When the QR code scanner on your RealMe 16 stops working, simple tasks like logging into apps or opening links become frustrating.
Sometimes the scanner does not open at all, and other times it opens but fails to detect any code.
In most cases, this issue is caused by camera access problems, disabled features, or temporary system glitches.
Why Your RealMe 16 QR Code Scanner Is Not Working
- Camera permission for the scanner is disabled.
- The built-in scanner feature is turned off in system settings.
- The Camera app is outdated or malfunctioning.
- Low light or a dirty camera lens prevents scanning.
- Temporary software bugs after a system update.
1. Restart Your Phone
Restarting refreshes system services that the QR scanner relies on.
It also clears temporary glitches that may stop the camera from recognizing codes.
Open Settings, and then scroll down to System.
Tap Restart, and then wait for the phone to boot up fully.
2. Check Camera Permissions
The QR scanner cannot function if it does not have permission to use the camera.
This often happens after app updates or privacy changes.
Open Settings, and then tap Privacy.
Tap Permission manager, and then allow Camera access for the Camera app.
3. Enable the Built-In QR Code Scanner
On RealMe phones, the QR scanner can be turned off manually.
If it is disabled, scanning will fail even if the camera works normally.
Open Settings, and then tap Additional settings.
Tap QR code scanner, and then turn the feature on.
4. Clear the Camera App Cache
Corrupted temporary files can prevent the scanner from detecting codes.
Clearing the cache removes these files without deleting personal data.
Open Settings, and then tap Apps.
Tap Camera, and then select Storage and clear the cache.
5. Test in Good Lighting and Clean the Lens
Poor lighting makes QR codes harder to read.
A dirty or smudged camera lens can also block proper detection.
Move to a well-lit area, and then wipe the camera lens gently.
Open the Camera app, and then try scanning the QR code again.
6. Update the Camera App and System
Outdated software may contain bugs that affect scanning.
Updating ensures compatibility with newer QR formats.
Open Settings, and then tap Software update.
Download and install any available updates, and then restart your phone.
Once the QR code scanner on your RealMe 16 is working again, scanning should feel instant and reliable.
Most issues are simple to fix, and a few quick checks usually restore full functionality.
FAQs
Why does the QR scanner open but not detect any code?
This usually happens due to poor lighting, camera focus issues, or a dirty lens. Improving lighting and cleaning the lens often solves the problem.
Can I use a third-party QR scanner app on RealMe 16?
Yes. If the built-in scanner continues to fail, third-party apps from the Play Store can scan QR codes using the same camera hardware.
Does clearing the Camera app cache delete photos?
No. Clearing the cache only removes temporary files and does not delete photos or videos stored on your phone.
