Xiaomi and Redmi smartphone owners often encounter an intrusive beep during a conversation that informs the interlocutor about the start of recording. For the Redmi Note 8 Pro, this issue has become especially acute after the updates to the MIUI shell to versions 12 and 13, when the company tightened its privacy policy.
The nature of this phenomenon is in the laws of different countries, which require that all participants in a conversation be notified of the recording of the audio stream, the system restriction is implemented at the firmware level and does not have a standard switch button in the settings menu, but there are workarounds that allow you to modify the behavior of the system.
In this article, we will discuss in detail the technical aspects of the call recorder, assess the risks of interfering with system files and propose current methods for solving the problem. It is important to understand that any changes in system settings require carefulness and accurate follow-up to instructions.
Reasons for the appearance of sound notification in MIUI
The appearance of a loud “Recording started” signal or a characteristic squeak every 15-20 seconds due to changes in Google’s policy and local laws on the protection of personal data. Beginning with certain versions of Android (particularly Android 9 and higher), access to the microphone during the call for third-party applications was limited, and the system recorder received a mandatory notification requirement.
In the Redmi Note 8 Pro, which runs MIUI Global, this feature is tightly tied to the region. If the phone settings indicate a region where recording conversations without notice is prohibited by law, the system automatically activates the beep, which is not a bug, but a legal requirement that Xiaomi must comply with to enter international markets.
⚠️ Note: Changing regional settings may affect the performance of some localized services, such as news feeds or weather widgets.
It is also worth considering that different versions of firmware (Chinese, Global, Indonesian, Indian) have different codes of behavior for the telephony module. In Chinese versions (CN ROM) often there are no warnings, whereas in global (Global ROM) they are present by default.
Change of region in smartphone settings
The simplest and most secure method, which does not require root rights or a computer connection, is to change the geographic region of the device, and the logic is simple: if the phone “thinks” it is in a country with liberal laws regarding recording conversations (for example, Singapore, India or China), then the audible warning may not activate.
To do this, you need to go to the settings menu, find the "More" section, and select the "Region" section, and experiment with different countries, and most Redmi Note 8 Pro users notice the signal disappearing when choosing the "India" or "Singapore" region.
Once the region changes, the system may need to reboot or simply apply changes instantly. Check the recording by making a test call. If the sound is gone, the problem is solved. However, it is worth remembering that changing the region can change the set of pre-installed applications and the theme of the design.
💡
After changing the region, restart your phone to make sure that the changes in system configurations are applied correctly.
Use of engineering menus and codes
More advanced users can access hidden settings through an engineering menu, which is an interface for diagnosing and testing hardware components, but in some versions. MIUI You can find the parameters that affect the audio stream. USSD-code entered in the appendix “Phone».
The most common code to log into the engineering menu is ##6484## or ##3646633#. Once you enter the combination, the test list will open. You need to find the section associated with Audio or Telephony. However, on newer versions of Android, access to changing recording settings through this menu is often closed.
There is also a code ##8255## that runs the GTalk Service Monitor, but it is rarely useful for this task.
| Team team. | Function | Efficiency for Redmi Note 8 Pro |
|---|---|---|
| ##4636## | Testing menu (phone information) | Low (no sound settings) |
| ##6484## | CIT (Equipment Testing) | Medium (access to audio tests) |
| ##3646633## | Engineer Mode (Engineering Menu) | High (for experienced users) |
| ##8255## | Gtalk Service Monitor | Low (outdated service) |
Be careful when changing the parameters in the engineering menu. Incorrect setting of frequencies or audio codecs can cause the microphone to stop working correctly or there will be extraneous noises.
Application of ADB commands to disable the signal
The most reliable software method that does not require root rights is the use of USB debugging and the ADB tool (Android Debug Bridge), which allows you to send commands directly to the system, changing hidden global settings that are not available through the normal interface.
First, you need to activate the developer mode. Go to Settings → About Phone and quickly click on the build number (MIUI Version) 7 times. After that, a new section for developers will appear in the menu. Inside you need to include the item "Debugging by USB".
☑️ Preparation for use ADB
Once you connect your smartphone to your computer and install the ADB, open the command line or terminal. You will need to enter a command to change the global variable responsible for recording. The command that is often used is as follows:
adb shell settings put global call_recording_enabled 1However, depending on the version of MIUI on the Redmi Note 8 Pro, the variable may be called differently. Sometimes you need to change the settings in the phone's app settings database. If the standard commands don't work, it means that your firmware version will hard-wire that setting.
⚠️ Attention: Use ADB Incorrect commands can cause unstable system operation or resetting of settings.
There is also a method using specialized ADB-Applets like Xiaomi ADB/Fastboot Tools: These programs have a graphical interface and allow you to safely remove system applications or change hidden flags associated with regional restrictions.
Third-party applications for recording conversations
If the warning fails to be removed by system methods, you can resort to third-party software. However, Google's Android 10, 11 and above policy severely limits the ability to record conversations with third-party applications. Most programs from the Play Market either do not work or record silence instead of the voice of the interlocutor.
However, there are applications that use special Accessibility APIs to emulate clicks or capture audio in another way, such as Call Recorder - SKVALEX or TapeACall, which may require payment or subscription for full functionality.
How do bypass applications work?
Many Redmi Note 8 Pro users note that when using third-party recorders, the warning sound may still be present, as it is generated by the telephony itself, not the recording application, in which case only flashing the phone to a version from another region helps.
Reflashing to Indian or Chinese version of MIUI
The radical but most effective solution is to completely reflash the device to a version of software where recording conversations is allowed by default without warning. For the Redmi Note 8 Pro (codenamed ginkgo), Indian (IN) and Chinese (CN) firmware are popular.
The Indian firmware (MIUI India) is almost identical to the global one, but is free of many restrictions related to call recording and advertising. The Chinese version (MIUI China) has maximum functionality, but may not contain Google services out of the box (they need to be reinstalled) and have problems with LTE frequencies in some regions.
The flashing process requires unlocking the bootloader, which takes 7 to 168 hours to wait, and when unlocked through the Mi Flash Tool, the desired system image is installed, a complex process that requires data backup.
💡
Reflashing to the Indian version of MIUI is the only guaranteed way to remove the warning forever without the use of sophisticated technical means.
Make sure to back up your contacts, photos and important documents before starting the procedure, and there is also a risk of turning your phone into a brick if you break firmware technology.
