Constant calls from intrusive advertising agents, scammers or simply unknown subscribers can anger even the quietest person. Xiaomi smartphone owners often face this problem, as the popularity of the brand attracts the attention of spammers. Fortunately, the shell MIUI and HyperOS have powerful built-in tools to combat unwanted calls.
In this article, we will take a look at all the ways you can protect your peace, set up smart filters, use blacklists, and connect databases to automatically detect spam, and effectively locking you off will not only save your nerves, but also protect you from the potential financial fraud that often masquerades as regular calls.
Use of the built-in "Security" application
The main protection tool in Xiaomi smartphones is a pre-installed system application, which is called “Security”, and this is where the main levers of incoming traffic are concentrated. To get started, open the application and find the Antispam (or Lock) section, which is usually located at the bottom of the screen or in the menu of additional tools.
Within this section, you will have a few key settings that you need to activate for maximum protection, especially the Lock Rules, where you can adjust your response to hidden numbers or calls with code other than your region, and the smart filter can analyze behavioral factors and mark suspicious contacts on its own.
- 🛡️ Activate the Block Hidden Numbers to cut off those who hide their own ID.
- 📞 Enable the “Block First Call” option if you are concerned about robot answering machines.
- 🌍 Set up a geo-filter to block calls from other countries if you don't wait for calls from abroad.
Remember to update spam databases periodically if the app offers this option, which will allow the system to recognize new fraud numbers that are constantly changing, and this section often provides access to the Blacklist, where you can manually add specific contacts.
⚠️ Note: When you enable hidden number locking, you may miss an important call from a doctor or courier using corporate PBX.

Blacklisting and manual locking
If you're concerned about a particular subscriber, the most effective method is to manually blacklist their number, which completely prevents that contact from reaching you or sending messages, and this can be done in a number of ways, depending on your current situation and the version of the MIUI shell.
The fastest way is to open a call log, find the intruder's number and click on it (or the "i" icon in the circle). In the context menu that opens, select Block or Blacklist, and then all attempts to communicate from this subscriber will be interrupted at the system level, and the caller will hear beeps or a message about employment, depending on the operator's settings.
To get a deeper setup, go to the phone menu, click three dots in the corner of the screen, and select Settings → Locked numbers. Here you will see a complete list of all locked contacts and be able to manage them centrally. There is also a mask lock feature available, which allows you to cut out entire groups of numbers starting with certain numbers.
- 📱 Add contact directly from the phone book via the card editing menu.
- 🚫 Use the story. SMS to block the spam sender.
- ⌨️ Enter numbers manually in lock settings if you have a list of "pests».
It is important to understand that blocked subscribers can still leave voice messages if you have the appropriate operator function enabled. Therefore, it is also recommended to check the settings of the answering machine. Manual locking is a reliable but time-consuming method if spammers use a pool of hundreds of different numbers.
Automatic Filtering and Databases
Modern Xiaomi smartphones can detect spam automatically by checking the incoming number with huge cloud databases. This feature often works in conjunction with services like Google or its own MIUI databases. To activate the definition of unknown numbers, go to the phone settings and find the item “Detect numberfinder” or “Identification of calling subscriber”.
When you have a call enabled, it can show not just a number, but a note that says "Advertising," "Delivery," or "Probable Spam," and it analyzes other users' complaints, so if you have a number that's been complained about, it's labeled dangerous, and you can set the phone up so that those calls are reset automatically without even vibrating.
Settings → Applications → Phone → Settings → Blocking → Blacklist → Settings → Update the database
Sometimes embedded databases may not be relevant to your region, and it makes sense to consider installing specialized identifiers that have more recent data on local fraudsters. However, the built-in HyperOS tools usually do the basics well without requiring any extra software.
How do spam number databases work?
The database is formed collectively, and when users label a number as "spam" or "fraud," that signal is sent to the server, and if the number of complaints exceeds the threshold, the number is entered into a common list. When you call in, your smartphone sends a request to the server and receives the number status.> Do Not Disturb and Quiet Hours For situations where you need complete silence but are afraid to miss a really important call, Do Not Disturb mode is ideal. Unlike full lockdown, this mode allows you to create exceptions. You can configure it through the Quick Access Panel (swipe from top to bottom) or in the Settings menu. → Sound and vibration. Inside the Do Not Disturb settings, find the Allow Calls section, where you can choose who can reach you, and the best anti-spam setting is to select the Contacts Only option». In this case, any number that is not in your phone book will not cause an audible signal and vibration, but will simply be displayed in the missed log. Also extremely useful is the function "Repeat calls." If the same number rings a second time in 15 minutes, the phone will miss this call. The logic is simple: spammers and robots usually call once and go on, and in the case of real emergencies, people call back. This smart exception saves from missing critical messages. The Recommended value of notifications turns off the sounds of all applications Only the second caller can turn off the phone effects on the Migan mode. For example, you can set up an automatic Do Not Disturb switch on from 23:00 to 7:00. This will save you from the late-night advertising calls that sometimes occur due to the time zone difference in call centers. Third-party spam protection applications If standard Xiaomi tools are not enough for you, the market offers a lot of third-party solutions. The leaders in this niche are applications like Kaspersky Who Calls, Yandex (with Alice), Truecaller or NumBuster. They work on a crowd-sourcing principle, collecting a database of numbers from millions of users around the world. Installing, the market requires a wide range of access to the application, including access to the actual access to the database. After installation and setup, the application will intercept incoming call management and mark spam with bright red plaques. 📲 Truecaller is a global database that defines international spam. 🇷🇺 Yandex is the best base for numbers of the Russian Federation, integrated into the system. 🔒 Kaspersky – focus on security and protection from fraudsters. ⚠️ Note: Installing third-party number detectors may conflict with the built-in number determinant MIUI. It is recommended to disable the native “Determine Numbers” function to avoid double call processing.It is worth considering that some of these applications may be paid or have intrusive advertising in the free version. In addition, by transferring your contacts to third-party servers, you are sacrificing some privacy for convenience. The fight against spam is most effective in a comprehensive manner, so you can not ignore the capabilities of your mobile operator, Tele2) They offer their own services to protect against unwanted calls, and often these services are paid, but their effectiveness is high, because filtering occurs at the network level before the call reaches your smartphone. For example, the service "Antispam" from various operators can not only block calls, but also send SMS-Notification of who called you if the number was recognized as advertising, you can connect such services through the operator's mobile application, in your personal account on the site or using the help of the service. USSD-The advantage of network locking is that it does not consume the battery of your Xiaomi and does not require the installation of additional applications. The phone won't even vibrate when the call comes in, but carrier databases can update more slowly than specialized applications. 💡The combination of Xiaomi’s built-in filter, Do Not Disturb mode and network protection from the operator gives the maximum result in the fight against spam. Check the plan: sometimes anti-spam services are already included in the package or are available for free if certain conditions are met. Operators can also block calls from specific numbers on your customer support request if standard methods don't work (FAQ) Can you block the entire stream of advertising calls 100%? 100% blocking is not guaranteed, as spammers constantly change numbers and use Caller replacement technologies. ID. However, a combination of methods (blacklist, Do Not Disturb mode, and number detector) allows you to weed out about 95-98% of unwanted calls. Will the blocked subscriber see that I blocked it? Direct lock notification will not receive. When calling, he will hear long horns (as if you do not pick up the phone) or short horns of employment. In some cases, if the operator provides Voicemail service, the call can be redirected there. Does the locking of numbers affect the speed of the Xiaomi phone? The use of built-in lock functions has little impact on performance. However, when you call it will hear long horns (as if you do not pick up the battery), but the additional battery charge, especially if the phone calls, the doctor can make an additional memory from the phone. Check the blocked call log regularly in the Security or Phone app, which stores all missed calls that have been filtered by the system, and you can see the number and time of the call, and if necessary, unlock the contact. Do these methods work on older Xiaomi models with Android 9-10? Yes, the basic principles of blacklisting and Do Not Disturb mode are the same for all versions of MIUI and Android. The interface may differ slightly visually, but the functionality remains available on most devices released in the last 5-6 years.
