So a few weeks ago my camera stopped working. The UI comes up but the screen is black. I was running cssu testing and power kernel. I went threw the whole f cam drivers / restore the stock kernel which worked the first time this happened a few moths ago.

This time it didnt, so I reflashed the device and when I open the camera app I get operation failed. I have also reformatted the device as well.

I think it is the hardware itself. The last thing I did was use the flashlight app, when i used it it made a loud click almost if there was a shutter. I'm wondering if there is some type of shutter or anything that could be serviced in order to get it working again.
