With Samsung’s (005930) Galaxy S IV set to debut Thursday evening, the dam has finally broken. The slow trickle of leaked photos is now a river, and the highest quality images we’ve seen so far have been published by Chinese gadget blog IT168. While we likely already know nearly everything there is to know about the Galaxy S IV, these new photos show the handset’s sleek design in sharp detail, leaving nothing to the imagination. Samsung’s Galaxy S IV is expected to feature a 5-inch Super AMOLED HD display, an eight-core Exynos processor or a quad-core Snapdragon chipset depending on region, up to 64GB of storage, 2GB or RAM and Android 4.2 Jelly Bean. BGR will be on hand reporting live when Samsung unveils the Galaxy S IV Thursday night at 7:00 p.m. EDT, but in the meantime, several additional high-quality photos of the new smartphone follow below.
