How to record a phone conversation on a Xiaomi smartphone

Modern Xiaomi smartphones have powerful functionality, but the issue of saving important phone conversations often puts users at a loss.The built-in capabilities of the Android operating system and the MIUI shell are periodically changed due to Google privacy policy updates. This leads to the fact that standard methods can stop working or require complex configuration.

In this article, we will discuss the current ways to activate the voice recorder function during a call. You will learn how to configure automatic dialog saving, which codecs are better to choose for sound quality and what to do if the regular feature is not in your firmware version.

We will also discuss the use of third-party software that circumvents system constraints, and it is important to understand the difference between native tools and third-party applications to choose the most reliable option for your device model.

Built-in recording capabilities in MIUI and HyperOS

Xiaomi has traditionally equipped its smartphones with a powerful regular phone app, depending on the firmware region (Global, EEA, China, Russia), the functionality may vary, and in most cases, the recording function is already built into the system, but by default is hidden or disabled.

To activate, you need to go to call settings. The interface may vary slightly on different versions of MIUI, but the logic remains the same. The user gets access to a flexible settings system that allows you to control the behavior of the recorder.

  • 📱 Open the phone application (green handset).
  • ⚙️ Click on the three dots in the upper right corner or go to Settings».
  • 🎙️ Select the "Call Recording" option).

This is where the key difference between firmware versions lies: in some regions (such as India or China), the feature is enabled by default, while in European versions (EEA), it can be completely removed from the application code due to GDPR laws.

Once the option is enabled, the system will start saving all incoming and outgoing calls to the device's memory. MIUI/sound_recorder/call_rec or available through a built-in voice recorder player.

Step-by-step activation of automatic recording

Manually turning on the recorder while you're talking is inconvenient, because you can forget to press the button or you can't do it at the right time, and automation solves this problem, and you need to set the settings in the call record menu correctly.

In the settings menu, find the Auto Record switch, and when you activate it, you can choose to record all calls or only certain numbers, saving memory space and only important information.

Pay attention to the notification settings. The system can alert the person to start recording with a voice message. In some regions, you can't turn off this warning without using modified system files.

Sound quality is directly dependent on the codec you choose. You can often find a choice between AMR and AAC on the settings menu. The first format takes up less space but has lower quality. The second one provides clean sound, but the files will weigh more.

Configuring codecs and audio formats

Choosing the right audio compression format is critical if you plan to store an archive of conversations for long periods of time or use them as evidence. The standard AMR-NB (Narrow Band) codec is optimized for speech, but cuts the frequencies, making the voice metallic.

The AAC (Advanced Audio Coding) codec provides a much wider bandwidth. On modern Redmi and POCO smartphones with good microphones, the difference will be palpable. However, using high-bitrate formats consumes battery power faster.

RecommendationFor long archivesFor important negotiationsOnly for critical data

If there is no codec choice in the standard menu, the system defaults to the optimal balance for your model. Forced change of this parameter through the engineer mode menu is not recommended, as it can lead to instability of the communication module.

💡

For maximum compatibility with other devices (for example, for listening on an old computer), choose the AMR format, it opens with almost any media player without installing additional codecs.

Solving problems with lack of function

Often, users are faced with a situation where the item “Record calls” simply does not appear on the menu, which is typical for global firmware released after 2026, where Google severely restricts the access of applications to the microphone during a call.

⚠️ Warning: Attempts to install modified Phone apps from third-party developers carry the risk of personal data leakage.Use only verified sources or official methods.

One legal way is to change the region of the device. Going to Settings Additional → Region and selecting a country where the entry is allowed (for example, Indonesia, India or Singapore) can return the deleted feature. Once the record is turned on, the region can be returned back.

Another method is to use third-party voice recorder apps that have special permissions to intercept audio streams, but on Android 11, 12, 13 and 14, this is unstable, and the system can block recordings or record silence instead of the voice of the interlocutor.

  • 🔄 Try changing the region in the system settings.
  • 📲 Install the Cube app ACR (requires special needs. capabilities).
  • 🔧 Use Developer Mode to Turn Off Battery Optimization for Dictaphone.

If you're using HyperOS, energy saving algorithms can aggressively kill the recording process, you need to fix the voice recorder app in memory and allow auto-start.

Use of third-party applications

When regular funds are powerless, specialized utilities come to the rescue, a niche that has long been dominated by Cube ACR, which can bypass restrictions using Accessibility Service.

It requires careful setup to work properly, and you have to give the app maximum permissions, including access to the microphone, phone, and device control, without which you can only record it from your voice, and the person you're talking to won't be heard.

Why have third-party apps stopped working?
Since Android 10, Google has shut down direct access to the audio stream of telephony (Audio Record API), where apps are forced to record sound through a microphone, which leads to recording of ambient noise, or use sophisticated hacks through accessibility services, which Google constantly patches in new security updates.

Alternatively, applications like TapeACall or Call Recorder — ACR. They often use a conferencing method to record, where the application calls to the recording server and merges the lines, and the downside is paid subscription and dependency on the quality of mobile communication.

When installing any third-party software, read reviews carefully and check for permissions requested. The call recording app should not require access to your gallery or contacts without an explicit need.

Where are the records stored and how to find them

After successful writing, the file is stored in the internal memory of the smartphone. The standard path to the directory usually looks like internal memory./MIUI/sound_recorder/call_rec. Depending on the Android version, the path may change. Android/data/com.android.phone/files/CallRecord.

You can find files through the standard Files Explorer or Explorer. The Recorder app also has a Records tab, where all audio files, including phone conversations, are sorted, and they are often marked with a special tube icon.

For fast file transfer, use the built-in MI Share or messaging feature. The file format is usually compatible with Telegram, WhatsApp and email clients without conversion.

If you can't find the files, check the storage settings. SD-a card that is not currently connected, or the path to the folder has been changed in the settings of the voice recorder application itself.

Recording telephone conversations is a subject regulated by the legislation of a particular country. In the Russian Federation, according to Art. 138 of the Criminal Code, violation of the secrecy of correspondence and telephone conversations is prohibited, but there is a nuance: the recording of a conversation in which you participate is usually not considered a violation, unless you distribute it to third parties without the consent of the interlocutor.

In Europe, the GDPR requires all participants to be notified of the start of a recording, which is why Xiaomi’s European firmware often sounds a voice warning.

⚠️ Note: The use of court records as evidence is not possible in all cases; the court may reject the recording if it is proved that it was obtained in violation of the law (for example, a hidden recording without notice).

Always use common sense and respect for privacy, and recording private conversations without the other party’s knowledge can lead to conflict and loss of trust, even if you have not formally broken the law.

For business negotiations, it is recommended to notify the client in advance of the recording, which is not only legally competent, but also increases the transparency of communication.

Frequently Asked Questions (FAQ)

Why can't you hear the person talking to you, just me?
This is a security limitation for Android 10 and higher. The system blocks apps from accessing the internal audio stream. Try to turn on speakerphone or use third-party apps with a "Sound Source: Voice Call (VoIP)" or "Microphone" setting.
Can I record calls from WhatsApp and Viber?
Xiaomi’s regular tools — no, they only work with regular telephony. Messengers need special applications (like Cube ACR with plug-in enabled for VoIP), but their work is unstable due to traffic encryption.
Where is the archive of records stored after resetting settings?
