With the Samsung Galaxy S 4 launch only one day away, Bloomberg has confirmed some of the details we've heard elsewhere — and refuted others. According to sources, the Galaxy S 4 will come with a 5-inch screen and a quad-core Qualcomm processor in the US; elsewhere, it will use Samsung's own 8-core Octa chip. It's also rumored to use a 13-megapixel rear camera, compared to the 8-megapixel Galaxy S III. Previous leaks have pointed to a 1080p screen, and a UK carrier has confirmed it will come with LTE.

Though none of this is too surprising, Bloomberg also contradicts an earlier New York Times report that the S 4 would implement automatic scrolling based on the user's eye movement. While later versions might track eye motion with that level of sophistication, sources have said that simpler uses will be in place at launch: the phone will be able to do things like pause video when the user looks away from it, for example. The Galaxy S III currently incorporates a feature called Smart Stay, which keeps the screen bright as long as the user is focused on it.
