A picture of what looks like a slide from a corporate presentation was leaked showing the Samsung Galaxy S3 (or S III as Samsung would put it), the followup to the Samsung Galaxy S2.

The slide, which appears to come from Weber Shandwick Worldwide, the PR agency in charge of the Samsung account globally, shows a redesigned Samsung Galaxy S3 handset with a white facia but a black bezel that's extremely thin on the sides.

The home screen leaves us to believe that the phone will be released on the 22nd of May 2012, which happens to be a Tuesday, between 1800 and 1900 via a live broadcast at a dedicated Galaxy S III unpacked event that has yet to be announced.

The fact that the home screen - out of seven possible screens - also shows London could be purely coincidental. Apart from a physical front facing button, massive speaker grill (a la HTC), a dedicated camera button and a rather large bulging camera sensor, there's not much that can be inferred.

It's worth noting that unlike the previous Samsung Galaxy S2 smartphone, the S3 on the slide appears to be uniformly flat and extremely thin.

Past rumours regarding the S3 have included a launch on the 15th of March (which didn't happen), a quad core processor, a full HD 4.8-inch capacitive display and a ceramic case.
