My camera was still on in the app

I was scanning a QR Code with the app and I was done doing that but I did not close the app so my camera was still on but the QR Code scan screen was closed but not the app so I had to close the app because it might be a hacker do you know why it did this

Start by reproducing the QR-code scanning flow and leaving the app open after closing the scan screen. Trace the camera lifecycle in the relevant C# app entry points; done means the camera is no longer active when scanning ends, while the app remains open.
