Yes. Just download the Nexus' camera app onto your Samsung device and install it. You'll end up with 2 camera and gallery apps. They all have different icons, though, so you can visually see which one you want to open.
See the following link for a download link and instructions.
Use the Google camera app to create photospheres. Note that to view the photospheres, you must also use the Google Gallery app (which is also installed).

In ADW, I created a folder called Camera and changed the icon names for the two camera apps to help distinguish between the two. I don't know if TouchWiz can created folders or change the icon labels, though; I installed ADW Ex as soon as I got the phone.
