IPhone 5 problem? How to turn off sound with snapchat?

I have an iPhone 5 and my brother was messing with my phone earlier and was throwing it up and down and it slide out of his hands and slammed on the ground. It's in an otter box no scratches or physical injury but when I started using my phone I noticed all the sounds things I had set up hanged. Like my notification sounds for messages came on. Now on snapchat when I take a picture it makes the clicking noise! How do I turn it off? I can't find anything in settings

I don't have the knowledge, but try asking at&t or whichever company you get your service from.
