Hi Blaquem welcome to Android Forums, we can try and help you.
What happens when you open the camera app? - does it crash, nothing happens, black screen, error, etc. You could try factory resetting it, see if that fixes it. And if that doesn't work it's probably faulty, and will have to be returned for repair or replacement.
