The Galaxy S3 is Samsung’s another trend-setter. The most noticeable feature is its Smart stay which got it many eyes. The tagline which Samsung set for S3 was “inspired by nature” which fits into every atom. It has many points of attraction for its design and build. Every quality of Galaxy S3 is projected wonderfully with 4.8 inch HD Super AMOLED (1280×720) display.

It doesn’t just stop with the display, the 8MP rear camera with zero shutter lag is perfect for capturing moments and a 1.9 MP front camera for awesome video calling experience. Galaxy S3 inspires colors from nature. It is available in Marble White, Pebble Blue, Amber Brown, Garnet Red, Sapphire Black and Titanium Grey.
