My iPhone camera won't work?

So a few weeks ago I accidentally dropped my iPhone 5s and I checked it, everything seemed fine but then I tried to use the flashlight and it just wouldn't work like I'd hit it and nothing happened at all. I checked the camera and the back camera wouldn't work either like it's just black, but the front camera does work. It's kind of a pain having to take all of my photos with a front camera or having to use someone else's and was wondering how I could fix it without having to pay to get it fixed?

Do you know how to fix or replace parts inside your phone?
Do you have AppleCare+?

If the answer is NO, to both questions, you either take your phone to Apple to be repaired or replaced, or you find a local cell phone repair shop and have them fix it for you.
