With just over one day left until Samsung (005930) unveils the Galaxy S IV, new details have begun to trickle out. Earlier reports claimed the company’s flagship smartphone would include eye-tracking technology, however this may not be the case. According to Bloomberg, the Galaxy S IV will not include the feature at launch, although it may appear in “future versions of the phone.” Samsung will instead use a simpler head-tracking technology that will have the ability to pause videos when a user turns away from the screen.

Bloomberg also claims to have confirmed that the Galaxy S IV will come in two variants, one with a Qualcomm (QCOM) Snapdragon 600 processor and the other with Samsung’s own Exynos 5 Octa CPU. The U.S. version of the device will feature the quad-core Snapdragon processor because of its integrated LTE radio, while international models will be equipped with Samsung’s eight-core CPU.

The Galaxy S IV will also include a 4.99-inch full HD 1080p display, 2GB of RAM, wireless charging capabilities, a micro SD slot and a 13-megapixel rear camera. Samsung will announce the smartphone at a press conference on Thursday at Radio City Music Hall in New York City, where BGR will be on hand to bring you the news as it breaks.
