Samsung Galaxy S3 Camera problem... fake or not?

Hi, I just bought Samsung S3 like an hour ago...I didn't spend too much time on it yet... but I checked the camera and I couldn't use it as i wanted.. I mean I just didn't like the quality and I thought maybe this samsung is fake and that's why it doesn't include all the features/options... I checked few videos on youtube all their settings/options are different on the menu..

I can't seem to use the feature of taking 20 pics in short amount of time... and the pictures i take aren't reall good quality.. so here is all the options i've got on the camera menu.... Maybe there's some stuff I have to set up on settings because that's how I worked some of other features... please take a look at these photos and let me know what you think and if you have a solution...
