Owners of Xiaomi, Redmi and Poco smartphones regularly face intrusive spam and calls from scammers. Standard tools of the MIUI shell or the new HyperOS allow you to effectively filter unwanted calls without installing third-party software. The system functionality allows you not only to ignore the subscriber, but also to hide the fact of the call, which is especially important for maintaining peace of mind.
The lock procedure may vary depending on the version of the operating system and the region for which the device is released. In some firmware, the menu is hidden deep in the security settings, in others it is available directly from the call log. It is critical to consider that on devices with global firmware (Global ROM) some functions may be called differently than on the Chinese versions (CN ROM).
Below we will discuss in detail all the current ways to add to the blacklist on shaomi, using the built-in tools of the system.
The fastest way to restrict access to an unwanted subscriber is to use a standard call log. This method is universal for most shell versions and does not require a deep dive into the settings menu. You will need to find a specific number in the history of incoming or outgoing. Click on the call icon to open a list of all contacts you have interacted with. Find the desired number or name you want to block. Prolonged pressing (tap and hold) on the line with the number will cause a context menu where you should select "Block" or "Add to the call icon to the list of information in the right, or "if you open the a black list or a long list of the arrowrowrow from the menu." Going to the contact card also allows you to find the lock button, often located at the bottom of the screen or in the three-point menu. 📞 Click and hold the number in the call log for quick access to the menu. ℹ️ Use a contact card if the direct menu is not displayed on the screen. 🚫 Confirm the action to the number went to the status of blocked. 🔄 To unlock, repeat the action and select Unlock. Once you do this, the subscriber will no longer be able to reach you, receiving a busy or reset signal, depending on the operator's settings. 📊 How do you block spam most often?Through call log Through security settingsWith third-party apps
The central element of access control in Xiaomi smartphones is the system application Security. This is where the most flexible filtering tools are concentrated, allowing you to manage not only individual numbers, but also entire categories of calls. Launch the Security app with a green shield icon on your desktop. If this section is not visible on the app's home screen, click on the settings gear in the upper right corner or scroll down the tool list. Inside the Antispam section, you'll see two main switches: Call Lock and Lock SMS». Activate them by moving the sliders to the "On" position». Here is the button "Black List", the transition to which opens a full list of blocked contacts and allows you to add new ones manually. ⚠️ Note: In some versions MIUI The antispam menu may be hidden. If you don't find it, go to Settings → Annexes → All applications → Security → Anti-spam or search by phone settings, manually adding a number through the Add button (often looks like a plus), the system will suggest selecting a number from contacts, entering it manually or taking it from the call log. This is convenient if the caller has hidden the number or you want to block the range. ☑️ Checking lock settings Open Security Application Active Antispam Section Included call blocking Checked blacklist for numbers: 0 / 4
Sometimes a lock is required for a contact that is already saved in your phone book but has begun to behave inappropriately, in which case it is most logical to act directly from the card of the saved number, so as not to search for it in the shared log. Open the Contacts app or go to Contacts inside the call. Find the entries you want in the alphabetical list. When you open a detailed subscriber card, look at the bottom of the screen or the three-dot menu in the corner. The action menu usually has a "Block" item. Once clicked, the system will request confirmation, and there may be a blacklist option available, which duplicates the lock function, but with an emphasis on filtering. 👤 Open the saved contact card in the phone book. ⚙️ Find the action menu (three dots or button at the bottom). 🛑 Select the option of blocking or adding to the emergency. ✅ Make sure the contact status is changed to blocked, which is especially useful because you can immediately see who you are restricting access to, and you can quickly cancel the action if the lock was wrong.
Advanced settings and filters MIUISystem system MIUI And HyperOS offers advanced lock scenarios that go beyond a simple blacklist: You can set up automatic screening of calls from hidden numbers, international codes or advertising agencies. Go back to the Security app and select Antispam. Click on the gear icon (Settings) in the upper right corner, and it opens the Lock Rules menu, and this is where the most powerful tools are hidden, and activate the Lock Hidden Numbers switch if you're concerned about anonymous calls. The option “Block numbers from other regions” is also available, which is useful for protection against international spam. In the “Periodic lock” section, you can set the time when calls will be ignored (Do not disturb mode with increased filtering). Filtering parameter Action Description Recommendation Hidden numbers Block calls without a determinant Include if there are no expectations of anonymous calls International Cuts off codes of other countries Include if there are no foreign contacts Ads Blocks tagged as spam Recommended to keep active Not from contacts White list (only contacts) Only for maximum isolation The use of these filters significantly reduces the load on the psyche, cutting off up to 90% of automated debris even before the phone rings. What happens to blocked SMS?Blocked messages are not deleted, but moved to a special folder "Spam" within the application Anti-only check the contents from them in the 30 days they can be automatically deleted.
Features of work in HyperOS and new versions MIUIWith the release of the HyperOS shell and updated versions MIUI 14, the lock management interface has undergone changes. Google has tightened its security policy for Android, which also affected the ability to filter calls on Xiaomi smartphones. In newer versions, the system app Security can redirect users to Google’s standard determinant or require additional permissions to operate the filter. The interface has become more minimalistic, and some deep settings have moved to Settings. → Protection of confidentiality → In addition, global firmware versions can be reduced in terms of antispam functionality compared to Chinese counterparts, in which cases the system relies on Google’s database, which does not always effectively recognize local spam. Users may need to manually update spammer databases or use alternative methods. ⚠️ Warning: After upgrading to HyperOS, the path to settings may change to Settings → Annexes → System application settings → Phone. → Block. Look for sections related to Spam Protection. If standard methods stopped working after the update, try clearing the Security and Phone app data through the application management menu, then re-activate the filters. 💡Use Google’s Number Define feature or Yandex integrated into the call. They often flag spam calls in red before you even respond, allowing them to be blacklisted preventively.
Sometimes users are faced with a situation where the subscriber added to the blacklist continues to call or arrive SMS. This may be due to the peculiarities of the operator or failures in the system. The first reason is often the use of the subscriber services of masking the number or calls through Internet messengers (Viber, WhatsApp, Telegram), which do not pass through the standard telephone network and are not filtered by the system blacklist. For messengers, the lock must be configured inside each application separately. The second reason may be a crowded memory of the “Spam” section. If the storage of messages is overflowing, new systems may not be blocked. 📱 Check if you are not called via messengers (WhatsApp, Telegram). 💾 Clear the memory of the blocked SMS in the appendix Security. 🔄 Remove the number from the emergency and add it again, restarting the phone. 📞 Contact your carrier to connect a paid network-level lock service. In extreme cases, when spam comes from changing numbers, only the White List mode, which allows calls only from saved contacts, will help. 💡Xiaomi’s blacklist is effective against regular calls and SMS, but powerless before calls through Internet applications - they need separate settings inside messengers.
Frequently Asked Questions (FAQ)
Does the user know that he is blacklisted on Xiaomi?
The system does not send a direct notification. The subscriber will hear short beeps, like when the lines are occupied, or a message of unavailability, depending on your operator's settings and the version of MIUI. It will look like a regular call reset.
Can I add a prefix or a group of numbers?
In standard MIUI settings, mass-addition by mask (for example, all numbers starting at +7999...) is usually not available, but you can use third-party identifiers that have spam databases and block them automatically.
Where are the blocked SMS messages stored?
They don't get deleted, they go to the Spam or Blocked folder, and you can find them in the Messages app (three-point menu → Blocked) or through the Security app → Antispam → History.
Does the blacklist work if the phone is turned off?
No, because call processing is on the device. If the phone is off, the call simply won't arrive. However, if your carrier has a network-level blacklist service, it will work regardless of the state of your smartphone.
