Samsung Galaxy phones have built-in QR code scanning in multiple places — but most people only know about one of them. This guide shows you three ways to scan QR codes on Samsung, including how to decode codes from screenshots and images without using the camera.

Method 1: Samsung Camera App

The quickest way to scan a physical QR code that's in front of you.

Open the Camera app on your Samsung Galaxy phone.
Point it at the QR code — Samsung's camera automatically detects QR codes when they're clearly visible in the viewfinder.
Tap the pop-up link that appears on screen to open it, or tap the QR icon to see the full decoded content before navigating.

If QR scanning isn't working in your Camera app, go to Camera Settings (tap the gear icon in the camera) and make sure "Scan QR codes" is turned on. This setting is enabled by default on most Samsung phones running One UI 2.0 or later.

Quick Settings Shortcut

Samsung also offers a QR scanner tile in Quick Settings. Swipe down from the top of your screen to open the notification panel, swipe down again to see all Quick Settings tiles, and look for "Scan QR code." If you don't see it, tap the pencil/edit icon to add it. Tapping this tile opens a dedicated QR scanner that's slightly faster than launching the full Camera app.

Method 2: Samsung Gallery (for Screenshots & Saved Images)

If you have a QR code saved as an image or screenshot on your Samsung phone:

Open the image in Samsung Gallery.
Tap the Bixby Vision icon (the eye icon at the bottom of the screen) or look for the QR code detection option in the toolbar.
Samsung reads the QR code and displays the content in an overlay.

Note that Bixby Vision's QR detection can be inconsistent, especially with low-contrast codes, small codes, or QR codes that aren't centered in the image. If it doesn't detect the code, Method 3 is more reliable.

Method 3: QR Code Gadget Decoder (Works on All Samsung Models)

For QR codes in PDFs, emails, websites, or any image — especially when Samsung's built-in options don't detect the code:

Screenshot the QR code (press Power + Volume Down simultaneously) or save the image to your gallery.
Open Samsung Internet (or Chrome) and go to QRCodeGadget.com/qr-decoder.
Upload the image — tap "Choose Image" and select your screenshot from the gallery.
The decoded content appears instantly. Copy the text or tap to open the link.

This method uses a multi-pass detection algorithm that analyzes images at multiple scales and contrast levels, so it catches QR codes that Samsung's built-in scanner sometimes misses — especially small codes, low-contrast codes, codes on colored backgrounds, or partially obscured codes.

Which Method Should You Use?

Physical QR code in front of you → Use the Camera app (Method 1) or the Quick Settings scanner
QR code in your photo gallery → Try Samsung Gallery first (Method 2), or use QR Code Gadget (Method 3) if Bixby Vision doesn't detect it
QR code in a PDF, email, or website → Screenshot it and use QR Code Gadget (Method 3)
QR code not being detected → Use QR Code Gadget's advanced decoder (Method 3) — it handles tricky codes more reliably

Works on All Samsung Galaxy Models

These methods work on all Samsung Galaxy phones including the latest Galaxy S25 and S24 series, the Galaxy A series (A55, A35, A15, etc.), Galaxy Z Fold and Z Flip models, and older Galaxy phones. The Camera app scanning requires One UI 2.0 or later, but the browser-based QR Code Gadget tool works on any Samsung phone with a web browser — even models running older versions of Android.

Troubleshooting Samsung QR Scanning

If QR codes aren't scanning through the Camera app, verify the setting is enabled in Camera Settings. Make sure you're in Photo mode (not Video or Portrait). Ensure the QR code is well-lit, clearly visible, and your camera lens is clean. If the code is very small, try moving closer. If you're scanning through glass or a screen protector that's very thick, the camera may have trouble focusing — try removing the case temporarily or adjusting the angle.

For the Gallery/Bixby Vision method, it helps to have the QR code large and centered in the image. Cropping the image to show just the QR code area often improves detection. If neither Samsung method works, the browser-based decoder is your best fallback.

Frequently Asked Questions

Why doesn't my Samsung camera detect QR codes?

Go to Camera Settings and enable "Scan QR codes." If it's already on, make sure the QR code is clearly visible, well-lit, and that you're in Photo mode. For tricky codes, use the QR Code Decoder instead.

Can I scan a QR code from a PDF on Samsung?

Yes. Take a screenshot of the QR code in the PDF (Power + Volume Down), then upload it to the QR Code Decoder at QRCodeGadget.com.

Do I need to download a QR scanner app?

No. Samsung has built-in scanning in the Camera app and Gallery, and QR Code Gadget works in your browser. There's no need to install a third-party QR scanner app from the Play Store.

Does the scanner work on Samsung tablets?

Yes. Both Samsung's built-in QR scanning and QR Code Gadget's browser-based tools work on Samsung Galaxy tablets (Tab S series, Tab A series, etc.) the same way they work on phones.
