Modern Xiaomi, Redmi and POCO smartphones have powerful built-in screencasting functionality that makes third-party apps redundant for most users. The built-in Screen Recorder tool is integrated into the MIUI and HyperOS shell at the system services level, ensuring stable operation and high quality of the final video. You do not need to search for hidden menus or install questionable software from unverified sources, since all the necessary functions are already activated by default.
However, standard settings do not always meet the requirements of advanced users, who may need to record the internal sound of the system or change the bitrate. In this guide, we will examine in detail not only the basic algorithm of actions, but also the hidden possibilities available through the engineering menu and the following: ADB-You'll learn to adjust the permission. 1080p You will also understand why some applications may not have sound.
Recording video content from a smartphone display is not just entertainment, but a useful tool for creating educational materials, fixing bugs in games or saving important moments in correspondence. Understanding the intricacies of Android codecs will allow you to get a professional result without losing the performance of the device during the process.
Activation and basic configuration of the function
The first step to get started is to correctly place the shortcut in the Quick Settings Panel. On most devices running MIUI 12/13/14 or HyperOS, this element is already present, but can be hidden in the secondary menu. To access it, you need to swipe top-down twice to deploy the full list of switches, and find the icon with the image of the camera.
If you don't have a standard icon, you can add it through the Control Panel editing menu, click on the pencil icon or the tripole in the corner of the screen, find Screen Record widgets in the list of available, and drag it to the active zone, and then the function will be available in one touch, which is critical for fast fixation of what is happening.
Once the icon is activated, a floating control menu will appear on the screen that allows you to start recording, take a screenshot or pause the process. Before starting, the system will prompt you to select the sound source, and here it is important to adjust the settings correctly so that the final video contains the desired audio sequence. To access the advanced settings, click on the gear or swipe the floating menu to the right.
☑️ Preparation for recording
Configuration of audio and video parameters
The quality of the final file depends on the resolution and frame rate settings you choose. In the screen recording settings menu, you can choose the resolution of 1080p, 720p or the native resolution of your display. For most scenarios, Full HD is the optimal choice, since it provides a balance between picture clarity and file size.
Special attention should be paid to audio settings, as this is where the most questions arise. The system offers three main modes: "Microphone", "System sounds" and "No sound" System audio mode allows you to record audio directly from applications, but has limitations associated with the security policy of Android.
Bitrate video is also adjustable, although by default it is set to "Recommended." If you plan to mount video or upload it to high-compression platforms, it makes sense to manually increase the bitrate to 20 Mbps or higher if the device's processor allows you to process such a stream without delay.
- 🎙️ Microphone: Records external sounds and your voice, perfect for gameplay comments.
- 🔊 System sounds: captures audio from games and apps, but can be blocked DRM-protection.
- 🔇 No Sound: Creates silent video useful for displaying interfaces without undue noise.
💡
Use System Sounds mode only in horizontal orientation if you want to avoid audio focus conflicts in some games.
Working with system sounds and Android limitations
Since Android 10, Google has implemented strict restrictions on capturing internal audio streams, which are implemented through a separate channel on Xiaomi smartphones that is activated only when selecting the appropriate item on the menu, but many users face a situation where there is an image in the recorded video, but there is no sound from the game or application.
This is because some applications, especially streaming services and encrypted messengers, mark their audio stream as secure, and in such cases, the operating system blocks the recording of sound for security and copyright purposes. It is impossible to circumvent this limitation by standard means, since this level is not the same_kernel_defense.
For games, the situation is different: most modern titles allow you to capture sound, but require the correct setting of the mixer. Make sure that the audio settings of the smartphone itself are not turned to zero, and also check whether the “Hearphones” mode is activated without the connected headset, which sometimes happens when using Bluetooth adapters.
⚠️ Note: When you try to record a screen in banking applications or incognito browser mode, you can get a black screen instead of an image.
Use advanced functions through ADB
For users who lack the capabilities of a standard interface, there is a method of activating hidden parameters through debugging via USB. By connecting the smartphone to a computer and installing ADB Tools, you can send a command that will force the recording of system sound even in cases where the interface offers only a microphone.
To perform this operation, you need to turn on the developer mode by going to Settings → About Phone and seven times click on the MIUI version. Then, in the Advanced Settings menu, activate “Debugging over USB” and connect the device to the PC.
adb shell settings put global settings_screenrecord_sound_audio 1This command changes the global variable of the system, allowing the capture of the audio stream, and then you may need to restart the device. It is worth noting that on new versions of HyperOS, this method can be blocked by the manufacturer, so its effectiveness depends on the specific version of the firmware.
- 💻 Computer: required for input ADB-team.
- 🔌 Cable: Use the original cable USB-stable-connection.
- 🛠️ Drivers: Make sure that ADB Interface drivers installed correctly.

Comparison of built-in recorder and third-party applications
Despite the functionality of the regular tool, many users turn to third-party solutions from Google Play. Popular applications like AZ Screen Recorder or XRecorder offer additional features such as drawing on the screen, a webcam in the corner and more flexible bitrate settings, but they require wide permissions and often contain advertising.
Xiaomi’s built-in recorder benefits from optimization as it works directly with CPU codecs, minimizing heat and battery consumption. Third-party applications often create additional load, which can cause FPS to drop in games while recording.
The table below shows the key differences between a native solution and a typical third-party application:
| Characteristics | Built-in recorder | Third-party annex |
|---|---|---|
| Access to system sound | Complete (at the OS level) | Limited (depending on Android) |
| Impact on FPS | Minimum | Medium or high |
| Advertising | Absent. | Often present. |
| Drawing function | Limited. | Expanded |
💡
For daily use and recording games, Xiaomi’s built-in tool is the best choice due to its lack of advertising and better optimization.
Where records are stored and how to manage them
All the videos you create are automatically saved to the device's gallery, and by default, they end up in a separate album called Screen Records or Screen Recorder, which allows you to quickly find the content you want without going through thousands of photos in the shared tape.
Files are saved in format MP4, It's compatible with the vast majority of video players and social media, and the path to files in a file system is usually like /MIUI/screen_recorder/ or /DCIM/ScreenRecorder/, What to know when connecting your phone to your computer for fast file transfer.
Inside the Screen Recording app itself, you can find a folder that displays the save path in the settings menu, and a Clean button that allows you to delete all old records with a single click, and cleaning this section regularly will help free up space, since high-resolution videos take up a significant amount of memory.
⚠️ Note: Do not delete the system folder screen_recorder It can be used manually through the file manager if you are not sure what you are doing, and this can cause the application to reset or make errors when you try to write it again.
