Smartphone owners often face the need to keep important information from a phone call, such as confirming an order, making an agreement with a customer, or simply recording a conversation with relatives. Xiaomi Redmi Note 9 is a popular device, but the features of the Android operating system and regional restrictions can make this process difficult.
There are several ways to implement call recording, from built-in system functions to the use of third-party software. It is important to understand that recording a conversation at the software level has its own nuances, depending on the version of the MIUI firmware and regional settings. In this article, we will discuss all the available methods in detail so that you can choose the most suitable for your situation.
It’s worth noting that Google’s security policy has become more stringent in recent years, which limits apps’ access to the microphone while calling, which is why Redmi Note 9 may see different implementations of this feature depending on which version of Android and MIUI is installed on your device at the moment.
Built-in recording function in the Phone application
The easiest and most reliable way to do this is to use the regular Phone app, which is pre-installed on the device. In most global versions of MIUI, this feature is already built in, but by default it can be disabled. To activate, you need to open the application and go to settings, often hidden behind three dots or a gear.
Once you log into the settings menu, you'll need to find the call recorder, where you can choose to run: record all incoming and outgoing calls automatically, or just selected numbers. Auto-write is convenient because you don't have to remember to turn on the function during the call.
⚠️ Note: In some regions (e.g. Europe) due to privacy laws, the automatic recording function may be hidden or require a voice alert to the interlocutor to start recording.
If standard settings don’t allow you to enable the option, it’s possible that your region is defined as a country with strict laws in your smartphone settings, so you can try changing the region in the general settings to Singapore, Indonesia or India, where there are no such restrictions, which often helps unlock hidden interface features.
Recorded files are usually stored in the device's memory and are accessible through a built-in voice recorder or file manager. The sound quality when using the standard method is usually high, since the system has direct access to the audio stream.
Set up automatic recording and file management
To make the recording function more comfortable, it is important to set up the file storage and cleaning options correctly, and the call record menu often tells you whether to alert the caller with an audible signal, which is critically important from a legal point of view in many countries.
Records are managed through the Dictaphone app or directly in the call log, and a special icon usually appears next to the subscriber's number, and you can click on it to listen to the file, delete it or share it through instant messengers.
☑️ Set up call recording
Audio files, especially if you record long conversations in high quality, can take up a significant amount of space, and it is recommended to periodically transfer important records to the cloud or to the computer.
💡
Set up automatic cleaning of old records in the recording settings menu so that the phone’s memory doesn’t overflow unnoticed by you.
Some versions of MIUI allow you to choose between MP3 and WAV formats. MP3 format takes up less space, whereas WAV provides better quality but requires more resources.
Use of third-party applications for recording
If the built-in tools are not available, third-party apps come to the rescue, and Google Play offers a variety of solutions, such as Call Recorder - ACR, Cube ACR or TapeACall, but their performance on modern versions of Android (10, 11, 12 and above) can be limited.
The main problem with third-party software is the lack of access to the system audio stream, which can be recorded through a microphone, which leads to low sound quality and extraneous noises, and the system may require the on- speakerphone to work properly for such applications.
- 📱 Call Recorder - ACR: One of the most popular applications with flexible settings and support for cloud storage.
- 🎙️ Cube ACR: Can record not only ordinary calls, but also conversations in messengers (WhatsApp, Telegram, Viber).
- 📼 TapeACall: Uses a conferencing method to record, which may require payment of operator rates for a second line.
When installing such software, you need to carefully read the permissions they request, often require access to contacts, microphone, phone and storage to work properly, and without all the rights requested, the application can run unstable.
Why have third-party apps stopped working?
Comparison of recording methods on Xiaomi Redmi Note 9
To choose the best option, compare the main characteristics of each method. Staff funds are always preferred, as they are integrated into the system and do not consume batteries. Third-party applications are a fallback when the built-in functionality is not available.
The table below compares the key parameters of the different ways to record conversations on the Redmi Note 9 device.
| Parameter | Staff annex | Third-party annexes | Speaker + Dictaphone |
|---|---|---|---|
| Sound quality | High (digital) | Medium/Low | Low (noise) |
| Automation | Complete. | Depends on the Android version | Absent. |
| Difficulty setting up | Minimum | Medium | Absent. |
| Impact on the battery | Minimum | Average. | High (screen on fire) |
As you can see from the comparison, the built-in capabilities of MIUI are vastly superior to the alternatives. However, if your phone was bought in a restricted region, you have to look for workarounds. Sometimes installing global firmware helps, but it requires technical skills.
💡
Staff recording through the Phone application provides better quality and stability, so you should try to activate it through a change in the region.
Problems with recording and how to solve them
Users may experience a situation where no recording is being made, files are not being saved or the voice of the interlocutor is missing in the file. Often the reason lies in permissions. You need to go to Settings → Applications → Phone → Application Rights and make sure that access to the microphone and memory is allowed.
Another common problem is the overflow of the app's cache. If the phone is slow or the recording functions have stopped responding, try clearing the phone app's cache. This is done through the application management menu in the system settings.
In some cases, the conflict can be caused by the installed themes of design or modification of the system. If you use a third-party theme, try to switch to the standard and check the function. MIUI errors are often corrected.
⚠️ Note: If you use a Bluetooth headset, recording quality may deteriorate or may not be recorded at all, as audio streaming goes through the headset profile rather than through the main module of the phone.
To resolve headset issues, you sometimes need to manually switch the sound source in the recording settings if such an option is available, or temporarily turn off Bluetooth for important conversations.
Legal aspects and ethics of recording
When recording conversations, it is important to keep in mind the laws of your country: in some states, the consent of both parties to the conversation is required for the recording to be legal; in others, the consent of one party (the one who keeps the recording) is sufficient.
The use of the record as evidence in court also has its nuances: the file must be original, without editing, and it must be possible to confirm its authenticity. The digital signature and metadata of the file play an important role here.
Respect for the person's conversation is an important ethical point, and even if the law allows recording, it's a good tone to warn the person that the conversation is being recorded, which helps avoid embarrassing situations and preserves trust.
