This is the basic stage on which the stability of the connection and the quality of data transfer depend. Make sure your phone has the latest firmware, accessible through the update menu.
The quality of your Internet connection is a critical parameter. To work with a video stream in real time, a stable communication channel is required. It is recommended to use a Wi-Fi network with a frequency of 5 GHz if the router supports this standard, as it provides lower latency compared to 2.4 GHz.
It is also worth checking the energy saving settings. Aggressive battery saving modes may forcefully close background processes of the Yandex application, which will lead to a loss of connection with the camera. Disable battery optimization for this application in the system settings.
- 📱 Make sure that the version of Android on your device is at least 10.0 for modern security protocols to work correctly.
- 🔋 Disable the "Maximum energy saving" mode during the initial setup of devices.
- 📶 Check the speed Internet: the minimum speed of the incoming stream must be at least 5 Mbit/s.
Installation and initial setup of the Yandex application
The central control element is the official application. It must be downloaded exclusively from a trusted source, which for Samsung users is the store Galaxy Store or Google Play. Using third-party APK files may lead to leakage of personal data or failure of smart home functions.
After installation, launch the application and log in to your account Yandex ID. If you don't yet have an account, the registration process will only take a few minutes and will require you to enter your phone number. This account will be the link between your smartphone and the smart camera.
During the first login, the system may request permission to send notifications. This is critically important for the video surveillance function, since it is through push notifications that you will receive signals about movement or sound in the camera’s field of view. Do not ignore this request.
Path to check permissions: Settings → Applications → Yandex → Notifications → AllowThe application interface is intuitive, but you should pay attention to the "Devices" tab. This is where the status of your camera will be displayed after successful pairing. If the tab is empty, it means that the procedure for adding a device has not yet been completed.
When logging into your account, enable two-factor authentication. This will protect access to your camera from unauthorized entry even in the event of a password leak.
The process of connecting a Yandex smart camera to a smartphone
The process of adding a camera to the Yandex ecosystem requires careful attention. Usually the device comes with a QR code on the case or in the instructions. You need to press the "+" button in the application and select the device type "Camera".
Next follow the instructions on the screen. The application will ask you to scan the QR code. Point your camera Samsung A51 at the code so that it fits completely within the scanner frame. After successful reading, the process of searching for the device on the network will begin.
At this stage, the phone may offer to connect to a temporary Wi-Fi network, which is distributed by the camera itself. This is standard procedure for transferring your home network information to the device. Confirm the connection and wait until the setup is completed.
| Setting stage | User action | Status indicator |
|---|---|---|
| Scanning | Pointing the camera at the QR code | Camera sound signal |
| Pairing | Confirmation of connection to the temporary network | Flashing indicator on the camera |
| Configuration | Selecting a name and room | Continuous light of the indicator |
| Finalization | Check video stream | Displaying a picture in the application |
After the camera appears in the list of devices, you can click on it to view the video stream. The quality of the picture depends on the speed of your Internet and the settings of the camera itself. If necessary, you can switch the resolution in the device settings inside the application.
What to do if the camera is not located?
Make sure you are close to the camera and router. Try resetting the camera to factory settings by holding the reset button for 10 seconds and repeat the connection procedure again.
Setting up notifications and security scenarios
The functionality of a smart camera is not limited to viewing. The greatest value is the notification system. In the Yandex application, you can adjust the sensitivity of motion and sound sensors. This allows you to avoid false alarms, for example, from cars passing outside the window.
Go to the settings of a specific camera and find the “Sensors” section. Here you can set the sensitivity level to “High”, “Medium” or “Low”. For an apartment in a noisy area, the optimal choice is often a medium level that filters out background noise.
The “Face Detection” or “Sound Recognition” function (for example, a crying child or a barking dog) is also available. These functions use artificial intelligence algorithms on Yandex servers and require an active Internet connection. Enabling these options may affect the system's response speed.
- 🔊 Turn on the "Sound when motion is detected" option if you want the camera to emit a warning signal.
- 🌙 Set the "Night" mode to automatically turn on the infrared illumination at night.
- 💾 Activate cloud storage if you want to save event history for longer than allows a local memory card.
⚠️ Attention: Using facial recognition functions and permanent recording to the cloud may require a paid Yandex Plus subscription with the Smart Home option. Check the tariff conditions in your personal account before activating advanced features.

Advanced functions for creating screenshots and processing them
Samsung smartphones are famous for their advanced software for working with images. After taking a screenshot, you have a few seconds to use the panel that appears at the bottom of the screen. The "Scroll" button (downward arrow icon) is available here.
Clicking on this button allows you to take a long screenshot. This is indispensable if you need to save correspondence in the messenger, a long article in the browser, or the entire Yandex application settings. The phone will automatically scroll the page down, adding new areas to the image.
There is also a pencil icon on the toolbar for quick editing. You can trim off the excess, add text, highlight an important element with a marker, or draw an arrow. All changes are saved automatically when you click the "Done" button or the save icon.

The Volume Down + Lock key combination is the most reliable method, working in 100% of applications, while palm swipe may not work in games or when scrolling quickly.
Managing files and optimizing memory after creation snapshots
All created screenshots are automatically saved to a folder DCIM/Screenshots in the internal memory of the device. Over time, this folder can grow, taking up valuable disk space Samsung A51, especially if you actively take long screenshots.
It is recommended to regularly audit these files. The Gallery app includes a Screenshots album where you can quickly view all your saved images. Delete unnecessary items immediately so as not to clog up your memory.
If you use screenshots for work or school, set up automatic synchronization with a cloud service, for example, Yandex.Disk or Google Photos. This will free up space on your phone, leaving access to the archive of pictures at any time.
To clear space, you can use the built-in Device Maintenance tool. It will find duplicate images and offer to delete blurry or similar pictures, which is important if you frequently use the screen burst function.
Why is the screenshot saved in low quality?
Usually screenshots are saved in the native screen resolution. If the quality seems low, check to see if the Gallery app has a space-saving display mode enabled. Also make sure that you did not reduce the image when editing before saving.
Can I take a screenshot in safety mode?
In Safe Mode, third-party applications are disabled, but the system function of creating screenshots through buttons should work. However, palm swiping may not function if touch screen drivers in this mode operate in a simplified version.
How to disable the shutter sound when taking a screenshot?
On global firmware versions, the screenshot sound is tied to the general volume level of the media or system. You can disable it completely by putting your phone on silent or vibrate mode before taking a photo.
Where can I find my screenshot history if I accidentally deleted an album?
Albums in Samsung Gallery are simply representations of folders. If you deleted an album, the files themselves could remain in the folder through the “My Files” file manager along the path Internal memory → DCIM → Screenshots. Also check the trash can in the Gallery application, files are stored there for 30 days.
Does taking a screenshot affect the performance of the Yandex camera?
No, these processes are independent. Taking a screenshot is a local framebuffer write operation that takes milliseconds and does not load the processor enough to interrupt the video stream from the network. A delay can only occur if the Wi-Fi signal is extremely weak.
