Owners of modern Xiaomi smartphones, including the popular Poco X3 Pro, often face intrusive voice alerts when recording a phone call, a feature introduced by the developers of the MIUI shell to comply with data privacy laws in many countries. However, for many users, a constant audible warning “Talk recording” or “Recording begins” becomes a serious irritant, especially if you record important business conversations regularly.
The problem is that standard methods, through the settings menu, completely remove this warning in the latest versions of firmware, it is almost impossible. The system rigidly binds this sound to the voice recorder function in the call. However, there are workarounds that allow you to minimize discomfort or completely drown out this signal. In this article, we will discuss all the available methods, from simple volume settings to more complex manipulations with system files.
It should be noted that turning off the audio notification does not mean that the interlocutor will stop hearing the warning if it is broadcasted to the communication channel, but in most cases it only sounds in the dynamics of your device. It is important to understand the risks associated with changing system parameters, and act carefully so as not to disrupt the main communication module.
Reasons for the appearance of sound notification in MIUI
The Xiaomi and Poco smartphone conversation recording feature is a deep system-wide feature, and voice alerts are a must-have interface that informs all dialogue participants that a conversation is being recorded, a requirement of many countries where consent is a requirement, so MIUI has made it impossible to permanently disable this feature in global firmware versions.
The sound file you hear is stored in the system folder and activated by the start trigger. The volume and presence of the sound may vary from region to region and shell versions. For example, in Indian or European builds, the audio alert may be louder and more persistent than in Chinese versions of the software. Understanding the nature of this sound helps you choose the right method of dealing with it.
⚠️ Warning: Deleting the system files responsible for recording completely can cause the Phone application to malfunction or the recording function to disappear completely.
Poco X3 Pro users often point out that after a system update, sound can appear even when it wasn’t before, because new security patches and Android updates often close loopholes that previously allowed them to ignore the system’s privacy settings.
Basic Volume and Do Not Disturb Mode settings
The easiest and safest way to reduce the volume of an annoying notification is to manipulate the sound profiles, and while you can't completely turn off the system sound through the volume slider, you can minimize the impact on hearing, and you need to change the settings of the media or system sounds just before you start a conversation.
Let’s look at the algorithm for reducing the volume:
- 🔊 Press the volume button and select System Sounds or Multimedia mode, then minimize the slider before calling.
- 🌙 Activate the "Do Not Disturb" mode» (DND), It can suppress some system sounds, although in newer versions. MIUI It doesn't always work.
- 🔇 Use the No Sound feature for all notifications, making the voice alert less contrasting in the background of silence.
This is not ideal, because it requires manual adjustments every time you call, but it doesn't require a super-user right, and it doesn't pose a risk to system stability, and if you need to record one important conversation, it's the most useful way to do it.
💡
Use a physical button to turn off the sound before starting a call if your region allows it through button settings to instantly drown out all system sounds.
Use of third-party applications for recording
An alternative to Xiaomi’s built-in voice recorder is installing third-party apps from the Google Play store, which developers often bypass system limitations or use their own audio capture techniques that do not activate the standard MIUI shell voice warning.
Popular applications for recording conversations:
- 📞 Call Recorder - Cube ACR: One of the most popular solutions that can bypass the limitations of Android 10, 11 and above.
- 🎙️ TapeACall: a paid but reliable app that records a conversation via conferencing.
- 📼 Automatic Call Recorder: a classic solution with flexible settings and cloud storage.
When using third-party software, it is important to consider that the Poco X3 Pro with its Snapdragon 860 processor may experience resource conflicts, and some applications require special permissions through the Android Debug Bridge (ADB) to work correctly, for example, you may need to enable access to special features.
It is worth noting that Google in recent versions of Android actively fights with third-party recording, so the effectiveness of such applications can vary, in some cases, recording can be conducted without the sound of the interlocutor, if not activate the speakerphone.
Advanced Method: Replacing System Audio File
For those who are not afraid to work with the file system, there is a method of replacing the audio notification file with an empty audio file. This method requires the presence of Root rights or the use of special file managers with access to the system partition. On Poco X3 Pro, obtaining superuser rights will unlock the bootloader, which can affect the operation of banking applications.
The file replacement process is as follows:
- Find a file with a name on the Internet call_recording_notification.wav (or similar to your version MIUI), silence.
- With a file manager (such as Root Explorer or MiXplorer), go to /system/media/audio/ui/.
- Back up the original file and replace it with a silence file.
⚠️ Note: Any interference with the system partition /system This can lead to a “boot loop” (cyclic reboot) of a smartphone. be sure to create a full backup of data before starting the procedure.
After replacing the file and restarting the device, Xiaomi will try to play the audio file when recording the conversation, but since it is empty, you will hear silence.This is the most effective method, but it requires technical literacy. Owners of the Poco X3 Pro should also consider that unlocking the bootloader can reset warranties and some security features.

Comparison of methods of switching off sound
To make it easier for you to choose the right option, we have prepared a method comparison table that will help you assess the risks and effectiveness of each method for the Poco X3 Pro.
| Method | Difficulty | Efficiency | Risks. |
|---|---|---|---|
| Volume control | Low. | Medium | Absent. |
| Third-party annexes | Medium | Tall. | Conflicts PO |
| Replacement of the system file | Tall. | Maximum | Tall (Bootloop) |
| Do Not Disturb mode | Low. | Low. | Skipping calls |
As you can see from the table, the safest option for the average user is to use third-party apps or simply adjust the volume, and only experienced users who understand the structure of the Android file system should take drastic measures.
☑️ Check before modification of the system
Impact of MIUI and region on the recording function
It is important to understand that the behavior of the recording function depends on the region set in the smartphone settings. Xiaomi has a strict separation: in some regions (for example, India, Indonesia, EU countries), recording conversations can be completely prohibited or severely restricted, while in others (China, Russia, Ukraine) it is available by default.
Changing the region in settings (Settings → Additional settings → Region) can change the behavior of the system. Sometimes switching the region to Singapore or Indonesia and back can reset some notification settings, although in the latest versions of MIUI 12.5 and MIUI 13/14 this method works less and less.
The key point is that even if you've changed region, the system sound file remains the same unless you've flashed the device, so changing region is a helpful method that's worth trying first, because it's safe.
💡
Changing the region is the safest first step that doesn’t require technical skills, but its effectiveness on newer versions of MIUI firmware is limited.
