The Brazilian branch of Gizmodo took these sneaks snaps of the purported Galaxy S III. The quality is dire, owing to the fact that the images were taken with an iPad.
The website even nabbed the serial number, “Samsung GT-I9300” which points to a phone other than the S III, according to this site. So what we have here is a phone that may or may not be the S III. Funnily enough, the crappy images are fairly close to this one, a leaked press shot of the S III.
You be the judge. Or just hang on until 3 May for the S III launch.
