Owners of modern smartphones Xiaomi, Redmi and POCO often face a situation where the device begins to automatically record every incoming or outgoing connection. This behavior is standard for the shell MIUI and its Chinese counterpart HyperOS, where the function is activated by default to ensure security and store important information. However, constantly recording dialogues can quickly overflow the device’s memory and create chaos in the archive of audio files, forcing the user to look for a way to deactivate this option.
The process of disabling does not require root rights or complex manipulation of system files. All the necessary settings are hidden in the depths of the menu of the standard Phone application, which is a system component of the Android operating system with an overlaid shell of the manufacturer. Understanding the logic of this module will allow you to flexibly manage the parameters of audio capture, choosing between a complete ban, automatic mode for all numbers or selective fixation only for contacts from the address book.
In this article, we will take a detailed look at the algorithm for different firmware versions, explain the difference between the global and Chinese versions of the interface, and also look at the nuances of how the function works in the context of changing privacy laws. You will learn not only to turn off the switch, but also to understand how the automatic writing mechanism works to configure the device as convenient as possible for yourself.
Where to find the recording settings in the phone application
The first step to managing audio capture is to log in to the system caller's settings menu correctly. Unlike many other applications, there is no separate desktop icon; all settings are hidden inside the dialing interface itself. To begin, open the standard Phone app, which usually has a green handset as its logo and is located in the bottom dock of the screen.
When you start the app, look at the top right or left corner of the screen, where you have an icon with three vertical or horizontal dots, and this menu causes a drop-down list where you want to select Settings, and this is where you have all the parameters that you need to look at the behavior of the system caller, including locking numbers, defining Caller ID, and of course, managing the audio tracks of the dialogues.
In the list that opens, look for a section called Call Recording. Depending on the MIUI version or the regional features of the firmware, this item may be immediately on the main list or grouped under "Additional." If you use the Chinese version of the firmware, the names may differ, but the menu hierarchy remains similar. In some cases, especially on older versions of Android, this item may be simply called "Automatic Recording."
⚠️ Note: On devices with global firmware (Global) ROM) The menu item may be called "Call Recording" and in Chinese versions (China) ROM) — «». If you can’t find this section, make sure your region in the system settings is not worth India or Europe, as in some countries the recording feature may be software-limited or hidden by the manufacturer due to local privacy laws.
Once you've got a menu, you'll see a few switches. The top one is usually responsible for turning the whole function on or off. Below are some more subtle settings, such as "Automatically record calls" or "Record calls from unknown numbers." To completely stop the dialog fixing process, you need to put the master switch inactive, but for flexible settings, you'd better leave the function on but change its logic.
Turning off automatic recording for all calls
The main reason users want to change their settings is because they don't want to save every conversation, and by default, the system can be set to automatically start recording on any connection, and to fix that, log into the Call Record menu and find the Auto Record Calls switch, which turns the function into manual mode.
Manually, recording a conversation won’t start on its own. Every time you make or receive a call, a button (usually in a circle or cassette) will appear on the screen, which will initiate the recording, which is the most convenient format for most users, since it gives full control over the process and saves space in the device’s memory.
Also, you should pay attention to the option "Record calls from unknown numbers." If this item is active, even if the general automatic recording is turned off, numbers that are not in your address book will be fixed. This is useful for fighting spam or fraud, but may be unnecessary for normal communication.
It is important to understand that disabling automatic recording does not delete pre-existing files. MIUI/sound_recorder/call_rec Until you decide to manually clean them, and once you change the settings, the system will immediately apply the new rules, and the next calls will be handled according to your choice.
Selective recording for contacts from the list
There is a scenario where the user needs to keep conversations only with certain people, such as customers, suppliers or close relatives, while ignoring the rest of the calls. MIUI This allows you to implement such flexible logic by configuring exceptions or selective lists.
To activate this mode, in the recording settings menu, find the "Record Calls" option (or similar one depending on the OS version). Here you will be asked to select the source of the numbers. Select the "Selected Contacts" option or "Only Contacts from the List" option. After that, the system can suggest you go to the address book to mark specific people whose dialogues are to be fixed.
An alternative approach is to use the "Write Everything Except..." function, in which case you activate the global automatic record, but add to the exception list numbers that you don't need to write down, which is less convenient if there are many, but effective for a narrow circle of trusted people.
- 📱 Open the call record settings and select the “Selected Contacts” mode».
- ✅ Go to the address book and tick the necessary names.
- 🔇 Make sure the “Write Unknown Numbers” option is turned off to avoid missing important calls from new contacts.
With this setup, the recording indicator will only light up when you connect to a tagged subscriber. This helps keep the archive in order and not waste time listening to useless dialogues. Remember that the address book syncs with your Google or Mi Account account, so the sample entry settings can be applied to other Xiaomi devices when you sign in to the same account.
Storage management and file formatting
Audio files take up space in the internal memory of the smartphone, and when you record hundreds of conversations a day, this can be a problem. The system allows you to control not only the process itself, but also the parameters of saving files. In the menu of recording settings, you can often find the item "Record Format" or "Sound Quality".
Modern versions of MIUI and HyperOS use MP3 or AAC by default, which provide good quality at a relatively small size. Older versions could use AMR, which takes up less space but has worse sound quality. The choice of format affects the compatibility of files with other devices and media players.
| Parameter | Description | Recommendation |
|---|---|---|
| MP3 format | High quality, compatibility with all players | Recommended for important conversations |
| AAC format | Good quality, smaller file size | Optimal balance for daily use |
| The way to preserve | Default folder in the system partition | Don't change it unless you need to. |
| Restriction of memory | Automatically delete old records | Enable if memory is limited |
Also in this section, there is often a feature called “Size Limit” or “Delete old records,” so you can set the system to automatically erase records over 30 days or when the free space in the “Call Records” section exceeds a certain limit (for example, 500 MB), which will prevent overflowing memory and slowing down the smartphone.
Where are the records physically stored?
Nuances of work in different versions of MIUI and HyperOS
The interface and availability of recording features can vary significantly depending on the version of the operating system and the region for which the device is released. Global ROMs often have restrictions related to the laws of the European Union and the United States, where it is required to notify the interlocutor about the record or completely ban the function.
HyperOS, which replaced MIUI, has made the interface more minimal, menu items can be regrouped and switches can be re-engineered, for example, new versions have the ability to synchronize records with the Mi Cloud cloud storage, which requires separate configuration and subscription.
- 🌍 Regional restrictions: In some regions (USA, Canada, individual EU countries) the recording function may not be fully available software, even if the phone hardware supports it.
- 🔄 System Updates: After a major Android update (for example, 11 on 12 or 12 on 13) the recording settings may reset to factory, and the automatic recording will turn on again.
- 📞 Third-party calls: When you install alternative calling apps (Google Phone, Truecaller), Xiaomi’s system recording function may stop working or conflict with the new app’s features.
If you’ve upgraded to the latest version of HyperOS and can’t find the old settings, try searching inside the phone’s Settings menu. Type the word “record” or “record” and the system will redirect you to the desired hidden partition. This is especially true when the menu structure changes between major versions of the firmware.
⚠️ Note: The use of the call recording function is regulated by your country of law and in many jurisdictions, recording a conversation without warning or obtaining the interlocutor’s consent is illegal. Make sure your actions do not violate privacy and data protection laws.
Solving problems: why the record doesn't work or shut down
Sometimes users are faced with a situation where, despite the correct settings, the recording does not start or, conversely, does not stop. One of the common reasons is a lack of free space in internal memory. If the partition is full, the system blocks the creation of new files, and the recording function may behave incorrectly.
Another common problem is conflict with optimizer or antivirus applications. Aggressive energy savings in MIUI can kill the recording process in the background, considering it as an extra load on the processor. To avoid this, you need to add the Phone and Dictophone app to the battery exclusion list.
☑️ Diagnostics of recording problems
Also worth checking is the app permissions. Go to Settings → Apps → All apps → Phone → Permissions. Make sure that microphone and memory access is allowed. If memory access is limited, the app will not physically be able to save the audio file even if the recording process is visually enabled.
In rare cases, cleaning the phone app cache will not delete your contacts or call history, but will reset temporary files and interface settings, which can eliminate software glitch that interferes with the function’s proper operation.
