Repair iPhone 5s – rear camera does not work

Once I dropped a new iPhone 5s from a knee-height onto a tile, the phone was in a protective bumper, as soon as I lifted it, I noticed that the flashlight button was not active. I rebooted it, the button became active and the flashlight worked, at that moment I even shot a video, but the next day when the camera was turned on, a black screen was displayed when the camera was turned on.
