Where to save your Xiaomi conversation records with MIUI 12: a complete guide to finding and managing files

Recording phone conversations on Xiaomi’s MIUI 12-enclosed smartphones is a useful feature for capturing important conversations, interviews, or evidence. However, many users are faced with the problem of where exactly are these audio files stored? Unlike the newer versions of MIUI (13/14), where the path to records is often obvious, in MIUI 12, the location of files can vary depending on the device model, firmware version, and even regional settings.

In this article, we’ll look at all possible storage locations, from standard folders in internal memory to hidden system directories, how to find files through Explorer, why they can disappear after an update, and what to do if the record is not saved at all, and focus on the nuances of working with the Redmi Note 9/10, Mi 10/11 and other popular devices on MIUI 12.

Standard location of conversation records in MIUI 12

By default, the Dictophone app (or built-in call recording module) saves files to one of two folders:

• 📁 /storage/emulated/0/MIUI/sound_recorder/call_rec/ — basic catalogue for most models.
• 📁 /storage/emulated/0/Recordings/Call/ — alternative path on some firmware.

The files are formatted.m4a or.amr and named by template: Call_YYYYMMDD_HHMMSS_XXXXXXXXXX.m4a, where XXXXXXXXXX — The phone number of the interviewee: Call_20231015_143022_79123456789.m4a.

To open the folder:

1. Run the standard Files app (Blue folder icon).
2. Go to Categories → Audio or Internal Memory → MIUI.
3. If the folders sound_recorder No – enable the display of hidden files in the Explorer settings.

Why can’t the records be in the standard folder?

If you did not find the files in the specified ways, the reasons may be as follows:

• 🔄 Automatic cleaning: MIUI 12 Default deletes records older than 30 days (set up in Recorder) → Settings → Autocleaning).
• 📱 Regional restrictions: Some firmware for India or the EU has system-level call recording disabled.
• 🔧 Application failure: If the recording is interrupted, the file may be saved in a corrupted form (size 0 KB).
• 📲 Third-party applications: If you use Cube Call Recorder or ACR, The files are stored in their own folders.

Check also the /storage/emulated/0/Android/data/com.android.soundrecorder/ folder, sometimes the entries are duplicated there. If the folder is not there, you may have kernel-level writing disabled on your device (relevant to some POCO models on MIUI 12).

💡

To avoid losing records, disable autocleaning in the Recorder settings and regularly copy files to the cloud or PC.

How to enable the display of hidden folders and system files

MIUI 12, by default, hides system directories, including those where records may be stored, to see them:

1. Open the Files app.
2. Slip on three dots in the upper right corner → Settings.
3. Activate the switch to show hidden files.
4. Go back to the root directory of internal memory and check the folders: 📂 MIUI → sound_recorder 📂 Android → data → com.android.soundrecorder

If even after that, there are no records, try connecting your smartphone to your PC via USB in File Transfer (MTP) mode and using Windows Explorer or macOS. Sometimes the F2FS file system used in Xiaomi displays files incorrectly in the standard MIUI Explorer.

Alternative ways to access records

If standard methods do not help, use one of these methods:

To use ADB, run on the PC command line:

adb shell ls /sdcard/MIUI/sound_recorder/call_rec/

If the folder exists but is empty, try searching for the files by mask:

adb shell find /sdcard/ -name "Call_*.m4a"

Problems with keeping records: causes and solutions

If the records are not saved at all, check the following points:

• 📵 Lack of permission to record: B MIUI 12 Dictaphone application needs permissions to access microphone and storage. → Annexes → Permits.
• 🔇 System Blocking: Some EU firmwares prohibit recording calls (directive) GDPR). Solution – firmware global or Chinese version MIUI.
• 📱 Conflict with other applications: Antiviruses (Avast, 360 Security) or optimizers can block recording.
• 🔋 Saving charge: In the mode of ultra-saving MIUI 12 suspends background processes, including recording. Turn off optimisation for recorder.

If the problem persists, try resetting the Dictophone app settings:

1. Go to Settings → Applications → Application Management.
2. Find a recorder (or Sound Recorder).
3. Slip the vault. → Clear the data.
4. Reset the device.

💡

On Xiaomi models for the European market (EEA), call recording is often blocked at the firmware level, the solution is to install a global or Chinese version of MIUI via Fastboot.
