Modern Xiaomi smartphones with a shell MIUI or HyperOS have a wide range of functionality that often goes beyond the standard capabilities of the Android operating system. One of the frequent tasks for users is the need to capture important information voiced during a video conference or voice call through a popular messenger. Unlike conventional phone calls, recording VoIP traffic, which includes Skype, has its own technical features and security limitations.
The problem is that Google’s privacy policy and Skype’s own actively prevents direct recording of sound inside the app by blocking access to the microphone for third-party programs during a conversation. However, Xiaomi device owners are in a better position thanks to deeply integrated system tools. In this article, we will discuss how to circumvent software restrictions and record a conversation using an embedded voice recorder or specialized software.
Before you start setting up, it is worth noting that the quality of the final recording will directly depend on the chosen method and model of your smartphone. Flagship devices cope with the coding of sound better than budget models, but the right approach allows you to get a great result on any gadget. The key point is the use of the Xiaomi system recorder, which is able to capture the internal sound of the system, bypassing the locking of access to the microphone.
Built-in dictaphone MIUI: the main method of recording
The most reliable and easy way to capture a conversation is to use the pre-installed Dictophone app. Xiaomi engineers have implemented a unique system audio capture feature in their shell that allows you to bypass Android’s restrictions on recording audio from other applications. This solution does not require third-party software installation and works consistently on most current versions. MIUI.
To get started, you need to open the standard Dictophone app and go to the settings, usually a gear icon or three dots in the corner of the screen. Find Record Type or Sound Source and select System Sound or Microphone and Speaker. It is the switch to system sound that allows the Dictaphone to "hear" what is happening inside the Skype app, even if it is folded.
Once you have set up the audio source, start the recorder and press the record button. Now, without turning off the recorder, go to the Skype app and start a conversation. You will see that the record indicator continues to work, and the sound levels respond to the voices of the interlocutors. It is important not to turn the recorder completely, but only to switch between the windows so that the system does not stop the background recording process.
💡
If the system sound is recorded quietly, try to increase the volume of the media with buttons on the smartphone body, but not to the maximum, to avoid digital distortion (clipping).
It is worth considering that on some global versions of firmware, especially those certified for Europe, the system audio capture function may be limited by legal regulations, in which case the recorder will write only in silence or from the microphone, ignoring the voice of the interlocutor from the speaker, in which case you will have to resort to alternative methods described below, or use loud communication.
Setup of system ekranoplan for video calls
If your Skype conversation involves video and you need to keep the visual component of the dialogue, a built-in voice recorder will not be enough, in which case the Screen Recording feature, which is also built into the MIUI shell, comes to the rescue.
To activate this function, call the curtain control panel and find the Screen Record icon. If it is not visible, click on a pencil or three dots to edit the panel and drag the icon to the active zone. Before recording, click on the gear in the ekranoplan interface and in the Sound section, select the System Sound source or Microphone source if the first option is not available for video calls.
An important nuance is the permission to display over other windows. When you first start, the system may ask permission to "Write Secure Content" or "Master on top of other applications." The permission must be granted, otherwise during a Skype video call, the screen may simply turn black, and instead of the interlocutor you will record a black background.
☑️ Preparation for video call recording
Once you start recording the screen and start the video call, make sure the sound is transmitted correctly. Sometimes Skype may block audio capture when the video is on for privacy reasons, in which case the only way out is to turn on the speakerphone and record the sound through the microphone, although the quality will be lower due to possible echo effects.
Third-party applications for recording calls
When built-in tools are not enough or they are not working properly, users turn to third-party solutions from the Google Play store. However, with the release of Android 10, 11, 12 and later, security policies have become stricter, and many applications have lost the ability to write sound directly from the system.
One popular solution is Call Recorder's Cube ACR app, which supports recording calls from various instant messengers, including Skype, Viber and WhatsApp. Once installed, the app will request a number of permissions, including access to a microphone, phone and, critically, "Special Features." Without activating this item in the system settings, recording sound from VoIP applications will not work.
Another option is to use applications that create a virtual audio device, but they often require complex setup via ADB or having Root rights, which is not recommended for ordinary users. Most simple voice recorders in the Play Market will only write silence when trying to turn them on in parallel with Skype, since the system gives priority to the messenger.
⚠️ Note: Third-party apps may have access to your personal data and conversations. Use only proven, high-rated software and carefully review the list of permissions requested before installing.
It’s also worth mentioning that some “heavy” recording apps can cause conflicts with the sound drivers on the Snapdragon or MediaTek processors used in Xiaomi smartphones.This can cause the sound in Skype itself to become intermittent or disappear altogether.
Table of comparison of recording methods
To make it easier for you to choose the best way to capture a conversation, we have prepared a comparison table that will help you assess the pros and cons of each method depending on your goals and smartphone model.
| Method | Sound quality | Video recording | Difficulty |
|---|---|---|---|
| System recorder | High (digital) | No (audio only) | Low. |
| Screen recording | Medium/High | Yes. | Low. |
| Third-party annexes | Depends on the software. | No. | Medium |
| Second device | Low (echo, noise) | Maybe. | Low. |
As you can see from the table, pure audio recording is best suited to a built-in voice recorder with a system sound mode. If you need a video sequence, the ekranoplane will be the best choice. Third-party applications should be considered as a backup option when the regular funds for some reason do not work.
Use of the second device and hands-free communication
In situations where software methods fail, or you’re using an older version of Android where Xiaomi’s features are limited, the analog method comes to the rescue: using a second smartphone, tablet or voice recorder that physically records the sound coming from the speaker of your main device.
To implement this method, use Skype to make the audio go through an external speaker, rather than through a conversational speaker at the ear. Place the recording device at an optimal distance — usually 15-30 cm from the sound source. Too close will lead to overloading of the microphone and wheezing, and far — to a lot of extraneous noise.
This has its drawbacks: poor recording quality, echoes, background noises, and possible interruption of conversations with notifications on the recording device. However, it is universal and works on absolutely all phones, regardless of the firmware version or brand.
How to improve the quality of recording on the second device?
Remember that when using this method, the main smartphone battery will be consumed faster due to the screen and speaker at high volume. Charge the devices before an important conversation or keep them connected to the network.
Legal aspects and ethics of recording
Before recording any conversation, especially business or personal, it is necessary to consider the laws of your country.In many jurisdictions, recording telephone conversations and communications over the Internet without warning all participants is illegal and can entail legal liability.
In the Russian Federation, according to article 138.1 of the Criminal Code and 24 of the Constitution, collecting information about a person's private life without his consent is prohibited, but there are nuances: if you are a participant in a conversation, the recording may be permissible for personal purposes, but publication or use of it in court without the consent of the interlocutor is often impossible.
Ethically, a hidden record undermines trust between people. In business correspondence, the record is often pre-arranged and the parties agree to a record. Privacy is a right for every user, and the technical capabilities of a smartphone should not be used to violate that right.
⚠️ Attention: The use of records made without warning as evidence in court may be considered inadmissible, and the actions of the recorder may be considered an offense.
Solution: Why there is no sound in the recording
One of the most common problems faced by Xiaomi users is the lack of audio in the final file, despite the correct setting of the voice recorder, most often due to the fact that the Skype application uses hardware acceleration or a secure audio output path that blocks interception.
Try changing the audio output settings in Skype itself. Go to Settings → Audio and video and try changing the output device if this option is available, or just switch the volume during a conversation. Sometimes restarting the Skype app after the recorder starts, but before the call starts helps.
The problem may also lie in MIUI's power saving settings. The system can aggressively "kill" the background recorder process, considering it unnecessary. Go to Settings → Battery and Performance → Application Management, find a Recorder and select No Limits mode. This will prevent the recording from stopping when switching to Skype.
💡
If system sound is not written, make sure that the system sound source is selected in the voice recorder settings, not the microphone, and the application is given all the necessary permissions in the security menu.
