Xiaomi’s smartphones have long established themselves as one of the most functional devices on the Android market. However, one of the most popular features that often raises questions among users remains the feature of recording telephone conversations. In modern versions of the MIUI shell and the new HyperOS, this tool is built-in by default, but its operation can vary depending on the firmware region and the Android version.
The need to keep an important conversation with a customer, family or support team is a regular issue. Fortunately, you don't have to look for complicated workarounds or buy additional equipment. The system's regular recorder is able to automatically record incoming and outgoing calls, storing them in high quality right in the device's memory.
In this article, we will take a closer look at the details of the setup, look at the reasons for the lack of feature in your menu, and suggest effective alternatives: you will learn how to manage the archive of records, configure automation, and solve typical sound problems.
Built-in recording capabilities in MIUI and HyperOS
Starting with certain versions of the shell, Xiaomi engineers have implemented a native mechanism for recording audio at time, which is the most stable solution, since it works at the system level and does not require installing third-party software.
The interface may vary slightly depending on whether you have MIUI 12, 13, 14 or the new HyperOS. However, the logic remains the same: the system allows you to choose whether to record all calls automatically or only certain numbers, which gives you flexibility in managing disk space and privacy.
⚠️ Note: In some global firmware versions (e.g. Europe), the feature may be hidden due to strict privacy laws. GDPR. In this case, the standard methods to activate it will not work without changing the region.
If you find that your menu doesn't have the right item, don't get upset. Often, just change the region of the device to a country where such restrictions don't apply, such as India or Singapore, and after you reboot your smartphone, the desired section should appear in the call settings.
Step-by-step instructions for activating the function
To start using automatic recording, you need to configure the call parameters correctly. It takes only a few minutes and requires no special knowledge. Follow the algorithm to customize the device to your needs.
First, open the Phone app and find the menu icon or setting gears, which is usually located at the top right of the screen or at the bottom of the interface, find the Call Record section and activate the switch.
☑️ Set up automatic recording
Then the system will suggest you choose the mode of operation, you can set up a record of all incoming and outgoing calls, or you can create a list of favorite contacts, conversations with which will be saved, which is especially convenient for business users who need to record only communication with partners.
It is also important to pay attention to the item "Warn about recording." If this option is enabled, the interlocutor will hear a voice message that the conversation is being recorded, in some situations it is a requirement of the law, but if you want a hidden recording, this feature should be disabled.
Managing File Settings and Formats
The flexibility of Android allows you to fine-tune your audio file retention options. In the call record menu, you will find additional options that affect the quality and organization of the archive.
The default format is.m4a or.mp3. The first option provides better quality with a smaller file size, which is critical for long conversations. The second option is more compatible with older media players.
| Parameter | Description | Recommendation |
|---|---|---|
| Sound source | Microphone or system audio | System audio (clear sound) |
| File format | MP3, M4A, AAC | M4A (Quality and Size Balance) |
| Storage | Internal memory or SD-map | SD-map (to save space) |
| Duration | Recording time limit | No restrictions. |
Also in this section, you can find a path to the folder where the files are saved. MIUI/sound_recorder/call_rec And if you know that address, you can quickly find the file you want through the file manager or when you connect your smartphone to your computer.
💡
Use cloud services to sync your records folder so you don’t lose important data when your phone breaks down or resets.
What to do if the recording function is not available
Users often face a situation where, after upgrading or buying a new smartphone, the recording option disappears, a common issue with Google's regional restrictions and Android 10 and higher security policies.
The first step should always be to check the region. Go to Settings → Advanced Settings → Region. If you have Russia, Ukraine, Germany or another EU country, try changing the region to Singapore, India or the United States.
If the region change didn’t help, it’s possible that your device is running on an Android version where Google has completely blocked third-party and system apps from accessing the audio stream, in which case it’s almost impossible to solve the problem with regular means.
⚠️ Note: Installing modified firmware or obtaining superuser (Root) rights to unlock the feature may result in loss of warranty and disruption of banking applications.
There is also a hidden menu software method, but it doesn't work on all models. Try dialer code ##66## or similar combinations specific to your CPU, but in modern versions of HyperOS, these loopholes are often closed.
Third-party applications for recording conversations
When built-in tools are powerless, third-party apps come to the rescue, but because of Google Play’s tightening policies, many of them are unstable or require complex setup via ADB.
One of the leaders in this niche is the Cube ACR app, which can bypass system limitations using special availability services. To work properly, you may need to install an additional module (App Connector) through the Android special features menu.
- 📱 Cube ACR — supports recording via instant messengers (Telegram, WhatsApp, Viber) and ordinary calls, has flexible settings.
- 🎙️ Call Recorder - ACR — Classic solution with support for cloud download and automatic cleaning of old records.
- 🔊 TapeACall is a popular app, but many features are only available in the paid version, and recording often goes through conference calls.
When you install these programs, the system will issue a lot of security alerts, and you'll have to manually allow access to the microphone, the phone, the contacts, and most importantly, turn on a dedicated service in the special features settings, without this step, there will be no recording.
Why are there no voice calls in third-party applications?
Where to look for saved records and how to manage them
Once the conversation is recorded, it's important to know where to find it. All the records are duplicated in the Dictator app (yellow microphone icon) and in the call history. The call log will show a small coil or microphone icon next to the caller's number.
For quick access to files, open the Explorer app and follow the Internal Shared Drive path → MIUI → sound_recorder → call_rec. Here, files are sorted by date and time of creation. You can rename them, send them via messengers or delete them.
Archive management is an important part of smartphone maintenance. Audio recordings take up space, and if you don't keep track of them, memory can run out quickly. Set up automatic deletion of records older than 30 days in the voice recorder settings menu.
💡
Regular cleaning of the folder with call records frees up to 2-3 GB of space per month with active use of the smartphone.
Frequent problems and their solution
Even with the right setup, users can face technical difficulties, most often complaining about the lack of sound of the interlocutor or interrupting the recording in the middle of a conversation.
If you can't hear someone, check to see if "Write My Voice Only" is enabled, and try to turn off noise cancellation in the audio settings, as noise reduction algorithms can perceive the voice of the person as background and delete it.
- 🔇 No audio of the interlocutor – check the permissions of the application, try to disable VoLTE (sometimes conflicts), change the format of the recording.
- ⏹️ Recording is cut off - perhaps running out of disk space or the system shuts down the process to save energy.
- 📞 Recording doesn’t start automatically – check if the write limit is worth it for list-only contacts, and make sure that you’re not in the process of recording. SIM-The card is chosen correctly for the outgoing.
In some cases, the problem is using Bluetooth headsets. Not all headphones support audio streaming for recording. If you don't have headphones connected, try turning them off or using a built-in speaker.
