Xiaomi smartphone owners often face the need to document important phone calls. Redmi 9, despite its popularity and availability, has features in software that can hide the standard functions of the recorder. Depending on the firmware version (Global, EEA or CN), the call interface can vary significantly, which causes questions when users try to activate the record.
Modern versions of the MIUI shell and the new HyperOS strictly follow the laws on the protection of personal data, so in some regions the automatic recording function may be hidden or absent by default. However, there are proven methods of activating this tool, including the use of built-in system capabilities and third-party applications. In this article, we will discuss all the available ways so that you can be sure of the safety of important information.
Before you go to technical manipulations, it is worth understanding that the quality of the recording depends not only on the settings of the software, but also on the operation of the microphones Xiaomi Redmi 9. The correct configuration allows you to record not only the voice of the interlocutor, but also your own without echo and extraneous noises. We will consider the nuances of the operation of the audio system of the smartphone in conversation mode.
Built-in MIUI telephony capabilities
The standard Phone app in the MIUI shell has powerful functionality that often goes unnoticed. In most cases, for Redmi 9 with global firmware, the recording function is natively built in, but hidden in the depths of the settings menu. To activate it, you need to open the call app and find the gear icon or three dots in the top corner of the screen. Going to Settings → Call recording opens access to control of this option.
Once activated, the "Record Calls Automatically" switch will start saving all incoming and outgoing connections to a special audio file.

When you turn on a Redmi 9 call recording, you may hear a characteristic beep or see a notification on the screen warning you to record it, depending on the Android version and regional security settings.
If you don’t find Call Recording on the menu, it may mean that your firmware version has regional restrictions.In the European Union and some other regions, Google and smartphone manufacturers are required to restrict recording functionality without the explicit consent of both parties.In this case, the standard path App Phone → Settings → Call Recording may not contain the necessary switches, and you will need to use alternative methods.
Set up automatic recording and filters
Flexible settings allow you to customize your smartphone to your personal needs. In the recording settings menu, you can choose the source of the sound. For Redmi 9, the best choice is Microphone mode, which records sound through the main microphone, or Voice Call, if VoIP capture is supported.

Solving the problem of not having a recording function
The situation when the settings menu does not have a record point is common for global firmware versions.This is due to Google's policy, which in the latest versions of Android (10, 11, 12 and above) restricts the access of applications to the audio stream during a call. For owners of Xiaomi Redmi 9, this means that the standard call can be replaced by Google Dialer, where the recording functionality is limited or requires notification of the interlocutor.
There are several ways to get around this limitation. The first way is to change the region of the smartphone. Go to Settings → Advanced Settings → Region and selecting a country where recording is allowed (for example, India, Indonesia or Singapore) can unlock hidden features. Once you change region, the phone may require a reboot, and the necessary functionality will appear in the call app.
⚠️ Note: Changes in region may affect some system applications, widgets, and system update rates.It is not recommended to use a region other than your actual location continuously unless required to activate specific features.
If changing the region didn’t help, you can try to clear the phone app data. Go to Settings → Apps → All Apps → Phone → Clear the data. This action will reset the call settings to factory, but it won’t delete your contacts or call history. After resetting the first time you start a call, the system can suggest choosing your preferred settings, where you should carefully check the available options.
Use of third-party applications for recording
When Redmi 9’s built-in tools fail or are blocked by the manufacturer, third-party solutions come to the rescue from the Google Play store. Apps like Cube ACR, Automatic Call Recorder or Call Recorder – ACR use various methods of intercepting audio streams. However, due to Android’s limitations, they may require additional permissions or the inclusion of special features (Accessibility) to work correctly.
When installing a third-party recorder on Xiaomi, it is important to properly configure the permissions. MIUI aggressively manages power consumption and can kill background processes to keep the application running--
Or, it's necessary:
- 🔹 In the application settings allow "Auto-run».
- 🔹 In the section "Battery and performance" select "Without restrictions».
- 🔹 Fix the application in memory (lock in the menu of open applications).
- 🔹 Allow access to microphone, phone and storage.
Why can third-party applications not work?
Some applications offer a personal call recording server that bypasses OS restrictions but requires a stable internet connection, depending on the speed of the connection. Before choosing a paid solution, be sure to test the free version to make sure it is compatible with your model and Android version.
Table of comparison of recording methods

|---|---|---|---|
| Built-in MIUI function | High (digital flow) | Low. | Absent. |
| Change of region | High. | Medium | Minimum |
| Third-party annexes | Medium/Low (microphone) | Tall. | Depends on Android. |
| Speaker + Dictaphone | Low (noise, echo) | Low. | Absent. |
As you can see from the table, a native function or region change is the best. Using a speakerphone with a speakerphone on is the last resort when other methods are not available, but the quality of such audio often leaves much to be desired due to the intrusion of extraneous noises in the room.
