How to Include a Blacklist on Xiaomi: The Complete Guide

Xiaomi smartphone owners often face intrusive calls from spammers or unwanted contacts requiring immediate access restriction.built-in protection mechanisms in shells MIUI HyperOS allows you to effectively manage incoming traffic, blocking not only voice calls, but also intrusive calls. SMS-Modern antivirus algorithms integrated into the system work in conjunction with user settings, creating a reliable barrier to unwanted communication.

The activation process can vary depending on the software version and regional firmware of the device. In some cases, standard menus may hide advanced options that require an understanding of the logic of system security applications. Competent filter settings will allow you to forget about interrupting important meetings or vacations due to phone marketing.

There are several ways to restrict access for certain subscribers: through the built-in Security app, a standard “caller” or third-party utilities. Each method has its own characteristics and is suitable for different use cases, whether it is a one-time lock or create a permanent list of ignored numbers.

Use of the built-in Security application

The most reliable and functional tool for blocking management is the system application Security, which is preinstalled on each device of the brand. This is where the main traffic filtering algorithms, operating at a low level of the system and independent of third-party launchers, are concentrated. To start, you need to open an application with a characteristic green shield icon on your desktop or in the Tools folder.

In the application interface, you should find the section responsible for blocking calls and messages. Depending on the version of the MIUI shell, this item can be called "Antispam" or "Black List", and then you go to this section and you can access a detailed filtering rules setting, where you can activate the blocking of hidden numbers or numbers from other regions.

Adding a specific contact to the ignore list is done through a special control menu. You can manually enter a phone number, select it from the phone book or add the last missed call. The system will automatically apply the rules and begin to reject communication attempts without emitting beeps to the smartphone owner.

Importantly, the app's functionality allows you to flexibly adjust responses to incoming events, you can choose whether a subscriber will hear the beeps before resetting or the connection will be interrupted instantly, and you can also access the option of logging blocked events, which helps to track the activity of unwanted callers.

⚠️ Note: When you turn on Do Not Disturb mode in combination with a blacklist, lock notifications may not appear on the screen, but will be saved in the application log.

Blocking through the standard phone application

An alternative and often faster way to add a number to an ignorant list is to use a standard caller interface, which is convenient when you need to quickly lock the number immediately after an incoming call or viewing your call history. The interface may vary slightly depending on whether you use Google Dialer or a proprietary app from Xiaomi.

To perform the operation, you just need to open the call history and find the right contact. By clicking on the information icon (usually the letter "i" in a circle or an arrow), you will be taken to the subscriber card, where the additional actions menu (three dots) hide the desired function. Selecting the "Block" item will instantly enter the number into the system blacklist.

Google Dialer, which is often found on global firmware versions, offers additional protection against spam. Google algorithms automatically identify and flag suspicious numbers in red, warning the user of possible fraud.

Owners of HyperOS shell devices may notice the updated menu design, but the logic of the work remains the same: locking through the “call” synchronizes with the system security application, so it does not create duplicate rules and works stably in the background.

💡

Use voice input to quickly search for contact in your call history if the list is too long and manually time-consuming.

Advanced Spam Settings and Filters

Deep blacklisting allows you to create complex filtering rules that go beyond simply blocking specific numbers. The blacklist settings menu has switches available to block all hidden numbers, which is especially important in the fight against automated robotic callers.

Special attention should be paid to the message filter, which is often ignored by users: by enabling blocking SMS from unknown senders, you protect yourself from advertising mailings and phishing links.

Using keywords in message filtering is a powerful tool that allows you to block mailings containing phrases such as “credit”, “win” or “promotion”. By setting these parameters, you create a personalized shield that adapts to your current needs and the type of spam you receive.

Working with third-party applications and synchronization

In some cases, built-in tools may not be enough, especially if more complex functionality or cross-platform synchronization is required. Users often turn to third-party solutions such as Truecaller or GetContact, which have extensive spam databases. Integration of such applications with Xiaomi's system requires special permissions.

To properly operate a third-party blocker, you need not only to install the application, but also to set priorities correctly. Android limits the background activity of applications to save battery, so the blocker needs to be added to the exception list and issue call management rights. Without this, calls can pass, and lock notifications will not show.

Synchronizing blacklists between devices is possible through your Mi Account or Google profile, which allows you to save your lock settings when you switch to a new smartphone or after you reset your device to factory settings. Make sure that the synchronization settings select the appropriate points for contacts and system data.

⚠️ Warning: Third-party apps have access to your phone book. Use only proven programs with a good reputation to avoid leaking personal data.

When using third-party solutions, Xiaomi’s built-in blacklist can conflict with them, creating a double lock or, conversely, skipping calls. It is recommended to choose one main method of protection and disable duplicate functions in other applications for stability.

Managing a list of blocked contacts

Periodic blacklist revisions are an important procedure for maintaining order in communications, and over time the list may grow to include numbers that no longer pose a threat, or, conversely, important contacts may get there by mistake, managing the list through the same Security app or call settings.

To remove a number from the lock list, just find it in the lock list and press the unlock button (usually an open lock icon or cross). The system will instantly remove the restrictions, and the subscriber will be able to call you again. This action does not require rebooting the device or restarting services.

Newer versions of HyperOS have the option of group contact management, where you can select multiple numbers and perform a mass operation to add to or remove from the blacklist, saving you a lot of time cleaning your spam database after a long trip or a change of activity.

Also worth remembering is the existence of a whitelist, a list of contacts who can reach you even when full lock or Do Not Disturb mode is enabled, adding close relatives and colleagues to this list ensures that you remain available in critical situations.

💡

Regular blacklist checks help to avoid situations where important calls are lost among blocked numbers.

Typical problems and ways to solve them

Despite the system’s fine-tuning, users may find themselves in a situation where the blacklist is not working properly, calls pass, notifications are not coming, or blocked subscribers continue to bother, most often due to aggressive battery optimization, which kills the blocker process.

To solve the problem, you need to go to the battery settings, find the application responsible for blocking (Security or Phone), and set the “No Limits” mode. This will prevent the system from unloading the process from memory, ensuring constant monitoring of incoming traffic, and it is also worth checking for system updates, since new patches often fix errors in network modules.

If the problem persists, reset the app through the application management menu. It's important not to confuse resetting the app with a full phone reset - in the first case, you'll just return the call settings to the original one without losing your personal data. After the reset, you'll need to reconfigure the lock rules.

• 📱 Check if the “Airline” mode is turned on, which blocks all incoming connections.
• 🔋 Make sure the security application is not limited in background activity.
• 🔄 Restart the device after making changes to system settings.
• 📞 Check the relevance of the spam number database in the antivirus settings.

In rare cases, incorrect work can be associated with conflict. SIM-If you have two cards, try changing the settings for each. SIM-Cards are separate, as locking rules can be applied selectively to different slots.
