ZTE has been more than willing to spill the beans about the Grand S ahead of CES, and it's not stopping with the mention that the phone exists. The Chinese phone maker has confirmed that its 5-inch smartphone measures just 6.9mm (0.27in) thick -- that's a sight slimmer than the Droid DNA and Nubia Z5. There's also mention of a 13-megapixel camera that explains a slightly visible rear hump. While we don't yet have confirmation of the rumored quad-core Snapdragon S4 Pro and 2GB of RAM, ZTE has left clues that the flagship could undercut typical pricing with a ¥2,799 ($449) off-contract cost in China. We may only know the full details in Las Vegas, but there's every indication that the Grand S hardware could justify a boast or two.
