With the transition to the operating system version Android 9 Pie, many users have encountered changes in the interface and functionality of the device. One of the most popular features that smartphone owners often look for is the ability to capture what is happening on the display. This is necessary to create training videos, save game moments, or demonstrate errors in applications. However, unlike newer versions, “pure” Android 9 does not always have an obvious button to start recording in the notification shade.
In this article we will analyze in detail all the available methods that allow you to create a high-quality screencast on your device. We will look at both standard features hidden in the depths of the settings, and time-tested third-party solutions. We will pay special attention to the nuances of sound capture and the impact of the recording process on the performance of the gadget.
Before you start installing additional software, you should make sure that the manufacturer of your smartphone has not implemented this function in the shell. Various skins from Samsung, Xiaomi or Huawei may have their own implementations that differ from the stock experience. Understanding the architecture of your system will help you choose the most efficient and secure path.
Checking the built-in capabilities of the system
The first step should always be a thorough check of the standard interface. In some firmware based Android 9 the screen recording function is already integrated, but hidden in the quick settings menu. To find it, pull the notification shade all the way down and look for the tile editing button, usually located in the lower left corner or indicated by a pencil icon.
In the icon drag menu that opens, look for a tile called “Screen Recorder” or “Screen Recorder.” If you find such an element, simply drag it to the active area of the curtain. After that, when you swipe from above, you can activate the recording with one click. This is the most preferable option, since it does not require the installation of unnecessary software.
It is worth considering that even if there is a button, the functionality may be limited. Standard recorders often do not allow you to select the bitrate or resolution manually, working in automatic mode. In addition, some implementations do not have the ability to record the internal sound of the system, which is critical for gamers.
⚠️ Attention: The presence of a record button in the curtain does not guarantee its operation in all applications. Banking apps and services with protected content (DRM) can block image capture, resulting in a black screen on the final video.
Using specialized applications
If system tools are missing or their functionality is not for you satisfied, applications from the store come to the rescue Google Play. Today, there are many powerful tools that can bypass the limitations of the stock system. When choosing a app, pay attention to the presence of advertising, the ability to record sound from a microphone and internal audio.
One of the leaders in this niche is the application XRecorder or ADV Screen Recorder. They offer flexible quality settings, including choice of resolution 1080p or 720p, as well as frame rate. High FPS (frames per second) is critical for smooth images in fast-paced games and interface animations.
The setup process is usually intuitive. Once installed, you will need to give the app permission to display on top of other windows and access storage. Modern recorders can also draw on the screen in real time, which is convenient for creating educational content.
- 🎥 AZ Screen Recorder: A classic solution with streaming support and no recording time restrictions.
- 🎙️ DU Recorder: It features a built-in video editor and the ability to record high quality audio.
- 🛠️ Screen Recorder - No Ads: A lightweight application without intrusive advertising, ideal for older users devices.
Otherwise, the system may forcefully terminate the recording process to save energy.
Before starting a long recording, clear the RAM of unnecessary applications - this will prevent possible freezes and ensure smooth video.
Adjusting quality and sound parameters
The quality of the final video directly depends on the selected encoding parameters. In the settings of most applications you will find a section responsible for the video stream. The key parameter here is bitrate, which is measured in megabits per second (Mbps). The higher this value, the clearer the picture, but the greater the weight of the file.
To record gameplay on Android 9, it is recommended to set the bitrate to at least 12 Mbps at Full HD resolution. If your goal is to record static instructions or work with text, you can reduce the value to 6-8 Mbps, which will significantly save storage space. It is better to keep the frame rate at 60 fps for dynamics or 30 fps for normal tasks.
The audio track setting deserves special attention. On Android 9, capturing internal audio (system sounds) often requires rooting or using special methods via ADB, as Google has restricted direct access to the audio stream for security reasons. In most cases, the application will record sound through the microphone, picking it up from the speaker.
| Parameter | Recommended value (Games) | Recommended value (Instructions) | Impact on file |
|---|---|---|---|
| Resolution | 1920x1080 (Native) | 1280x720 | High/Medium |
| Bitrate | 12-16 Mbps | 6-8 Mbps | Direct impact on size |
| Frame rate | 60 fps | 30 fps | Affects smoothness |
| Codec | H.264 | H.264 | Compatibility |
The balance between picture quality and file size is achieved by experimentally selecting the bitrate for a specific task.
Recording via computer using ADB
For advanced users who require maximum quality without loading the smartphone processor, The ideal option would be to use the utility ADB (Android Debug Bridge). This method allows you to broadcast the image from the screen to a computer and record it there using the power of the PC. This method is especially relevant for devices with weak hardware.
To get started, you need to activate developer mode on your phone. Go to Settings → About phone and quickly click on “Build number” seven times. After this, a new section “For Developers” will appear in the settings menu, where you need to enable USB debugging.
Connect your smartphone to the computer with a cable and open the command line on the PC in the folder with ADB installed. Enter the command to test the connection:
adb devicesA request for debugging permission will appear on the phone screen, which must be confirmed. After successful pairing, you can use the command to capture video. However, it is worth noting that direct recording to a file via ADB on Android 9 may be limited, so a combination with the utility is often used scrcpy.
⚠️ Attention: Using ADB requires installed device drivers on the computer. Without them, the computer will not see the smartphone in debug mode.
Command for recording via scrcpy
After installing scrcpy, just run the app and press Win+Alt+R to start recording video from the screen in mp4 format. This ensures minimal latency and high quality.
Hidden functions and engineering menus
Some manufacturers leave hidden testing capabilities in the system, which may include screen recording functions. They are often accessed through the engineering menu or special codes in the dialer. However, using these methods requires caution, since changing the settings incorrectly can lead to unstable system operation.
On devices with processors MediaTek or Qualcomm sometimes there are hidden settings in the developer menu. Try looking for items related to “Demo Mode” or “Screen Recording”. Activating such functions can unlock a system recorder that was previously hidden from the user.
It is also possible to use commands through the terminal on the device itself if it has superuser rights (Root). The command screenrecord in the terminal allows you to record video directly to storage, bypassing the graphical interface of applications.
adb shell screenrecord --verbose --size 1280x720 --time-limit 180 /sdcard/demo.mp4This method gives a clean signal without overlaying the recorder interface, but requires knowledge of the command line syntax. Recording is stopped using a key combination Ctrl+C in the terminal or after a set time limit has expired.
☑️ Preparing for recording via ADB
Optimization and problem solving
In the process of recording video from the screen to Android 9 users may encounter a number of problems such as audio and video desynchronization, device overheating, or a sharp drop in gaming performance. Most often, the reason lies in the lack of processor resources, which simultaneously renders graphics and encodes the video stream.
To minimize the load, close all background applications before starting recording. Disable unnecessary synchronization services and reduce screen brightness. If the performance problem persists, try reducing the recording resolution or frame rate in the settings of the recorder application.
The problem of no sound is often solved by switching the audio source in the application settings from “Microphone” to “Internal Audio”, if this is supported by the OS version and the specific device. Otherwise, for the purity of the experiment, increase the media volume to maximum and ensure silence in the room.
⚠️ Attention: Interfaces and capabilities may vary depending on the specific smartphone model and firmware version. Always check the settings with the official documentation of your device manufacturer.
Regularly clearing the recording application cache also helps avoid file saving errors. If your video stops mid-sentence, check your internal storage for free space, as high-quality files take up a lot of space.
Why is video recorded without sound?
With Android 9, Google has introduced strict restrictions on internal audio capture to protect privacy. Most applications can only record audio through a microphone. Recording system audio often requires root access or the use of special patches.
Is it possible to record video in games with protection?
No, many modern games use security flags (FLAG_SECURE), which prohibit the creation of screenshots and video recordings at the system level. When you try to record, you will get a black screen.
Where are the files saved after recording?
By default, videos are saved in the folder DCIM/Screencasts or in the root of the internal memory in the folder with the name of the recorder application. The path can be changed in the settings of the application itself.
Does recording affect the battery?
Yes, the video encoding process is a resource-intensive task and leads to increased battery consumption, and can also cause heating of the smartphone case.
