Well, what do we have here? The Samsung Galaxy S III - or otherwise known as the GT I9300 - has just been officially announced for an unveiling in London on the 3rd of May, but it does look like you don't have to wait that long for a glimpse of the coveted device. Vietnamese site, Tinhte, has already gotten its paws on the smartphone, alleged to be the official device for Olympics 2012.
The video shows a Galaxy smartphone with a 4.6-inch display at 720 x 1184 resolution (320 DPI) placed next to the Samsung Galaxy Nexus for reference. No physical buttons are spotted on this device - only virtual buttons -, clashing with previous intel and images that point to the fact that the smartphone will allegedly showcase a single Home physical button. The video is not well-lit enough to properly discern the phone's build and structure but from what we gather, the Galaxy S III looks a tad bulkier than its popular predecessor, the Samsung Galaxy S II. In this case, we are foreseeing some complaints from potential buyers about its rather hefty build.
Engadget - Other hardware mentions include a 1GB of RAM, 8-megapixel camera, 16GB of storage plus microSD capability. According to Tinhte, the 2050 mAh battery will arrive with NFC capabilities baked in, like the Galaxy Nexus before it.
Here's a video of the plausible Galaxy S III with authentic Vietnamese commentary. We'll leave it up to you to decide if the phone is the real deal or not:
