It looks like at least one major U.S. carrier is already testing its variant of the Galaxy S5. @evleaks has revealed on Twitter that AT&T is testing an SM-G900A with a high-resolution screen – we've already seen two other possible variants of the Galaxy S5, the SM-G900S and SM-G900F, and instead of being standard and super-premium versions of the flagship as has been speculated, these could simply be different models for various carriers.
Keep in mind that just because the handset is already being tested by a carrier doesn't mean it's too close to launch. Some rumors suggest the Galaxy S5 might be launching earlier than the Galaxy S4 did in 2013, while another hints at a standard April launch, so it remains to be seen when we're able to get a look at Samsung's anticipated fifth-generation Galaxy S flagship.
The Galaxy S5 is expected to sport a QHD (2,560×1,440) 2K display, a Snapdragon 800/805 processor/64-bit Exynos processor, 3GB of RAM, 16-megapixel camera, and Android 4.4 KitKat. It is also expected to be the first Samsung flagship to have a metal construction, at least on one of its variants.
AT&T is testing a version of that high-res Samsung handset (SM-G900A), giving some support to the theory that it's an int'l flagship (GS5?)
