Today’s Xiaomi Redmi smartphones have powerful functionality that often exceeds users’ expectations, especially when it comes to system capabilities. Recording phone conversations is one of those features that may be required at the most unexpected moment: to fix an important agreement, save evidence or just for the sake of memory. However, with the release of new versions of Android and the shells MIUI or HyperOS, the process of activating this option has become less obvious to many owners.
Unlike the older models, where it was enough to just press a button during a call, now the system can hide this feature or require additional settings due to Google's privacy policy. Chinese versions of firmware and Global ROM behave differently, which often confuses users. In this guide, we will analyze all current methods, including hidden settings and third-party solutions.
Don’t panic if you don’t find the familiar “Write” button in the call interface.The conversation recording feature is built into most Xiaomi modules at the hardware level, but is software-limited depending on the region of use.Properly configured, you can archive dialogs automatically or manually without loss of sound quality.
Built-in recording function in MIUI and HyperOS
To start with, the simplest and most reliable way that developers have in place for most regions: in the shells of MIUI 12, 13, 14 and the new HyperOS, the telephony module has a built-in voice recorder. To activate it, you need to open the standard Phone app and go to the settings menu, which is usually hidden under three dots or a gear in the corner of the screen.
In the settings that open, you'll find the "Record Calls" item, and that's where the key switch that activates the function is hidden, and once you turn on the "Automatic Record" slider, the system will start storing all incoming and outgoing calls to the device's memory, eliminating the need to manually press the write button every time you talk.
It is important to note that in some regions (e.g. India or EU countries) due to strict privacy laws, this clause may be missing or blocked.If you see a notice that the feature is unavailable, this means a software restriction for your current region.
⚠️ Note: When automatic recording is enabled, the system can play an audible signal or a voice warning to the interlocutor that the conversation is being recorded.
To fine-tune it, you can choose which numbers to write down, whether it's anything you don't know or just a select few, which helps you save space in your memory and not clog up your archive with unnecessary dialogue.
💡
If the standard recording button disappeared after the system update, try clearing the Phone app cache through the application settings, but do not delete the data so as not to lose your call history.
Automatic recording and filters setting
Xiaomi Redmi’s flexibility allows you to not only enable recording, but also manage it with high accuracy. The call recording settings menu includes the “Choose contacts” section, where the user can create an exception list or, conversely, a priority number list.
Automation is especially useful for business users who are negotiating with customers, and by setting up the filter “Write only unknown numbers”, you can control incoming calls from unfamiliar sources without wasting memory on conversations with loved ones.
- 📱 Open the Phone app and click on the settings icon.
- 🔊 Go to the Call Recording section and activate the main switch.
- 📂 Select a folder to save if the system offers a choice between internal memory and SD-card.
- ⚙️ Set up the rules: “All calls”, “Selected numbers” or “All except selected numbers».
Files are saved in a format compatible with most media players, usually in a format that is not compatible with the media player.m4a or.mp3. You can find them through the file manager on the way. MIUI/sound_recorder/call_rec. This folder structure is standard for the Xiaomi ecosystem.
☑️ Checking the recording settings
Problems with Global Versions (Global ROM)
Owners of smartphones bought officially in Europe or other heavily regulated regions often face a lack of a record button, which is due to Google, which provides the basic Android operating system, imposing restrictions on the audio recording API on Android 9 and higher.
However, Xiaomi often bypasses this limitation by changing the region of the device: Changing the region in the phone settings to "India," "Indonesia" or "Singapore" can unlock hidden telephony features.
To change the region, you need to go to Settings → Additional settings → Region. After changing the location, the interface may change a little, new widgets will appear, but most importantly, the Phone application may have the ability to record. If this does not happen immediately, it is recommended to clear the cache of the call application.
| Region | Probability of success | Features |
|---|---|---|
| India | Tall. | Often unlocks the function completely |
| Singapore | Medium | May require a reboot. |
| Russia | Depends on the version. | The new version of MIUI may not be available |
| Germany | Low. | Strict GDPR laws block the function |
⚠️ Warning: Changing region may affect some system applications, such as Explorer or Themes, and change the list of preinstalled widgets on the desktop.
What if the change in the region did not help?
Use of third-party applications for recording
When embedded tools are powerless, third-party apps come to the rescue, but because of Android's limitations, they don't work as efficiently as system recording, and the most popular solution is the Cube ACR app, which uses special methods to bypass locks.
To work properly, these programs require a wide range of permissions, including access to a microphone, phone and, importantly, special capabilities (Accessibility), without which the application will not be able to intercept the audio stream during a conversation.
Installing third-party software often requires disabling Play Protect protection or installing from unknown sources. Once installed, you must follow the on-screen instructions to activate App Connector in the special features settings.
- 📥 Download the Cube app ACR Automatic Call Recorder from a reliable source.
- 🔐 Provide all requested permissions, including access to contacts and microphone.
- 🔌 Activate the plugin for your phone model in the app settings.
- 🧪 Make a test call to check the quality of the recording and the presence of the interlocutor’s sound.
Note that on Android 11, 12, 13 and 14, the effectiveness of third-party applications can be reduced: the interlocutor can be heard very quietly or not at all, in such cases, it is recommended to turn on speaker communication during a conversation for better recording of sound.
Where records are stored and how to manage them
Once a record is made, it's important to know where to find it. Xiaomi Redmi uses a specific folder structure, and files are accessed through the Explorer or Files app.
The path to the archive usually looks like this: Internal memory → MIUI → sound_recorder → call_rec. So here, files are sorted by date and time of creation, and the system allows you to listen to them directly from the Phone app in the history of calls, and next to the subscriber's number, there will be a tape recorder icon.
Record management includes the ability to rename, delete and forward files. Long conversations can take up a significant amount of memory, so it is recommended to periodically transfer the archive to a computer or to the cloud storage.
For convenience, you can configure synchronization of the record folder with Google Drive or Xiaomi Cloud, which ensures that even if you lose or break your smartphone, important audio information will not be lost.
Frequent questions and technical nuances
Users often face questions about sound quality, compatibility and legal aspects during the setup process, and understanding the technical details helps avoid mistakes.
The quality of the recording depends on the codec used by the operator and the capabilities of the smartphone microphone. In VoLTE, the sound quality is higher, but the requirements for the recording system increase. If you notice that the recording is interrupted, check if you have an energy saving mode that can limit the operation of background processes.
💡
The quality of the speaker’s recording depends on the speaker’s volume: if you use a third-party app, increasing the volume during a conversation can improve speech intelligibility.
Also worth mentioning is the legal aspects: laws vary from country to country regarding telephone recordings, and sometimes you need to be warned, and use this function responsibly in your country's laws.
