Looks like the Samsung Galaxy S III release date will be in June 2012. Samsung had the press conference May 3, 2012 in London where they launched the Galaxy S 3.
The UK will get the Galaxy S 3 first then North America, Japan and Korea.
The newest Samsung phone will come in two flavors, Blue and White. GS3 weighs in at 133g (4.7 ounces) and 8.6mm thick, Sporting 1.4GHz Exynos 4 Quad processor with 1GB of RAM . The display is a 4.8-inch HD Super AMOLED screen with 1280 x 720 pixels. Galaxy s III also has a 8-megapixel rear facing camera, and a 1.9-megapixel front camera. The rear facing camera can also capture full HD 1080 videos.
Some new and interesting features from Samsung Phones like a Apple kinda Siri-like S Voice recognition feature that understands eight languages and can search for information, show you the weather forecast, organize family schedules. There's also Social Tag, which keeps track of the people close to you and recognizes the faces of your friends in your photos, this means when you take a photo it'll recognize who it is, so you can hit a Facebook button and it'll take you straight to their wall to upload. Cool stuff. Also the front camera would identify the user's eyes and will not go dark or lock as long as they were looking into the screen/camera.
The Samsung Galaxy S3 will be available in 145 countries with 296 mobile operators and the 3G handset will be launched on the 29th of May in Europe, the 30th of May in the UK, and the 4G will be arriving North America, Japan and Korea in June.
