How to remove the blacklist on Xiaomi phone: the complete guide

The blacklist on Xiaomi smartphones is a useful feature for blocking unwanted contacts, but sometimes it works too aggressively. You may accidentally add an important number to the lock or find that the phone itself blacklists the desired contacts. In this article, we will examine all the ways to disable the blacklist on Redmi, POCO and Mi devices – from standard settings to hidden MIUI features.

Xiaomi’s blacklist can be duplicated in multiple places: in the Phone app, in security settings, and even in some firmware versions, integrated into Google services.We’ll show you how to check all possible sources of lock to ensure that any number is unlocked.Instructions are relevant for MIUI 12-14 and Android 11-14, including the latest updates from 2026.

1. Standard method: via the "Phone" application

The most obvious and quickest method is to use a built-in call app, which works on 90% of Xiaomi devices without having to dig into system settings.

Open the Phone app (the phone icon) and follow the following steps:

• 📱 Find three dots (menu) in the upper right corner and click on them.
• 🔍 In the drop-down list, select "Black List" (or "Blocking Numbers")
• ❌ Next to each locked number will be a basket icon or cross – click on it
• ✅ Confirm the removal of contact from the blacklist

If your phone's menu looks different, try an alternative route: Phone → Contacts → Menu (three dots) → Settings → Lock numbers. On some POCO models, the blacklist may be called "Blocked List."

💡

On double-phone phones. SIM-Check the blacklist separately for each SIM card – locks can be duplicated!

2. Checking the MIUI security settings

MIUI has a separate security section where it can also be blacklisted, especially for devices with Xiaomi.eu firmware or global versions where features are duplicated.

Go to: Settings → Applications → Application Management → Phone → Permissions → Number Locking

Or an alternative way:

Settings → PaSSWORD & SECURITY → Number locking

• 🔒 Check the list of blocked numbers in this section
• 📋 Compare it to what you saw in the phone app – sometimes the numbers are duplicated.
• 🗑️ Delete unnecessary entries by clicking on the basket icon

On some models (Redmi Note 10 Pro, POCO X3 Pro) in this section you can see the history of blocking in the last 30 days. If the number was blocked automatically (for example, as spam), here will be the reason.

3.Resetting the blacklist through the engineering menu

If standard methods didn't work, it might be a system-level lock, in which case an engineering menu (not to be confused with developer mode!) will help. This is a precautionary approach, but it's effective for deep locks.

Enter the combination in the "Phone" app: ##4636###

A test menu will open where you need:

1. Select the item "Telephone Information"
2. Scroll down to the "Call Lock" section.
3. Click "Clear Blacklist" (or "Clear Blacklist")
4. Confirm the action

Important: After resetting through the engineering menu, all locks will be removed without recovery, including those installed by system applications.

4.Delete the blacklist through ADB (for advanced)

If you are familiar with ADB (Android Debug Bridge), this method will give you full control over locks, and it will come in handy when the number is locked at the system level and does not appear in the standard settings.

Connect your phone to a computer with installed ADB-driver and perform:

adb shell


su




pm clear com.android.server.telecom




pm clear com.miui.guardprovider




pm clear com.android.contacts

These commands reset the cache of the system applications that are responsible for blocking.

• 🔄 Reboot the phone.
• 📱 Check the blacklist in the phone app – it should be empty
• 🔧 If necessary, restore important contacts from backup

Install ADB drivers on PC|

Enable debugging over USB in the developer settings |

Make a backup of contacts |

Connect your phone to the original cable-->

⚠️ Attention: Use ADB It requires super-user rights on some firmware. Without root, only cache clearing commands are available, which may not work on heavily modified versions. MIUI.

5. Verify sync with Google and Mi Account

Many users are unaware that Xiaomi can sync the blacklist with cloud services. If you previously blocked numbers on another device with the same Mi Account or Google account, the locks could be transferred automatically.

To check and disable cloud sync:

After the synchronization is disabled:

1. Remove all locks manually (see Section 1)
2. Reboot the phone.
3. Turn the sync back on if you need it.

Resetting the settings of the Phone application (last resort)

If all previous methods failed, the radical solution is to reset the phone app to factory settings, which will remove all user settings, including the blacklist, but save the contacts themselves.

Follow the following steps:

1. Open Settings → Applications → Application Management
2. Find the Phone app (or Contacts) and select it
3. Press "Storage" (or "Memory")
4. Select "Erase Data" and "Clear Cache"
5. Confirm the action.

⚠️ Warning: All call settings, including call history, favorite contacts and custom tunes, can not be backed up - these data are stored only locally.

Some models (Redmi K50, POCO F4) will need to reset the permissions for the Phone application, including access to contacts and microphone, after resetting.

💡

Before resetting the Phone app, export important contacts to the VCF file via the Contact Menu – this is the only way to save them.

Additional advice and frequent problems

Even after being removed from the blacklist, some numbers may remain blocked.

• 📵 If they don't come SMS: Check the lock in Settings → Annexes → Communications → Spam protection
• 🔕 If calls are reset immediately: turn off "Do Not Disturb" in Settings → Notifications → Don't disturb mode"
• 🤖 If Google Assistant is Blocking: Open Google Settings → Account management → People and Sharing → Contacts → Blocked
• 📡 If the problem after the update: reset the network settings in Settings → SIM-maps and mobile networks → Resetting network settings

On devices with MIUI 14, a smart lock feature has been introduced, which automatically blacklists numbers marked as spam by the community to disable it:

1. Go to Settings → Applications → Application Management → Security
2. Select "Spam Protection"
3. Turn off the option "Block spam calls"
4. Remove all numbers from the list of "Public Complaints"

If you use third-party apps to block calls (like Truecaller or Call Blocker), check their settings separately - they can duplicate the system blacklist.
