Xiaomi smartphone owners often face unexpected software limitations, especially when it comes to basic communication features.The conversation recording feature, which seemed standard for MIUI users over the years, has become less accessible in recent versions of Android.This is due to changes in the operating system security policy that Google has implemented since Android 9 and 10.
You don't have to despair if you don't find a button in the standard phone interface. There are proven ways to activate this option using hidden engineering codes, changing regions, or third-party applications. Understanding how MIUI and Android work will allow you to regain full control of your device. Below, we'll take a look at all the available methods, from the simplest settings to more complex technical solutions.
Standard settings and built-in voice recorder
The first thing anyone needs to do is check the basic settings of the built-in Phone app. In some regions and certain firmware versions, the recording function is still available in the public domain. To do this, open the call app, click on the three dots in the upper right corner and select Settings. Next, look for Call Record. If this section is present, you're lucky that you can set up automatic recording of all incoming or outgoing calls, and select specific contacts.
However, it is often the case that the "Recording of calls" item is either completely missing or not working correctly (recording is without the sound of the interlocutor), in which case the system restricts access to the audio stream for privacy purposes. The built-in recorder can only work in hands-free mode, which is extremely inconvenient in places, and this is where alternative activation methods come to the rescue.
⚠️ Note: In some countries, recording telephone conversations without warning is prohibited by law.
Activation through region shift
One of the most effective and safest ways to return the recording function is to change the region in the settings of the smartphone. Xiaomi developers often restrict the functionality depending on the geographic location specified in the system. For example, in regions with more relaxed legislation or specific requirements (India, Indonesia, some CIS countries), the recording function is built-in by default.
To implement this method, go to Settings → Additional Settings → Region. In the list that opens, select a country other than your current one. It is recommended to try options such as India, Indonesia or Vietnam. After changing the region, the phone interface may change slightly, new widgets or applications will appear, but most importantly, the desired option should appear in the call settings menu. Don’t be afraid to change the region: it does not affect GPS, does not block banking applications and does not require rebooting the device.
If you have a feature after you change your region, you can use it all the time, but remember that changing your region can affect some system services, such as Xiaomi Pay or the recommendations in the Security folder. So once you turn on the record, you can try to return the region back, although often the setting is maintained after you return. Regional restrictions are a software crutch that is easily bypassed by this method.
Use of hidden engineering menu
A more advanced way that doesn't require region change is to use special codes to log into the engineering menu, which allows you to activate hidden modem and telephony functions. However, it doesn't work on all processors and versions of MIUI. This is most often the case for devices based on MediaTek processors, but it's worth trying on Snapdragon.
To get to the menu, open the Phone app and type one of the following codes: ##3646633## or ##4636##. If the code is correct, the Engineer Mode menu will open. You need to find the Telephony or Hardware Testing tab, then go to Audio or Debug. Here you can find settings related to recording audio. Be very careful: changing unknown parameters in this menu can lead to unstable communication.
In some cases, activation is done through code ##888##, which opens a special menu to test the recording. If your phone responds to code input, follow the instructions on the screen. The engineering menu is a powerful tool for service centers, so use it only if you know what you're doing. Wrong frequency settings or audio codecs can make the phone "deaf."
What do I do if the codes don't work?
Set up third-party applications to record
When embedded methods are powerless, third-party applications come to the rescue. Google is actively fighting them, forcing them to use complex workarounds, but developers find solutions. The most popular and stable solutions at the moment are Cube ACR, Automatic Call Recorder and Blackbox Call Recorder.
The way these apps work is often by using special drivers or accessibility modes, and once installed, you'll need to give the app a lot of permissions: microphone, phone, contacts, and critically, special permissions for people with disabilities, which are necessary to intercept the audio stream, bypassing Android's system constraints.
In the settings of the selected application, be sure to turn on Safe Mode or Alternative Recording Method. It may also be necessary to turn off battery optimization for this application so that the system does not "kill" the recording process in the background. Third-party recorders may work less stable than the built-in ones, and sometimes require the on-hand communication for better audio quality of the interlocutor.
Comparison of recording methods
To make it easier for you to choose the right option, we have prepared a comparative table of the main methods, each of which has its pros and cons depending on the model of your smartphone and the version of the operating system.
| Method | Difficulty | Sound quality | Stability |
|---|---|---|---|
| Change of region | Low. | High. | Tall. |
| Engineering menu | Tall. | High. | Medium |
| Third-party annexes | Medium | Medium/Low | Depends on the Android version |
| Speaker + Dictaphone | Low. | Low. | Tall. |
As you can see from the table, changing the region is the most versatile and secure method for most Xiaomi users: it does not require the installation of suspicious software and gives access to the native recording function with high sound quality.
💡
For better recording quality through third-party apps, use headphones with a microphone to help separate audio streams and avoid echoes.
Sound problems and their solution
A common problem with recording conversations on modern Android smartphones is that the voice of the person you're talking to is not there. You hear yourself, but the file is silent or just your voice. This is because modern versions of Android isolate the audio streams of apps from each other.
If you're having this problem, try to turn on speakerphone while you're talking, and then the phone's microphone will capture the speaker's sound, and the recording will be successful, albeit with a loss of quality. And some third-party apps also have a "Sound Source" setting. Try to go through the options: Mic, Voice Call, Voice Communication. Sometimes switching between them helps.
⚠️ WARNING: When using hands-free, make sure you are in a quiet room, otherwise the recording will contain a lot of extraneous noises and echoes.
Where records are stored and how to export them
After successful activation of the function, it is important to know where to look for saved files. In the standard application "Phone" from Xiaomi, records are usually stored along the way: → MIUI → sound_recorder → call_rec. The files are formatted.m4a or.mp3 and are named by the date and time of the call.
You can use a built-in file manager or Dictatoron to manage records easily, and you can sort files by date, and you can add a note to each of them, or you can rename them, and file export is done in the standard way: select the entries you want, click Share, and send them via messenger, mail, or save them to the cloud. Regularly clean the folder with the records, as they can take up a significant amount of memory.
💡
Regular backup of conversation records to the cloud or to the computer will save you from losing important information in the event of a reset or breakage of your smartphone.
