Samsung's Android 4.0 (Ice Cream Sandwich)-powered tablet offers a variety of Android OS features. An upgraded Android Market enables access to more than 400,000 applications which can be enjoyed across phones or tablets. Furthermore, an intuitive user interface includes the ability to swipe-control applications as well as a wholly redesigned app gallery for easier sharing of content. The OS's vastly faster performance and response times across multiple applications is further enhanced by HSPA+ 21 Mbps or WiF-i connectivity. Additionally, Android 4.0 includes a selection of embedded Google applications that enables users to quickly launch sites and applications that they use frequently; meanwhile, the innovative Face Unlock feature unlocks the tablet through unique facial recognition software.
