Xiaomi and Redmi smartphone owners often face an unexpected problem: a standard voice recorder feature that has been available for years suddenly disappears or stops working after a system update.This is due to Google’s tightening privacy policy, which requires explicit notification of the interlocutor when recording begins.
There are several effective ways to do this, from simple menu settings to installing specialized software, and in this article we will discuss all the current ways to set up automatic call recording on current versions of the MIUI and HyperOS shell, as well as workarounds for models where this feature was software blocked by the manufacturer.
It’s important to understand that methods can vary depending on the regional firmware (Global, China, EEA) and Android version, and we’ve prepared a one-stop guide to help you keep control of your phone calls regardless of your device model.
The standard capabilities of the MIUI and HyperOS system
The first thing to do before looking for third-party solutions is to carefully check the phone's standard settings. In most cases, the recording function is built into the system call, but hidden from the user's eyes by default. The interface may vary slightly depending on the version of the shell, but the logic remains the same.
To access the settings, open the Phone app and click on the three dots or gears in the corner of the screen. You need to find the "Call Record" item. If there is one, you're lucky that the system doesn't block this feature at the regional limit level, so you can activate automatic recording for all numbers or only for selected contacts.
Within the recording settings menu, note the ability to select audio format and file storage location. By default, the recordings are stored in the device's memory, but they can be redirected to the device. SD-card, if the smartphone model supports memory expansion, this is especially true for users who are in long negotiations.
⚠️ Note: When you turn on a regular record, the phone can play a loud beep or voice notification "Recording has begun" that your interlocutor hears. This is a security requirement that cannot be turned off in a standard call without root rights.
If you don't find "Record Calls" on the menu, it means your firmware is in a region where recording conversations is prohibited by law or restricted by Google's policy, then move on to the next section where we'll look at ways to circumvent this restriction.
Changing the region to activate hidden functions
One of the easiest and safest ways to return the record button is to change the region in the settings of the smartphone. Xiaomi firmware functionality often depends on the location chosen. For example, in regions with less stringent telecommunications laws (India, Singapore, some CIS countries), the recording function is built-in by default.
To use this method, go to Settings → Additional settings → Region. Select from the list the country where recording conversations is allowed. After changing the region, restart the device and check again the settings of the Phone application. Often the desired item appears instantly.
But this method has its nuances: changing the region can affect the performance of some services, for example, change the set of available themes in the theme store or display news in the browser. In addition, on some global firmware (Global ROM), even changing the region does not activate the record, because the restriction is stitched deep in the system.
💡
Once you activate the write function through region change, you can return the region back to Russia or your current one. 90% of the time, the record function remains available because it has already been activated in the system configuration.
It’s also worth noting that this method doesn’t work on European firmware (EEA) devices, where the restrictions are embedded at a deeper level. If changing the region hasn’t helped, don’t despair – there are more powerful tools available to solve the problem.
Use of third-party recorder applications
If the standard methods to enable recording failed, to help come applications from third-party developers. Google actively fights them by blocking access to the audio stream, but some programs have learned to bypass these restrictions using special accessibility services (Accessibility Service).
One of the most popular and effective solutions is the Call Recorder app - Cube ACR. It can record not only ordinary calls through the cellular network, but also conversations through messengers (WhatsApp, Telegram, Viber).
After installing the app, follow the instructions on the screen, you will need to give access to the microphone, phone and, most importantly, enable a special plugin in the special features settings. Without this step, the application will only record your voice or silence.
- 📱 Cube ACR — market leader, supports VoIP recording and has flexible settings.
- 🎙️ Automatic Call Recorder is a simple application with a minimalist interface and cloud synchronization.
- 🔊 Blackbox Call Recorder – Frequently updated to bypass new Android locks.
- 🛡️ Tacx – uses the recording method through the speaker, which guarantees the audibility of both interlocutors.
It’s important to understand that no third-party app gives 100% guarantee of work on all devices.The effectiveness depends on the specific CPU model and Android version.If one app fails, try another from the list.

Table of compatibility of recording methods
For ease of choice, we have compiled a summary table to help determine the best way to write for your situation. Please note that the effectiveness of methods can vary depending on the specific version of the security update.
| Method | Difficulty | Sound quality | Notification of the interlocutor |
|---|---|---|---|
| Staffing | Low. | Excellent. | Got it (voice/signal) |
| Change of region | Low. | Excellent. | Got it (voice/signal) |
| Cube ACR (standard) | Medium | Good. | No (quiet recording) |
| Recording through a speaker | Tall. | Medium (there's an echo) | No. |
As you can see from the table, standard methods provide the best quality of digital audio, but they give the presence of recording. Third-party applications allow recording to be secretive, but the quality can suffer due to the peculiarities of the microphone in hands-free or software processing.
Solving quality and lack of sound problems
A common problem with users is that they're recording, but they're not listening, or they're interrupted, because Android controls audio, and recorder apps may not be able to switch between channels or be blocked by power saving.
To improve the situation, you need to exclude the recording application from battery optimization. Go to Settings → Applications → All applications, find your recorder, select Battery and set No Limits mode. This will prevent the MIUI background services from forcing the recording process to stop.
Also try changing the source of the sound in the settings of the app itself. If you have Microphone, try to switch to Voice Call or vice versa. On some models, Xiaomi helps turn on the hands-free mode during a conversation, although this is not always convenient.
⚠️ Note: On Android 11, 12, 13 and above, the system can force the recording of internal audio streams. If you only hear yourself, this is a system restriction that only costs you to record sound through the microphone (from speakers), which reduces the quality of the audio stream.
Another cause of failures can be conflicts with other applications that use the microphone, such as voice recorders or voice assistants, and close unnecessary background processes before important calls.
Why can the recording be interrupted?
Where are the records stored and how to transfer them
Understanding the structure of the Android file system will help you quickly find and save important conversations. By default, records are stored in internal memory in hidden or system folders, which can be restricted.
For Xiaomi’s full-time record, the path usually looks like this: MIUI/sound_recorder/call_rec. Files may have an extension.m4a or.mp3. If you use a third-party app, look for a folder with the program name at the root of internal memory or in the directory. Android/media.
It is recommended to back up important conversations regularly. You can set up automatic synchronization of the folder with records to the cloud storage (Google Drive, Yandex.Disk, Mi Cloud). To do this, select the folder with the call records for automatic download in the cloud service settings.
- 💾 Use a file manager with access to system folders to search for records.
- ☁️ Set up autoload to the cloud so you don’t lose data when your phone breaks down.
- 📂 Regularly sort files, removing unnecessary to avoid clogging memory.
Keep in mind that storing records of third-party conversations without warning may violate the laws of your country, and use this function responsibly and only for personal purposes or with the consent of the interlocutor.
💡
The most reliable way to save a record is to send the file to your favorite messenger immediately after the call or upload it to cloud storage, since system files can be deleted when cleaning the cache.
