In today's digital world, QR codes have become the universal key to fast data transfer, whether connecting to Wi-Fi, paying in a store, or going to a website. Device owners Samsung often look for the fastest way to read such code without installing unnecessary apps. Fortunately, the operating system Android in conjunction with the shell One UI from the Korean giant provides powerful tools for this right out of the box.
Previously, users had to download specialized scanner applications, which often overloaded the system with advertising. Today the situation has changed dramatically: image recognition algorithms are built deep into the system. Samsung camera automatically recognizes QR codes without the need to press additional buttons if this function is activated in the settings. This makes the process instant and intuitive even for beginners.
In this article we will analyze in detail all available methods scanning on smartphones Samsung Galaxy. You will learn how to set up automatic recognition, use a voice assistant Bixby and what to do if a standard camera does not see the code. We will also touch on security issues, since not all links in the codes are safe.
Using the built-in scanning function in the Camera application
The most obvious and fastest way is to use the standard application Camera. In the latest versions of the shell One UI (starting from version 2.0 and higher, relevant for models of the S, A, M and Note series), the recognition algorithm works in the background. You don't need to look for a separate "Scanner" button in the shooting interface.
Just point the lens at the code image. The system will automatically detect the presence of a graphic marker and offer a pop-up notification or link directly on the viewfinder screen. However, if this does not happen, the function may be disabled in the settings of the application itself.
To activate, open the application Camera and click on the gear icon in the upper left corner. In the menu that opens, find the item Scan QR codes and make sure that the switch is lit blue. Here you can also configure the action after scanning: open the link immediately or show a preview.
⚠️ Attention: Do not follow links from unknown QR codes without first checking. Attackers can create fake codes that lead to phishing sites that disguise themselves as pages of banks or popular services.
It is important to understand the difference between regular scanning and mode Super Resolution. If the code is printed very small or is located far away, the standard mode may not cope. In such cases, optical zoom or switching to the “Pro” mode will help, although for most everyday tasks the automatic mode is sufficient.
Setting up and using Bixby Vision
For those who prefer more advanced image analysis functions, the company Samsung integrated technology Bixby Vision. This is not just a code scanner, but a full-fledged augmented reality engine that can translate text, select objects and search for goods.
To activate this mode, launch the application Camera and in the bottom menu select the item Bixby Vision (sometimes it may be simply called “Search” or have an eye/lens icon). The interface will change and a focus frame will appear in the center.
Unlike quick scanning, Bixby Vision
requires confirmation of the action. After pointing at the code, the system will offer options for action: open the link, save the contact, or show the product in stores. This is convenient when you scan a code from a product in a store and want to compare prices.- 🔍 Deep analysis: Bixby does not just read the link, but can also show information about the product or place.
- 🌐 Real-time translation: If the QR code contains text in a foreign language, Bixby can immediately translate it into Russian.
- 🛒 Product search: Ideal for shopping, allowing you to instantly find a product on the Internet by image or code.
It is worth noting that for work Bixby Vision requires a stable Internet connection, since image processing often occurs on servers. If you are in an area with poor reception, it is better to use the standard camera mode, which works offline for basic links.
Alternative method: Google Lens and Google Lens
If for some reason standard tools Samsung do not suit you or do not work correctly, you can always resort to the help of the ecosystem Google. Any smartphone with Android has a pre-installed service Google Lens (Lens), which is one of the most powerful computer vision tools.
You can launch it in several ways. The simplest is through the search bar widget Google on the main screen. Click on the small colored camera icon to the right of the search bar. Also Google Lens is often built into the application Google Photos or accessible through the Google widget.
Interface Google Lens is designed for versatility. It automatically detects what is in front of the camera: text, plant, animal or QR code. When you hover over a code, the system will highlight it with a frame and offer to follow the link. The accuracy of recognizing damaged or flooded codes from Google is often higher than that of stock solutions.
☑️ Checking camera settings
Another advantage Google Lens is the scan history. Unlike a standard camera Samsungwhich may not save your browsing history, your Google Account saves your activity. This allows you to return to a previously scanned link if you accidentally closed the page.
Using widgets and quick settings panel
Shell One UI is famous for its flexibility in customizing the interface. If you need to scan codes constantly, reaching for the camera icon every time can be inconvenient. The solution to the problem is to move the scanning function to the main screen or to the notification panel.
On the desktop Samsung you can add a “QR code scanner” widget. To do this, make a long tap (press and hold) on an empty space on the desktop, select the item Widgets and find it in the list QR code scanner. Drag it onto the screen. Now one tap on the widget will immediately launch the camera in scanning mode.
An alternative option for advanced users is to add a button to the quick settings panel (curtain). Lower the top curtain twice, click on the three dots in the corner or the edit button (usually a pencil). Find “QR code scanner” in the list of available buttons and drag it to the active zone.
This approach saves time and eliminates the need to unlock the phone and look for the application. This is especially true in situations where you need to quickly pay for a purchase at the checkout or present a pass.
What to do if the widget is not added?
If the widget is not added to the desktop, check if the device memory is full. Also, some launchers (third-party shells) can block Samsung system widgets. Try temporarily returning to the standard One UI Home screen.
Third-party applications from Google Play Market
Despite the power of the built-in tools, there are situations when specialized software is required. For example, if you need to scan codes of a certain format (Data Matrix, Aztec), save history to the cloud, or work without the Internet on an industrial scale.
There are thousands of scanner applications in the store. Market leaders are considered Google Play thousands of scanner applications. Market leaders are considered QR & Barcode Scanner from Gamma Play i Kaspersky QR Scanner. The latter are notable because they check the link for viruses before opening, which adds a layer of security.
When choosing a third-party application, pay attention to the permissions. The scanner only needs access to the camera. If an application requires access to contacts, microphone or geolocation without obvious need, this is a reason to be wary and refuse installation.
| Application | Security | Advertising | Functional |
|---|---|---|---|
| Samsung Camera | High | No | Basic |
| Google Lens | High | No | Advanced (search, translation) |
| Kaspersky QR | Maximum | No | Checking links for viruses |
| QR & Barcode Scanner | Average | Yes | History, creation of codes |
The use of third-party software is justified if you work with large volumes of data or need specific features such as batch scanning or export to Excel. For the average user, the built-in tools are more than enough.
Problem solving: what to do if the camera does not see the code
Sometimes users are faced with a situation where the camera simply ignores the QR code. This can be caused by several factors: from simple dirt on the lens to software glitches. The first step is always to wipe the camera with a soft cloth.
The second common reason is distance. Camera autofocus Samsung has a minimum focusing distance (usually 10 cm). If you bring the phone too close, the camera will not be able to “catch” the sharpness. Try moving the device a little away.
The problem may also lie in the lighting. Glare on the glossy surface of the code or too dim light prevents the algorithms from recognizing the contrasting pattern. Try changing the angle of the phone relative to the code.
If the code is on the screen of another phone (for example, when logging into WhatsApp Web), reduce the brightness of the second device's screen. A screen that is too bright creates glare that prevents the camera from reading the code.
In rare cases, you may need to reset the camera application settings. Go to Settings → Applications → Camera → Memory → Clear cache. This will not delete your photos, but will return the camera settings to factory settings, which often solves software glitches.
90% of scanning problems are solved by wiping the camera lens and changing the distance to the object by 5-10 centimeters.
Questions and answers (FAQ)
Is it possible to scan a QR code from a photo in the gallery?
Yes, it is possible. Open the photo with the code in the application Gallery or Google Photos. Click on the icon Google Lens (colored circle) or select the "Scan Code" option in the "More" menu. The system will analyze the image and provide a link.
Is it safe to scan codes from unknown sources?
Scanning itself is safe - it's just a picture. The danger is the link to which the code leads. Never enter personal data and passwords on sites opened via a QR code if you are not 100% sure of the source.
Why is there no scanning function on older Samsung models?
The automatic recognition function appeared in the shell Experience UI (predecessor of One UI) based on Android 8.0. If you have a device older than 2017, you will need a third-party application.
How to create your own QR code on Samsung?
There is no built-in function for creating codes in a standard camera. However, you can use the widget Bixby Vision or download any free generator application from the Play Store, of which there are hundreds. Codes can also be created online through a browser.
