My first Galaxy Smartphone was Samsung galaxy S3. Loved the looks and sleek design. It has some unique features such as S Voice, Social tag, Direct call, Smart stay, Smart alert, S Beam, AllShare Play and AllShare Cast and Buddy photo share.
The smart feature which I like the most is SMART STAY, the feature that was only available in samsung phones. With this feature, the phone automatically recognizes how you are using your phone – reading an e-book or browsing the web, the front camera identify your eyes and the phone maintains a bright display for continued viewing pleasure.
