How to remove a number from the blacklist of Xiaomi

The situation of missing an important call due to accidental locking is familiar to many smartphone owners. The built-in MIUI algorithms and the new HyperOS shell often take a user’s actions proactively, adding unwanted contacts to the ignore lists, sometimes automatically when trying to protect against spam, and sometimes due to an error when quickly navigating the menu.

Understanding how to remove a number from Xiaomi’s blacklist is a critical skill to restore normal communication. Call filtering works at a deep level, so simply removing a contact from a phone book won’t unlock it automatically.

In this guide, we will take a look at all the possible ways to unlock subscribers, from standard shell tools to advanced settings through the engineering menu. We will look at the nuances of working with Google contacts and system security applications, which often duplicate each other’s functions, creating confusion.

⚠️ Warning: After unlocking the number, it is recommended to restart the device to reset the cache of the communication module and ensure the passage of incoming calls.

Difference Between Blocking Contact and Blacklisting

Many users mistakenly believe that deleting a contact from a phone book automatically removes all communication restrictions. In fact, a blacklist is a separate software filter that processes incoming calls and SMS before they reach the screen. Deleting an entry from the address book only erases the name and additional data, but does not affect the filtering rules associated with the phone number.

There are two main types of locks on Xiaomi devices: the first type is blocking a particular subscriber who is listed as banned through the Security app or call settings. The second type is global settings, such as Do Not Disturb or locking all unknown numbers. It is important to distinguish these concepts clearly, since the methods of disabling them are radically different.

The MIUI system logic is designed to prioritize antivirus and spam filter settings, so if the number is in a malicious contact database or has been labeled as spam by the user himself, the system will ignore dialing attempts even if the number is saved in Favorites, which is why it is necessary to check the sections responsible for security and filtering.

• 📱 Blocking through the Security app is the most common method managed by local rules.
• 🚫 Global Unknown Lockdown – System settings that hide calls from numbers not in contacts.
• 🔇 Do Not Disturb Mode is a temporary filter that can ignore all calls except select ones.

It's worth noting that in recent firmware versions, the interfaces may be slightly different, but the logic remains the same: communication and security settings are two different security loops. If you don't find a number in one place, be sure to check the other.

Delete the number through the application "Security"

The most effective and frequently used way to manage locks is the regular Security app, which is preinstalled on every Xiaomi device. This is where the basic call and message filtering tools are concentrated. To get started, find a green shield icon on your desktop and launch the app.

In the menu that opens, you need to scroll down to the "Blocklist" section, which in some versions of the shell can be called "Antispam" or have a shield icon with a prohibitive symbol, and inside this section you can keep a complete log of blocked communication attempts and a list of numbers that have been added to the blacklist manually.

Once you go to the Blacklist, you'll see a list of all the locked numbers. To delete a particular subscriber, click and hold your finger on the right line, and then the context menu or the top action bar will appear. Select the Delete option or the basket icon. The system can request confirmation of action, because this is a change in security rules.

It is important to understand that removal from this list immediately removes the ban on incoming calls and SMS-However, if the number is marked as “Advertising” or “Telemarketing” in the general database, it can be blocked automatically again on the next call, unless the corresponding smart filter option is disabled.

⚠️ Note: In some regions, the Security app may have a stripped-down functionality. If you don't find the Lock option, try changing the region in your phone settings to India or Russia».

Set up a lock through a standard call

An alternative way to manage bans is through the standard Phone app, which is convenient because it allows you to quickly check the status of a particular number right in the call history. Open the call app and go to the tab with the history of recent calls or the contact section.

Find the number that is supposedly locked. If the number is locked, a special icon (such as a crossed-out phone or a red circle) may be displayed next to it. Click on the information icon "i" or swipe the number to see what actions are available. The number management menu should have the option "Unlock" or "Remove from the blacklist".

You can also access the general lock settings via the call interface, click on the three dots in the corner of the screen or the menu button and select Settings → Locked Numbers, and here is a full list of ignored contacts that is synchronized with the BSafe app.

If the number doesn’t appear in the blocked list of the call, but the calls don’t go through, the problem may lie in the operator’s settings or in third-party applications such as Truecaller, if they have call management rights, in which case you need to check the application permissions in the Android system settings.

Using Google Contacts to Manage Access

With modern versions of Android and HyperOS shells, contact management is increasingly being moved into the Google ecosystem. If you’re syncing with a Google account, check your settings there. Open the Contacts app (usually with a colored “K” or human silhouette) and find the contact you want on the list.

When you go to the contact card, look at the top of the screen or the option menu (three dots). If the contact is blocked, the Unlock button will be active there. In some cases, the lock is through a hidden menu, which is caused by a long click on the contact name in the shared list.

The thing about Google Contacts is that the changes don't apply instantly to all devices, so if you unlock a number on your phone but it still can't reach you, check if it's worth blocking at the level of your Google Voice account or other related services.

This table helps you quickly navigate where the ban might have been lost, and it is the first item that most often solves the problems, since the MIUI system filter has the highest priority for processing incoming traffic.

Do Not Disturb Mode and Hidden Settings

Often, users will unnoticed activate the Do Not Disturb mode, which blocks all incoming calls except those marked as Favorites, and you can check the status of this mode by swiping the notification curtain down and finding the crescent icon. If it is active, just turn it off.

A more subtle setting is available from the Settings menu → Sound and vibration → Do not disturb. You can set exceptions here. Make sure that the exceptions do not include the "Contacts Only" or "Favorites Only" restriction if you are waiting for a call from an unknown or new number. Also check the schedule: it is possible that the mode will automatically turn on at certain times of the day.

Another hidden feature is blocking Hidden Numbers or Undefined Numbers, which is located in the call settings menu (Phone → Settings → Inbound Lock). If this switch is active, any calls where a subscriber has hidden their ID will be automatically rejected by the system without notice.

For advanced users, there is the ability to manage locks through ADB-commands if the standard interface is not working properly, but it requires a computer connection and debugging. USB. The command to reset the blocker settings usually looks complicated and is not recommended for ordinary users without technical training.

adb shell pm clear com.miui.securitycenter

Executing such a command will reset the security application settings, which can result in the removal of all blacklisted user rules, and use this method only in extreme cases where a software failure does not allow the number to be removed in standard ways.

Problems with the number detector and third-party applications

Xiaomi smartphone owners often install third-party number detectors such as Truecaller, GetContact or Yandex with Alice.These apps have their own databases and lock mechanisms that work independently of the MIUI system settings. If the number is locked in such an application, the system blacklist will be clean, but calls will still not pass.

To solve the problem, you need to open the detector app, find the “Block” or “Blacklist” section in its settings and delete the desired number from there, and check whether the “Block Spam” tick with an aggressive filtering level that can mistakenly mark normal numbers as dangerous is worth checking.

💡

If you use multiple number determinants, make sure their databases don't conflict. It's best to leave only one active application to prevent filtering errors.

Additionally, some apps may request “Call Over” or “SMS Filtering” rights. If you recently installed a new app and then lost calls, check its permissions in the Settings menu → Apps → All Apps → [App Name] → Permissions. Disabling phone rights often solves the problem.

⚠️ Note: Third-party apps may have access to your contacts and calls. Check the list of apps with phone permissions regularly in your privacy settings.

Frequent Questions and Decisions (FAQ)

💡

The rule is, always check the three points of control -- the system application Security, the call settings, and third-party number detectors -- locking in any of these places will shut down communications.

To sum up, managing contacts on Xiaomi requires attention to detail. The system offers layered protection that, if set up incorrectly, can be a barrier to communication. Regularly checking lock lists and understanding the difference between system and third-party filters will help you stay connected in any situation.
