How to see locked numbers on the phone Xiaomi Redmi 7: all ways

You blocked an unwanted number on Xiaomi Redmi 7, but now you can't remember who it was, or you want to check if an important contact was blacklisted? In this article, you'll find all the relevant ways to view locked numbers, from standard MIUI features to hidden system features, we'll look at not only how to find the list, but also how to manage it: unlock numbers, export data or restore deleted records.

The thing about Redmi 7 (codenamed onc) is that its MIUI firmware can vary by region and version, so some menu items may be called differently — we've taken that into account and provided alternative paths. If your phone runs MIUI 10-14, the instructions below will fit with minimal adjustments.

Important: Xiaomi’s number locking works at the system level, not at the system level SIM-This means that the list of blocked contacts is not synchronized with other devices and is not saved when the phone is reset to factory settings. If you recently updated your firmware or made a hard cut, the lock list could be deleted without the possibility of recovery.

1. Standard method: through phone settings

The easiest method is to use the built-in MIUI tools, which works on all versions of the firmware and doesn't require any additional applications.

1. Open the Phone app (the tube icon on the home screen).
2. Click on the three dots in the upper right corner (menu) and select Settings.
3. Go to the section "Block numbers" (or "Black list" in older versions of MIUI).

If you have MIUI 12+ installed, the path may be slightly different.

Phone → Three points → Settings → Blocking and spam → Blacklist

In this section you can:

• 📞 Unlock the number – swipe the entry to the left or click on the basket icon.
• ➕ Add a new number manually or from a call log.
• 📤 Export the list to the file (not available in all versions) MIUI).
• 🔍 Search by number – if the list is large, use the search bar at the top.

💡

If the blacklist does not show all numbers, check the sync settings in your Mi Account account, and some of the records may be stored in the cloud, but not uploaded to the device.

2. Viewing through the call log (hidden calls)

Locked numbers are not displayed in the main call log, but they can be found through the hidden call filter, a method that is useful if you want to see if any of the blocked contacts have tried to reach you:

1. Open the Phone app and go to the Journal tab.
2. Click on the three dots in the top right corner and select Hidden Calls (or Filter → Blocked).
3. The system will show all missed calls from the numbers from the blacklist.

Please note that this section only displays incoming calls, not SMS or other interactions. If you need to see blocked messages, use the method in the next section.

3. Check blocked SMS and messages

On Xiaomi Redmi 7, the number lock applies not only to calls, but also to SMS.

1. Open the Messages app (an envelope icon).
2. Click on the three dots in the top right corner and select Settings.
3. Go to Blocking and Spam (or Blacklist)
4. Here you will see the tab Blocked posts with history.

Unlike calls, blocked SMS is stored for a limited time (usually 30 days), and then it is automatically deleted. If you need to save this data, export it manually:

• 📄 Click on the message and hold your finger to highlight.
• 📋 Select Export or Save as Text.
• 📎 Save the file in Downloads or send it to your mail.

4.Use of the application "Security" (Security)

MIUI has a separate security app (com.miui.securitycenter) that duplicates some locking features, and you can also use it to manage the blacklist:

1. Open the Security app (shield icon).
2. Go to the Tools (or Optimization) tab.
3. Select Number Lock or Antispam.
4. There will be a duplicate of the blacklist from the phone app.

The advantage of this method is that you can configure additional lock parameters here:

• 📵 Blocking Unknown Numbers – automatically adds to the blacklist all numbers not saved in contacts.
• 🤖 Spam filtering – uses Xiaomi’s database to block known spammers.
• 🔔 Block Notifications – Turn on to see how many calls have been blocked.

Set up filtering for unknown numbers |Enable blocking notifications |Update spammer database |Sync check with Mi Account

-->

5. View through the file system (for experienced users)

If standard methods don’t work (for example, after resetting), you can try to find a list of locked numbers in system files, which requires root rights or access to ADB, but gives you the most complete information.

The list of blockages is stored in the database:

/data/data/com.android.providers.contacts/databases/contacts2.db

To extract data:

1. Connect your phone to your PC and enable USB Debugging (Settings → About Phone → MIUI version – press 7 times, then go back to Additional → For Developers).
2. Use ADB to copy the file: adb pull /data/data/com.android.providers.contacts/databases/contacts2.db
3. Open the file with SQLite Browser and find the table blocked_numbers.

⚠️ Warning: Do not edit this file manually without a backup! Errors can result in the loss of all contacts on your phone.If you are not sure about your actions, use the standard methods from the previous sections.

6 Recovery of the deleted blacklist

If you accidentally cleared the lock list or reset your phone, you can only restore it if you meet two conditions:

1. You have synced with Mi Account.

To recover the data:

1. Open the Settings. → Accounts. → Mi Account.
2. Make sure that the synchronization of contacts and settings is enabled.
3. Go to Phone → Settings → Lock numbers and wait for automatic synchronization (can take up to 5 minutes).

If synchronization doesn’t work, try manual recovery:

• 📱 Install the “Mi Mover” app from Google Play.
• 🔄 Select Data Recovery → Blacklist.
• 📂 Specify the path to the backup (if it is saved in the cloud or on PC).

💡

Without backup or sync with Mi Account, you can't restore the deleted blacklist.

7. Alternative applications for lock management

If standard MIUI tools don’t suit you, you can use third-party apps, which offer advanced features like cloud backup, spam analysis, and even keyword blocking in SMS.

Top.-3 Applications for Xiaomi Redmi 7:
