My S3 Camera is zoomed in! HELPP PLEASEE

So I have a Samsung Galaxy s3 (NOT the Mini) and all the apps cameras are zoomed in. However, the normal pre-installed camera is completely fine. The Snapchat Camera is really zoomed in and I'm going on holiday soon and need it fixed. I have tried clearing the cache for Snapchat on settings and going on the actual app and clearing the memories and the other cache on it
