The Xiaomi Redmi 7A remains a popular budget smartphone even years after its release, but its owners often face the need to clean the call log. The reasons range from the desire to hide personal information to the banal filling of memory with system logs. Unlike modern flagships, the MIUI on the Redmi 7A has its own nuances - for example, the lack of a mass removal feature in some versions of the firmware or hidden restrictions on cleaning through standard menus.
In this article, we will discuss all the current ways to delete your call history, from basic (via the Phone app) to advanced (using ADB and engineering menus). Particular attention will be paid to the problems that Redmi 7A users face on MIUI 10/11/12, where the cleaning interface may differ, and you will learn how to bypass the deletion lock for individual contacts and what to do if the log “hangs” after cleaning.
Why the Redmi 7A call log isn't cleaned in standard ways
Many users complain that after clicking "Clear log" in the Phone app, the call history remains in place, the reason lies in the features of MIUI for budget devices:
- 🔄 Data caching: The system can temporarily store a copy of the log in cache, which is why calls are returned after a reboot».
- 📱 Firmware restrictions: On Redmi 7A s MIUI 10 Global Stable Mass Deletion Function Is Incorrect Due to a Database Error call_log.db.
- 🔒 Sync with Mi Account: If sync is enabled, the log can be recovered from the cloud even after local cleaning.
- 🛠️ Damaged System Files: After failed updates or resets, log files (/data/data/com.android.providers.contacts/databases) They may be “reading only».
Another common problem is the inability to delete calls from a particular contact, which is because MIUI blocks editing of records associated with synchronized accounts (such as Google or Mi Cloud), in which case only a full log reset or disabling sync will help.
⚠️ Note: If you are using Redmi 7A With custom firmware (such as LineageOS or Pixel Experience), standard cleaning methods may not work, in which case you will need to manually delete the calllog.db file through the Root Explorer.
Method 1: Standard cleaning through the application "Phone"
The simplest method that works on most MIUI versions for Redmi 7A is suitable for deleting all records or selective calls:
- Open the Phone app** (the phone icon on the home screen).
- Go to the Journal tab** (usually located to the right of Contacts).
- Press three points (⋮) in the upper right corner and select “Log Settings».
- Slip on the “Clear Journal” option** and confirm the action.
If the “Clear Journal” option is missing (relevant to MIUI 10), try the alternative path:
- In the call log, click and hold any call until the tick appears.
- Select all the entries (or required) and click on the basket icon in the top panel.
Some firmware may have a "Journal is empty" notification after cleaning, but when the device is restarted, the calls will return, indicating that the log database has been damaged, in which case you move to method 3 or 4.

Method 2: Remove through System Settings
If the Phone application does not respond to commands, try to clear the log through system settings, which will work even if the MIUI interface is modified:
- Open "Settings»** (⚙️ mainscreen).
⚠️ Warning: This method will delete all call history, including saved numbers for quick dialing, and the settings of the Phone application may also reset (for example, the number detector will turn off).
If the “Clear Data” button is inactive, it means:
- 🔐 You do not have administrator rights (relevant to corporate devices).
- 📴 The Phone application is protected by the system (for example, on firmware with Work Profile).
- 🔄 There was an error in the section mounting /data (help reboot).

Method 3: Use of an engineering menu (for power users)
If standard methods don’t work, you can use Xiaomi’s engineering menu, which requires caution, as incorrect actions can cause malfunctions in the phone.
Instructions:
- Open the Phone app** and enter the combination: ##4636###.
- Scroll down to the Call Log section and click on Clear Data.
On the Redmi 7A with MIUI 12 and later, the engineering menu can be blocked.
- 🔧 Use the alternative code: ##284## (a batch test, but sometimes opens up logs).
- 📱 Install the app «MTK Engineering Mode (Available on Play Market) if your Redmi 7A on a MediaTek processor.
| Engineering menu code | Function | Works for MIUI. |
|---|---|---|
| ##4636## | Phone information and log reset | 10, 11, 12 (partially) |
| ##284## | Packet data test (can open logs) | 10, 11 |
| ##6484## | MTK Test (MediaTek processors only) | 10 (11/12 requires rights) |
| ##64663## | HW test (can reset system logs) | 10, 11 (not on all firmware) |
💡
If the engineering menu doesn't open, try entering codes through the standard Calls app, rather than through the launcher keyboard. On some firmware, this solves the problem.
Method 4: Cleaning through ADB (for advanced users)
If none of the previous methods worked, it is left to manually clean through ADB. This method requires connecting the smartphone to the computer and basic command line knowledge.
Step-by-step:
- Download and install platform-tools (part of the Android SDK) on your PC.
- Turn it on on Redmi. 7A «Debugging by USB»** (Settings → The phone. → Version. MIUI (press 7 times) → Settings → Additionally. → For developers → Debugging by USB).
If the team doesn’t work, try an alternative:
adb shell pm clear com.android.contacts
adb shell pm clear com.android.dialer⚠️ Note: pm clear commands will reset all contact and phone app data, including selected numbers and settings. Once executed, you may need to re-synchronize your contacts with Google or Mi Cloud.
If ADB issues a “Permission denied” error, it means:
- 📴 You have an outdated version of platform-tools (update via the SDK Manager).
💡
ADB is the most reliable way to clean the log, but it requires preparation. If the commands don't work, check if the antivirus or firewall on the PC is blocking them.
Method 5: Recovery Mode Reset (extreme case)
If the call log is stuck and not cleared by any method, it is hard to reset through Recovery, which will remove all data from the device, so use it only as a last resort.
Instructions:
- Turn off Redmi 7A.
- Press the Nutrition + Volume Up buttons at the same time and hold for 10-15 seconds until the Mi logo appears.
This method is guaranteed to delete the call log, but also:
- 📡 Could lead to loss IMEI (rarely, but perhaps on unofficial firmware).
⚠️ Note: Some versions of Redmi 7A s MIUI 12 Recovery menu can be blocked.In this case, you will need to unlock the bootloader through the official Xiaomi website.

Additional tips: how to prevent automatic journal recovery
Even after a successful cleanup, the call log can recover due to:
- ☁️ Synchronization with Mi Cloud or Google.
- 🔄 Automatic backup (included by default in the MIUI).
- 📱 Backup applications (e.g. Mi Mover or Titanium Backup).
To avoid this:
- Open “Settings” → “Accounts and Synchronization”.
It is also recommended that:
- 🛡️ Install a third-party log-blocking app (such as Call Logs Backup & Restore) that allows you to selectively manage your logs.
- 🔍 Regularly check application permissions in Settings → Annexes → Permissions to prevent access to the log of extraneous programs.
