Owners of Samsung smartphones are often faced with the need to read a QR code that is located directly on the screen of their device. This could be a link to a friend's Wi-Fi network, a gift certificate in instant messenger, or a ticket to an event. Owners of Samsung smartphones are often faced with the need to read a QR code that is located directly on the screen of their device. This could be a link to a friend's Wi-Fi network, a gift certificate in instant messenger, or a ticket to an event. Previously, such tasks required installing separate applications from the Play Market, which created an extra load on the system. However, modern versions of the One UI shell and Google services allow you to perform this procedure using standard means.
In this article we will analyze in detail all the available methods for scanning QR codes without downloading third-party software. We'll look at the capabilities of the built-in camera, the Google Lens feature, and even the voice assistant. Using native tools guarantees the security of your data, since you do not provide access to the camera and files to dubious developers. You will learn how to quickly follow a link or save a contact by simply taking a screenshot or pointing the camera at the display.
Using the built-in Samsung camera for scanning
The most obvious and fastest way is to use the standard application Camera, which comes pre-installed on every Galaxy device. In the latest versions of the One UI firmware, the camera functionality has been significantly expanded. Now it automatically recognizes QR codes without having to press additional buttons or switch modes. You just need to point the lens at the code.
To scan the code from another screen (for example, from a tablet or second phone), simply open the application Camera and point it at the image source. If the code is on the screen of your own smartphone, the situation becomes more complicated, since you cannot take a photo of yourself. However, if you have the ability to mirror the screen to a monitor or use the Smart View function to broadcast to a TV, the camera can easily read the code from a large display.
Make sure the scanning function is active in the settings. Sometimes users accidentally disable it while trying to speed up the shutter. To check, go to the camera settings through the gear icon and find the item Scan QR codes. It must be turned on. When you hover over the code, a yellow frame and a pop-up notification with a link will appear on the screen.
⚠️ Attention: The automatic recognition function may not work if the lighting is too dim or if the source device screen has anti-scanning protection (for example, flicker or a specific filter). In such cases, try increasing the brightness of the screen.
If the camera does not focus on a small QR code, try moving the phone a little away or touching the screen in the code area to force the focus.
Scanning QR codes through a screenshot and Google Lens
This is the most effective method for the situation when the code is located exactly on the screen your Samsung phone. You don't need to look for a second device. The entire procedure takes a few seconds and does not require an Internet connection for the recognition process itself, although you will need a connection to follow the link. The algorithm of actions is extremely simple and intuitive.
First, take a screenshot of the screen on which the QR code is displayed. Use the key combination Volume down + Power or swipe the edge of your palm across the screen if you have the function enabled Palm swipe to capture. After taking a photo, a thumbnail will appear in the corner of the screen. Click on it to open the editor, or find the image in the application Gallery.
At the bottom of the screen or in the “three dots” menu you will see an icon Google Lens (a square with a dot inside or an eye icon). Clicking on this icon will start the image analysis process. The system will automatically find the QR code, highlight it with a frame and suggest actions: open a link, save a contact or show text. This works even if the code is partially covered by interface elements.
- 📸 Take a high-quality screenshot, making sure that the code fits completely within the visibility area.
- 🔍 Click on the Google Lens icon in the gallery or in the preview panel screenshot.
- 🚀 Select the link or action that appears in the pop-up window.
- 💾 Save the image in a separate folder if you plan to use the code again.

The Bixby Vision function and its role in recognition
Samsung has integrated its own computer vision module called Bixby Vision directly to the camera application. While Google Lens is a more universal solution, Bixby Vision does a great job in Samsung's ecosystem. This tool can not only read codes, but also translate text, search for products on the Internet and determine the calorie content of food.
To access this function, open the camera and click on the icon Bixby Vision (usually a square with dots or an eye icon in the corner of the viewfinder). If there is no icon, the module may be disabled in the settings. After activation, point the camera at the screen with the code. The system will analyze the image and display the result at the bottom of the screen. Unlike the standard mode, here you can see additional processing options.
The Bixby Vision interface can sometimes be overloaded with advertising or shopping offers if the code leads to a product. However, for simple links and text data it works reliably. It is important to note that for Bixby Vision to fully function, you must be logged into your Samsung account and have an active Internet connection, as some of the processing takes place on servers.
⚠️ Attention: The interface and availability of Bixby Vision functions may vary depending on the region where the device is sold and the One UI firmware version. In some countries, this service is limited or replaced by partner solutions.
Why may Bixby Vision not work?
The module may not function if Google Play services are disabled or if the device was purchased in a region where Samsung services are limited. Also check the permissions for the Camera app.
Alternative methods: Quick Settings panel and Google Assistant
Besides the camera and gallery, there are less obvious ways to activate the scanner. In some versions of Android and One UI shells, a separate widget has been added to the quick settings panel (curtain). To check its presence, pull down the notification shade twice and look for the corresponding icon. If it is not there, click on the pencil (edit) and add a button from the list of available ones. QR code scanner. To check its presence, pull down the notification shade twice and look for the corresponding icon. If it is not there, click on the pencil (edit) and add a button from the list of available ones.
Another powerful tool is the voice assistant Google Assistant. You can activate it with the command “Hey Google” or by long pressing the power button (if configured). Say the command “Scan QR code” or “Open scanner”. The Assistant will launch the Google Lens interface in a special mode, ready to point at an object. This is convenient if your hands are full.
The browser is also worth mentioning Samsung Internet. A scanner icon sometimes appears in the address bar of this browser when you click on the URL input field. This allows you to quickly read the code and immediately open the link in the browser, bypassing the system gallery. Functionality depends on the browser version and installed plugins.
| Method | Internet required | Working speed | Convenience |
|---|---|---|---|
| Standard camera | No (for scanning) | Instant | High |
| Google Lens (screenshot) | Desirable | 2-3 seconds | Very high |
| Bixby Vision | Yes | Medium | Average |
| Quick settings panel | No | Instant | Depends on the presence of the widget |
Setting permissions and troubleshooting problems
If none of the methods described above work, the problem may lie in your privacy settings. Apps need access to the camera and, in the case of Google Lens, file storage to analyze screenshots. Without these permissions scanning will be blocked by the Android security system.
Go to Settings → Applications and find “Camera” and “Google” in the list. Make sure they have camera access enabled under Permissions. For the Google app or Google Photos, also check access to Photos & Videos or Files. If access is denied, the system will not allow you to analyze the image from the screenshot.
Sometimes clearing the application cache helps. Go to Settings → Applications → Camera → Storage and click Clear cache. Don't click Clear Data if you don't want to reset your camera to factory settings. After these steps, reboot your device and try again.
⚠️ Attention: If you use the Energy Saver mode, some background services required for Google Lens to work are disabled. may be limited. Disable energy saving for the scanner to work correctly.
90% of scanning problems can be solved by checking permissions to access the camera and gallery in application settings.
Security issues when scanning codes
Although we are talking about standard tools, it is important to remember the nature of the QR codes themselves. They may contain malicious links leading to phishing sites. Samsung and Google's built-in scanners usually warn the user if a link is flagged as dangerous in the security databases. However, you should not blindly trust the automation.
Before clicking on the link, carefully look at the address that is displayed in the pop-up window. If the domain name looks suspicious or different from the expected service, do not click the go button. For example, if you scan a code to pay for parking, the link should lead to the official website of the parking service, and not to a set of random characters.
Using built-in tools is safer than third-party applications, since they work in the “sandbox” of the system and have fewer rights to access personal data. Third-party scanners often require access to contacts, call history, and location, which is overkill for their function.
Can you scan a QR code if your phone screen is broken?
Yes, you can. If touchscreen doesn't work but you can see the image, you can use Google Assistant voice commands to launch the camera or navigate menus. Connecting a USB mouse via an OTG adapter to control the interface and take a screenshot will also help.
Why doesn’t the camera see the QR code on a bright screen?
This may occur due to the moire effect (overlay of pixel grids) or too high brightness, which “exposes” the contrast of the code. Try reducing the brightness of the source screen or changing the angle of the camera relative to the display.
Does scanning without the Internet work on Samsung?
The process of recognizing the graphic pattern of a QR code works offline. However, if the code contains a link to a website, you will need the Internet to follow it. If the code contains just text or a phone number, the Internet is not needed.
How to disable automatic opening of links after scanning?
In the Camera application settings, find the section related to scanning QR codes. There may be an option to “Open links automatically.” Disable it if you want to first view the address manually before proceeding.
