Owners of Xiaomi smartphones often face the need to save important information voiced by the interlocutor during the call. The regular functionality of the MIUI shell and the new HyperOS provides for a built-in voice recorder, but in the latest versions of the software its activation can be hidden or require a change in region. Understanding the algorithms of the system will help quickly solve the problem without installing third-party software.
To make matters worse, Google’s privacy policies and local laws dictate their own rules for storing audio data, which is why settings can look different even on the same device models. In this article, we will discuss all the current methods for activating the feature, including hidden settings and alternative options.
Recording a conversation is not just a recording of sound, but an important tool for business negotiations, confirming support agreements or saving memorable moments. The built-in automatic recording mechanism allows you to avoid distractions during the dialogue. The user only needs to correctly configure the system once to make it work independently.
It’s worth noting that the quality of the final file depends not only on your Redmi or Poco microphone, but also on the method of encoding you choose. Standard settings usually offer a balance between file size and speech clarity. However, in some cases, especially with poor network signal, the system can prioritize the stability of communication, which will affect the audio stream.
Built-in MIUI and HyperOS capabilities
Starting with specific firmware versions, Xiaomi engineers integrated the recording module directly into the standard “caller,” which is the most stable and energy-efficient way, since it works at the system level, rather than as a separate application. To access these features, you need to go to the dial menu and open the settings through a three-dot menu or gear.
Here, the user finds Call Record, which gives access to detailed configurations, and you can choose to automatically record all incoming and outgoing, only certain numbers or manually selected contacts, and the flexibility of settings allows you to tailor your smartphone to personal needs, such as recording only conversations with your boss or customers.
⚠️ Note: When you turn on automatic recording, the system can play a voice warning to the interlocutor that the conversation is being recorded, this is a requirement of the legislation of some countries, and it is impossible to circumvent it with regular means without root rights.
Files are saved in internal storage in a folder MIUI/sound_recorder/call_rec. They are accessed through a standard conductor or a sound gallery.
💡
Use the AAC storage format for better compatibility with other devices, although MP3 takes up less space.
Problem of lack of function depending on the region
Many users notice that after upgrading or buying a device, there is simply no recording option at the settings point. This is not a defect or an error, but a conscious restriction imposed depending on the selected region in the Settings → Additional Features → Region. In some jurisdictions, recording conversations without notifying the second party or even prohibited.
To get the function back, you just need to change the region to a country where there are no such restrictions, and the leaders in loyalty in this regard are traditionally considered Indonesia, India, Singapore or Malaysia, and after changing the region, the interface of the caller may change slightly, and the call settings menu will appear the desired switch.
The process of changing the region is safe for personal data, but it can affect the operation of some services, news feeds and recommended applications, and the set of pre-installed themes and fonts can also change. If you do not want to change the region globally, you can try to temporarily switch, activate the record, and then return the original settings, although in new versions of MIUI the function may disappear again.
- 🌏 Changing the region to Indonesia often guarantees the emergence of a function.
- 📁 The path to files remains unchanged regardless of the country chosen.
- ⚙️ The interface can become partially English when changing location.
Step-by-step instruction for recording activation
For those who have already changed region or have the default feature, the algorithm is simple but requires careful attention. First, open the Phone app (blue handset) and go to settings. Find the Call Record section and activate the slider.
You have to adjust the rules, you can choose to record all numbers or only a select few, and you should pay special attention to the "Warning of Recording" item if you want to comply with etiquette or legal regulations, and once you turn on, the system will create the first test record that you can listen to immediately.
☑️ Activation checklist
It's important to check where files are stored. It's internal memory by default, but some models that support microSD cards can use external storage, and this is true for users who are actively chatting and talking, filling in gigabytes of data.
| Parameter | Description | Recommendation |
|---|---|---|
| Format | MP3 or AAC | AAC for quality, MP3 for compatibility |
| Source | Microphone or system sound | System sound (if available) |
| Storage | Phone memory / SD-map | SD-space-saving map |
| Notification | Sound signal | Include to avoid problems |
Third-party applications for recording calls
If standard methods don’t work or the functionality seems limited, Google Play apps come to the rescue. However, it is worth considering that starting with Android 9 and above, Google’s security policy severely limited third-party programs’ access to the audio stream, which means that many applications can only record your voice, and the voice of the interlocutor will be barely audible or absent.
One of the most effective solutions is the Call Recorder app, ACR or Automatic Call Recorder from Appliqato, which requires additional permissions and possibly a special plug-in for your phone model, and often needs to enable the “Alternative Method” or “Enable Speaker” mode in the settings of such programs to record both sides of the conversation.
⚠️ Warning: Third-party programs can use up battery power faster because they constantly monitor telephony status, and they can conflict with noise cancellation.
When you install, pay attention to permissions. The app needs to have access to a microphone, phone, and storage. Without these rights, recording is impossible. Some advanced utilities offer downloading records directly to the cloud (Dropbox, Google Drive), which is a great feature for backup.
Why have third-party apps stopped working?
Customization of quality and storage format
Record quality is a trade-off between file size and speech legibility. In the settings of the built-in voice recorder, you can usually choose the bitrate. For normal conversations, low values are enough, because human speech does not require a wide frequency range. However, if you are recording, for example, a musical fragment or complex technical analysis, the settings need to be increased.
The AAC format provides better quality with a smaller file size compared to MP3, but may not be readable on very old computers without codecs. WAV format gives maximum quality without compression, but files take up a lot of space and quickly fill up the smartphone's memory. MP3 with a bitrate of 64-128 kbit/s is best for archiving.
Remember to clean your records regularly. Automatically recording all calls can take several gigabytes per month. In the recording settings, you can set a limit: for example, keep files for 30 days or delete the oldest files if there is a shortage of space, which will prevent the situation when the phone will stop receiving calls due to overflow of memory.
- 🗑️ Set up autodelete records older than 1 month.
- 💾 Use cloud services for long-term archives.
- 🎚️ Choose a bitrate not lower than 64 kbit / s for legibility.
💡
The optimal balance between quality and file size is achieved using AAC format and 96 kbit/s bitrate.
Legal aspects and ethics of recording
The use of the telephone recording function is regulated by the laws of the country in which the recording of one's own conversation for personal use is permitted, but publication, sharing with third parties or using the recording in court without warning may be illegal.
In business correspondence, it is customary to alert the counterparty to the record, which is not only legally competent, but also ethical. Xiaomi's built-in tools often have a voice notification option that sounds at the beginning of a conversation, and ignoring this point can lead to legal consequences if the record becomes evidence.
In addition, banks and government agencies often warn themselves about the recording, in which case a double record (your and theirs) can create a conflict of audio streams, which will lead to interference, and in such situations, it is better to rely on their archives, requesting it officially if necessary.

Solving recording problems
A common problem is that the recording is broken or the file is empty, and this may be due to Screen Recording or other audio services that capture the microphone, and the culprit may be the aggressive MIUI energy saving mode, which kills the recording process to save charge.
To fix this, you go to the battery settings, find the Phone or Dictator app, and set the No Limits mode. It's also worth checking the permissions: the app must have access to the microphone and storage, sometimes cleaning the phone app cache through the app menu helps.
If the speaker is quiet, try not to close the bottom of the screen where the noise reduction microphones are located during a conversation, and also make sure that you do not use a case that covers the microphone holes. In extreme cases, turning on the hands-free communication improves the speaker's recording, but worsens the overall acoustics.
