Owners of Xiaomi Poco X3 Pro smartphones often face the need to record important conversations, whether it is business negotiations or communication with service services. The standard “calling” in the shell of MIUI offers built-in functionality for this, but its activation is not always obvious to users who have switched from other Android devices.
In this guide, we will explain in detail where the switches in the Poco X3 Pro system menu are hidden. You will learn how to set up automatic recording for all incoming and outgoing calls, as well as how to manage already saved audio files.
It is worth considering that depending on the version of the firmware (Global, EEA china ROM) The interface may vary slightly, but the logic of the Phone system application remains the same for the entire Xiaomi ecosystem. MIUI 12, 13 and 14: A deep understanding of settings will allow you to use your smartphone as efficiently as possible.
Activation of a function in a standard application
To get started, you need to open a standard call app, which usually has a green phone icon with a phone signature, and it's here, rather than in the general settings of the system, that you resides the main control toolkit. In the upper right corner of the screen, you'll see a three-dot icon or a gear that indicates the menu of additional options.
The list that opens will include Call Recording, and the interface may suggest that you immediately turn on the automatic recording or go to the submenu for detailed settings. If you want to record conversations selectively, just activate the top switchboard, and then a button will appear on the screen during the conversation, but a deeper setup is required to fully automate the process.
It is important to note that the quality of the recording depends not only on the software settings, but also on the operation of the Poco X3 Pro microphones. The device is equipped with several microphones for noise reduction, and the system automatically selects the optimal sound source. In some cases, especially when using headsets or hands-free communication, the algorithms can work in different ways, which is worth considering when checking the first recordings.
Once the basic function is enabled, the system can request confirmation that the interlocutor will be alerted to the recording by voice message, a requirement of many countries, which Xiaomi does not recommend ignoring this fact, since the notification will be played at the beginning of each conversation if the feature is active.
Set up automatic recording and filters
When you log into the Call Record menu, you'll find more subtle controls, and you can activate Automatic Call Record mode, which will eliminate manual clicking of a button, and you can choose to use it to record all calls, whether they're just outgoing or incoming, and this approach saves space in the device's memory by sifting out unnecessary dialogs.
The feature, “Record calls from numbers that are not in contacts,” is critical to protecting against fraudsters and recording conversations with unknown subscribers, which are often ignored by standard settings, and by activating this switch, you are guaranteed to save information from couriers, delivery services or potential scammers, even if their numbers are not stored in the phone book.
You can also set up a way to remove specific numbers from the automatic entry list, which is useful if you want to keep a record of business correspondence, but prefer not to save personal conversations with loved ones, and this uses a "Do Not Write" list to add favorite contacts, and this list is managed through the same menu of recording settings.
☑️ Set up automation
Remember to check the amount of free space periodically, as audio files, especially in high quality, can take up a significant amount of memory. Although the Poco X3 Pro has a fast UFS 3.1 storage, overflowing the disk can lead to failures in the system as a whole.
Audio formats and sound quality
The format of stored files is often questioned in recording settings. By default, MIUI can use MP3 or AAC (in an M4A container). AAC format provides better sound quality with a smaller file size, which is the preferred choice for most users. Switching between formats is done in the recording settings menu, if your firmware version allows it.
Record quality on Poco X3 Pro also depends on the codec used by the carrier. If the conversation is going through a VoLTE network (Voice over). LTE), sound HD-quality, and the recording will be clear and legible, in poor coverage or when switching to standard networks. 2G/3G The quality may decrease, and the voice of the interlocutor will become more deaf or intermittent.
There is a common misconception that you can dramatically improve the quality of recording by third-party applications. In fact, the Phone system app has priority access to the audio stream. Third-party programs often have to use workarounds by recording sound through the microphone, which leads to echoes and noises, especially if you speak through a speaker.
💡
Use the AAC format to save space: It delivers excellent voice quality at a file size nearly half that of MP3.
No special software is required to listen to the recordings. A standard Xiaomi player or any third-party audio player will play files without any problems. If you plan to transfer the recordings to a computer, the MP3 format may be more compatible with older systems, although modern OSes read any formats.
Where files are stored and how to manage them
All recorded conversations are stored in the device's internal memory in a hidden system folder. /MIUI/sound_recorder/call_rec. However, users do not need to search files through Explorer, since the Phone app itself has a convenient tab to view the history. By clicking on the contact name or number in the call log, you will see a play button if the record was recorded.
For mass file management (deletion, copying, forwarding), it is better to use the built-in Dictator or Sound Recording application, where all files are sorted by date and type (call, voice recorder, FM-You can select a few records and send them via Bluetooth, Wi-Fi or messengers, and you can also rename files for easy search.
When connecting a smartphone to a computer through USB-The folder cable can be displayed as a separate category or be located in the back of the system directories. MIUI, Turn on the display of hidden files in the Explorer on the PC, which will allow you to back up important conversations on the hard drive.
| Parameter | Description | Recommendation |
|---|---|---|
| File format | Type of audio coding (MP3/AAC) | Selecting AAC to save space |
| Sound source | Microphone or system flow | System flow (automatically) |
| Storage | Disc location | Internal memory, folder. Call_rec |
| Duration | Recording time limit | Limited to free space only |
Synchronizing records with the Mi Cloud or Google Drive cloud is usually disabled by default to save traffic. If recording a conversation is critical, it is recommended that you send the file to the Favorites messenger or cloud storage immediately after the call, this will protect data in the event of loss or breakage of the smartphone.
Problems with recording on global firmware
Global ROM users may face a lack of recording or voice alerts in English, due to legal restrictions in different countries, and some regions, such as India or Europe, may have more stringent recording notification requirements than Russia or China.
If the recording feature is completely absent from the menu, it may mean that your version of Google’s Phone app does not support this option for your region.In such cases, users sometimes change the region in the system settings to Singapore or Indonesia, where the features can be unlocked, but this is not a guaranteed method and may affect the operation of other services.
⚠️ Warning: Changing your smartphone settings may result in ads in system applications or changes to preinstalled programs.
Another common problem is silent recording of the voice of the interlocutor, which is often solved by turning off the “Noise Reduction” function in the special settings or during the call itself. However, on the Poco X3 Pro, you should be careful with turning off noise cancellation, as this can worsen the overall quality of communication in noisy places.
Why is the recording interrupted?
Use of third-party applications
If Xiaomi’s built-in tools don’t suit you, Google Play offers dozens of alternatives; popular apps like Call Recorder or Automatic Call Recorder can upload recordings directly to the cloud, recognize speech, or encrypt files; but installing them on Android 11, 12, and higher (which is the basis of MIUI) is difficult.
Since Android 9, Google has restricted third-party apps from accessing the audio stream during a call, often recording only your voice and hearing the person very quietly or through a speaker, often requiring an ADB connection or Root rights to function properly, which is a difficult procedure for the average user.
However, some developers find workarounds using the Accessibility Service.The app automatically presses the record button on the screen when a call starts.This works, but requires constant activity of the app in the background and can consume the Poco X3 Pro battery faster.
💡
The built-in Phone app from Xiaomi provides the best recording quality and stability compared to third-party counterparts on new versions of Android.
Security and legal aspects
Recording telephone conversations is a subject of law, and in most cases, recording one's own conversation for personal use is not prohibited, but using the records in court, posting them online, or sharing them with third parties without the consent of the interlocutor can entail legal liability.
Always keep your privacy in mind. If you're recording a conversation that contains personal information, passport information, or banking information, keep those files in a secure folder. MIUI has a Hide Files feature that allows you to block certain files with a password or fingerprint.
⚠️ Warning: Do not transmit commercially sensitive or privately sensitive communications through unsecured channels, which may result in leakage of information.
For businesses, using automatic recording is often the standard for employee quality control. In this case, it is recommended to alert customers to recording at the beginning of a conversation, which is good business practice and reduces the risk of conflict. Poco X3 Pro with its powerful Snapdragon 860 processor easily copes with background recording even when multitasking.
