Samsung Galaxy S3: software, Touchwiz 5
For an in-depth analysis of the software in the Samsung Galaxy S3 you can have a look at our review here. In a nutshell, Samsung is sticking with the tried-and-true TouchWiz look and feel. People familiar with other Samsung Android phones such as the S2 will feel right at home and will be able to navigate the phone easily. Many of the changes in appearance that Google implemented in Andoid 4.0, Samsung has removed. The manufacturer also kept its familiar keyboard lay-out. In addition to the physical home button below the screen, there is a capacitive back button and menu button.
Samsung also added new features to the Galaxy S3, which it likes to called a phone "designed for humans". The implication is that the phone is supposed to be as user-friendly as possible. When you are text-messaging someone, and raise the phone to your ear, it will automatically dial-up that person. The Smart Stay feature ensures that the display stays turned on as long as you are looking at the phone. S Voice provides speech control, but as of yet isn't as streamlined as Apple's Siri.
