Scanning QR codes is one of the simplest ways to access links, apps, and digital menus. But if your Galaxy S25 Ultra suddenly stops recognizing QR codes, it can be frustrating, especially when you rely on it for quick payments or check-ins.
This issue can happen for a few reasons, such as disabled camera features, poor lighting, or outdated software. Fortunately, it’s easy to fix.
Why Your Galaxy S25 Ultra QR Code Scanner Might Not Be Working
- The QR code scanning feature in the Camera app is turned off.
- Poor lighting or blurry lens affecting camera focus.
- Outdated system software or camera app.
- QR code image is damaged, too small, or too reflective.
- Temporary system glitches or cache errors in the Camera app.
Enable QR Code Scanning in Camera Settings.
The built-in QR scanner in the Camera app might have been disabled. Enabling it ensures your phone can detect codes instantly.
- Open the Camera app, and then tap Settings at the top-left corner.
- Scroll down and toggle on Scan QR codes.
Once enabled, point your camera at any QR code. A pop-up will appear when it’s detected.
Clean the Camera Lens and Improve Lighting.
Dirty lenses or dim environments can prevent your phone from recognizing QR codes properly. Keeping the camera clean and well-lit makes a big difference.
- Gently wipe the camera lens with a soft microfiber cloth.
- Move to a brighter area or adjust the angle to reduce glare or reflections.
Now, try scanning the QR code again. The camera should focus and detect it faster.
Restart the Camera App.
Sometimes the Camera app may freeze or glitch after long use. Restarting it refreshes the system and clears minor bugs.
- Swipe up from the bottom of the screen and hold to open Recent apps.
- Find Camera, swipe it up to close it, and then reopen it from your Home screen.
Try scanning a QR code again to see if the issue is resolved.
Check for Software Updates.
Outdated software can affect system performance and camera stability. Installing the latest update helps ensure QR code scanning works properly.
- Open Settings, and then tap Software update.
- Tap Download and install, and follow the prompts if an update is available.
After updating, restart your Galaxy S25 Ultra and test the QR scanner again.
Use Samsung Internet or Gallery QR Scanner.
If the Camera app still doesn’t recognize QR codes, try using alternative scanners built into Samsung’s ecosystem.
- Open the Samsung Internet browser, and then tap the menu icon at the bottom.
- Tap QR code scanner, and point your camera at the code.
You can also scan codes saved in photos. Open Gallery, select the image, tap the three-dot menu, and choose Scan QR code.
Clear Camera App Cache.
Corrupted cache data may prevent the camera from detecting QR codes. Clearing it can restore normal operation.
- Open Settings, and then tap Apps.
- Find and tap Camera, then tap Storage, and finally tap Clear cache.
This removes temporary files without affecting your photos or settings.
QR scanning issues on the Galaxy S25 Ultra are usually minor. In most cases, enabling the QR option or cleaning the lens quickly restores full functionality.
