The mobile industry is slowly but surely moving toward Quad HD (2K) displays on flagship smartphones. Samsung first dabbled in a QHD display with the Galaxy S5 LTE-A, and then brought it to a widely available phone like the Galaxy Note 4. Naturally, the Galaxy S6 is also expected to feature such a high-resolution display; we've already confirmed this in an exclusive report late last year, but if you still needed more confirmation, you only need to look toward the Galaxy S6's user agent profile (UAProf) on Samsung's website.
The UAProf is for the SM-G920A, which is the AT&T variant of the Galaxy S6. While the screen resolution is correctly mentioned, the UAProf does mention the wrong kind of processor. The SM-G920A is running on a 32-bit ARM11 processor according to the profile, which has little possibility of being right as the S6 is set to offer 64-bit support and an ARMv8 architecture; however, user agent profiles often list an outdated CPU before a particular device is launched, so this is something that can be ignored instead of being taken seriously.
As a refresher, the Galaxy S6 is set to feature a 64-bit Exynos 7420/Snapdragon 810 processor (though the Snapdragon variant might get delayed, or even get cancelled if Qualcomm is unable to fix its issues), 3GB of RAM, a 16/20-megapixel rear camera, a touch-based fingerprint sensor, and 32/64/128GB of internal storage. Samsung is also rewriting the software on the S6 from scratch, with rumors suggesting it will be as optimized as stock Android that you find on a Nexus device. The Galaxy S6 will also come with Sennheiser earphones out of the box, and consumers will be able to buy a range of accessories for the device.
