Searching for stored audio recordings of conversations on Xiaomi smartphones, in particular on the popular Redmi 4X model, often causes difficulties for users because of the specifics of the MIUI shell. Unlike standard Android devices, where everything lies in plain sight, Xiaomi’s system hides this data in system folders, access to which may be limited or simply not obvious to the average owner. Understanding the structure of the file system of your gadget is the key to quickly finding the necessary information.
In this article, we will discuss in detail where files are physically located after a call is completed, how to change the default way they are saved, and what to do if records suddenly stop appearing. The Android file system has a clear hierarchy, and navigation requires attention. You will learn to find the right tracks both through the built-in Explorer and when connecting your smartphone to your computer.
It is worth noting that the location of files may depend on the version of the installed firmware MIUI. On older versions, which are often on the Redmi 4X out of the box or installed by users for stability, the paths may differ from current global builds. However, the basic principle remains the same: records are not scattered randomly, but folded into strictly designated directories.
Standard paths to folders with records in the system
By default, all audio recordings created by a standard Phone or Recorder app are placed in the device's internal memory. If you're looking for where the system sent the file after the call, you should look at the root directory of internal memory. Most often it is a folder with a name. MIUI, inside sound_recorder. This is where the main array of audio files accumulates.
But if you're interested in phone records, not dictaphone notes, it might be a different path. MIUI They're stored in a folder. call_rec, which may also be located within the directory. MIUI It's important to distinguish between these two types of records, because the applications for reproducing and managing them may be different.
⚠️ Warning: Do not delete files from system folders manually unless you are sure of their purpose.android_secure or system logs may cause malfunction of the call application.
For quick access to the desired file, you can use the built-in file search. Type in the Explorer search extension.m4a or.3ga - these are the formats most often saved conversations on Xiaomi Redmi 4X. This will filter out excess media files and find only audio recordings.

The main way to record conversations: Internal memory → MIUI → sound_recorder → call_rec (or similar folder depending on the version MIUI).
Search for records through built-in conductor
The most convenient way to find the file you want without connecting your phone to your computer is to use the regular Explorer app, which is preinstalled on every Xiaomi device and has a user-friendly interface for navigation. To get to the right place, open the application and go to the Fiddler or Internal Drive tab.
The algorithm of actions is as follows:
- 📂 Find and open a folder with the name MIUI.
- 🎙️ Inside, find the directory. sound_recorder.
- 📞 Look for the file. call_rec or files prefixed with date and time of call.
- ▶️ Click on the file to listen to it or copy it to another location.
If there are no files in the specified location, check the settings of the call application itself. The recording function may have been disabled, or the save path has been changed by the user earlier. It is also worth checking if files are hidden. In the Explorer settings, there is an option to "Show hidden files" that can help you see the system directories.
Sometimes users are faced with a situation where files are available but they are not played. This may be due to the lack of a suitable codec, although MIUI usually has a universal player built in. In this case, try opening the file through a third-party audio player, such as VLC or MX Player, which are available on Google Play.
Access to files via computer (USB-regime)
The most convenient way to mass-copy or archive records is to use a computer. 4X to a PC or laptop by USB-On the screen of the smartphone will appear a notification about the mode of connection — select "Share files" (MTP). After that, a new device will appear in my computer.
Navigating folders from a computer is exactly like navigating through the built-in conductor, and you'll see the same directories: Internal Storage. MIUI > sound_recorder. Here you can copy files to your hard drive, rename them for convenience or send them by email.
Using a computer has another advantage: it can use software to recover deleted files if a record is accidentally erased. While a phone is connected in MTP mode, some utilities can scan its memory. However, deep recovery often requires Root rights, which are difficult to obtain on modern smartphones.
⚠️ Warning: When connecting to unknown public computers, be careful. Do not select Debugging by USB", if you don’t trust the device you’re connecting to to avoid potential data breaches.
If the computer can't see the phone, check the cable. Cheap cables are often just for charging and don't have data lines. Use the original cable or quality analog to ensure a stable connection for heavy audio files.
Configuring preservation paths and formats
Users often ask if it is possible to change the location of the records, for example, to transfer them immediately to the site. SD-In the standard setting. MIUI This option may be missing or hidden, but in some firmware versions, you can change the path by settings for Record or Recorder".
To change the recording format (if this option is available in your version of MIUI), follow the following steps:
- 📱 Open the application "Phone" or "Dictorphone".
- ⚙️ Click on the menu button (three dots or gear) and select Settings".
- 💾 Find the item "Record quality" or "Format".
- 🔄 Choose your preferred option: MP3, M4A or AMR.
AMR takes up less space but has lower sound quality. M4A or MP3 format provides better speech intelligibility, which is critical for important conversations, but files take up more space in Redmi 4X memory. The choice depends on your priorities: saving space or audio quality.

Table of formats and characteristics of records
Understanding the differences between file formats will help you better manage your device’s memory, and here is a comparison table of the main formats used in Android and MIUI.
| File format | Sound quality | File size | Compatibility |
|---|---|---|---|
| AMR | Low (optimized for speech) | Minimum | High (systemic) |
| M4A (AAC) | High. | Medium. | High (universal) |
| MP3 | High. | Medium/Large | Maximum |
| WAV | No compression (maximum) | Very big. | Medium |
As you can see from the table, for long conversations, the most rational format is M4A or AMR. They provide a good balance between the intelligibility of the interlocutor’s voice and the volume occupied. WAV format on a mobile device like Redmi 4X is not advisable to use due to the fast memory consumption.
Solving problems with lack of records
The most common problem faced by Xiaomi owners is the lack of recordings after a call. Before panicking, you need to check the basic settings. Make sure that the automatic recording function is enabled. To do this, go to the Phone app, click on the settings gear and find the "Call Record" item.
The following options should be active in this menu:
- ✅ The "Call Record" switch should be switched on.
- ✅ Selected "All numbers" or added specific contacts.
- ✅ Checked the availability of free space on the device.
If the settings are correct, but the record is not, the MIUI power saving system may have intervened, it could have killed the recording process to save battery power. Add the Phone app to the power saving exception list and let it auto-start. This often solves the problem on older models.
⚠️ Note: In some regions (e.g. the European Union), the recording function may be software-disabled by the manufacturer due to privacy laws.
It's also worth checking the app's permissions. Go to Settings → Apps → Phone → Permissions. Make sure the app has access to the microphone and the device's memory. Without those permissions, recording is technically impossible.
