Default behavior on a Galaxy S4 (likely the same on a Tab 3) is to use the volume as zoom, but you can change that in settings for the camera app. Open the camera app, tap the gear icon, then tap gear again, and finally select the gear tab (this is the order in my Lollipop S4; may differ in detail on Kit-Kat or Marshmallow). One entry is "Volume Key" and you have the option to select "zoom" or "take picture".
