CAMERA BROKEN

Camera just randomly didnt work today when I went into app. I have an iPhone 5s and its always worked fine. This happened once before and I usually just delete and redownload the app if somethings broken like this, but this time that didnt help, the camera still doesnt work I cant even take a picture of the black screen. And not to be one of "those" people, but I have a few snapstreaks I need to keep going. Please fix!
