QR code on Samsung: how to enable, scan and configure

QR codes have become an integral part of everyday life: from quick access to Wi-Fi to payment for purchases and authorization in services. Smartphone owners Samsung Galaxy often face the question of how to enable the QR code scanning function, especially if it is not activated by default. Unlike iPhone, where the scanner is built into a standard camera, Android (including devices Samsung) may require additional settings or installation of applications.

In this article we will analyze all the possible ways to work with QR codes on smartphones Samsung — from built-in tools to third-party solutions. You will learn how to enable the scanner in the camera, use Bixby Vision, set up quick access through the notification panel, and even create your own QR codes. We will pay special attention to the nuances for different versions One UI (from 3.1 to 6.0) and models - from budget Galaxy A to flagship Galaxy S23 Ultra.

If you previously tried to scan the code, but nothing worked, do not rush to blame the technology: often the problem lies in disabled permissions or outdated software. We will also look at typical errors (for example, when the camera does not recognize the code or displays the message “Function unavailable”) and how to eliminate them.

1. Built-in QR code scanner in the Samsung camera

Starting from One UI 2.5 (and later versions), most smartphones Samsung support scanning QR codes through the standard application Camera. However, this feature may be hidden or disabled. Here's how to activate it:

Open the application Camera and go to photo mode (Photo or Auto). Point the lens at the QR code - if the function is enabled, after 1-2 seconds a notification will appear asking you to follow the link. If nothing happens:

• 🔍 Check that the function is not disabled in the camera settings. Go to Camera settings → Smart functions → QR code scanner and activate the switch.
• 📱 Update the camera software via Galaxy Store or Google Play. Outdated versions may not support scanning.
• 🔄 Restart your smartphone - sometimes this helps to reset temporary glitches in the camera.

On models Galaxy S20 and newer, the scanner works automatically, but on older ones (for example, Galaxy A50 or Galaxy Note 9) may require manual activation. If there is no "QR code scanner" item in the camera settings, then your model does not support this function at the software level - you will have to use alternative methods.

2. Scan QR codes with Bixby Vision

Bixby Vision is a proprietary tool Samsungthat can not only recognize objects, but also read QR codes. This method works even on devices where the standard camera does not support scanning. To use it:

1. Open the application Camera.
2. Touch the icon Bixby Vision (eye icon in the bottom panel or side menu).
3. Point the camera at the QR code. The system will automatically recognize it and offer an action (open a link, save a contact, etc.).

If there are no icons: Bixby Vision No:

• 🔧 Make sure that Bixby is installed and updated (go to Galaxy Store and check updates).
• 📵 Enable Bixby in the settings: Settings → Additional features → Bixby.
• 🔄 Reinstall the application Bixby Vision via Galaxy Storeif it does not work correctly.

On models Galaxy S22 and newer Bixby Vision can be integrated into Google Lens —in this case, select the appropriate icon in the camera menu.

3. Quick access to the scanner via the notification panel

In One UI 4.0 and above Samsung added the ability to add a QR code scanner shortcut to the quick access panel. This is convenient if you use the function often. To configure:

1. Pull down the notification panel and tap the "⚙️" (edit) icon.
2. Find the button QR code scanner (or QR Scanner) in the list and drag it to the active area.
3. Save changes. Now you can scan codes directly from the notification panel without opening the camera.

If the button QR code scanner is not in the list:

• 🔄 Update your smartphone firmware to the latest version One UI.
• 📱 Install the application Samsung Members and check for available updates for system components.
• 🔍 On some models (for example, Galaxy A12) this function may not be available due to hardware limitations.

4. Third-party applications for working with QR codes

If the built-in tools Samsung are not suitable (for example, on older models or after a factory reset), you can use third-party applications. Here are the top 3 proven options:

Application	Features	Link
QR & Barcode Scanner (Gamma Play)	Fast scanning, code history, work without the Internet	Google Play
Kaspersky QR Scanner	Checking security links, blocking phishing sites	Google Play
Barcode Scanner (ZXing Team)	Open source, supports all barcode formats	Google Play

When choosing an application, pay attention to:

• 🛡️ Security: avoid little-known scanners with suspicious permissions (for example, access to SMS or contacts).
• 📱 Compatibility: some applications may not work on older ones versions of Android (below 8.0).
• 🔄 Updates: check when the last update was released (if long ago, there is a risk of vulnerabilities).

After installing the scanner, open it and point the camera at the QR code. Most applications will automatically recognize the code and suggest an action (open the link, save the text, add an event to the calendar, etc.).

How to check the security of a QR code before opening?

Before clicking on a link from a QR code, pay attention to:

1. Site domain - if it contains typos (for example, go0gle.com instead of google.com), this could be phishing.

2. Protocol —secure sites use https://rather than http://.

3. Context —do not scan codes from suspicious sources (for example, stickers on street lamps).

If in doubt, use a scanner with a security check (for example, Kaspersky QR Scanner).

5. Creating your own QR codes on Samsung

In addition to scanning, Samsung you can generate your own QR codes - for example, to transfer contacts, connect to Wi-Fi or quickly access a website:

Method 1: via Contact

1. Open the application Contact and select the desired contact.
2. Click "Share" (icon with three dots or an arrow).
3. Select QR code —the system will generate a code with the contact data.
4. Save the image or share it via instant messengers.

Method 2: via Wi-Fi Settings

To create a QR code to connect to your network Wi-Fi:

1. Go to Settings → Connections → Wi-Fi.
2. Select your network and click "Share" (or "QR code").
3. If necessary, enter the lock screen PIN code.
4. Scan the generated code with another device for quick connection.

To generate codes with arbitrary text or links, use online services (for example, QR Code Generator) or applications like QR Code Generator from Google Play.

6. Typical problems and their solutions

Even after proper configuration, the QR code scanner on Samsung may not work correctly. Let's look at the most common errors and how to fix them:

⚠️ Attention: If after the update One UI the scanner stops working, reset the camera settings to factory settings: Settings → Applications → Camera → Storage → Reset settings. This will not delete your photos, but will return the default settings.

Problem	Possible reason	Solution
The camera does not recognize the QR code	Weak lighting, dirty lens, damaged code	Wipe the camera, improve the lighting, try a different code
The error "Function is unavailable" appears	Disabled permissions or outdated software	Update One UI and check the permissions for the camera
The scanner opens the wrong link	QR code contains a redirect or malicious link	Use a scanner with a security check (for example, Kaspersky)
There is no scanner button in the notification bar	Unsupported model or version One UI	Install a third-party application or update the firmware

If none of the methods help, reset the camera settings or (as a last resort) reset the smartphone to factory settings. Before doing this, do not forget to save important data!

7. Safety when working with QR codes

QR codes are convenient, but can be dangerous if they contain malicious ones. links or commands. Follow these rules to avoid problems:

• 🔒 Do not scan codes from suspicious sources (for example, stickers on the walls, unknown letters or messages).
• 🛡️ Use secure scanners (for example, Kaspersky QR Scanner or Google Lens), which check links for phishing.
• 🔍 Check the URL before opening —if the address looks suspicious (for example, paypa1.com instead of paypal.com), do not click on it.
• 📵 Disable automatic actions in the scanner settings, if there is such an option.

Be especially careful with QR codes that:

• 💳 Ask enter bank card details or logins/passwords.
• 📱 Offer to download the application (especially outside Google Play).
• 🔄 Redirect to strange sites with errors in the address.

⚠️ Attention: Fraudsters often use QR codes to steal data. For example, the code can open a phishing site that imitates a login page to the bank. Always check the website address before entering personal information!
