Software
User interface
The phone employs the latest proprietary Samsung TouchWiz 3.0 user interface. Unlike TouchWiz 3.0 on the Samsung Wave, it allows up to seven homescreens. However, different from other Android user interfaces, TouchWiz 3.0 allows users to add, delete and rearrange homescreens. The program launcher is also different from other Android user interfaces in that it has an iOS-like program menu which allows customization of shortcuts. In addition, three of the four shortcuts at the bottom of the screen can also be customized.
The Epic 4G features a specialized version of TouchWiz based on TouchWiz 2.5. Because of the Epic 4G's QWERTY slide-out keyboard, the homescreen needed to be able to rotate into landscape mode, and accordingly several key features and applications are absent on the Epic. TouchWiz 3.0 devices do not support this feature, and because of that difference, the Epic 4G ships with a heavily modified TouchWiz 2.5 interface. The customization of homescreens, as well as several other features found on TouchWiz 3.0 devices like the Vibrant, Captivate, and Fascinate, is not supported in the version of TouchWiz that ships on the Epic 4G.
The most important aspect of all three generations of TouchWiz is the widget interface. The most prominent widgets that come with the Galaxy S are the Daily Briefing, weather clock and the Buddies Now widget. In addition to Samsung widgets, standard Android widgets can be added and removed from the homescreens.
