Why does my Camera not work even after factory reset?

[AC Question]

My phone switches from saying camera unavailable to camera unfortunately stopped working. I tried clearing cache and data for camera, using a third party camera app, and doing a factory reset. None of them worked. My flashlight also will not work saying camera may be open even though it is not.

Perhaps the camera has failed, or some internal connection?
