Owners of the budget but functional smartphones of the Redmi line often face the need to document important phone conversations. The Redmi 9 model is equipped with a MIUI shell, which, depending on the version and the region of the firmware, can implement the function of automatic or manual recording of audio when calling. Understanding the mechanics of the system recorder in conjunction with the phone book is the key to solving the problem without installing third-party applications.
The main difficulty is that global firmware versions for Europe and Russia are often based on the Google Phone app, which has strict restrictions on recording conversations for privacy reasons. However, depending on the region chosen in the device settings, the standard call interface can change, opening access to native recording tools. It is important to consider that the laws of different countries dictate the technical capabilities of the software, so a simple change in settings is often preceded by an analysis of the current system configuration.
In this article, we will discuss in detail all the available methods for activating this feature, from standard menu settings to more complex manipulation of system files. You will learn why the write button can disappear after an update and how to return its functionality using the built-in capabilities of the MIUI shell. The correct configuration will allow you to save your communication history directly in the device’s memory, providing quick access to the conversation archive.
Analysis of the interface version and phone application
Before you start activating the function, you need to clearly define which application handles incoming and outgoing calls on your Redmi 9. Modern MIUI builds most often use two options: native MIUI Dialer (Chinese or Indian version) and Google Phone (global version).
If you see a call with a distinctive rounded button interface and a Google logo in the corner, your device is powered by Google Dialer, but it has significant limitations: the caller hears a voice alert to start recording, and the files are stored not in the phone’s memory, but on Google servers accessed through call history, an important nuance for those who plan to store the archive locally.
If you use the native MIUI Dialer, the functionality is much broader, it allows both manual and automatic recording of all incoming and outgoing calls, files are saved in standard MP3 or AAC format directly in the internal memory of the device, you can determine the type of dialer by looking at the icon of the Phone application or by going to its settings through the call menu.
⚠️ Note: When using Google Dialer, both interlocutors hear the recording notification, and it is impossible to disable this audio signal using standard methods, since this is a requirement of Google’s security policy.
For users who are critically interested in stealth or lack of warning phrases, the only option is to switch to alternative methods or change the firmware region if the device model allows, but even with standard functionality, you can optimize the data retention process by correctly configuring sound quality parameters and file storage rules.
Standard activation through the call settings menu
The easiest and safest way to enable audio capture is to use the phone app’s regular settings menu.This method requires no additional software installation and works consistently on most Xiaomi Redmi 9 devices unless the region of the device blocks this option. First, open the Phone app and look for the gear icon or three dots in the upper right corner of the screen.
In the menu that opens, select Call Recording, where you will see a control panel that allows you to activate the Automatic Call Record switch, and if this is not available, your current region in the system settings (Settings → Advanced Settings → Region) does not support this feature, and you will need to change the country to one where recording is allowed by law, for example, India, Vietnam or Kazakhstan.
Once activated, the system will prompt you to choose the rules: write down all numbers, only unknown or only favorite contacts, this saves space in memory and does not record advertising Calls. Also in this menu, you can choose the option “Warn about recording”, which in the native MIUI Dialer can be turned off, unlike Google Dialer, where it is forced.
☑️ Checking the recording settings
It is also important to pay attention to the format of saving. In some versions of MIUI, you can choose between MP3 and AAC. AAC format provides better sound quality with a smaller file size, which is true for Redmi 9 with its limited internal memory in the basic configurations.
Set up automatic recording for specific contacts
The MIUI shell feature allows you to flexibly manage the recording process by highlighting individual numbers in a priority group, which is especially useful if you are expecting an important call from a client or partner and do not want to risk relying on manually turning on a recorder during a conversation.
To assign an automatic record to a particular subscriber, open the Contacts app, select the personal card you want, and find the Call Record (if it's not visible right away, press "More" or three dots) and you can set the switch to the "Automatically Write" position, and then all the dialogs with that number will be saved without you.
An alternative way is through call history, click on the information icon (i) next to the number in the call log, then select the entry option. The system can suggest creating a rule for that number, which is convenient because it does not require deep immersion in the system settings and works on the fly.
- 📞 Open your contact card in the Redmi 9 phone book.
- ⚙️ Find the “Call Record” section in the Action menu.
- ✅ Activate the automatic recorder for this number.
- 🔔 If necessary, set up a notification to start recording.
Remember, when you write automatically for specific numbers, the file is created immediately after the connection. If the call is reset before the answer or during the beeps, the file may not be created or empty. The system logger only records the connection that is installed, so it is important to wait for the subscriber's response before starting an important conversation if you rely on automation.

Google Dialer Problems and How to Solve Them
Redmi 9 users with global firmware (Global) ROM) Often, they face a situation where the usual recording button disappears or starts to work with restrictions, due to Xiaomi’s transition to Google Phone standards in the EEA. In this case, the staff recording becomes impossible without the use of third-party solutions or complex manipulations with system systems. APK-file.
One of the methods that works, but doesn't guarantee 100% results, is to clean up the phone and contact data after changing the region. Sometimes the old configuration cache blocks new menu items from appearing. To do this, go to Settings → Apps → All apps, find Phone, click Clear and select Clear All. After rebooting, check the settings again.
If standard methods don’t work, you can try installing a modified version of Google Phone or returning the old one.

It’s important to understand that with Android 10 and up, Google has closed direct access to the audio stream to third-party apps, which means that many of the Play Market’s apps either record silence or require hands-free, which reduces audio quality, so the native MIUI Dialer remains the preferred option for those who care about functionality.
Use of third-party applications for recording
In situations where Redmi 9’s system limitations don’t allow you to turn on the recording in the desired way, specialized applications from the Google Play store come to the rescue.The leaders in this niche are SKVALEX’s Call Recorder, Cube ACR, and Automatic Call Recorder. These programs use various workarounds to capture sound, including the use of special drivers or accessibility modes.
When installing such software, you need to provide advanced permissions, including access to a microphone, phone and, in some cases, access rights to "Accessibility" (Special features), which is necessary for the application to automatically press the virtual recording button when an incoming call is made. Configuring such programs takes time: you need to find the right audio source so that the interlocutor is heard clearly, rather than through the speaker's echo.
However, it is worth considering that on Android 11 and later, which are available for Redmi 9, the effectiveness of such applications is reduced, they may require the turn on of hands-free communication or work unstable after Google security updates.
- 📲 Download a proven recording application (e.g. Cube) ACR).
- 🛠 All permissions requested, including access to contacts.
- 🎚 In the application settings, select the sound source “Voice Call” or “Mic».
- 🧪 Make a test call to check the quality and volume.
Some advanced users use helper apps that emulate screen taps by activating the built-in MIUI voice recorder if hidden but accessible via ADB. This is a complex method that requires a PC connection, but it allows you to keep native sound quality and integration with the system.
Search and manage saved files
After the successful activation of the function, the question arises of organizing the stored material. 9 Default records get into the folder MIUI/sound_recorder/call_rec. You can find them through the standard Files Explorer in the Audio or Records section. For convenience, it is recommended to periodically sort files or transfer them to the cloud storage so as not to overflow the internal memory of the device.
Files have a convenient naming system: usually it is the date, time and phone number (or contact name, if it is saved in the phone book), which allows you to quickly find the desired conversation through a file search. If you use Google Phone, you can find the record by opening the call history, selecting the desired number and clicking on the speaker or microphone icon in the details of the call.
⚠️ Note: When you reset your phone to a factory setting, all local records will be permanently deleted. It is recommended to regularly back up important conversations to your computer or to the Mi Cloud / Google Drive cloud service.
To listen to the recordings on your computer, just plug your smartphone into a USB and copy files. They play back with any standard media player. If you have a problem that the files are not opened or have a strange format, try renaming the extension to.mp3 or using a universal player like VLC, which reads most audio codecs.

Use the Favorites feature in the Dictophone app or file manager to flag important conversations that can’t be lost while cleaning your memory.
