The Xiaomi Redmi Note 4 is still one of the brand’s most popular smartphones, despite the launch of new models, and many users are faced with the need to find phone records — whether for work, personal use or legal purposes. However, standard MIUI tools are not always obvious, and record files can be “hidden” in unexpected folders.
In this article, we’ll look at all the ways you can find records, from built-in Redmi Note 4 features to third-party apps and hidden system folders, where audio files are stored, how to extract them if they’re not displayed in the gallery, and what to do if the recording “disappears” after a firmware update, and focus on the nuances of working with MIUI 8/9/10, the most common versions for this model.
1. Built-in call recording function in MIUI: where to look for files
On the Redmi Note 4, conversation recordings can be turned on automatically or manually, depending on your settings. By default, files are saved to the system folder, but their location depends on the MIUI version and regional firmware.
- 📁 folder MIUI/sound_recorder/call_rec — The file manager path is the standard storage location for most firmware versions. → MIUI → sound_recorder → call_rec.
- 🔊 Files with the.amr extension or.mp3 — Records usually have names in format call_YYYYMMDD_HHMMSS.amr, where YYYYMMDD — date, HHMMSS — talk-time.
- 📱 The Recorder app - sometimes the recordings are duplicated here, even if they're made during the call. Open the app and check the Calls tab».
If the folder call_rec Empty, try to enable the display of hidden files in the file manager (in the file manager). MIUI This is done through the “Settings” menu. → Show hidden files. Also make sure that the recording was actually done – on some firmwares, the function is disabled by default.
💡
If the recording is not saved, check the settings of the Phone app: Phone →... (menu) → Settings → Call record.
2. Search through file manager: step-by-step instructions
The MIUI system file manager is the most reliable way to find records if you're not using third-party applications.
- Open the Files app (the folder icon on the home screen).
- Go to the Local Storage tab (or Internal Memory).
- In the upper right corner, press three dots (⋮) → «Show hidden files».
- Scroll down the list of folders and find MIUI → sound_recorder → call_rec.
- If the folder is not, try alternative ways: Recordings/Call — custom-made. Android/data/com.android.providers.media/call_recordings — rare but occurring.
«Sorting → By date»
If files are found but not played, try copying them to your computer and opening them via VLC Player or Audacity – sometimes.amr codecs are not supported by standard players.

3.Use of the Dictator app for listening
MIUI has a built-in Dictatoron app that sometimes duplicates call records, which can be a lifesaver if files aren't displayed in folders. Here's how to use it:
- 🎤 Open the Dictophone app (if it is not on the main screen, search through the system search).
- 📂 Go to the Calls tab (or Call Records tab – name depends on version) MIUI).
- 🔍 If there is no tab, click on three lines (☰) top-left → «Categories» → «Calls».
- 📅 The recordings here are sorted by date. Click on the right one to listen to or share it.
Note that some firmware stores records from the Dictophone separately from system call files. If you find the record here, but you don't see it in the folder. call_rec, So it was done manually through a voice recorder, not automatically during a conversation.

4. Third-party applications for recording and searching calls
If the built-in MIUI tools fail, third-party apps will come to the rescue, not only recording calls, but also making it easier to find old files.

|---|---|---|---|
| Cube Call Recorder ACR | Recording both sides of the conversation, cloud storage, search by numbers | /CubeBackup/ or /ACR/ | Google Play |
| Call Recorder – Automatic Call Recorder | Automatic recording, contact tagging, exporting to the cloud | /CallRecorder/ | Google Play |
| Boldbeast Call Recorder | Support for older versions of Android, writing in.mp3 or.wav format | /Boldbeast Recorder/ | Google Play |

5. Recovering deleted call records
If the recording was deleted accidentally, you can try to restore it, and success depends on how long it has been since it was deleted and how actively the memory of the smartphone was used.
- 🗑️ Check the Recycle Bin in the File Manager MIUI (The.Trash or Recycle Bin folder, which is stored for up to 30 days.
- 🔍 Use recovery software: DiskDigger scans internal memory for deleted audio files. Recuva (for computer) – if you connect Redmi Note 4 as a drive.
- ☁️ Check cloud backups: Mi Cloud – if file sync was enabled. Google Drive – if backup was used through third-party apps.
Important: After deleting the record, immediately stop writing new files to the device (photos, videos, downloads), which will increase the chances of recovery, as deleted data is overwritten with new ones.
⚠️ Note: Recovering data from the internal memory of Redmi Note 4 without root rights is possible only for files that have not yet been overwritten.
6.Disorders with Redmi Note 4 call recording: causes and solutions
Sometimes records don't get saved or disappear for no apparent reason, and let's look at the typical problems and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|

7. Alternative methods: cloud services and backups
If the records are not found on the device itself, check the cloud services. Many users forget that MIUI can automatically sync files to Mi Cloud or Google Drive.
How to check:
- 🌐 Mi Cloud: Open Settings → Mi Account. → Mi Cloud. Check the backup or Files section. Look for folders with names call_rec or sound_recorder.
Google Drive
- Open the Google Drive app or the web version of drive.google.com.
- In the search box, enter call_rec or.
- Check the Backups section (if synchronization through third-party apps is enabled).
If you’ve used cloud-based call recording apps like Cube Call Recorder, check their accounts. Many services store records for up to 30 days even after being deleted from the device.
⚠️ Note: When recovering data from the cloud, make sure you have enough space on your device. Large archives of records can take several gigabytes.
