Spam calls and intrusive offers from unknown subscribers have become a real problem for smartphone owners. Owners of the popular budget Xiaomi Redmi 8 often face the need to restrict access to certain contacts to their device. Fortunately, the MIUI shell offers powerful built-in tools to filter incoming calls and messages without installing third-party software.
In this article, we will take a closer look at where the locked list is stored and how to manage it correctly, and you will learn not only to view the blacklist, but also to set up smart locking rules that allow you to have full control over who might be bothering you.
The security settings interface may seem confusing due to the abundance of features, but we will go through all the steps consistently.This guide will help you understand the intricacies of the anti-spam module and effectively use its capabilities to protect your personal space.
Purpose and functions of the blacklist in MIUI
The lock function in Xiaomi smartphones is implemented at the system level, which ensures high efficiency. Unlike third-party applications, the built-in mechanism does not require additional permissions and works even in sleep mode, when other programs can be unloaded from memory.
When a number is on the lock list, the triggering hears the beeps or reset, but your phone is silent and does not vibrate.This is critical for maintaining concentration or rest.The system also keeps a log of blocked events, allowing you to check if necessary who tried to contact you while the ban was in effect.
⚠️ Warning: Blocked callers do not receive automatic notification that their number is blacklisted.
It is important to understand the difference between a full lock and a "Do Not Disturb" mode. If the first option cuts off only selected numbers or hidden identifiers, then the second mode can drown out all the sounds of the device.

The built-in blacklist of Xiaomi works autonomously and does not depend on the availability of the Internet, providing protection even in roaming.
Step-by-step: where to find the block list
To access the restriction management, you need to go to a special system application. On Redmi 8, it's usually pre-installed and it's called "Security." The icon is a green shield with lightning. This is where all the security tools of the device are concentrated.
Once you start the app, scroll down to the Antispam block, which is the part that filters incoming traffic, and you click on it, and you'll be taken to the settings menu, where you can see the statistics of blocked calls and messages, and in the upper right corner of the screen is the button with the image of the gear, which is the input to the configuration.
☑️ Checking the lock settings
In the settings menu that opens, you're interested in two main items: "Blacklist" and "Block": the first contains a list of numbers that are not allowed access; the second allows you to set rules, for example, block all hidden numbers or subscribers from other countries. To view a specific list, tap on the item "Blacklist".
Adding and removing numbers manually
Control of the database of prohibited contacts is intuitive. In the window that opens, you will see the current list of numbers. To add a new contact, click on the plus icon or the Add button at the bottom of the screen. The system will offer several options: choose from the contact book, take from the call history or enter the number manually.
When you manually enter, be careful: the number must be dialed in an international format (for example, +7 for Russia), otherwise the call filter may not work correctly.
To remove a contact from the list, just click on it and select the appropriate option in the menu that appears, often indicated by the basket or cross icon, and the feature is available to clean the entire list at once, which is useful if you temporarily enabled hard filtering.
- 📞 From history: A quick way to block a recent caller straight from a call log.
- 📒 From Contacts: Selecting a specific person from your phone book to limit your.
- ✍️ Manual Entering: The ability to enter any number, even if it is not in the phone memory.
Setting up smart rules and filters
The MIUI shell on Redmi 8 allows you to set up not only a dot lock, but also general rules. In the "Block" menu, you can activate the "Block Hidden Numbers" switch, which will save you from calling those who hide their ID. However, be careful: couriers or employees of organizations sometimes call from hidden numbers.
It also has a country-code lock feature, which means that if you're not waiting for calls from abroad, you can ban all international calls, and it effectively fights fraud centers in other regions, and it's in the same rule menu and it works in the background.
⚠️ Warning: Enabling the lock on all hidden numbers may result in missing important calls from doctors or emergency services staff using special identifiers.
Special attention should be paid to the setting "Keyword Blocking". It is relevant for the use of the Internet. SMS-You can ask for words such as "credit", "winning" or "promotion" and all messages containing them will automatically be hidden from the user's eyes.
How does the spam number database work?
Analysis of the blocked call log
Even if the phone was silent, it kept a record of all communication attempts, and the Security app has a log or a lock history section, and it shows all the missed calls and messages that were filtered by the system, so you can control the situation and not miss a really important call that could be mistaken for spam.
The log shows the time of the attempt, the phone number and the type of event (call or SMS) If you see an important number, you can quickly move it to the "White List" or simply remove it from black so you can call back.
Cleaning the log is separate from blacklisting, so you can keep your blocking history for months to analyze spammer activity if necessary, and the data doesn't take up much space and doesn't affect the speed of the Xiaomi Redmi 8.
Comparison of locking methods on Xiaomi
To better understand the differences between manual addition and automatic rules, consider a comparison table that will help you choose the best defense strategy for your case.
| Parameter | Manual blacklist | Blocking hidden | Lockdown in the country |
|---|---|---|---|
| Principle of action | Blocking specific numbers | Blocking everyone without ID | Prefix locking |
| Flexibility | High (point) | Low (all or nothing) | Average (by region) |
| Risk of missing a call | Minimum | High-pitched | Medium. |
| Need for updates | Only manually. | Automatically. | Automatically. |
As you can see from the table, combining methods is the best thing. Manually adding known spammers together with filtering hidden numbers creates a reliable shield. However, always leave the opportunity to communicate through the White List for the closest contacts.

Check the lock log once a week to make sure the system doesn’t hide important notifications from shipping services or banks.
