The rumor mill has been on an overdrive regarding ZTE's uber thin Grand S smartphone. Now, per reports, the Chinese company has gone ahead and previewed its Grand S smartphone in multiple colors, ahead of the CES 2013 launch.

On Tuesday, Jan. 1, ZTE held a short preview of the device at its design offices in Shanghai, China. During the preview, ZTE staff confirmed that the 5-inch Grand S (1080p display) would be the company's international phone, whereas the Nubia Z5 (launched post Christmas) would be available only in the Chinese market.

The upcoming Grand S is one of the thinnest smartphones to hit the market, and it is conjectured that the device will be affordable (without compromising on the features).

ZTE did not give away too many details regarding the Grand S' hardware; however, the company let on that the smartphone will be 6.9mm thin, have a 0.55mm OGS display, and a narrow 3.14mm bezel.

 "ZTE haven't gone on the record and given us official specs for the Grand S and won't likely to until it's launch at CES, but sources close to the company have gone on the record as stating the phone will come with a quad-core CPU, 2GB RAM, 13-mega-pixel rear camera and Android Jelly Bean," reported GizChina.

Reports also suggest that CPU is a Qualcomm S4 unit, similar to the chip found in the Nubia Z5 and OPPO's Find 5. Additionally, the 13-megapixel camera sensor could well be a Sony ExymorPro unit, which can capture videos at 120 frames per second.

The Grand S is confirmed to be launched in several color options, which include black, gray, white, pink, red, blue, and lime green. The Grand S is rumored to sport a price tag of 2700 Yuan ($440).

With ZTE's date with CES 2013 barely a few days away, it remains to be seen if the company has any surprises left up its sleeve, or if it has pulled out all the rabbits already!
