers. In some versions of the shell, this item may be called “Antispam” or “Call Filter”. By going to this section, you will see a “Block numbers from the blacklist” switch and a button to view the list itself. This method is especially convenient since it is integrated directly into the dialing interface.
If you are using a modern version HyperOSthe path may be slightly different. In such cases, the system often prompts you to go to the blocking settings through the user profile or a special privacy section. It is important not to confuse blocking specific numbers with the Do Not Disturb function, which works on a different principle and temporarily hides all notifications.
What is the difference between blocking and Do Not Disturb mode?
Blocking in the black list works constantly and regardless of the time of day, completely cutting off calls from selected subscribers. Do Not Disturb mode is a temporary phone state that ignores sounds and vibration from all contacts (except favorites), but does not prevent the call from entering the log unless configured otherwise.
Checking the list through the “dialer” allows you to quickly add a just received missed call to the black list. To do this, just open the call log, click on the number or contact and select the appropriate option. However, to view the full list of all blocked subscribers, it is still recommended to use the method described above through the “Security” application, as it provides more advanced functionality.
Searching for blocked contacts through System Settings
The third way to get to the treasured list is through the general settings of the smartphone. This method may seem less obvious, but it guarantees access to system filtering rules that apply globally to all communications applications. Open the main settings menu Redmi and use the search bar at the top of the screen.
Enter the keywords in the search: blacklist, blocking or antispam. The system will automatically highlight the corresponding menu items. Clicking on the found link will immediately open the desired call settings section. This is especially true for new versions of Android, where the menu structure can be significantly changed compared to previous generations of devices.
An alternative path through the system settings is as follows: go to the section Applications, find the system application in the list Security or Services and feedback (depending on the MIUI version). Inside the settings of this application you can also find links to manage blockers. This approach is useful if standard icons on the desktop have been removed or hidden.
☑️ Checking lock settings
It is worth noting that in some regions (for example, in global firmware versions for Europe) the names of items may be translated differently. If searching for "block" doesn't return any results, try searching for "spam" or "filter." The system logic remains the same, but the linguistic nuances of localization can confuse an inexperienced user.
Using USSD codes and hidden menus
For advanced users who prefer quick commands, it is possible to use USSD codes or engineering menus. However, unlike push-button phones of the past, modern smartphones Redmi do not have a single universal code that would display a list of blocked numbers in text form. Instead, codes are used to activate or deactivate operator services.
However, there are codes to check the forwarding status, which is often used as an alternative to blocking. For example, dialing a code #002# allows you to disable all types of forwarding, which can be useful if the blocking was set up through your telecom operator and not through your phone. To view call settings through the engineering menu, you can try to enter ##4636##, but this menu is intended primarily for testing networks and batteries.
It is important to understand the difference between blocking at the device level and blocking at the operator level. If the number is blocked through the operator’s services (for example, “Antispam” from a mobile provider), then you will not see it in the phone menu Redmi e. In such cases, you must use the USSD commands provided by your telecom operator or your personal account.
⚠️ Attention: Do not enter unknown USSD codes found on the Internet without checking their purpose. Some codes can reset network settings or activate paid services. Use only standard commands to check the status.
If you are faced with a situation where calls are not going through, but the number is not on the phone’s black list, check the status of the Caller ID or Antispam service with your operator. Often it is network filters that cause calls to “miss”, and you don’t need to look for them in the settings Android, and in the operator's service menu.
Differences between a manual list and an automatic filter
When analyzing blocked numbers on Redmi it is important to distinguish between two types of blocking: manual (your personal blacklist) and automatic (anti-spam filter). The manual list contains numbers that you have added yourself. The automatic filter is based on cloud-based databases and algorithms that flag numbers as “Advertising,” “Telemarketing,” or “Scammers.”
The automatic filter can block calls even if the number is not on your personal list. In the application Security these categories are separated. You may see that the total blocked call count is high, but the manual list will be empty. This means that the work was done by an intelligent protection algorithm.
Regularly check the log of blocked calls in the Security application. Sometimes important numbers (for example, from courier services or doctors) that were mistakenly marked as spam by the database end up there.
Configuring antispam sensitivity allows you to control which categories of numbers will be blocked automatically. You can allow calls from delivery services, leaving the blocking only for scammers. This flexibility makes the security system MIUI one of the most effective, but requires periodic user attention to adjust the rules.
The table below compares the main characteristics of the two types of blocking for a better understanding:
| Characteristics | Manual blacklist | Automatic antispam |
|---|---|---|
| Data source | User (you) | Cloud database and algorithms |
| Flexibility | Full control over each number | Depends on category settings (advertising, fraud) |
| Update | Only manually | Automatically via the Internet |
| Impact on the battery | Minimal | Requires periodic database updates |
Frequent problems and their solutions
Users Redmi sometimes encounter with a situation where a number added to the blacklist continues to call. Most often this is because the lock was not saved due to an application crash or a permissions conflict. Make sure that the application Security has all the necessary permissions to work with contacts and call logs.
Another common problem is the inability to remove a number from the list. If the delete button is greyed out or the list isn't updating, try clearing the Security app cache. To do this, go to Settings → Applications → All applications → Security → Memory and click Clear (clean, not delete the application). This will not affect your personal data, but will reset the temporary files of the app.
It is also worth mentioning the synchronization problem. If you use an account Mi Account or Google to synchronize contacts, changes to the blacklist may not be applied immediately. In such cases, it is recommended to reboot the device so that the system applies the new traffic filtering rules.
If blocking does not work, first check if the number is in the “White List” (Favorites) list, as it has priority over the black list.
In rare cases, blocking may not work due to the use of third-party caller ID (for example, Truecaller or Yandex with ID). These applications can hijack call control. If you use such services, it is better to make blocking settings directly within them, and not through standard means MIUI.
Additional call management features
The blocking functionality on smartphones Redmi is not limited to simply barring calls. The system allows you to configure the blacklist schedule. For example, you can activate blocking of all unknown numbers only at night or on weekends. This is done through the settings menu inside the “Antispam” section.
The “Guest Mode” function or temporary unblocking is also available. If you are expecting an important call from an unfamiliar number, but do not want to disable protection completely, you can use temporary exceptions. This is especially true for those who are expecting a call from a courier or a potential employer.
Do not forget that blocked subscribers hear beeps, as if there is a call, but your phone is not ringing. For them, the situation looks like a normal reset or no response. Some operators can broadcast a voice message about unavailability if this is configured in the tariff.
What does the caller see when he is on the black list?
The caller hears long beeps, after which the call is interrupted. In some cases (depending on the operator and the type of blocking), he may hear the message “Subscriber is busy” or “Not available.” The caller does not receive any special notification that he is on the black list.
Using all the capabilities of the filtering system allows you to create a comfortable sound environment. Proper setup blocking rules will relieve you of nervous tension and save battery power, which is often wasted on processing spam calls.
FAQ: Frequently asked questions
Can a blocked subscriber leave a voicemail message?
Yes, if you have voice mail service enabled from your operator, the blocked subscriber will be able to leave a message. Blocking at the phone level Redmi interrupts the sound signal and vibration, but does not cancel the services of the telecom operator. To completely exclude a contact, you need to block the number through the operator.
Where is the history of blocked SMS messages stored?
The history of blocked SMS messages is located in the same application Security, in the "Antispam" section. There is a separate tab for messages. Please note that the content of such messages may not be viewable depending on your privacy settings, but the sender's number will be visible.
Is the blacklist reset when you reset your phone to factory settings?
Yes, a full device reset (Factory Reset) will remove all local settings, including the manually created blacklist. However, if you used synchronization with Mi Cloud or account Google, the list may be restored after authorization.
Why are some numbers from China or other countries not blocked?
International numbers may have a complex format, which the system does not always correctly recognize as spam. To reliably block such numbers, it is recommended to use blocking masks (for example, blocking all numbers starting with +99...) or third-party identification applications with global databases.
How to add several numbers to the blacklist at once?
Standard means MIUI mass addition is not possible - only one at a time. For batch adding (for example, from a contact list), the easiest way is to use third-party call management applications or export contacts to a file and use specialized scripts if you have the skills ADB.
