Owners of Xiaomi, Redmi and POCO smartphones often face the need to capture important conversations, whether it’s clarifying order details, a business conversation or talking with tech support. However, after updating the MIUI shell and switching to HyperOS, and because of changes in Google’s privacy policy, the standard feature may be hidden or not work correctly depending on the region of the firmware, which is puzzling for users accustomed to the simplicity of the interface.
In this article, we will discuss in detail all the ways to activate automatic recording, configure exceptions and solve typical problems when the recording button disappears during a conversation. You will learn how to circumvent regional restrictions without obtaining root rights and which Google Play applications actually work on modern versions of Android.
To make matters worse, Google has implemented tough restrictions on accessing the microphone during a call for third-party apps in recent versions of Android 13 and Android 14, which means that old, proven methods may stop working, requiring deeper immersion in system settings or the use of specific regional firmware.
Built-in recording function in MIUI and HyperOS
The standard audio capture mechanism in the MIUI shell and the new HyperOS is the most stable and energy-efficient solution, integrated directly into the Google Dialer or MIUI Dialer system phone, avoiding access rights conflicts, but it depends on the region chosen when you initially set up your smartphone or upgrade your system.
To check for and activate the feature, go to the Phone app and click on the three dots in the top right corner of the screen. In the menu that opens, select Settings, and then find the Call Record section. If this section is present, you are lucky: the functionality is fully available for use without additional manipulation.
Inside the recording settings menu, you can flexibly manage the process, and you can enable automatic recording for all incoming and outgoing, and you can create exception lists, so you can, for example, record only conversations from unknown numbers, or you can ignore contacts from the phone book.
It is important to note that the recording quality of the system application is usually higher than that of third-party counterparts, since the sound is written directly from the digital stream, rather than through the microphone, which eliminates extraneous noise and makes the interlocutor’s speech clear and legible even when the communication is poor.
The Problem of Lack of Function in Global Firmware
Many users are faced with a situation where, after updating or buying a new device, the “Recording of calls” item is simply not in the phone settings menu. ROM), Destined for Europe and Russia, recording features are often cut out due to strict privacy laws. GDPR and Google requirements.
Chinese firmware versions (CN ROM) and some regional builds (such as India or Vietnam at certain times) often contain this feature by default. Global users are forced to look for workarounds, as a simple change of region in the settings (Settings → Advanced Settings → Region) in the latest versions of MIUI 14 and HyperOS stopped returning the missing feature.
⚠️ Warning: Attempts to change the region of the system to China to activate the feature can lead to widgets not working properly, changing the format of the date and time, and advertising in system applications.
It is believed that the installation of the region "India" or "Vietnam" helps to return the menu of the record. MIUI 11-12 It worked flawlessly, and now it's a low success rate. IMEI-a device tied to a specific market.
💡
If changing the region didn’t help, try clearing the phone and contact data from the Apps → All Apps → Find the app → Clean → Clear everything. This will reset the settings cache, but it won’t delete your contacts.
Change of region and special activation codes
Despite the complexity of the procedure, the method of changing the region remains the first thing to try before installing third-party software. The logic is simple: the system loads the configuration files corresponding to the selected country, and if the firmware code contains the ability to write for this region, the function can appear.
The algorithm of actions is as follows:
- 🌍 Open your smartphone settings and go to the Advanced Settings section.
- 📍 Find the Region and select from the list India, Vietnam or China.
- 📞 Restart the device and check the call settings menu.
- 🔍 If no option is available, try dialer code #86583## (for some models, this includes a function).
Entering secret codes is another way to activate hidden functions. Code ##86583# (or variation #865637# to disable region check) can force the recording ability to be enabled. If you successfully enter, you will see a pop-up notification "Voice recorder region check disabled."
Do the codes on HyperOS work?
Note that once activated through codes or region change, the recording notification ("Recording enabled") can sound very loud and full-screen, and in some firmware, you can turn this off in the same recording settings by unchecking the "Vote alert" box.
Third-party applications for recording conversations
If system methods don't work, third-party apps come to the rescue. However, starting with Android 9 and especially Android 11-14, Google shut down the API for recording calls, which led to most apps in the Play Market either not working or forced to turn on speakerphone to record a conversationalist through a microphone.
One of the few exceptions that continues to work on many Xiaomi devices is the Cube ACR app. It uses Accessibility Service to intercept the audio stream. To work properly, you must provide the application with all the requested permissions, including access to the microphone, phone and contacts.
Another popular solution is Appliqato's Automatic Call Recorder. The app has flexible settings and supports VoIP (Viber, WhatsApp, Telegram), which is relevant for modern instant messengers. However, the quality of recording via VoIP can vary depending on the version of Android.
| Annex | Working without a speakerphone | Support for messengers | Advertising |
|---|---|---|---|
| Cube ACR | Yes (via App Connector) | Yes. | It's in the Free version. |
| Call Recorder - ACR | Partially (depends on Android) | Yes. | There is. |
| TapeACall | No (conference call) | No. | Paid subscription |
| Blackbox Call Recorder | Yes (requires settings) | Limitedly. | There is. |
⚠️ Warning: Third-party recorders may conflict with the system call, causing the call to reset or the sound to disappear.If you notice the phone's unstable operation, uninstall the newly installed recording app.
Configure automatic recording and formats
The right setup of the recording settings saves memory space and keeps the conversation archive in order. In the system application and advanced third-party recorders, you can choose the save format, the most common formats are MP3 and AMR.
AMR takes up significantly less space and is optimized for speech, but may play worse on some PCs without installing codecs. MP3 format is more versatile, but files weigh more. For long-term storage of important conversations, it is recommended to choose MP3 with a bitrate of at least 128 kbit / s.
☑️ Checklist for recording setup
You also need to pay attention to the way you save files. By default, records are stored in a folder. MIUI/sound_recorder/call_rec or Recordings/call_rec. It is recommended to periodically transfer important files to the cloud (Google Drive, Yandex.Disk) or to your computer, since when resetting your phone settings or flashing local data will be lost.
💡
Automatically recording all calls is a convenient but resource-intensive process, and regularly check the memory capacity to ensure that you don’t miss an important conversation because of space constraints.
Where to find and how to manage saved files
Once a conversation is over, the file is instantly stored in the device's memory, and you can find it in a number of ways, the easiest way is to open the Dictophone or Call Record app (depending on the version of MIUI), where all files are sorted by date and contacts.
To access through the file manager, you need to go to the internal memory and find the folder. MIUI, later sound_recorder and call_rec. In the new versions of HyperOS, the path may change to Android/data/com.android.phone/files/Recordings, but access to the folder Android/data In the latest versions of Android is limited, so it is easier to use the built-in conductor.
File management allows you to perform basic operations: renaming, deleting, sending via messengers. If you use a third-party application, the files can lie in a separate folder with the name of the program, for example, CallRecorder.
Solving Frequent Problems and Errors
Users often complain that the recording is on, but the voice is not heard. This is a classic Android problem. If the system recording is not working and the third-party recording is only writing your voice, try to turn on the speaker while you're talking, which often helps the microphone catch the person.
Another problem is that there is no record notification, and in some regions (like India) you have to legally alert your interlocutor, if you're in another region, but the region of the phone is India, you'll have to make a loud notification, and changing the region to Russia or Ukraine in the settings sometimes removes the voice alert, but it can hide the function.
⚠️ Warning: Remember the laws of your country, recording a conversation without warning may be illegal.
If the recording is interrupted by itself, check the power saving settings. MIUI aggressively kills background processes. Go to Settings → Battery and Performance, find a recording app, and select No Limits mode. This will prevent the system from unloading the recorder from memory.
