I don't seem to have the Sports Shot mode either. When I check in the Galaxy store, it says it's installed, but it's not among the modes on my Camera. When I try to click on the app in the Galaxy store, the "Open" button is greyed out. The "Uninstall" button is working, so I uninstalled it then reinstalled, and no change.
Speaking of the modes, I'm not loving the way you have to scroll among them on the bottom of the viewfinder now, and definitely not loving that the video mode has to be called up separately, as opposed to just having the video's red shutter button there. Sometimes you want to get to video fast, and it can be easy to scroll right by it.
