Samsung's next-generation Galaxy S6 smartphone is set to release soon, and while the company has been its usual tight-lipped self, new details are beginning to emerge about what should be one of the most exciting tech devices of the year.

For starters, it looks like the Samsung Galaxy S6 will come in four colors. According to Samsung-centric website SamMobile, the Galaxy S6 and its edge variant should come in the following color options: dark blue, blue-green, gold and white. Although SamMobile attributes the information to one of its unnamed insiders, the blog has had a fairly strong track record when it comes to leaking Samsung information.

What's the Edge variant, you ask? The Samsung Galaxy S6 will reportedly release in two forms: a "normal" one and an "Edge" model. Samsung debuted its Edge line with the Galaxy Note Edge, and the premise is expected to be the same. The Galaxy S6 Edge variant will feature a curved display and droops over the sides, giving the phone screen real estate even when it is face down. SamMobile notes that the Galaxy S6 Edge's side panels will feature a more advanced interface than the Galaxy Note Edge's.

As far as specs go, there is nothing concrete, but rumor has it the Galaxy S6 will ship with a 5-inch or 5.2-inch QHD display, a Mali-T760MP6 GPU, 3GB or 4GB of RAM, and either a 16-megapixel or 20-megapixel rear-facing camera. One of the biggest changes this year, however, is it looks like all Galaxy S6s will ship with Samsung's own eight-core Exynos 7420 processor. Previously, Samsung usually shipped Galaxy S handsets to the United States and other regions with a Qualcomm chip, but it looks like Samsung won't be working with Qualcomm this time around.

Of course, none of this is set in stone. In fact, Samsung is said to be putting the Galaxy S6 through some of its most rigorous testing, thanks to the subpar performance of the Galaxy S5 last year. The South Korean company is reportedly testing multiple designs, so any information before the actual unveiling could be rendered moot by another day in the lab. What you can expect, however, is a smartphone that's most likely slimmer and more chic than previous Galaxy S phones -- the obvious trend.

Samsung is also said to be streamlining its TouchWiz interface to make it less clunky and memory intensive. TouchWiz is Samsung's in-house interface layered on top of Android. The interface has received criticism over the past years for being too gimmicky and slowing down system performance in the process.
