Xiaomi Redmi Note 7 remains a popular device, but over time, its software can accumulate excess data, including phone history. Many users face the need to hide information about calls from prying eyes or simply free up space in the system log. Clearing the call list is not just about deleting records, but also understanding how the MIUI system log works and where this data is stored.
In this article, we will take a closer look at all the available methods for removing call history, from the standard interface to advanced methods through the engineering menu. MIUI has its own specifications, different from pure Android, so it is important to know the right sequence of actions for an effective result.
This procedure can be necessary for various reasons: selling a device, transferring a phone to another user or a simple desire to preserve privacy. It is important to understand that completely removing traces of communication requires care, since some data can be duplicated in cloud services or synchronized with a Google account.
Standard method of cleaning through call log
The most obvious and affordable method is to use the phonebook's built-in functionality. The MIUI Dialer interface allows you to manage your story in a flexible way, providing tools for selective or mass deletion of records. To start, open the standard Phone app and go to the Journal tab.
To delete a specific number, just click on it long enough, and in the context menu that appears, select the option “Delete”. If your goal is to completely clean up, tap the menu icon (three dots or lines) and select “Clear call log” option, the system will request confirmation, since it will be impossible to restore deleted data using standard means.
💡
Before completely cleaning the log, take a screenshot of important numbers or copy them to contacts so as not to lose the necessary information irretrievably.
It's worth noting that logging does not erase a number from the phone book if it's stored there, but that separation allows you to keep your call history clean while keeping your contacts, but if the number was incoming and not saved, it will disappear from the device's memory completely after you do this.
☑️ Checking before cleaning
Using the “Security” application for deep cleaning
The MIUI shell preloads a powerful system-based security application that manages not only antivirus protection but also garbage cleaning. Call log, while it takes up little space, is a category of user data that can be cleaned through this tool, especially if the phone's standard menu is not working properly.
Run the Security app and find the Cleanup section. After scanning, the system will prompt you to delete temporary files. For a deeper cleaning, go to the Garbage Cleanup section and look closely at the categories. Sometimes the call history may be hidden in the app cache section or in the Other category.
⚠️ Attention: Using aggressive cleaning methods through third-party utilities can result in the removal of not only the log, but also important system logs needed for diagnosis.
Also in the Security settings, there's a Privacy feature that allows you to hide certain apps or data. While it doesn't remove calls physically, it makes them unavailable without a password or fingerprint, which is a great alternative to complete removal.
| Cleaning method | Difficulty | Efficiency | Risk of data loss |
|---|---|---|---|
| Through the call log | Low. | Medium | Low. |
| Through the Security App | Medium | Tall. | Medium. |
| Engineering menu | Tall. | Maximum | High-pitched |
| Resetting settings | Medium | Complete. | critical |
Removing hidden and blocked numbers
Special attention should be paid to calls from hidden numbers or those that were blocked by the antivirus MIUI. These entries are often not displayed in the general log, but occupy a place in the phone's database. To access them, you need to open the Security application and select the Antispam or Blacklist section.
This is where you store the log of all blocked calls and messages, and if you click on the gear icon or menu in the corner, you'll find "Block List" or "Block Log" and if you select the unneeded records, click "Delete" and this action will clear the history of communication attempts that have been sifted out by the system.
If you use third-party numbering apps (like GetContact or NumBuster), their logs are cleaned separately within the apps themselves.The Xiaomi Redmi Note 7 system cleanup will not affect data stored on third-party servers or in their local cache.

Cleaning through the Engineering Menu and ADB
For advanced users who want to get the most out of it, there is a method of cleaning through the engineering menu or the ADB command line. This method allows you to directly interact with the call database without going through the graphical interface. Be careful: wrong actions here can disrupt the communication module.
To enter the engineering menu, open the Phone app and dial ##4636##. From the menu that opens, select "Phone Information." Although there is no direct "Delete All" button, you can reset your network settings, which sometimes clears the connection cache.
A more radical method is to use ADB from your computer, plug the phone in USB debugging mode and execute a command to clean the call database, which requires the developer mode to be on.
adb shell pm clear com.android.providers.contactsPerforming this command will reset the Contacts and Phone Book app to factory status. All saved contacts, if not synced to the cloud, will be permanently deleted along with your call history. So make sure to back up your data before using this method.
⚠️ Note: Contact Provider Data Reset Team will delete the entire phone book. Use this method only if you understand the risks and have backup.
Google Synchronization and Cloud Tracks
Even after cleaning the log on the Xiaomi Redmi Note 7, your call history can be saved in your Google account, Google automatically syncs this data for easy recovery when changing phones, and to delete it completely, you need to go to your account settings.
Go to Settings → Accounts and Sync → Google. Find Contact Sync or go to Google Contacts via your browser. In Data Management or Activities, you can find your call history and delete it from there.
Disabling sync will prevent old records from reappearing after cleaning the phone, an important step for those who want complete digital hygiene. Without this step, the phone can recover deleted records from the cloud the next time it connects to the Internet.
💡
Deleting your call history completely requires cleaning not only your local log on your phone, but also your cloud-based copies in your Google account.
Resetting settings as a last resort
If none of the methods worked or you are preparing the phone for sale, the only guaranteed way to remove all traces of activity is a full reset (Wipe Data).This procedure will return the Xiaomi Redmi Note 7 to factory status by removing all user data, apps and logs.
To perform the reset, go to Settings → About Phone → Reset. Select “Clear All Data.” The phone will reboot and start as new. This process takes a few minutes and requires a battery charge of at least 50%.
Once reset, the device will be clean, just like the day it was purchased, and there will be no trace of your calls, messages or apps on it, and that's the only way to be 100% sure of your privacy when you transfer the device to another person.
