Creating screencasts has become an integral part of using modern smartphones, allowing users to record game moments, create educational videos or save important dialogues in instant messengers. For owners Samsung Galaxy M31 this task is solved as simply as possible thanks to the built-in software that does not require the installation of third-party utilities. The built-in tool provides high picture quality and flexible adjustment of audio parameters, which makes the process of capturing content convenient and intuitive even for beginners.
However, many users are still looking for ways to activate this function, since the icon may be hidden in the depths of the menu or not on the visible part of the notification panel. Understanding the logic of the interface One UI allows you to quickly find the desired switch and start recording with one touch. Below we will analyze in detail all the setup steps, the nuances of working with sound and possible problems that you may encounter when using a standard recorder.
Activating the function through the quick settings panel
The fastest way to start recording what is happening on the display is to use the notification curtain. In the operating system Androidinstalled on your device, this control is brought to the surface for instant access. To use it, just swipe your finger from the very top edge of the screen down, thereby opening the quick access panel.
If you don’t see an icon called “Screen Recording” among the first icons, don’t rush to panic. The interface One UI allows you to hide rarely used buttons on the second page of the panel. You'll need to swipe again or tap the edit button (usually a pencil icon or three dots) to expand the full list of available toggles.
Find the tile that says Screen recording and drag it to the active area of the notification panel. Now the function will always be at hand. After you click on this icon, the system will ask for permission to access multimedia and files on the device - this is a standard security procedure Androidwhich must be confirmed with the "Allow" button.

Configuring recording parameters and video quality
Before the actual image capture process begins, a pop-up menu with settings will appear on the screen. Here you can determine the technical characteristics of the future video file. The quality of the picture directly affects the file size and the load on the processor Exynos 9611with which yours is equipped. Samsung M31.
In the settings menu you will be asked to select a resolution. Options available from low quality to Full HD. For most tasks, such as recording gameplay or demonstrating how applications work, the resolution 1080pwould be the optimal choice. This will ensure image clarity without excessive consumption of free space in the internal memory.
The audio format is also adjusted here. You can choose to record only system sounds (what you hear from the speakers), only microphone audio (your voice and sounds around you), or a combination of both sources. If you plan to comment on what is happening, be sure to select the mode Microphone or System sounds and microphone.
| Parameter | Description | Recommendation |
|---|---|---|
| Resolution | Image detail (SD, HD, Full HD) | Full HD (1080p) for clarity |
| Sound | Source audio stream | Microphone for comments |
| Show touches | Display touch points on the screen | Enable for training videos |
| Front camera | Adding video from a selfie camera | Disable to save resources |
If you are recording a video for YouTube or social networks, choose the highest available resolution, as platforms often compress content and a quality margin will be useful.
Recording process and widget management
After confirming the settings, the countdown will begin and a floating control panel will appear on the screen. This small button allows you to control the process without having to lower the notification shade every time. It can be moved to any part of the screen so as not to block important elements of the application or game interface.
The floating panel contains the main control buttons: pause, end recording and switch the camera. The pause feature is especially useful if you need to take a break, hide private messages, or switch to another application without unnecessary content ending up in the final video. Click the pause button to pause the timer and resume recording when you're ready.
To complete the process, just click the red stop button on the widget or notification panel. The system will automatically save the file to the gallery.
⚠️ Attention: When recording high graphics games on Samsung M31 there may be a slight decrease in performance or heating of the case, as the processor simultaneously processes graphics and encodes video.
Working with sound and microphone
One of the most common questions concerns how to record the internal sound of an application along with the voice. In earlier versions Android this was not possible without root access, but modern updates One UI fully support mixing audio streams. If you select the appropriate setting in the menu before starting, the phone will capture both channels.
If you choose to record only system sound, viewers will hear music from the game or notification sounds, but your voice will remain behind the scenes. This is ideal for creating clean gameplay cuts. In contrast, Microphone Only mode will mute system sounds, leaving only your commentary, which can be useful for narrating slide shows or instructions.
The sensitivity level of the microphone depends on how close you hold the phone to your mouth. For high-quality voice acting, it is recommended to use a headset with a built-in microphone, connected via connector 3.5 mm or via Bluetooth. This will separate the voice from the noise emitted by the smartphone itself when the processor operates.
Why is there no sound in the recording?
If there is no sound in the final video, check the media volume settings during recording. Also make sure that the application you are recording does not block audio capture (some banking applications and streaming services block audio recording for security reasons).
Where recordings are saved and how to find them
All created screencasts are automatically saved in the device’s internal storage. You can find them through the standard application Gallery. The system creates a separate album called "Screen recordings" or "Screen recordings", where the files are sorted by creation date. This simplifies navigation if you have accumulated a lot of video materials.
The physical path to the files in the file system looks like Internal Storage/DCIM/Screen recordings. Knowing this path, you can easily transfer videos to your computer via a USB cable or send them to cloud storage. The default saving format is MP4, which is compatible with most video players and social networks.
The amount of space occupied depends on the recording duration and the selected resolution. A minute of video in resolution 1080p can take from 50 to 100 megabytes. Regularly check the free space in the section Settings → Device maintenance → Storageto avoid a situation where recording is interrupted due to lack of space.
⚠️ Attention: Some applications, such as Netflix, Disney+ or banking clients, use DRM protection. When you try to record the screen in such apps, you will get a black screen instead of an image, and this is a normal security operation and not an error.
Screen recording files take up a significant amount of memory, so it is recommended to periodically transfer them to your computer or delete unsuccessful takes.
Fixing common problems and restrictions
Sometimes users are faced with a situation where the record button is inactive or the recording is interrupted spontaneously. Most often this is due to energy savings or background system limitations. Make sure that the Screen Recorder application (if it appears in the list of applications) or the system as a whole does not have strict limits on background work.
Another reason for failures may be overheating of the device. Samsung Galaxy M31 has passive cooling, and during prolonged use (game + video recording), the case temperature may increase. In this case, the system will forcefully lower the screen brightness or close resource-intensive processes, including recording, to protect components.
If the video quality seems blurry or jerky, try lowering the resolution in the settings before starting recording. Also check if the power saving mode is enabled, which limits the frame rate and processor performance. For stable recording, it is better to use the mode High performance or disable battery saving.
Is it possible to record calls?
The standard screen recording function is not intended for recording telephone conversations due to legal restrictions and technical blocking of access to audio channel in many regions. This requires specialized call recorder applications.
Additional features and tips
In addition to basic recording, the control panel offers the function of adding images from the front camera. This creates a picture-in-picture effect where your face is displayed in a small window on top of the main content. You can change the size and position of this window in real time by dragging it with your finger.
The Show Touches feature is useful for creating instructions. It visualizes where you click on the screen with white circles, which helps the viewer understand where exactly you click in the interface. However, in artistic videos or gameplay, this option can be distracting, so it is better to disable it.
Don't forget that after recording a video, you can immediately edit it using the built-in gallery tools. You can trim the beginning and end where you adjusted the settings, apply filters, or add music. This saves time and eliminates the need to use third-party video editors for simple processing.
⚠️ Attention: The interface and available settings may vary slightly depending on the installed firmware version One UI. If you do not find the described items, check for software updates in your phone settings.
Use airplane mode when recording gameplay so that incoming notifications and messages do not cover the screen and spoil the frame, but do not forget to download the necessary content in advance if it requires the Internet.
Why does screen recording stop on its own? in a few minutes?
Most often this happens due to a lack of free RAM or processor overheating. The system forcibly closes heavy tasks for stability. Try closing all background applications before starting recording and lowering the video resolution.
Is it possible to record the screen with the display turned off?
No, the standard screen recording function on Samsung M31 requires that the display be turned on. If the screen goes dark (goes to sleep), recording will automatically pause or end. For long-term recording of audio without an image, it is better to use a voice recorder.
Where can I find the microphone settings for recording?
Microphone settings are selected not in the general settings of the phone, but in the pop-up menu that appears immediately after clicking on the "Screen Record" icon in the notification shade, just before the process starts.
Is audio recorded from headphones?
Yes, if you use wired or Bluetooth headphones, system audio will be recorded directly from the device. If the microphone recording mode is selected, the phone will record what its built-in microphone hears, including the sound coming from the headphones if it leaks out.
How to remove the floating button from recording?
The floating control panel disappears automatically if you minimize it to a small dot. To completely hide the controls while recording, you can drag the panel to the edge of the screen, where it will collapse into a minimal indicator that does not overlap the content.
