The Korean tech giant Samsung is leaving no stone unturned to bolster Galaxy S3 sales. A series of photographs showcasing a black Galaxy S3 have surfaced on the official Samsung Olympics Facebook page. The pictures on the Facebook page were uploaded to demonstrate how the Galaxy S3's features can enhance the Olympic experience.

ITProPortal spotted the images, which show the purported black S3 next to a white version, with the Olympic stadium as the backdrop. The photograph sports a caption about the S Beam, an NFC tool for beaming photographs, and other Galaxy S3 specs. Another picture in Samsung's Olympic album shows a dark-hued S3 being used to take photos of a tube train.

The color of the device in these pictures has created some furor, fueling speculations that it appears to be a black variant of the Galaxy S3. Currently, Samsung offers three color variants of the S3 on the market: Marble White, Pebble Blue, and Garnet Red; the Garnet Red S3 is an AT&T exclusive.

Are these photos spotted on Facebook a subtle hint from Samsung that it is going to release a black version of the smartphone? The images could depict a prototype that accidentally made its way into the hands of the Samsung photographer. Skeptics aver that the images could simply be the Pebble Blue model itself, which looks darker in the photos because of light variations.

However, if the device is indeed a black variant of the top-selling smartphone, Samsung is cleverly using the Olympic platform to publicize its color variant marketing maneuver. Releasing phones in a spectrum of colors is a well-known promotion ploy, which aids sales momentum even after the initial craze and enthusiasm of the launch have died down. Samsung could be taking this route, especially with the expected September debut of the iPhone 5 looming large.

Moreover, the company may want to keep tradition alive - its two previous models in the Galaxy S series came in black.

The spiffy Galaxy S3 breezed past the 10 million sales mark with ease less than two months after its release. With Samsung as the official sponsor for the London Olympics and deploying a colossal marketing budget, the flagship phones' sales can only expect an upward trend - at least till the fabled iPhone 5 launches. Samsung has been touted as the iPhone killer, but tech aficionados assert that the iPhone 5 may steal the Galaxy's thunder. It is no surprise, then, that the iPhone's nemesis is pulling out all the stops.
