Owners of Xiaomi, Redmi and POCO smartphones often face an annoying situation: when activating the call recording function, the interlocutor hears a loud system message, a standard security measure implemented by the developers of the MIUI shell and the new HyperOS to comply with personal data protection laws. However, for many users, this becomes a serious problem, especially if business negotiations are conducted or important agreements with customers are recorded.
Unfortunately, it's almost impossible to remove this notification completely in the global firmware versions without using third-party solutions or changing the region, and the system is rigidly programmed to inform all participants in the dialogue, but there are workarounds that minimize discomfort or change the behavior of the device at the time of recording the audio.
In this article, we will discuss all the known ways to solve this problem, from simple settings on the menu to more complex manipulation of system files. You will learn why the warning appears, how to change the region to access hidden functions, and what applications can help in automating the process. It is important to understand that each method has its own nuances and is applicable to certain versions of the operating system.
Reasons for the appearance of voice notification
The main reason for the loud voice to announce the start of a recording is due to legal requirements in various countries, where companies like Xiaomi are required to comply with local privacy laws, which state that recording a conversation is impossible without the consent of all participants, which is why the phone's software code compulsorily plays the audio message as soon as the recording begins.
Global ROMs are tightly tied to the region they are in, and if you are in a country with strict telecommunications laws, the system will automatically activate the alert, while in some Asian regions where laws are less stringent or non-existent, the feature may work in the background without alerting.
⚠️ Warning: Attempting to circumvent system restrictions by modifying system files may cause the phone to malfunction or breach warranty conditions.
It’s also worth noting that with the release of new versions of Android (starting with version 10), Google has significantly restricted third-party apps’ access to the microphone during a call, which is designed to protect users from spyware, which is why even third-party recorders often cannot record a conversation without system intervention or special access rights.
Change of region in smartphone settings
One of the most popular and relatively safe ways to try to get rid of voice alerts is to change the region in your device settings, and the logic is simple: in some countries, recording conversations is regulated differently, and the code for those regions does not contain a command to play the audio file with the warning.
To do this, you need to go to the settings menu and find the appropriate section, which is usually at the top of the list of basic parameters. After changing the region, the phone may need to reboot or simply apply changes instantly by changing the set of preinstalled applications and services.
The most effective regions for disabling notifications are:
- 🇮🇳 India – often allows recording without loud warnings, but can change the set of standard applications.
- 🇮🇩 Indonesia is another popular option that users often use to access additional features of the theme.
- 🇸🇬 Singapore – sometimes helps change the behavior of the system dialer (call callers).
It's important to understand that changing regions doesn't just affect call recording, you can have weather services, news feeds, and even some system applications appear or disappear, for example, when you select India, you can have Mi Video on your desktop with content for that market.
💡
After changing your region, be sure to check the other features: NFC, Google Pay (if relevant), and contact sync to make sure that important services are working correctly.
Instructions for changing the region: step-by-step algorithm
The process of changing the geographic location of the device does not require root rights or a connection to the computer. All actions are performed directly through the operating system interface. Below is a detailed algorithm that will help you perform the configuration correctly.
First, unlock your smartphone screen and find the Settings icon. It usually looks like a gear and is located on the home screen or in the notification curtain. In the menu that opens, scroll through the list to Additional Settings (or Advanced Settings). In some versions of HyperOS, this item may be simply called “About Phone” or be displayed on a separate menu.
☑️ Algorithm of region change
Next, perform the following actions:
- In the list of countries that opens, select, for example, India or Indonesia.
If the notification is gone after the region change, you have reached your goal, but if the voice support is left, it means that your firmware version has blocked or does not work for the current carrier, in which case it will not take long to return the region back.
Use of third-party applications for recording
The regular call from Xiaomi and Google has strict restrictions, imposed by the operating system. However, there are specialized applications that try to circumvent these restrictions using different methods of capturing the audio stream, they can use screen availability, voice dialing or special accessibility services (Accessibility Services).
One of the most famous solutions is the Call Recorder app - Cube. ACR. It can record not only the usual GSM-calls, but also conversations through messengers such as WhatsApp, Telegram and Viber. for proper operation it requires extended permissions, which must be issued manually in the settings of the system.
| Annex | Type of record | Needs a Root-Right. | It works on Android 12+. |
|---|---|---|---|
| Cube ACR | VoIP / GSM | No (preferably) | Partially. |
| TacX | GSM | No. | Yes. |
| Automatic Call Recorder | GSM | No. | Depends on the phone. |
| Blackbox Call Recorder | GSM | No. | Yes. |
It should be noted that on modern versions of Android (11, 12, 13, 14), the effectiveness of third-party recorders is significantly reduced, the system can only record your voice, and the voice of the interlocutor will be barely audible or absent at all, this is due to the fact that the OS blocks access to the incoming audio channel during a call for third-party software.
Why did third-party apps stop working perfectly?
Modification of system files and ADB
For advanced users who are not afraid of the command line, there is a method to disable notifications via ADB (Android Debug Bridge), which allows you to delete or freeze the system components responsible for playing sound warning files, but it requires a connection to the computer and enable debugging over USB.
The first step is to activate the developer mode. → About phone and quickly press 7 times on the item Version MIUI (or OS). After that, a new section Advanced settings will appear in the settings menu → For developers, you need to activate the Debugging by USB.
Once you connect your phone to your PC, open the command line and type in a command to find the package that handles the interface sounds. Often it can be a package associated with a framework-res or a specific sound engine. Deleting or renaming an audio file inside the system partition can lead to the desired result, but requires knowing the exact path to the file.
adb shell pm list packages | grep sound
adb pull /system/media/audio/ui/record_start.ogg⚠️ Attention: Interference in the system partition /system or /vendor Without an unlocked bootloader and superuser rights, you can't do it on modern devices. Trying to do it on a locked bootloader will only lead to an access error.
A safer option through ADB is to revoke permissions from the system application Record Calls or System Sounds, but this can disrupt other audio functions of the phone, so this method is recommended only for experienced enthusiasts who understand the risks.
Frequent questions and problems when setting up
Even following the instructions, users may encounter a variety of challenges: Security updates close old holes, and new phone models have a redesigned architecture. Below, we’ll look at the most common questions that arise when trying to disable intrusive notifications.
Often users ask if the processor model affects the ability to record, in fact, the Android version and the type of firmware (Chinese or global) play a key role. On the Chinese version (China ROM), call recording is often built-in natively and works without warning, as local law allows it.
💡
Global firmware will always have stricter privacy restrictions than the Chinese version of the same phone.
Another problem is the system update, and once you get the OTA update, all your settings can go wrong, and the region can go back to the original value, and then you have to repeat the procedure again, and antivirus built-in scanners can block the installation of modified applications for recording.
