Apparently, the tipster claims to hail from South Korea, and had just a few seconds in order to snap the photo – unfortunately, said tipster does not seem to be using a decent smartphone that would probably have gotten him (and the rest of the world) far better shots, as we end up with a typical blurry cam image instead.
What is shown on the right happens to be some sort of packaging, or perhaps an information sheet concerning a smart cover for the upcoming Samsung Galaxy Note 4. The oval window itself points to a fair amount of smart action functionality that ought to be part of the entire package, and who knows, since this is a Galaxy Note device, there might be some room for stylus interaction to boot. We would take this blurry image with a grain of salt, like all rumors, they will need to be substantiated by an official announcement.
