How to open a blacklist in your Xiaomi phone

Every smartphone owner has a powerful tool to combat this problem: a built-in call blocker that allows not only to ignore calls, but also completely hide their presence, ensuring silence and calm. To effectively manage unwanted contacts, you need to know where exactly this functionality is hidden in the system.

The interface of the MIUI shell or the new HyperOS may vary from version to version, but the logic of the system applications remains unchanged. The blacklist is integrated directly into the Phone and Messages app, which eliminates the need to install third-party programs. Understanding the menu structure will help you quickly find the right settings in any situation, even after updating the firmware.

In this article, we will take a look at all the ways to access the block list, not only by adding numbers manually, but also by setting up smart filters that automatically screen out ads, and by making contact management a simple and easy process to keep your smartphone under full control.

Access via the standard call app

The fastest way to get into lock settings is to use a regular caller, which is where most incoming calls go, so it makes sense that filter management is here. Open the Phone app and look at the dialing interface.

In the upper right corner of the screen, you'll see a three-point icon or a gear image, depending on the version of the shell. Clicking on this element opens a context menu where important system options are hidden. You'll need to select Settings or Call Settings.

In the menu that opens, look for a section called Lock or Antispam, which can be red or have a special shield icon, and that's where all the tools for filtering incoming traffic are concentrated.

⚠️ Note: In some regions (e.g. Indonesia or India) due to local legislation, blocking functions may be hidden or removed from standard firmware.

If you don't find the right item, you may not have your region set in the phone settings correctly, and changing the region to Russia, Ukraine, or Kazakhstan often returns access to the full functionality of the blocker.

💡

If the “Block” item is missing, try clearing the cache of the “Phone” application through the smartphone settings, but do not delete the data so as not to lose the call history.

Settings through the Security app

An alternative and deeper layer of lock management is found in the system application Security. It has a green icon with a shield and is pre-installed on every Xiaomi, Redmi and Poco device. This method gives access to advanced settings that are not visible in the regular call menu.

Run the app and find an icon that says Antispam, which is usually located in the bottom row of the menu or in the main tool block, and inside this section is a full database of blocked numbers and logs of intrusion attempts.

And you can see not only the manual blacklist, but also the automatic filters, and it analyzes incoming calls and messages by checking them against the cloud database of spam numbers, and by clicking on the gear in the corner of the screen, you'll be able to get into the detailed filtering rules settings.

• 🛡️ Keyword Blocking: Banning posts containing certain phrases.
• 📞 Hiding Numbers: Blocking All Calls from Hidden Subscribers.
• 🌍 Blocking by country code: banning calls from certain regions.
• 👤 Contacts only: White List mode, which only allows familiar numbers to be accessed.

The use of the Security app is preferable for fine-tuning the protection, allowing you to create complex scenarios that work even in the sleep mode of the device.

Adding numbers to the blacklist

There are several ways to isolate an unwanted subscriber, and the easiest way is through a call history: find a number on a recent call list, click on it, and select Add to a blacklist. The number will be locked instantly.

If the number hasn't called you yet, but you want to block it proactively, use manual input. From the lock menu, select Add and enter the phone number. This is useful when you're changing your SIM card and want to move old locks.

You can also block contacts directly from the phone book, open the person's card, scroll down and find the switch or lock button, and then all calls and SMS from that contact will be ignored by the system.

It is important to understand that the lock works two-way: you will not see calls from this person, and he will not receive a notification that his number is blocked (he will have a horn, as in a normal call).

Communications and SMS-spam

The blacklist on Xiaomi phones works effectively not only with voice calls, but also with text messages. Advertising and phishing SMS often become an irritant than calls.

In the message blocking settings, you can activate the keyword filter, for example, by adding the words "credit," "win" or "promotion," you automatically hide any messages containing these terms, a powerful tool for cleaning up junk traffic.

The blocked messages are not permanently deleted, but are moved to a special folder. To check if something important has hit there, go to the Messages app, click on the menu and select Blocked Messages, which stores the history of all filtered SMS.

It is worth noting that the lock in the standard blacklist does not apply to messengers (Viber, Telegram, WhatsApp), for which you need to use the internal privacy settings of each particular application.

Removal from the blacklist and unblocking

Life situations change, and sometimes you have to unblock the contact. The unlocking process is simple, but it takes care not to accidentally delete important data. Go back to the Antispam menu or lock settings in the call app.

Go to the blocked number list. This shows all the contacts you previously made on the ignorant list. Click on the number you want to unlock, and select the option to Delete or Unblock. Confirm the action in the pop-up window.

Once the number is removed from the blacklist, the caller will be able to call you again, no additional phone reboots are required, the changes take effect instantly.

⚠️ Warning: When cleaning the blacklist, be careful with the "Clear All" button, which removes all the numbers from the lock list at once, and it will be difficult to manually restore them.

If you’ve used keyword filtering, be sure to check this section too. Deleting a word from the stopword list will resume receiving messages containing that phrase.

💡

Regularly checking the blacklist helps avoid a situation where you accidentally block an important number (such as a courier or doctor) and miss an urgent call.
