Modern Samsung Galaxy smartphones are powerful multimedia centers capable of not only reproducing content, but also creating it professionally. Screen recording, which previously required installing disreputable third-party apps, is now built right into One UI. This allows users to quickly capture gaming moments, create training videos, or save important conversations without losing quality.
However, despite the obviousness of the function, many device owners have difficulty setting up the audio track. It often happens that video is recorded, but there is no sound, or only the owner’s voice is heard, and system notifications remain silent. In this article we will look in detail at how to activate built-in recorder, set up audio capture from different sources and avoid common mistakes when creating screencasts.
The correct configuration of parameters before starting recording is critical to obtaining a high-quality result. We will look at the nuances of the microphone and internal audio, and also discuss what restrictions the operating system Android imposes on different types of applications. Understanding these mechanisms will help you avoid situations where, instead of the expected video, you get a silent video.
Activating the built-in screen recording tool
The first step to get started is to add the corresponding button to the quick settings panel. On smartphones Samsung Galaxy this function is hidden by default in the extended menu so as not to clutter the main interface. You need to swipe down twice to reveal the entire list of available switches and find the video camera icon or the Screen Recording icon.
If you don’t find the item you need right away, scroll to the bottom of the list and click on the pencil icon or the “Edit” button. In the editor that opens, drag the recording icon to the active zone. This action will only take a few seconds, but will give you instant access to the function at any time. Once added, the button will be available in the top notification shade.
It is worth noting that the arrangement of elements may vary slightly depending on the firmware version One UI. On older models, such as Galaxy S8 or Note 9, the interface may look different, but the operating logic remains the same. Once the button is added, you're ready to customize your capture settings.
If you use screen recording frequently, place the button in the top row of the notification bar for the fastest possible access without unnecessary swipes.
Setting up audio sources for ideal quality
The most important step in determining the success of your recording is choosing the right source sound. When you press the record button, the system will prompt you to choose one of three modes. This choice directly determines what exactly will be heard in the final video. An incorrect setting will result in viewers not hearing either the game effects or your commentary.
The mode Media is designed to capture the internal sound of the device. It's ideal for recording gameplay, watching videos, or demonstrating how apps work. In this mode, the microphone is turned off, and only sounds produced by the smartphone itself are recorded. The quality of such audio will be crystal clear, without extraneous noise and echo.
If your goal is to create a video lesson with voice accompaniment or record a video call, you will need the Media and microphonemode. In this case, the system mixes the internal sound and your voice. However, it is worth considering that when using speakers, the sound from them may partially fall into the microphone, creating an echo effect. To minimize this effect, it is recommended to use headphones.
⚠️ Attention: Microphone Only mode completely disables system audio capture. Use it only if you need to record silence or sounds exclusively from the external environment, ignoring what is happening on the screen.
Technical limitations Android prevent some applications from sending audio to the internal recorder. This is due to privacy policy and copyright protection. For example, when trying to record a conversation in instant messengers like WhatsApp or Telegram, the interlocutor may not be heard in media capture mode. In such cases, the only way out is to use a microphone and speakers at a maximum volume that does not distort the sound.
Step-by-step guide for starting recording
After all the settings have been checked, you can begin the actual recording process. The algorithm is simple, but requires attention to detail, especially if you are recording dynamic content. Any unnecessary touch on the screen can ruin the frame, so it is better to prepare the script in advance.
Follow the following steps to start the process:
- 📱 Open the application or game that you plan to record and prepare the desired frame.
- 🔽 Swipe down from top to open the quick settings panel and find the button "Screen Recording".
- 🎙️ In the pop-up window that appears, select the desired audio source (Media, Microphone or Both).
- ▶️ Click the "Start Recording" button and wait for the countdown (usually 3 seconds).
While recording, a small floating panel will appear on the screen management. It allows you to pause the process, take a screenshot of the current frame, or enable drawing on the screen, which is useful for creating educational materials. To end recording, just press the stop button on this panel or in the notification shade.
☑️ Preparing for recording
The finished file will be automatically saved in the device gallery. The system assigns files names with the date and time of creation, which simplifies sorting. You can immediately open the video, edit it in the built-in editor, or share it with friends via instant messengers.
Advanced settings and video parameters
For advanced users who need to control the file size and picture quality, advanced recorder settings are available. They are located in the settings menu of the recording application itself, which can be accessed by clicking on the three dots next to the function button or through the general phone settings.
Here you can change the video resolution. The default is usually set to a value that matches your screen resolution, for example 2400×1080 for modern flagships. Reducing the resolution to HD (1280×720) will help significantly reduce the file size if you plan to send video over the Internet.
Adjusting the frame rate is also available. The standard value is 30 frames per second, which provides a smooth picture for most tasks. If you record dynamic games, you can try setting 60 frames per second, but this will increase the processor load and the size of the final file.
| Parameter | Recommended value | Impact on the result |
|---|---|---|
| Resolution | Full HD (1080p) | Balance of quality and size |
| Frame rate | 30 fps | Standard smoothness |
| Format | MP4 | Maximum compatibility |
| Sound | AAC | Good quality with low weight |
Hidden drawing capabilities
During recording, you can turn on the drawing mode to highlight important elements on the screen with a cursor or arrows in real time.
Solving problems with sound and black screen
Sometimes users are faced with a situation where a video is recorded, but there is no sound, or a black screen is visible instead of an image. This is often due to security restrictions Androidthat block the capture of protected content (DRM). Applications like Netflix, YouTube Premium or banking apps can block screen recording at the system level.
If you are recording a game or a regular application and there is no sound, check if Do Not Disturb mode is turned on. In some configurations, this mode may drown out system sounds that the recorder is trying to capture. Also make sure that the media volume is not turned down to zero, since internal capture depends on the signal level in the system.
The black screen problem is often solved by updating the application or system. If this happens in a specific application, most likely the developer has prohibited screenshots and recording for security purposes. It is impossible to bypass this limitation using standard means without obtaining root access, which is not recommended for ordinary users.
⚠️ Attention: Interfaces and names of menu items may differ depending on the version of One UI and the model of your Samsung smartphone. If you do not find the described setting, check the "Accessibility" section in the general settings.
Saving and editing recorded material
After recording is completed, the file goes to the standard "Gallery" application in the "Screen recordings" or "Screen recordings" album. Samsung's built-in editor allows you to perform basic video processing directly on your phone without installing additional software. This saves time and allows you to quickly prepare content for publication.
You can trim the beginning and end of the post, removing extra seconds of preparation. There's also a tool available to add music or change the audio track if you forget to turn on the microphone while recording. For more complex editing, for example, adding transitions or titles, it is better to use specialized applications from Google Play.
Do not forget to periodically empty the folder with recordings, since video files take up a significant amount of memory. One minute of high-resolution recording can weigh between 50 and 100 megabytes. Regularly transferring important files to your computer or cloud storage will help avoid running out of space on your device.
Samsung's built-in gallery editor allows you to trim the video and change the cover, but to add a voice over the finished video, it is better to use third-party video editors.
Why is there no sound from applications when recording a video?
This is related with Android security restrictions. Some applications (messengers, banking services) block internal audio capture to protect privacy. In such cases, only recording via a microphone works.
Is it possible to record the screen with the display turned off?
No, the standard Samsung recorder requires the screen to be turned on. If the screen goes dark, recording will automatically stop or pause. To record with the screen turned off, special utilities with root access is required.
Where are the screen recording files stored?
The files are saved in the internal memory in the folder DCIM/ScreenRecords or in the "Screen Recordings" album in the Gallery application. The path may vary slightly depending on the firmware version.
How to record a video with the sound of a call?
It is impossible to record a conversation during a regular phone call using standard means due to strict confidentiality restrictions. Third-party applications are also often blocked by the system on new versions of Android.
Does screen recording affect game performance?
Yes, video recording creates additional load on the processor and graphics chip. In heavy games, this may lead to a slight decrease in FPS (frames per second) or increased heating of the device.
