Samsung has made some major changes to its TouchWiz UI through the Galaxy S3. In fact, they made so many, that it took a 26-minute video from us to touch on about half of them. The video is below and includes a tour of the camera, S Voice, UI customizations, and more. If you were looking for a more detailed video of this latest custom skin from Sammy, you may not find one elsewhere. This video was also posted in our full Galaxy S3 review, in case you missed it.
