As with most Android smartphones, the Samsung Galaxy S II comes with Samsung's own patented TouchWiz 4.0 UI, an upgrade from Samsung Galaxy S's TouchWiz 3.0. The latest version of the interface comes with a couple of small tweaks here and there; from sleeker widgets (including more to choose from), to new gesture functionality and improved camera interface.
Productivity apps like Kies Air, Photo editor and Video maker are now made integral to TouchWiz 4.0. Kies Air is not new to the Samsung portfolio of gadgets - like Motorola's Moto Phone Portal app, it allows users to access their phone's content on a web browser through a given URL via a Wi-Fi connection or a self-created Wi-Fi hotspot. From there, you can manage almost everything on your Samsung Galaxy S II.
Users will also see four Hubs, with the Music, Readers and Games Hubs acting like Samsung's own multimedia stores, as well as a Social Hub that collates all your social networking and messaging feeds into one place.
