How to block contact on Xiaomi phone: the complete guide

Spam calls and intrusive offers have become a real scourge for owners of modern smartphones. Owners of Xiaomi, Redmi and Poco devices often wonder how to effectively protect themselves from unwanted communication using the built-in capabilities of the system. Fortunately, the MIUI shell and the newer HyperOS provide powerful tools to filter incoming calls and messages without the need to install third-party applications.

The locking process can vary depending on the version of the Android operating system and the specific interface modification installed by the manufacturer. In some cases, standard methods may differ from the usual algorithms, especially if the device was purchased on the global market, rather than at official retail. Understanding these nuances will allow you to quickly set up a blacklist and forget about annoying calls.

In this article, we will take a closer look at all the ways you can limit your connection to certain numbers, look at both the standard tools and the specific features that are specific to the Xiaomi ecosystem, and learn not only to block individual contacts, but also to hide the notifications of missed calls from them, ensuring complete digital peace.

Standard lock through call log

The fastest and most obvious way to stop calls from a particular subscriber is to use call history. This method works the same on most versions of MIUI and is suitable for situations where you need to urgently lock the number from which the call just came.

Find the number or contact you want in the recent call list, click on it to reveal details about the call, or simply tap the information icon (the letter "i" in the circle) next to the number. In the menu that opens, you need to find an item that can be called "Block", "Block" or have an icon of a crossed circle.

The system will request confirmation of your action, this is done to prevent the accidental blocking of important contacts, after confirmation, the number will be entered into the ignore list, and any subsequent attempts to contact you from this number will be automatically rejected by the system without your participation.

It is important to note that once blocked, you will not receive any notification of attempts to call. For the blocked subscriber, the phone will sound as "busy" or reset the call after the first beep, depending on the operator's settings.

Set up a blacklist through the Security app

In Xiaomi devices, the central node of management is the Security app, which is where the most flexible traffic and call filtering settings are concentrated, and this method allows you to not just lock a single number, but create complex rules for entire groups of contacts.

Launch the Security app with a green shield icon. In the tool menu, look for the Antispam (or “Block”) section. Here you will see statistics of blocked calls and messages, as well as access to the blacklist settings. By clicking on the Blacklist button, you will be taken to the Unauthorized Numbers Management menu.

• 📱 Click on the plus icon or the "Add" button to manually enter the number.
• 📞 Choose a contact from your phone book if it is already stored with you.
• 📋 Import a list of numbers from your call or message history.
• ⚙️ Set up a lock profile (only calls, only) SMS or).

The MIUI feature is the ability to choose which type of lock you can set up so that calls from certain numbers don't go through, or to make them block at certain hours, which is especially useful for limiting contact with telemarketers in the evening.

⚠️ Note: When you add a number to the blacklist through the Security app, make sure you select the correct profile. SMS", The calls will be free to go.

Blocking directly from contacts

If the number is already saved in your phone book, the locking process becomes even more intuitive: Open the Contacts app and find the right person. Click on the contact name to go to his card with detailed information.

At the top of the screen or in the menu behind the three dots (or the "More" button) should be a switch or "Block" item. In some versions of HyperOS, this switch is placed prominently just below the contact avatar, activating this switch instantly enters the number in the system blacklist.

The advantage of this method is that you can see who is locked right away. Unlike the number list in the security application, here the lock is tied to a name, which makes it easier to manage the list of banned persons. You can always unlock the contact by simply returning the switch to its original position.

Keep in mind that syncing contacts with a Google or Mi Account does not transfer the lock status to other devices. If you block a contact on your phone, it will remain available for calls on a tablet or other smartphone that uses the same account.

Use of operator codes and hidden functions

In addition to the software settings of the smartphone itself, there are methods of locking at the operator network level, which can be useful if you need to lock a number that is constantly changing (spoofing), or if you want to limit access to your number completely. However, for blocking specific incoming are more often used USSD-codes or settings through the operator’s personal account.

Some users are looking for hidden menus, such as MIUI Daemon or engineering menus, for deeper customization. However, using the ##6484## engineering menu or similar codes to block contacts is not recommended, as this can lead to system work instability.

For mass blocking, you can use forwarding codes. For example, the command **67*number# (syntax can vary between operators) allows you to hide your number or redirect calls. But for simple blocking of incoming from a particular person, it is better to use built-in Android functions, which do not require knowledge of complex codes.

Blocking Unknown and Hidden Numbers

A separate problem is calls from unknown numbers or when a subscriber hides his or her ID. MIUI has a feature called "Block Unknown Numbers" that is located in the settings of the Phone application or in the Antispam section.

By activating this option, you will be able to block any calls that are not numbered by the system, and be careful that this can cut off not only spam, but also calls from couriers, taxis or doctors using corporate communications with a hidden number.

• 🚫 Open the call settings in the Phone application.
• 🔍 Find the "Block" or "Antispam" section".
• ✅ Activate the switchboard "Block unknown numbers".

It is also possible to block all international calls if you don’t wait for calls from abroad, which often helps reduce the amount of robotic spam that often comes from foreign codes.

💡

Periodically check the list of blocked numbers. Over time, old contacts may accumulate there, the blocking of which is no longer relevant, and you may forget about an important call.

Frequent problems and their solution

Sometimes users are faced with a situation where a blocked contact can still be reached, this can happen if a third-party calling app (such as Google Phone) is installed on the phone, which has its own blacklist settings, different from Xiaomi's system.

In this case, you need to open the settings of the Google Phone application itself (three dots → Settings → Locked numbers) and duplicate the lock there. Conflicts between the MIUI system call and the standard Android caller are a common cause of “holes” in protection.

Another problem can be a crowded lock list. Although the limits are high, in rare cases, old firmware may have had limits on the number of records. If you encounter errors, try clearing the list of old, irrelevant entries.

⚠️ Note: If you have changed your phone book or upgraded to a new version of Android, your blacklist settings may reset.Always check the up-to-date list after major system updates.

💡

Double check settings in the Google Phone app and MIUI system call guarantees 100% protection against unwanted calls.
