Modern Xiaomi and Redmi smartphones have powerful functionality that is often hidden in the depth of settings or requires activation through special combinations. One of the most popular features for gamers, bloggers and ordinary users is the ability to capture what is happening on the display. The built-in screencaster in the shells of MIUI and HyperOS allows you to do this without installing third-party software, providing high quality picture and sound.
However, many device owners don’t know how to activate this tool correctly or why it’s not on the standard menu. In this article, we’ll take a look at all the ways to activate, adjust quality and audio settings, and solve typical audio recording problems.
Standard method of activation through the notification curtain
The fastest and most obvious method, which is available on 95% of the brand's devices, is to use a quick access panel. First, you need to unlock your smartphone and swipe from top to bottom to open the control center. Here, among the Wi-Fi, Bluetooth and flashlight icons, you should find an item called Screen Recorder or Screen Recorder.
If you first click on a request to allow media access or display over other windows, you need to confirm it. Android requires this for data security. Once confirmed, a floating control panel will appear on the screen, allowing you to pause, stop the process or draw on the screen in real time.
In some cases, the icon may be hidden in the second page of the Quick Settings menu, and to find it, you need to click on the edit button (usually a pencil or three dots) and drag the recording icon to the active area, which makes the function available in one touch in the future.
💡
If you use screen recording frequently, fix the widget on your desktop via the widget menu – this will save time searching for the feature in the curtain.
Configuring quality parameters and resolution
Before you start recording a video stream, it is crucial to adjust the output options to make the final file meet your requirements. Standard settings can be set to low resolution to save space, which is unacceptable for creating content. Go to the Tools app and select Screen Record, then click on the settings gear in the upper right corner.
This gives the user access to a choice of resolution. For modern displays, it is recommended to set a value of 1080p or higher if the device processor allows. Frame rate setting is also available: 60 fps is better for smooth gameplay, whereas 30 fps is enough for writing static instructions.
⚠️ Attention: Setting the maximum resolution and bitrate significantly increases the size of the final file and the load on the processor, which can lead to heating of the smartphone body during a long session.
You can either capture portrait or landscape mode, or you can leave automatic determination, and you can do vertical video recording for TikTok or Shorts, and you can force portrait orientation to avoid black fields.
Audio system configuration: microphone or system sound
One of the most challenging screencasting tasks on Android has long been recording internal sound. In modern versions of MIUI, this problem is solved, but requires the right setup. In the screen recording menu, find the Sound section. Here you will find three main options: Microphone, System Sounds and No Sound.
Microphone mode records all external noises, including your voice and sounds from your phone's speakers. This is suitable for video comments, but the quality will depend on the acoustics of the room. Systemic sound mode captures the digital audio stream directly, providing a crystal clear sound of the game or application without extraneous noise.
It’s worth noting that some apps, especially streaming services like Netflix or banking programs, block audio and image recording for copyright and security reasons, and in such cases you’ll get a black screen or video without sound, and you can’t get around it with standard means.
| Parameter | Description | Recommendation |
|---|---|---|
| Microphone | Records external sounds | For video comments |
| Systemic sound | Records the sound of applications | For gameplay and tutorials |
| No sound. | Only video. | To demonstrate the interface |
| Show touch | Visualization of pressing | For educational videos |
☑️ Checking the sound settings
Hidden features via engineering menu and ADB
For advanced users who lack standard functionality, there are ways to activate hidden features. Some firmware versions offer the Android Debug Bridge (ADB) audio recording feature, which requires connecting your smartphone to your computer and having USB debugging in the Developer Menu.
The command to run the recording with internal sound through the terminal is as follows:
adb shell screenrecord --bugreport /sdcard/video.mp4Using this method bypasses some software limitations, but requires technical literacy. Also, in the engineering menu ##6484## (code may vary depending on the model), you can sometimes find test display modes that affect image rendering, although direct activation of the recorder is rare there.
⚠️ Note: Making changes through ADB Or an engineering menu can cause the system to run in an unstable way, and only use these methods if you understand the consequences of your actions.
The alternative is to use third-party launcher applications or specialized utility that implement their recording services into the system. However, the tool built into HyperOS often works more stable and is optimized for the specific hardware of Snapdragon or MediaTek processors.
Solving problems with no sound or black screen
The most common problem users face is the lack of audio track in the finished video, most often due to an application conflict: If one application has already captured the audio channel (for example, a voice recorder is running or a WhatsApp call is being made), the system can block access to the recorder.
Another common mistake is the power saving mode enabled. Aggressive battery optimization can kill the recording process in the background if you switch to another application. You need to add the Screen Recording app to the exceptions or the "No Limits" list in the battery settings.
Why does video slow down when playing?
It’s also worth checking the permissions in the app menu. Go to Settings → Apps → Screen Record → Permissions and make sure that microphone and storage access is granted. Without those permissions, the feature won’t be physically able to save a file or record a voice.
Using third-party applications as an alternative
If the built-in functionality doesn’t suit you or doesn’t work properly, Google Play offers a variety of alternatives, with XRecorder, AZ Screen Recorder, and DU Recorder leading the market, often providing more flexible bitrate settings and the ability to edit videos immediately after recording.
The main advantage of third-party software is that it has a built-in editor and can stream directly to platforms like YouTube or Twitch, but these applications often contain advertising and require more system resources, which can reduce FPS in games.
When choosing an alternative, pay attention to the permissions requested. If a simple recorder requires access to contacts or geolocation, this is an alarm. Xiaomi’s built-in solution is more secure in this regard, as it is part of the system shell and passes the manufacturer’s security check.
💡
The built-in Xiaomi recorder is optimized better than third-party analogues and does not waste the battery, so it is worth starting to find a solution to problems with its settings.
