Protecting personal space in the modern digital world is becoming a critical task for every smartphone owner. Unwanted calls from spammers, intrusive messages from ex-partners or simply annoying interlocutors can seriously disturb your peace and productivity. In the ecosystem, the solution to this problem is implemented quite flexibly, however, the interface of the shell Xiaomi the solution to this problem is implemented quite flexibly, but the shell interface MIUI or a new one can confuse an inexperienced user. HyperOS may confuse an inexperienced user.
The process of isolating an unwanted subscriber does not require the installation of third-party software, since all the necessary tools are built deep into the system. Correctly setting up a blacklist allows you not only to block voice calls, but also to completely filter out incoming messages, leaving your correspondence history untouched for you, but hidden from the eyes of the sender. We will analyze in detail all available methods, from standard settings to specific security functions.
Standard blocking via the Phone application
The fastest and most obvious way to stop receiving calls from a specific number is to use the built-in functionality of the application Phone. This method is ideal if you urgently need to block a caller immediately after a conversation or after a missed call. The interface may differ slightly depending on the firmware version, but the logic of actions remains the same for all devices of the brand.
First, open the call log and find the desired number in the list. Click on the information icon (usually a letter i in a circle or a right arrow) next to the number. In the contacts menu that opens, scroll down to the very bottom of the screen. There you will find a red button or an item with the inscription Block. After clicking, the system will ask you to confirm the action.
It is important to note that in some versions of the shell, when blocked, a pop-up window appears with additional options. You may be offered not only to prohibit calls, but also to block SMS messages from this subscriber. Ignoring this checkbox will result in text messages continuing to arrive on the device, albeit in a hidden folder. Be careful when choosing blocking options.
⚠️ Attention: After blocking a contact through the standard menu, the subscriber will hear short beeps or a message that the number is busy, depending on the settings of your telecom operator. The sender will not receive any notifications about blocking.

Configuring a black list in the Security application
More advanced control over incoming traffic is carried out through the system application Security, which is the central hub for managing settings in Xiaomi. Here you can not only add specific numbers, but also set up rules for entire groups of subscribers, for example, block all hidden numbers or contacts not saved in the phone book.
Launch the application Security and find the section Antispam. It is usually located in the toolbox or accessible through the menu in the form of three dots in the corner of the screen. Inside this section there is a tab Black list, where all blocked numbers are displayed. To add a new element, click on the plus icon or the button Add at the bottom of the screen.
The system will offer several options for adding: from the call log, from contacts or manually entering a number. When entered manually, you can use masks to block entire ranges of numbers, which is especially useful when combating telephone scams that use similar combinations of numbers. This is a powerful tool for filtering unwanted traffic at the system level.
Use the keyword blocking function in the Antispam section to automatically hide messages containing phrases like "credit", "win" or "casino".
Inside the blacklist settings, an item is also available Settings (gear), where you can adjust the behavior of the device when receiving blocked call. You can choose whether the phone will answer the call at all (complete silence) or reset it and send a busy signal. Correct configuration of these parameters will help to avoid unnecessary questions from the blocked person.
Blocking through the Contacts menu
If the unwanted caller is already saved in your phone book, the most logical solution would be to manage his status directly through the contact card. This method is convenient because it allows you to visually see the blocking status directly in a person’s profile, without switching between different applications.
Open the application Contact and find the desired person by name. When going to the detailed description of the card, pay attention to the top of the screen or the menu hidden under the three dots. In modern versions MIUI the option Block is often placed in a separate action block along with the call and message buttons.
After activating the blocking, the phone icon in the contact card may change or be crossed out, signaling that the connection with this subscriber broken. That deleting a contact from the phone book does not automatically block it. If you simply delete the entry, but the number remains in the call history, the call will still go through unless it is added to the blacklist separately.
| Blocking method | Call blocking | SMS blocking | Ease of access |
|---|---|---|---|
| Via Call Log | Yes | Optional | High |
| Via Antispam | Yes | Yes | Average |
| Via Contact Card | Yes | Yes | High |
| Manual number entry | Yes | Yes | Low |
Hide messages from blocked numbers
Many users are faced with a situation where calls are blocked, but spam messages continue to alarm with notifications. The system has a separate mechanism for processing such messages, which redirects them to a special folder without displaying them in the main conversation list of the application. Click on the menu (three dots) and select Xiaomi there is a separate mechanism for processing such messages, which redirects them to a special folder without displaying them in the main application correspondence list Messages.
To make sure messages are truly hidden, go to your messaging app. Click on the menu (three dots) and select Blocked or Blacklist. All text messages from numbers included in the ignore list will be accumulated here. You can view them at any time, but they will not make a sound or vibrate when received.
There is an important way this feature works: if you decide to unblock a contact, old messages will not automatically move to your inbox. They will remain locked in the archive until you manually delete them or restore them. This protects the user from a sudden influx of old spam after changing the solution.
⚠️ Note: The Messages app interface may differ depending on whether you are using the stock MIUI app or Google Messages. In the Google application, the path to blocked messages is in the menu → Spam and blocked.
For maximum privacy, it is recommended to regularly empty the folder with blocked messages. Although they are not visible on the home screen, they take up space in the device's memory and can theoretically be read if someone gains access to your phone and knows where to look for hidden content.
What does the blocked subscriber see?
When you block a number on Xiaomi, the sender does not receive any special notification about it. His calls are simply dropped or become busy, and messages are delivered to the server but are not displayed to you. For him, the situation looks as if the phone is turned off or is out of network coverage.
Blocking unknown and hidden numbers
One of the most annoying problems is spam from unknown numbers that are constantly changing. It is impossible to manually block each new number, so the developers Xiaomi implemented the function of blocking all calls from subscribers not saved in contacts, as well as from hidden numbers.
Activation of this function is in the same section Antispam applications Security. Go to the blacklist settings and find the switch Block calls from unknown numbers. When you enable this option, the phone will automatically reject any calls if the caller's number is not in your phone book.
Using this feature requires caution, as it may block important calls from couriers, doctors, or potential employers whose numbers are you're not there yet. It is recommended to use this mode only during periods of increased spam or when complete silence is a priority. For hidden numbers (when a subscriber deliberately hides their ID), blocking is usually turned on by default and is the most secure option.
Blocking all unknown numbers is a drastic but effective measure against spam, but it can lead to missing important business calls.
Possible problems and their solutions
Sometimes users are faced with a situation where a seemingly blocked number continues to call or send messages. Most often this is due to the fact that the blocking was applied only to voice calls, and the SMS filtering setting remained inactive. Check the checkboxes in the menu for adding a number to the blacklist.
Another common reason is the subscriber’s use of Internet messengers (WhatsApp, Telegram, Viber). System blocking of the phone does not apply for these applications. To stop communicating there, you need to go to the settings of each specific messenger and block the contact within it. These are different levels of protection that do not duplicate each other.
It is also worth considering the peculiarities of the work of telecom operators. If you have blocked a number, but the caller uses the Caller ID service or the call is made through IP telephony with a number spoofed, the system may not recognize the source of the call as blocked. In such cases, only complete blocking of all unknown numbers helps.
⚠️ Attention: After resetting the phone to factory settings or when transferring data to a new device, the blacklist settings may be lost. Always check that your block list is up to date after a migration or software update.
