Iphone 5 camera & flash not working?

I still have the warranty for it, my phone works but the led flash can't open and only the facecam works I tried downloading a flash app but says led does not meet requirement or is not supported, I was wondering if apple would give me a new phone since it's a hardware issue:/ , I already tried resetting it etc.

Try going to your settings and see if its turned off if not that then its best for you to get another.
