Xiaomi’s current smartphones, which run MIUI shells and the new HyperOS, have built-in functionality for recording phone conversations, an option critical for lawyers, sales managers, and anyone who needs to save evidence or details of a conversation. However, standard settings often require manual activation, as the default feature can be disabled for privacy purposes.
The configuration process does not require the installation of third-party applications, which guarantees the stability of the system. You just need to set the parameters correctly in the call menu. In this manual, we will discuss in detail all the steps necessary to activate automatic or manual recording, and also consider the nuances of working with the volume of the interlocutor.
To get started, make sure your device has enough free space, files can take up a significant amount of memory, especially if you plan to archive long conversations in high quality, and then we will move on to direct function management through the system application Phone.
Activation of the recording function in the standard application
The first step is to log in to the regular call settings. The interface may vary slightly depending on the firmware version, but the logic remains the same for all Redmi and Poco models. Open the Phone app and find the menu icon, which is usually represented by three dots or a gear in the corner of the screen.
In the list that opens, you need to select Settings, and here you are interested in the Call Record section, and this is where all the key switches that control the voice recorder's behavior during a conversation are concentrated, and without activating this module, you can't set up any further.
Once you go to the menu, you'll see the main call recorder, which needs to be put into an active position, and the system can request confirmation of actions, warning that the person may be notified of the recording by voice message, depending on the legislation of your region.
- 📱 Open the Phone app and click on the three dots in the upper right corner.
- ⚙️ Select “Settings” from the drop-down list and find the “Call Record” section».
- ✅ Activate the “Record Calls” switch to start the function.
It is important to note that in some regions the function may be hidden or limited. If you do not see the described items, check the region in the phone settings or update the Phone app through the GetApps store. Correct activation is the foundation for further fine-tuning the sound parameters.
Automatic and manual recording modes
Once the basic function is enabled, the user has to choose the mode of operation, automatic recording allows you to record all incoming and outgoing calls without your participation, which is convenient for full control, but quickly fills the device's memory with unnecessary files if you often talk about nothing.
The alternative is manual mode, where you only start recording when you press a button on the screen during a conversation, which is more selective and allows you to control which dialog you're going to save, and you can switch between modes depending on what you're doing.
And you can have a flexible filtering system that allows you to automatically ignore contacts from the phone book, or just record them, and it creates an effective filter that cuts off commercial calls or private conversations that don't require archiving.
☑️ Set up automation
⚠️ Note: When automatically recording all numbers, make sure you have cloud sync enabled or you clean your memory regularly, otherwise the phone may stop accepting new calls due to storage overflow.
Choosing the right mode has a direct impact on the usability of your smartphone in your daily life, and if you work in the service industry, automation will be an indispensable assistant, and for personal use, it is more often recommended to manually start or write only unknown numbers.
Loudness and sound quality setting
One of the most common problems users have is the quiet voice of the interlocutor in the recorded file. In the settings of recording calls on Xiaomi, the option “Use speaker” is often present. When activated, the phone will automatically turn on the speaker when recording begins, which greatly improves the audibility of the second side.
However, hands-free is not always convenient, especially in public places, where recording quality depends on the main microphone and noise cancellation. Some Xiaomi models allow you to choose the source of sound or adjust the sensitivity of the microphone, although this option is not available on all versions of Android.
The file-saving format also plays a role. Commonly used MP3 or AAC. These formats provide a good balance between sound quality and file size. Selecting a higher bitrate will increase the size, but may be necessary for legally relevant conversations where every detail matters.
- 🔊 Activation of the option “Loud communication” improves the intelligibility of the interlocutor’s speech.
- 🎙️ Check the main microphone by covering the bottom hole with your hand during the test recording.
- 💾 Format MP3 It is optimal for long-term storage of archives of conversations.
💡
If the voice of the interlocutor is barely audible, try to slightly move the top of the phone from the ear during a conversation, without turning off the screen to improve the sound capture by the main microphone.
Experiment with the position of the phone during test calls. Sometimes even a small angle of the device affects how the sound wave enters the microphone holes.
Managing exclusions and selected contacts
The flexibility of MIUI allows you to create precise rules for recording, so you can set up a script that only records numbers that are not in your phone book, and it's ideal for recording conversations with couriers, support services, or potential scammers.
On the other hand, there is a record mode only for contacts from the Favorites list or a specific group, which is relevant for business users who want to keep a history of negotiations only with key partners or customers, ignoring personal calls.
To manage these lists, you need to go to the recording settings subsection, where the current status is usually displayed (“All numbers”, “Not from contacts”, etc.). By clicking on this item, you will see a list of available options for choosing a voice recorder behavior strategy.
| Recording mode | Description of action | Recommended use |
|---|---|---|
| All rooms. | Records every incoming and outgoing call | Lawyers, full archiving of activities |
| Numbers are not from contacts. | Ignoring saved numbers, writes unknown | Protection from fraudsters, fixation of deliveries |
| Selected numbers | Recording is made only on a specific list. | Business negotiations with key clients |
| Manually. | Automation is disabled, start on the button | Personal use, rare recordings |
Using exceptions helps save time sorting files later, so you don't have to listen to hours of unnecessary conversations to find one important point, and having filters configured correctly is a sign of an advanced user.
Search, listen and synchronize files
There are two main ways to find the stored records, the first is through the phone call history, and next to the number you've been recording, you'll see a special voice recorder icon, and you'll click on it and you'll immediately go to the file you've been listening to for that particular call.
The second way is through the Dictator or Explorer app, and in the system directory, files are usually lying in the path. MIUI/sound_recorder/call_rec. It's convenient to do mass operations like renaming, deleting, or copying files to a computer. File naming structures often contain a date and time, making it easier to search.
