Xiaomi Redmi Note 4 is still a popular smartphone among users who value reliability and functionality. One of the most popular features is recording phone conversations, but not everyone knows where the device stores these files. Unlike modern models with cloud services, Redmi Note 4 uses local storage, which creates risks of data loss when reset or breakage.
In this article, we will look at all possible storage locations, from standard MIUI folders to hidden system directories, and learn how to transfer audio files to a computer, restore deleted records and set up automatic backups, and pay special attention to the nuances of working with different versions of the firmware - MIUI 8/9/10, as the location of the files may vary.
Standard storage locations for Redmi Note 4 call records
By default, the Call Recorder app (built into MIUI) stores files in the device's memory. The path depends on the firmware version and user settings. In most cases, the audio is placed in the folder:
/storage/emulated/0/MIUI/sound_recorder/call_rec/If you use a memory card as your primary storage, the path will change to:
/storage/XXX-XXXX/MIUI/sound_recorder/call_rec/where XXX-XXXX — Your unique identifier SD-Note: Please note: Redmi Note 4 s MIUI 8 The folder can be called simply a recorder without prefixes. sound_.
- 📁 folder MIUI — Main directory for system records (including calls).
- 🔊 File format: usually.amr or.mp3, less.m4a.
- 📱 Access via Explorer: Use Files (standard application) or ES Conductor.
⚠️ Note: If you can't find the folder call_rec, Check the settings of the Record application. In some firmware, you can manually change the path through Settings. → Preservation site.
How to find records through the built-in MIUI conductor
The easiest way is to use the standard Files app (a blue folder icon) and open it and follow the instructions:
- Go to the Category tab (bottom of the screen).
- Select the Audio section.
- In the list, find the Records folder or Call Recorder.
- Sort files by date to quickly find the right conversation.
If there are many records, use the search by name: MIUI Call files are often named by template Rec_YYYYMMDD_HHMMSS.amr, where:
- YYYYMMDD - date (year, month, day)
- HHMMSS is the time (hours, minutes, seconds).
For convenience, you can create a folder shortcut on the home screen: click on the folder call_rec In the conductor, select Add to the main screen.

Hidden system folders: where else can records be stored
In some cases, call records are not stored in a standard folder, but in hidden directories.
- 🔄 You've been updating the firmware with MIUI 8 on MIUI 9/10 (paths could have changed).
- 📱 Used third-party recording apps (e.g. Cube Call Recorder).
- 🔧 Manually changed the storage settings in the engineering menu.
Check out the following alternative paths:
| folder | Description | When used |
|---|---|---|
| /data/data/com.android.providers.media/databases/ | Database of media files, including records | Requires root rights to access |
| /sdcard/Recordings/ | Universal folder for records (including calls) | Older versions of MIUI or custom firmware |
| /storage/emulated/0/Android/data/com.miui.voicerecord/ | Dictator (sometimes used for calls) | If the recording is conducted through a voice recorder, and not specialized software |
| /storage/emulated/0/Download/CallRecordings/ | Folder for records created by third-party applications | When using Call Recorder – ACR or similar |
To access hidden folders (e.g. /data/), you need root rights or special applications like Root Explorer, and without them, you will only see standard directories.
⚠️ Note: Modifying files in the folder /data/ If you're not sure, rootless can cause system failures.

If.amr records are not played on a PC, install the FFmpeg codec or convert files to.mp3 through online services like Online-Convert.
Recovery of Deleted Call Records
If you accidentally delete a record, you can try to restore it, and success depends on how long it has been since it was deleted and whether the device's memory was used after that.
1. Through recovery applications
Download Google Play utilities like DiskDigger or Recuva (for PC).
- Install the application and give access to the memory.
- Select the file type - Audio.
- Start a deep scan (it will take 10–30 minutes).
- Find files with the.amr or.mp3 extension and restore them.
2. Through a backup of MIUI
If you have previously created a backup through Settings → Additional → Backup, restore the data:
- Go to Settings → About Phone → Backup.
- Select the last copy and click Restore.
- Please indicate that only Call Records (if available) must be restored.
Critical: After deleting the records, DO NOT save new files to the device (photos, videos, apps) – this reduces the chances of recovery.
⚠️ Attention: Recovered files may be corrupted. Before important conversations, set up automatic copying of records to the cloud (for more on this in the next section).
Automatic backup of records to the cloud
To avoid losing records when your phone crashes or resets, set up automatic uploads to the cloud. On Redmi Note 4, you can do this through:
1. Mi Cloud (official decision)
Xiaomi offers 5GB of free cloud storage to enable synchronization:
- Go to Settings → Accounts → Mi Cloud.
- Sign in or create a Xiaomi account.
- Activate the option to sync records (if available).
- Manually copy the folder. call_rec Mi Cloud → Files.
2. Google Drive (Universal Option)
Install the Google Drive app and set up automatic download:
- Open Google Drive → Settings → Backup.
- Select the folders to copy and add MIUI/sound_recorder/.
- Please indicate the frequency of copying (e.g., Daily).
To save traffic, use Wi-Fi-only downloads, and you can also configure recording compression before copying (via applications like FolderSync).
💡
Cloud backup is the only way to guarantee record retention when a phone is stolen, broken or reset.
