How to record calls to Xiaomi: full instructions

Modern Xiaomi, Redmi and POCO smartphones offer a wide range of communication features, but the issue of maintaining the audio conversation track is often difficult for users, because Google’s policy on Android is constantly changing, putting restrictions on app access to the microphone and system sounds during calls, which is why standard methods can vary depending on the version of MIUI or the new HyperOS shell.

You don't have to look for third-party apps that are often unstable or advertised, because you already have a powerful conversation capture mechanism built in. If you set up this tool correctly, you can keep important agreements, account numbers, or evidence in high quality. We'll look at all the nuances of this feature, including hidden settings and features of working with instant messengers.

Built-in recording function in the Phone application

The most reliable way to capture a conversation is to use the native Phone app, which is pre-installed on all of the company’s devices. Unlike third-party counterparts, the system solution has deep access to the audio stream, which ensures both interlocutors’ clear sound without unnecessary noise. However, the interface and availability of options can vary depending on regional firmware (Global, China, EEA).

To activate the function, you need to open call settings. Usually the path is: launch the Phone application, click three dots in the corner or gear, then select Call Record. Here you will see the Auto Record switch, which allows you to save all incoming and outgoing calls without you, which is especially convenient for those who often forget to press the Start button manually.

Note the source of sound. Some versions of MIUI have options: Microphone or Call Sound. The first option records sound through the speaker, so the quality depends on the volume of the conversation, the second one captures the system stream directly, providing perfect quality, but may not be available in some countries due to legal restrictions.

💡

In some regions, the "Call Record" option may be hidden, so try changing the region of the device in your system settings to India or Singapore to unlock this feature.

⚠️ Warning: When using automatic recording, be sure to alert the interlocutor that the conversation is being recorded so as not to violate your country's privacy laws.

Automatic mode setting and exceptions

Xiaomi’s flexibility allows you to customize recording scripts to avoid unnecessary conversations with couriers or friends. From the recording settings menu, you can choose to Write only certain numbers or, conversely, Write all but selected ones, which helps save memory space and structure the archive.

To add numbers to the exclusion list or priority contacts, go to the appropriate submenu, where you can manually enter a number or select a contact from the address book, the system will automatically analyze the incoming call and apply a given algorithm of actions, if the number is not found in the lists, the default rule will apply.

You should also pay attention to the file format. The most common codec is used. MP3 or AMR. Format MP3 Provides better quality and compatibility with most players, but takes up more space. AMR-The files weigh much less, which is important for long conversations.

Where to find saved files and how to export them

Once the conversation is over, the file is stored in the internal memory of the device, and you can find it through the standard File Explorer or any other file manager. MIUI/sound_recorder/call_rec or Recordings/call_rec, depending on the shell version.

You can use the Phone app itself to quickly access the list of all records. The dialing interface often has a Record tab where all files are sorted by date and time, and you can listen to a conversation, rename a file, or share it via messenger.

If you plan to transfer the archive to your computer, the easiest way to connect your smartphone to USB and copy the entire folder is to sync with cloud services like Google Drive or Yandex.Disk, if you set up an automatic download of the folder with records.

Recording calls via messengers (Viber, WhatsApp, Telegram)

Recording conversations in VoIP applications (Viber, WhatsApp, Telegram) is technically more difficult due to traffic encryption and Android limitations. Xiaomi's standard call recording feature often doesn't activate automatically when making calls over the Internet.

In some versions of MIUI, there is a hidden ability to record calls from instant messengers via speakerphone, which requires you to turn on the phone app, and make a call by choosing the "Write" option manually, but the sound of the second person can be quiet if you do not turn on the speakerphone.

The alternative is to use the Second Space function or the cloning of applications, where you can install a specialized voice recorder with root rights, but this requires a deep knowledge of the system. For the average user, the most effective way is to turn on the speakerphone and use the built-in voice recorder or second device.

⚠️ Warning: When recording calls in instant messengers via speakerphone, make sure the room is quiet, otherwise background noises will make the recording unreadable.

Problem Solving: No sound or recording doesn't start

A common problem with users is that they record, but only you can hear yourself or there is silence, and this is often due to the location of the microphone and the conversation is quiet, switch the source to the Call Sound in the settings, if this option is available in your area.

Another reason is a conflict with other applications that have access to the microphone. Check the permissions in Settings → Apps → Phone → Permissions. Make sure that access to the microphone and memory is allowed. Also try clearing the cache of the Phone application.

If the write feature is completely absent from the menu, your firmware may be blocked for your region, so you can try changing the region in the system settings (Settings → Additional settings → Region) to a country where recording is allowed by law, such as India or Vietnam.

Using Google Assistant for Dictation

While Google Assistant doesn’t record the conversation itself, it can be useful for capturing key moments through voice notes. However, it’s better to rely on Xiaomi’s native tools to record calls. In recent Android updates, the assistant’s functionality is limited to smart home management and search.

Some users try to use the "OK, Google, turn on the voice recorder" command during a conversation, but this rarely yields a quality result due to the priority of the audio stream.The Xiaomi system recording of calls works at a lower level and intercepts sound earlier than the assistant can do.

So if you're critically important to have a record, don't experiment with voice assistants during an important call. Use the time-tested method of embedded function or, in extreme cases, an external recorder held to the speaker.

💡

System call recording in Xiaomi works more stable than any third-party applications due to direct access to the audio stream of the operating system.

Third-party apps: is it worth the risk?

There are hundreds of apps for recording calls in the Play Market, but since Android 10 and later, Google has closed the API to access the audio stream, which means that third-party programs (Cube ACR, Call Recorder, etc.) often record silence or require complex manipulation of access rights through ADB.

Installing these apps carries risks: they can ask for unnecessary permissions, display ads or contain malicious code. Xiaomi’s built-in solution is free of these drawbacks, as it is part of the system and optimized for a specific hardware.

The only time you should consider third-party software is when you record calls from messengers on older versions of Android, which still have old methods of intercepting sound, but even then, the quality will be lower than that of the system counterpart.

⚠️ Warning: Avoid apps that require root permission to record calls, as this could disrupt Xiaomi’s banking and security applications.
