Xiaomi Redmi 7A, based on MIUI, offers built-in tools to block unwanted calls, but it’s not always obvious where to look for a list of already blocked contacts. If you accidentally blocked an important number or want to check who was blacklisted, this article will help you understand. Unlike the newer Redmi models, the Redmi 7A lock management interface is hidden deeper in the settings, and some features require additional manipulation.
We’ll look at all the available ways, from standard MIUI settings to hidden system features that work even without root rights. We’ll pay special attention to the nuances of the Redmi 7A firmware, since on this device the path to the list of locked numbers may be different from other Xiaomi models. If you tried to find this section and didn’t find it, don’t be surprised: in some versions of MIUI 10/11 it is hidden under non-obvious menu items.
Method 1: Using the standard phone settings
The most direct way is to use the built-in MIUI tools. On Redmi 7A, the algorithm is different from more modern devices, so follow the instructions carefully:
- Open the Phone app (the tube icon on the home screen).
- Click on the three dots in the upper right corner (menu) and select Settings.
- Go to the section "Block numbers" (some firmware may be called "Black list").
- Here you will see a full list of blocked contacts with the possibility of unlocking.
If you don't have Number Lock on the menu, your version of MIUI uses an alternative path.
- 📱 Go to Settings. → Annexes → Application management.
- 🔍 In the search bar, enter “Phone” and select the system application.
- 🔒 In the Permissions section, find the Number Lock – there may be a link to the list.
💡
If the lock section disappeared after the MIUI update, try resetting the Phone app settings through Settings → Apps → Phone → Storage → Reset. This will return the standard menu.
Method 2: Use of the Security App
On Redmi 7A, the Security app (shield icon) duplicates some of the locking functions, which works even if the standard path through the Phone doesn't work:
- Launch the Security app.
- Go to the Block tab (or Privacy Protection in older versions).
- Select Call Lock – here will be a list of all the blocked numbers.
You can also set up automatic blocking of spam calls through Xiaomi’s database in this section.
- 📵 Numbers blocked through Security may not appear in the Phone app list, and vice versa.
- 🔄 Synchronization between these two locking systems doesn’t always work – check both sources.
Method 3: View through the call log
If a number has been blocked recently, it can be found in the call log - even if it doesn't appear in the main lists - and this method is suitable for checking the latest actions:
- Open the phone» → «Journal».
- Click on the three dots in the top right corner and select Settings.
- Activate the option to Show blocked (if you have one in your version of MIUI).
- Blocked rooms will be illuminated in gray or marked with a special icon.
On Redmi 7A, this is unstable, depending on the firmware version. If you don't have the option to show locked, try an alternative path:
- 🔎 In the call log, type in the search symbol * - this can display hidden entries.
- 📋 Check the Spam tab (if any) – sometimes blocked numbers get there.

Method 4: Through the file system (for advanced users)
If standard methods don't work, you can try to find a list of locked numbers in system files. On Redmi 7A, without root permissions, this method will give you limited access, but sometimes helps to recover lost data.
You will need a file manager with access to hidden folders (such as MiXplorer or Solid Explorer):
- Open the file manager and go to /data/data/com.android.providers.contacts/databases/contacts2.db
- Copy the contacts2.db file to your computer and open it via SQLite Browser.
- In the table blocked_numbers All blocked numbers will be stored.
Important nuances:
- 🔐 Without root rights, you won’t be able to read this file directly – only through a backup.
- 📱 Some of the ways may be different: try it. /data/user_de/0/com.android.providers.contacts/...
- ⚠️ Do not edit the file manually – this can cause the contact database to crash.
Backup Contacts Through Settings → Google → Backup
Install a file manager with root support (if you have permissions)
Download SQLite Browser to your computer
Do not edit files directly on your phone-->
Method 5: Third-Party Applications for Lock Management
If embedded tools MIUI They don't like it, you can use third-party utilities, and they not only show locked numbers, but they also add advanced filtering functions. 7A:
| Annex | Functions | Features |
|---|---|---|
| Truecaller | Blocked display, spam identification, cloud database of numbers | Registration may be in conflict with system locking |
| Blacklist | Local blacklist, lock log, backup | It doesn’t depend on MIUI, it works offline. |
| Calls Blacklist | Flexible locking rules (in terms of time, contacts, regular expressions) | The paid version removes the ads |
When installing third-party applications, consider:
- 🔄 They create a separate block list that is not related to the system.
- 📴 Some utilities (such as Truecaller) can unlock numbers added through MIUI.
- 🛡️ Before installing, check permissions: the application must request access to the Call Log and Contacts.
💡
Third-party applications are useful if you need to keep a lock history or advanced filters, but they don’t replace MIUI system locks — both mechanisms work in parallel.
Frequent problems and their solutions
On Redmi 7A, users often face the typical difficulties of working with locked numbers, and here are the most common scenarios and ways to solve them:
⚠️ Note: If after the update MIUI All the locked numbers are missing, and this is due to the reset of the Phone application database, and you can only restore them from a backup. contacts2.db (see method 4).
Problem 1: Not all numbers are displayed in the lock list. Solution: Check both the Phone app and the Security app. They're using different databases.
Problem 2: The locked number still passes. Solution: Make sure Settings → Apps → Phone → Permissions enable Call Blocking. Also check if the number is added to the exceptions in the Security app.
Problem 3: You can't unlock the number - the button is inactive. Solution: Reboot your phone or clear the phone app cache through Settings → Apps → Phone → Storage → Clear the cache.
💡
If you frequently block and unlock numbers, create a shortcut for quick access: add the “Number Lock” widget to the home screen via a long tap → “Widgets” → “Phone” → “Blocking”.
