My Samsung Galaxy S4 default Camera does NOT have setting option?

[AC Question]

I have just bought a selfie stick and of course, I want to change the function of volume key to capture. I search in the internet, and all of them talk about the "setting" option in camera app, which seem not available in my phone. I pressed menu key, nothing happen.
My device is Samsung Galaxy S4 GT-I9500 running Android 5.0.1.
So anyone can help me with this problem?
Thank you so much
