Xiaomi and Redmi smartphone owners often face the need to capture important information during a call, whether it is confirmation of an order, legal agreements or just valuable advice. Unlike many other Android devices, gadgets with the MIUI shell and the new HyperOS offer unique opportunities for this, but their implementation depends on the region of the firmware. Understanding the nuances of the built-in functionality will allow you to not miss a word.
The recording process can vary dramatically depending on which version of the software is installed on your device. Global firmware versions are often limited by EU law, while Chinese or Russian versions (RU) contain a full set of features. We will analyze all available methods so that you can choose the best one for your situation.
In this article, we will take a closer look at the system’s regular tools, hidden settings and third-party solutions that will help you circumvent restrictions. You will learn how to properly configure file quality and storage settings so that records are always accessible and legible.
Staffing capabilities to record calls in MIUI and HyperOS
The built-in MIUI shell is the most convenient and stable way to capture conversations, and the developers have integrated this tool directly into the Phone app, allowing you to activate the recording with a single touch or automatically when you call in, but the availability of this feature depends on the region chosen when you first turn on the device or update.
If you have an official global firmware (Global) installed, the feature may be hidden or completely absent due to strict privacy laws in Europe.However, versions for Russia, Ukraine, Kazakhstan or China (CN) usually have this module active by default.
If you don't have a Call Record, it means that the program limit is set at the regional settings level, and users often switch from the "Additional" menu to Singapore or India, which sometimes returns the desired functionality without flashing it.
Importantly, recording quality through a regular mechanism is usually better than that of third-party devices, because the system has direct access to the audio stream, and noise reduction algorithms work correctly, cutting off background noise and leaving the voices of the interlocutors clean, which is critical to the legal relevance of such files.
⚠️ Note: In the newer versions of Android (11, 12, 13, 14), Google has implemented strict restrictions on app access to the microphone during a call, which means that even a full-time record can work intermittently or require special permissions depending on the OS version.
The differences in the implementation of the functionality can be seen in the table below, which will help you navigate the capabilities of your version of the software:
| Type of firmware | Presence of function | Automatic recording | Warning of the interlocutor |
|---|---|---|---|
| Chinese (CN) | There is. | Yes. | No (usually) |
| Global (Global) | Often hidden | Depends on the region. | Got it (voice) |
| Russian (RU) | There is. | Yes. | No. |
| European (EEA) | Absent. | No. | N/D |
How to enable automatic recording of conversations
Manually turning on a recording while you're talking is convenient, but you can often forget to press the button at the right time. Automating the process eliminates this risk by allowing you to save all incoming or outgoing calls without you. Set up this feature requires care, since incorrect settings can lead to overflowing memory or writing unnecessary contacts.
To activate the mode, go to the Phone app, click on the three dots in the upper right corner and select Settings. Find the Call Record (or Conversations Record) section, and you will see a control panel where you can set the rules for how the system behaves when a call arrives.
In the settings menu, you'll see a "Record Calls Automatically" switch, activate it, and you'll start a background process that will control the line, and ask the system to specify which numbers to write: all incoming, all outgoing, or only selected contacts from the phone book. Selective recording helps save space on the drive.
☑️ Set up automatic recording
Special attention should be paid to the option “Warn about recording”. If this item is active, your interlocutor will hear a voice message that the conversation is being recorded. For complete confidentiality and secrecy, this option should be disabled if the legislation of your country allows. In some regions, disabling the warning is impossible at the program level.
Files are saved to a standard voice recorder folder or a separate directory. MIUI/sound_recorder/call_rec. The path to them can vary depending on the version of Android, but usually access to the archive is directly from the call log: next to the subscriber number will appear a special cassette icon or microphone.
Setting up quality and file storage parameters
The quality of audio recordings directly affects its legibility in the future. Call recording settings on Xiaomi and Redmi often include a choice of coding format, and the standard format is AMR, which provides good compression and acceptable speech quality, taking up a minimum of space.
However, if you want maximum audio detail, you should look for the option to switch to WAV or AAC. These formats take up more space, but retain the timbre of voice and intonation much better, this is especially important for dictaphone recordings of interviews or important conversations, where every pause matters.
Also in this section, the audio source is configured. The system can offer a choice between recording through a microphone or through an internal audio stream. Recording through an internal stream (if available) gives a clean digital sound without room noise, while the microphone will record all the surrounding sounds, including your voice in the speaker.
💡
To save space, use the AMR format. It compresses speech 10 times stronger than WAV, while keeping words clear.
Remember to check the file saver routinely. By default, they can take up space in internal memory that is often not enough to install applications. In the storage settings, you can specify saving records immediately to the SD card if your smartphone supports this feature, which will prevent overflow of the system partition.
⚠️ Note: When changing the conservation path to SD-Make sure the card has a high write speed (class 10 and above) and slow cards can cause recording interruptions or artifacts to appear in the audio file.
Use of third-party applications for recording
When MIUI is not available or is not working properly, third-party apps come to the rescue. The Google Play Store offers a variety of solutions, but due to Android limitations, they often require complex initial setup, and the Cube ACR app has traditionally been considered the leader in this niche.
The software is based on creating a virtual bridge or using Accessibility to intercept audio, and once installed, the Cube ACR must be given all the permissions it needs, including access to its phone, contacts, microphone, and critically, permission to “over other windows.”
In the settings of the recorder application, you should select the source of the sound "Voice Call" or "Mic" If you choose a microphone, it is recommended to turn on speaker during a conversation for high-quality recording, which will allow the application to capture the voice of the interlocutor through the speaker, since direct access to the line is often blocked by Android security.
- 📱 Cube ACR — powerful application with VoIP support (Viber, WhatsApp, Telegram), but requires fine tuning of sound sources.
- 🎙️ Automatic Call Recorder is a simple solution with automatic upload to the cloud, works well on older versions of Android.
- 🔊 TapeACall – uses conferencing to record, which can be paid and requires a stable internet connection.
It's worth noting that on Android 11 and above, the effectiveness of third-party recorders has been significantly reduced, many of which can only record your voice, and the interlocutor will be heard very quietly or with severe distortions, in which case the use of hands-free communication becomes not just a recommendation, but a necessity.
Why have third-party apps stopped working?
Recording conversations from messengers (Viber, WhatsApp, Telegram)
Modern communication has shifted to instant messengers, and the issue of recording calls via WhatsApp or Viber is becoming more relevant. Xiaomi’s regular voice recorder usually does not automatically capture VoIP calls, considering them simply as media playback rather than a phone conversation.
Cube ACR is one of the few apps that has a special plugin to support VoIP. Once the main application is installed, you also need to install the "Cube ACR App Connector" from the list of recommended add-ons, which will allow the program to recognize incoming calls through Internet protocols.
For successful recording, it is important to properly configure the sound source. In the case of instant messengers, often only recording through a microphone with speakerphone on helps. An alternative is a built-in ekranoplan (screencaster) with recording sound, if your version of MIUI allows you to capture the internal sound of the system during a video call.
The process is, you start a conversation in a messenger, then you fold it and you start a screen or voice recorder. But it's uncomfortable and it requires preparation. More advanced users use Android emulators on a PC, where you can easily set up a record of any sound that goes through the system, but that already requires a computer.
Where to look and how to manage saved records
Once a conversation is recorded, it needs to be found. There are several paths to these files on Xiaomi and Redmi smartphones. The fastest way is to open the Dictophone or Sound Recording app. There are often tabs at the top of the screen, one of which can be called Calls or Conversations.
If you are searching for a file through a file manager, go along the path: Internal Memory → MIUI → sound_recorder → call_rec. It stores all the records made by the regular facility, and files are usually named by the date and time of the call or by the contact name, if it is determined.
The most convenient way to manage records (delete, rename, send) is to use the built-in voice recorder player, which allows you to cut the silence, speed up playback and quickly share the file through instant messengers. Formatting the file name can be changed manually in properties if the system does not do this automatically.
- 📂 The default path: /storage/emulated/0/MIUI/sound_recorder/call_rec/
- 🔍 Search: Use a file search with the.amr or.wav extension.
- ☁️ Sync: Set up the autoload folder call_rec Google Drive or Xiaomi Cloud for safety.
⚠️ Warning: When cleaning your phone's memory through the built-in Cleanup tool, be careful. The system may suggest removing "Large Files" or "Old Records" that may include important conversations. Always check the list before confirming deletion.
💡
Regular backup of conversation records to a cloud server or computer is the only guarantee that important information will not be lost when you reset your settings or break your smartphone.
