Modern Xiaomi smartphones, which run on MIUI or HyperOS shells, have powerful built-in functionality that often goes unnoticed by ordinary users. One of these tools is a system screencaster that allows you to capture what is happening on the display without installing third-party applications, which is indispensable for creating training materials, recording the passage of games or saving rare errors in the system.
Unlike third-party solutions, the standard application does not require additional permissions and does not load the processor with background services. The quality of the recording depends on the selected resolution and bitrate settings, which can be flexibly adjusted to specific needs. The user gets full control over the sound sources, including the ability to capture the internal audio system or voice through the microphone.
In this guide, we will take a look at all aspects of screen video, how to activate hidden features, adjust quality settings for YouTube or social networks, and how to solve typical audio-free problems. We will look at the nuances of working with different versions of firmware and provide you with the knowledge to professionally record content.
Activation and configuration of the system recorder
To get started, you need to make sure that the feature is activated in the system. In most current versions of MIUI 12, 13, 14 and HyperOS, the tool is pre-installed by default. Open the swipe control menu from top to bottom and find the Screen Recorder icon or Screen Recorder. If the icon is missing, click on the edit button (usually in the form of a pencil or a tripole) and drag the module to the active panel.
Once you activate the widget in the curtain, click on it to run. Before you start recording, the system will suggest selecting parameters. Video resolution is a key parameter: 720p is enough for publishing in instant messengers, whereas for video hosting, you should choose 1080p or 4K if the device supports. High resolution greatly increases the size of the final file.
An important step is to adjust the audio stream. In the recorder settings menu, select the sound source. System sounds capture audio from applications (music, game sounds), but can block input (calls). The microphone option will record your voice and environmental sounds, which is ideal for comments.
☑️ Pre-recording checks
💡
To record gameplay with minimal delay (lag frey), it is recommended to use background downloads and energy saving mode before the start of the recorder.
Extended parameters: bitrate, FPS and timer
Deep video stream tuning allows you to tailor the recording to any requirements. Frame rate (FPS) determines the smoothness of the video. The standard value is 30 fps, which is enough for interfaces and static content. For dynamic games and action scenes, you need to set 60 fps, which doubles the smoothness, but requires more CPU resources.
The bitrate parameter (data flow rate) directly affects the detail of the picture. At low bitrate, compression artifacts ("squares") can appear on rapidly changing images. For recording in 1080p resolution, the optimal value is from 12 Mbit / s to 20 Mbit / s. If you plan further editing and color correction, it makes sense to set maximum values.
The delayed start (timer) feature is extremely useful when you need to open a particular application or menu before you start fixing, set a delay of 3, 5 or 10 seconds in the recorder settings, which allows you to safely fold the control panel and take the right position in the game or program before automatically starting recording.

Working with sound: system audio and microphone
Audio track setup is the most difficult aspect of recording on Android due to platform security limitations. Starting with Android 10, direct capture of internal sound is allowed, but in some regions or versions of MIUI this feature may be limited.
Microphone mode allows you to record voice comments on top of videos. This is useful for creating tutorials. However, it should be noted that this mode will record all extraneous noise in the room. For pure sound, it is recommended to use a headset with an external microphone connected via a 3.5 mm connector or Bluetooth, although Bluetooth audio delay can dissynchronize audio and video.
There is also a combination mode, not available in all firmware, that mixes system sound and voice, and if your phone doesn't support simultaneous recording, you'll have to choose between the clean sound of the game or your comment, in which case the professionals use external voice recorders or mount the voice separately.
⚠️ Note: When the screen recording through the microphone is enabled, the sound of messenger notifications (Telegram, WhatsApp) can be heard by the audience. It is recommended to activate the Do Not Disturb mode before the session begins.
Additional tools: drawing and camera
Xiaomi's built-in recorder offers interactive tools that appear in a floating window while recording. Drawing allows lines, arrows and circles to be applied directly over the image in real time. It's an indispensable tool for creating training videos where you want to highlight a specific button or interface element.
The Camera feature (or Face in the Frame) adds a small window with the front camera broadcast over the main video, which creates the effect of the author's presence, so you can move this window around the screen, changing its size or hiding it for a while so as not to overlap important gameplay or interface details.
All the annotations and camera overlays are rendered on the fly and become part of the final video file. You can't delete the arrow once you've finished recording, so use the tools carefully. For complex projects, it's better to record clean video and add graphics when you post-process it on your computer.
Comparison of built-in recorder and third-party applications
There are dozens of screencast apps available on the Google Play Store, such as XRecorder, AZ Screen Recorder or Mobizen. However, Xiaomi’s system solution often outperforms them in optimization, with third-party programs requiring broad permissions, consuming more power, and may contain ads, which is unacceptable when recording professional content.
Below is a comparison table showing the differences between native tools and popular third-party counterparts:
| Parameter | MIUI System Recorder | Third-party annexes |
|---|---|---|
| Stability of work | High (systemic level) | Medium (depending on optimization) |
| Advertising | Absent. | It is often present in free versions. |
| Sound capture | Direct (Internal Audio) | Requires permits and may have a delay |
| Impact on FPS | Minimum | Noticeable decline in productivity |
| Functional | Basic + Drawing | Expanded (editing, streaming) |
Using third-party software makes sense only in one case: if you need specific features that are not in the runoff, for example, direct streaming on Twitch or built-in video editor.
💡
The system recorder works at the core level of the system, which ensures that there is no desynchronization of sound and video, which is difficult to achieve third-party applications.
Hidden recording via ADB for advanced users
For users who want maximum quality and no interface elements (time icons, batteries, recorder sticks), there is a method of recording via USB debugging. This method allows you to use the system utility screenrecord, which feeds raw stream directly into the file.
To implement the method, you need to turn on Developer Mode (7 times click on the build number in "About Phone") and activate Debugging via USB. Then connect the phone to a PC with Android SDK Platform Tools installed. The command to start recording is as follows:
adb shell screenrecord --verbose /sdcard/demo.mp4This method allows you to set precise bitrate and duration parameters that are not available in the GUI. However, it is worth remembering that this method does not record sound (neither system nor microphone) without using complex additional sound mixers, since the screenrecord utility by default works only with video stream.
⚠️ Attention: Recording through ADB It requires a constant cable connection or a wireless debugging setup, and interrupting the connection will damage the record file.
Frequent problems and ways to solve them
One common problem is that the black screen is used when recording protected content, and applications like Netflix, Disney+, or banking clients use DRM protection, which automatically replaces the image with a black square for security purposes, and it is impossible to get around it without root rights.
Another problem is that the frame rate (FPS) drops dramatically during play, because of overheating of the processor or a lack of RAM, so you can reduce the recording resolution to 720p, close the background applications, and if possible cool the device, and turn off visual effects in the developer settings.
If the record file is not playable or has artifacts, check the encoding format. MP4 is standard with the H.264 codec. If you chose exotic codecs or containers (for example, MKV or HEVC/H.265 on older devices), the player may not be able to decode.
Why did the sound disappear after the update?
Where records are stored and how to share them
All video files created are automatically stored in the device's internal memory: /internal_storage/DCIM/ScreenRecorder/ or /internal_storage/MIUI/screen_rec/ The files are also duplicated in the System Gallery in the album Screen Records".
For quick publication, you can use the "Share" function immediately after recording stops. The system will suggest sending a file via Mi Drop (now Xiaomi Share), Bluetooth, or uploading to cloud services. Given the large size of the high-resolution video, it is recommended to use a Wi-Fi connection to transfer files, so as not to waste mobile traffic.
Clean your records folder regularly. High-quality videos quickly take up space: one minute of recording in 4K 60fps can weigh more than 500MB. Use a built-in cleaner or file manager to remove failed takes and free up space for new projects.
