Why is my Snapchat camera not working?

[Android Central Question]

My camera doesn't really work when I try taking pictures with/out the flash on. It doesn't show a black screen but when I press to take a picture the picture comes out blurry even when I focus it. And no I'm not shaking the camera either but when I use the flash to take a picture the screen goes half way white and half of the background. I don't know if I'm making any sense but I hope I can get an answer to my problem.
