Feature description

Fossify Camera should include a built-in QR code scanner mode. This would allow users to quickly scan QR codes without needing a separate app. The feature could be added as a toggle or mode within the camera interface.

Why do you want this feature?

Currently, users must rely on third-party apps to scan QR codes, which adds unnecessary steps. Having an integrated QR scanner would improve convenience and make Fossify Camera more versatile. Many modern camera apps include this functionality, and it would be a useful addition for everyday use.

Additional information

The scanner should automatically detect QR codes when the camera is pointed at them.

A quick action (e.g., opening a link, saving contact details) should be displayed upon detection.

Could be implemented as a separate mode or automatically work when a QR code is in the frame.
