Samsung's Galaxy S2, with its impressive specifications and ultra-thin design, has left customers salivating. But while U.S. customers are still gearing up for the phone's arrival, a new report suggests that an LTE model is also under wraps.

A Galaxy S2 4G LTE device has surfaced in Korea. The device, which is called Celox, though similar in design to Galaxy S2, features a larger 4.5-inch Super AMOLED Plus display. It is surmised that the 4G LTE device will be powered by a 1.5GHz dual-core Qualcomm APQ8060 processor, and it will have 16GB internal memory, with an 8MP camera.

Celox is also expected to be fitted with a 1750mAh battery and will come pre-installed with Android Gingerbread.

Celox beats its cousin Samsung Galaxy S2 in terms of hardware upgrades. The currently available Galaxy S2 features a 4.3-inch Super AMOLED display with 800x480 screen resolution, a 1.2GHz dual-core Orion processor and Li-lon 1650mAh battery.

However, the Celox model will be slightly thicker than the Galaxy S2 model, as it is expected to be 0.36-inch thick. Galaxy S2 is super thin, at a mere 0.33 inches. Also, Celox weighs more than the Galaxy S 2 at 4.5 ounces, while the Galaxy S2 is super-light at 4 ounces.

The Samsung Celox features seem identical to rumored features of the Samsung Hercules, which is expected to be launched in August. If reports regarding Samsung Celox 4G LTE are true, then Motorola's Droid Bionic, which features similar specifications, has a lot to contend with.
