As the highly anticipated release date for the Samsung Galaxy S3 draws near, it seems that more and more details about the device are spilling out. The Korea-based company's flagship smartphone is set for a May 3rd unveiling, but the device may have just been leaked in Vietnam, according to Engadget.

A video was published on Vietnamese news site Tinhte displaying the GT-I9300, which is said to be the Galaxy S3. The clip revealed specific features about the upcoming phone, such as a 4.6-inch display sporting a resolution of 720 x 1184. Samsung's Galaxy S3 is sure to be a smooth-running device, with 1.4 GHz processor working to ensure the latest Ice Cream Sandwich operating system flows nicely.

According to the leaked video, an 8-megapixel camera is also in the works, although this contradicts an earlier leaked report. On April 19th a Gizmodo Brazil source claimed the next-generation smartphone will feature a 12-megapixel camera. In the footage, the user shows that the camera resolution can be changed manually, with six different options. Users can also toy with other photography-related features, such as the white balance, ISO, metering, and outdoor visibility.

The Vietnamese source added that the battery will include Near Field Communication capabilities, similar to the Galaxy Nexus device. This is a short-range wireless technology that allows certain devices to talk to one another, but it is primarily used for syncing, transferring data and performing transactions.

When compared side-by-side to its predecessor in the video, the upcoming Galaxy S3 seems to feature a more squared-off design as opposed to the rounder shape of the S2. The soon-to-be released gadget is expected to be a modest upgrade from its predecessor, reports have said.

Samsung has not been reached for comment on the matter, but it's safe to say that nothing will be confirmed until the official unveiling, set to come in the next couple of weeks. However, some believe that this is a clear indication of what's to come.

As for the design, I wouldn't be surprised if this isn't the final look for Samsung's newest toy, writes Luke Westaway of Cnet.

Other rumored features include a 9mm thick body, 32 or 64 GB of internal memory, USB 3.0 capability, and 4G LTE connectivity.
