Owners of the Redmi 4 series’ budget-friendly but reliable smartphones often face the challenge of cleaning up their phone book logs. Over time, the list of incoming and outgoing calls grows to hundreds of records, making it not only difficult to find the right contact, but can also take up valuable space in the device’s system cache. Call history clearing is a basic digital hygiene procedure that every Android user should be able to do.
In this article, we will take a look at all the ways you can delete records, from the standard menu to the use of hidden system functions. The MIUI Call Log has its own storage features that differ from pure Android. Understanding these nuances will help you avoid accidentally deleting important information or losing contacts during synchronization.
We will also touch on security and privacy issues, as complete deletion of history may be required when selling a device or transferring it to another person. Xiaomi Redmi 4, despite its age, remains a popular device, and the issues of optimizing its operation are still relevant.
Standard cleaning through the application "Phone"
The most obvious and safe way to remove your call history is to use the app's built-in functionality. In the MIUI shell that's installed on Xiaomi Redmi 4, the call interface has its own features. To start cleaning, you need to open the standard Phone app and go to the tab with the watch or the list of recent ones.
Press and hold your finger on one of the entries in the list. This action activates the highlight mode. After that, additional control buttons will appear. You can select specific numbers to delete or use the mass selection function. In the upper corner of the screen, often there is an icon of a basket or a menu with three dots, where the option to delete everything is hidden.
⚠️ Note: When you delete entries through the standard menu, they disappear from the log, but can remain in cloud sync if it's enabled.Check your Mi or Google account settings to make sure the story doesn't automatically recover.
If you only need to delete certain types of calls, such as only missed ones, use a filter. Click on the filter icon (usually looking like a funnel or slider) at the top of the call screen. Select Missed category, then highlight everything and delete. This will help quickly clear the list of unnecessary notifications about calls you haven't answered.
To completely clean the list, follow the following steps:
- 📞 Open the Phone app and go to the History tab.
- 🖱️ Press and hold any number until the selection menu appears.
- ✅ Click the "Select All" button in the top corner of the screen.
- 🗑️ Click on the basket icon and confirm the action.
Using the application storage cleanup menu
Sometimes standard deletion doesn’t work properly because of software failures or cache overflows. In such cases, the application management system menu comes to the rescue, which allows you to erase not only the visible list, but also hidden logs that may occupy space in the memory of Xiaomi Redmi 4.
In the settings menu, find the App or All Apps. In the list of all installed programs that opens, you need to find the Phone system application (green handset icon). It is important not to confuse it with contacts or messages. After entering the application menu, click the Clean or Memory button at the bottom of the screen.
You'll see a window with two basic options: One is Clear Cache, which is secure and only deletes temporary files, speeding up the application, and the other is Clear Everything or Reset, which completely destroys the database of call logs, returning the application to the "post-purchase" state.
☑️ Check before resetting the application
This is especially effective if the call list is "glutching" or displaying the wrong time, but it's worth remembering that after this procedure, the story will be empty and it will not be possible to restore it with standard means. It is a radical but effective way to solve problems with the software of the call.
Removal via the control menu SIM-card
Many users forget that call history can be duplicated and stored directly on the chip. SIM-Even if you cleaned the log in your phone's memory, old entries can pop up again or take up space on the SIM, limiting the retention of new contacts.
In some versions of the firmware MIUI Redmi 4 Access to Control SIM-The map is on the way of settings → System and device → SIM-You can find additional or call settings here, and if you don't have one explicitly, try dialing the dialer code that we'll talk about in the next section, or using the engineering menu.
To clean up the memory SIM-Maps follow the following steps:
- 💾 Go to the call settings through the system menu.
- 📟 Select Additional Settings or Settings SIM.
- 🗑️ Find the option "Call Management" or "Journal" SIM".
- ❌ Click "Clear Call Log" and confirm the action.
⚠️ Attention: Cleaning the journal on SIM-The card doesn't affect the history in the phone's memory, and vice versa. These are two independent data stores.
It is worth noting that (capacity) of memory SIM-The cards are very small, usually containing no more. 20-30 However, overflowing this buffer can lead to errors in the identification of the number or problems with displaying the name of the caller.
Working with engineering menus and codes
For advanced users who want to take full control of their Xiaomi Redmi 4, there is an option to use the engineering menu.This is a hidden part of the system designed to test hardware, but it also allows you to manage logs and logs. Access is provided through a set of special USSD-codes in the app.
The most common code to log into the engineering menu of MediaTek and Qualcomm devices (which are used in Redmi 4) is ##4636##. Once you enter the last character, the menu will open automatically. You are interested in the Phone Information section. Here you can see the statistics and, in some versions of the firmware, find the reset button for test information.
What if the code doesn't work?
Another useful code for cleaning logs is ##7780##. It is designed to reset app settings and delete system data, but does not delete personal files, photos or music. It is a soft reset that often solves problems with hanging the call list. Before using it, make sure you understand the consequences.
Basic codes for working with logs and calls:
- 📟 ##4636## - Phone information menu and statistics.
- 🔄 ##7780## - Reset application settings and delete system data.
- 📶 ##3646633## - Alternative login to the engineering menu (CIT).
- 📞 ##8255## - Launching GTalk (may contain logs).
Using these tools requires caution. Changing the settings in the Radio Information or Cell Info section can cause the phone to stop catching the network. If you are not sure about the purpose of a particular button, it is better to refrain from pressing. The purpose of using these codes in the context of this article is only access to hidden cleaning functions if standard methods do not work.
Comparison of data cleanup methods
The choice of cleaning method depends on your ultimate goal: whether you just need to make room, hide information from prying eyes or fix a software failure. Below is a table that will help you navigate and choose the most appropriate way for your situation on the Xiaomi Redmi 4.
| Cleaning method | Difficulty | Efficiency | Risk of data loss |
|---|---|---|---|
| Through the phone app. | Low. | Average (visible list only) | No. |
| Cleaning the cache/memory | Medium | High (full reset of the magazine) | Low (contacts retained) |
| Removal of c SIM-map | Medium | Medium (locally only on the sim) | No. |
| Engineering menu | Tall. | Maximum (system logs) | High (in case of wrong actions) |
As you can see from the table, the first method is enough for everyday use. However, if you are preparing a phone for sale or transfer to another person, it is recommended to combine cleaning through the application and resetting data through settings. This ensures that the new owner will not be able to recover your call history using simple methods.
It is also worth considering that some methods may not be available on certain versions of Android or MIUI. For example, on global firmware, access to the engineering menu may be limited compared to the Chinese versions.
💡
Before selling your phone, not only clear your call history, but also complete a Factory Reset via the Recovery and Reset menu, which will delete all accounts and personal data, making the device clean for the new owner.
Recovering Deleted History and Working with Backups
Sometimes the reverse happens: you cleared the call list by accident, and now you need to restore an important number. Fortunately, the Xiaomi ecosystem and Google services provide powerful backup tools. If you had sync enabled, your data could be saved to the cloud.
To check cloud backups, go to Google Contacts or Google account settings on your phone, where you can track your history and, in some cases, restore deleted contacts, although the history of the call log (time and duration of calls) is more difficult to recover, often stored locally in a database file, which is permanently erased when deleted unless there is a special backup.
However, if you have used the Mi Cloud app or third-party call backup software (like Call Logs Backup & Restore), it will take a couple of minutes to recover. Just launch the app, select the restore point and click Restore. The system will request log rights, and the list will be returned to its original state.
⚠️ Warning: Restore call history backup will completely replace the current log.All new calls made after backup creation will be lost or duplicated.
To avoid this in the future, set up automatic backups. In your Google account settings, look for Sync and make sure Contacts and Telephony is activated. This doesn't always save a detailed call log, but it does ensure that the numbers themselves are saved, which is often more important than the call time.
💡
Regularly backing up is the only reliable way to protect against the accidental loss of important call information.
