Owners of the popular Redmi Note 5 smartphone often face an unexpected limitation: the standard conversation recording feature used in older firmware versions may be missing or not working properly, due to changes in privacy laws and Xiaomi’s move to use the standard Google Dialer instead of its own call app. However, the need to record important agreements, addresses or promises has not gone away, and it is still technically possible to implement this.
There are several effective ways to activate this feature, each of which depends on the specific version of the MIUI operating system installed and the regional settings of your device. In this article, we will discuss in detail the regular system tools, work with engineering codes and install specialized software if the standard paths are blocked by the manufacturer.
Before you start setting up, it's important to understand that recording quality is directly dependent on the microphone and software algorithms for noise reduction. Sometimes, to get pure sound, you need to change the source of the audio in the settings or use a headset. Let's look at the main ways that you can regain control of phone conversations.
Checking the built-in function in the call app
The first step is to make sure that your firmware version has a native feature hidden in it. In some regions, such as India or the European Union, Xiaomi enforces Google Dialer, which by default does not have a write button in the interface. If you have a global or Russian version of MIUI installed without strict regional restrictions, the feature can be simply turned off in the settings.
Open the standard Phone app and find the menu icon, which is usually represented by three dots or a gear in the upper right corner of the screen. Go to Settings and carefully examine the list of options available. If you see Call Record, you are lucky enough to activate the switch and set up automatic recording for all incoming or outgoing calls.
If you don't have one, it's complicated, but it's not critical. It means that at the software level, the function is locked to your region. However, there are workarounds, including changing the region in the system settings or using special codes to activate hidden menus.
- 📱 Open the Phone app and go to settings via the menu.
- ⚙️ Find the Settings section and check for the availability of Call Record.
- 🌍 If there is no item, check the current region in the general settings of the smartphone.
- 🔄 Try changing the region to Singapore or Indonesia to unlock the feature.
💡
Changing the region in the phone settings often returns the native recording feature, but can change the format of the date and time display in some system applications.
Activation through engineering menu and codes
One of the most powerful ways to enable recording on the Redmi Note 5 is to use hidden engineering codes, which allow you to access deep system settings that are not visible to the average user, and in particular, we are interested in the menu related to the VoLTE settings and regional features of the modem.
To access the advanced settings, dial ##86583## in your phone. If successful, you will see a pop-up message “Voice feature check disabled” or “enabled.” Your goal is to get the feature disabled, as paradoxically, this action will unlock the write button in the call interface on many versions of MIUI.
⚠️ Warning: Be extremely careful when entering engineering codes. Changing unknown parameters in other menus (e.g. ##4636##) can cause network signal loss or communication modules to malfunction.
If the first code didn’t work, try the alternative option associated with VoLTE settings: ##86583#. After you enter the code, restart the device and check the settings of the Phone application again. Often after such manipulations, the desired switch appears in the menu.
☑️ Verification of activation of the function
Use of third-party applications for recording
When standard methods are exhausted, third-party developers come to the rescue. Call recording apps use different audio capture algorithms, and the effectiveness of each can vary depending on the Android and MIUI version. The most popular and proven solutions are Cube ACR, Automatic Call Recorder and Blackbox Call Recorder.
When installing such software, the system will ask for a number of permissions, and it is critical to provide access to the microphone, phone and, especially for newer versions of Android, access to "Accessibility" without it, applications will not be able to intercept the audio stream during a conversation.
Note that on Android 10 and above, Google has implemented strict restrictions on recording calls, blocking third-party apps from accessing the audio stream during a call, which can result in recordings that are quiet or without the voice of the interlocutor, in which cases applications often offer to use a hands-free mode or a special service number to bypass restrictions.
- 📥 Download a proven app like Cube ACR Blackbox from Play Market.
- 🛡️ Provide all requested permits, including access to special facilities.
- 🎙️ In the application settings, select the sound source “Voice Call” or “Mic».
- 🧪 Make a test call to check the quality of both interviewees' recordings.
Some applications require an additional component, the App Connector, to be integrated deeper than a regular application, and if after installation, the program says that the component is not active, go to the special features settings and turn on the corresponding item for your recorder.
Configure automatic recording and formats
After the function is successfully activated, whether native or through third-party software, you need to properly configure file storage options. Recording all conversations can quickly fill the internal memory of Redmi Note 5, so it is important to install automatic cleaning of old files or choose to save to the SD memory card.
In the voice recorder settings, select your preferred audio format. MP3 or AAC format provides good quality with a smaller file size compared to WAV. It is also recommended to activate the "Write only contacts" or "Write only certain numbers" function, unless you need to archive every incoming call from unknown numbers.
Where are the records kept?
Pay attention to the notification settings. It's useful to leave an audible warning when recording begins, so you don't forget that the conversation is being recorded, and it's also a requirement of etiquette and law in many countries that the interlocutor should be warned.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Audio format | MP3 or AAC | Saving disk space |
| Sound source | Microphone / Voice Call | Quality of the interviewee's record |
| Storage | SD-card (if any) | Preservation of free space |
| Auto-removal | In 30 days. | Automatic Memory Cleanup |
Sound problems and their solution
The most common problem faced by Xiaomi users is that they record, but they can’t hear the other person, because modern smartphones use different channels to play sound and record, and the noise cancellation system can treat the voice of the interlocutor as background noise and silence it.
To solve this problem, in third-party apps, try switching Audio Source in the settings. Experiment with options: Mic, Voice Call, Camcorder. Different versions of Android and MIUI firmware run different sources, and turning on speakerphone while you're talking can also help, although it's not always convenient.
⚠️ Attention: Using hands-free to improve recording can cause an echo if the microphone captures sound from the speaker.
If you use a headset, make sure the recording app has permission to work with Bluetooth devices. In some cases, recording through the headset gives the cleanest result, since the audio stream is digitally transmitted, bypassing the microphone and speaker of the smartphone.
💡
If you can not hear the interlocutor, changing the source of sound in the settings of the application or turning on the speakerphone is the most effective methods of solving the problem.
Legal aspects and data security
When recording telephone conversations, you should be aware of legal responsibility. In the Russian Federation, recording your own conversation for personal purposes is usually not prohibited if you are one of the interlocutors, but the distribution, publication or transfer to third parties of the recordings without the consent of the second party may violate the right to privacy.
Keep your records secure. If you use cloud services to sync, make sure your account is protected by two-factor authentication. Private conversations can become a serious problem. Periodically check the records folder and delete files that no longer carry information value.
It's also worth remembering that some banking and government agencies warn you about recording a conversation, and in such cases, the recording is already on the organization's side, and it only makes sense to duplicate it for your personal archive.
