On my Google Pixel 8 Pro, it said the lens was uncovered and didn't work, even if I fully covered it. However, I tried it on a Google Pixel 4a, and it worked. It seems this app doesn't work on some phones, as they have an imbedded LED which bleeds infrared light into the camera. The light is invisible to the eye, but the camera's sensor can see it. If your camera sees a purplish light in its own reflection, it's incompatible. Even when working, it takes several minutes to complete a scan.

I have used your app successfully on cheap phones. I have a nice phone now and it just will not initialize the camera. It started off not allowing you to pic what camera to initialize. So I suspect the same is happening, trying to initialize both front and rear cameras and the screen noise, which the screen side camera is embedded in, is causing the whole things to fail. I did get through stage three and it said some phones won't work due to image noise. Why not allow the rear camera only.

This app does its job properly. For anyone not knowing, this app needs access to the camera because gamma rays can interact with the camera's sensor, showing a sort of "line". It needs completely dark environment (use black tape to cover lens) because to detect radiation, it measures the amount of light flashes in a determined amount of time. So, yes this app does indeed access the camera, for anyone concerned about that, but only if it is pitch black.
