I'm sorry to hear that you're experiencing issues with the QR code scanner on your Samsung Galaxy A14 5G. Here are a few troubleshooting steps you can try to resolve the problem:
Clean the Camera Lens: Ensure that the camera lens is clean and free from any smudges or dirt. A dirty lens might affect the QR code scanning process.
Update the Camera App: Make sure that your camera app is up to date. Check the Google Play Store for any available updates to the Camera app, and if there are any, install them.
Restart Your Phone: Sometimes, a simple restart can resolve software glitches. Restart your Samsung Galaxy A14 5G and try scanning the QR code again.
Test in Safe Mode: Boot your phone into Safe Mode to check if a third-party app is causing the issue. In Safe Mode, only pre-installed system apps are active. If the QR code scanner works in Safe Mode, it's likely that a third-party app is causing the problem.
To enter Safe Mode, press and hold the power button until the Power Off option appears.
Press and hold the Power Off option until the Safe Mode prompt appears.
Tap "OK" to enter Safe Mode.
In Safe Mode, try using the QR code scanner and see if it works. If it does, you may need to uninstall recently installed apps until you find the one causing the problem.
Clear Cache and Data for Camera App: Go to Settings > Apps > Camera. Clear both the cache and data for the Camera app. Keep in mind that this will reset any custom settings for the camera app.
Factory Reset: If none of the above steps work, you may consider performing a factory reset on your device. Before doing this, make sure to back up your important data, as a factory reset will erase all data on your phone.
Go to Settings > General Management > Reset > Factory data reset.
After the reset, set up your device again and check if the QR code scanner is working.
If the issue persists after trying these steps, you may want to contact Samsung support for further assistance or visit a Samsung service center.
