<P> The S III is powered by Android, a Linux - based, open source mobile operating system developed by Google and introduced commercially in 2008 . Among other features, the software allows users to maintain customized home screens which can contain shortcuts to applications and widgets for displaying information . Four shortcuts to frequently used applications can be stored on a dock at the bottom of the screen; the button in the center of the dock opens the application drawer, which displays a menu containing all of the apps installed on the device . A tray accessed by dragging from the top of the screen allows users to view notifications received from other apps, and contains toggle switches for commonly used functions . Pre-loaded apps also provide access to Google's various services . The S III uses Samsung's proprietary TouchWiz graphical user interface (GUI). The "Nature" version used by the S III has a more "organic" feel than previous versions, and contains more interactive elements such as a water ripple effect on the lock screen . To complement the TouchWiz interface, and as a response to Apple's Siri, the phone introduces S Voice, Samsung's intelligent personal assistant . S Voice can recognize eight languages including English, Korean, Italian and French . Based on Vlingo, S Voice enables the user to verbally control 20 functions such as playing a song, setting the alarm, or activating driving mode; it relies on Wolfram Alpha for online searches . </P> <P> The S III initially shipped with Android version 4.0. 4, named "Ice Cream Sandwich", which became commercially available in March 2012 with the Nexus S and Galaxy Nexus . Ice Cream Sandwich has a refined user interface, and expanded camera capabilities, security features and connectivity . In mid-June 2012, Google unveiled Android 4.1 "Jelly Bean", which employs Google Now, a voice - assistant similar to S Voice, and incorporates other software changes . Samsung accommodated Jelly Bean in the S III by making last - minute hardware changes to the phone in some markets . Jelly Bean updates began rolling out to S IIIs in selected European countries, and to the T - Mobile in the United States in November 2012 . Samsung started pushing Android 4.1. 2 Jelly Bean to the international version of the S III in December 2012 . In December 2013, Samsung began rolling out Android 4.3 for the S III, adding user interface features back ported from the Galaxy S4, and support for the Samsung Galaxy Gear smartwatch . In March 2014, Samsung started the rollout of 4.4. 2 KitKat for the 2 GB variant of the S III . </P> <P> The S III comes with a multitude of pre-installed applications, including Google Apps like Google Play, YouTube, Google+, Gmail, Google Maps, Voice Search and Calendar, in addition to Samsung - specific apps such as ChatON, Game Hub, Music Hub, Video Hub, Social Hub and Navigation . To address the fact that iPhone users are reluctant to switch to Android because the OS is not compatible with iTunes, from June 2012 Samsung offered customers of its Galaxy series the Easy Phone Sync app to enable the transfer of music, photos, videos, podcasts, and text messages from an iPhone to a Galaxy device . The user is able to access Google Play, a digital - distribution multimedia - content service exclusive to Android, to download applications, games, music, movies, books, magazines, and TV programs . </P> <P> Apart from S Voice, Samsung has directed the bulk of the S III's marketing campaign towards the device's "smart" features, which facilitate improved human - device interactivity . These features include: "Direct Call", or the handset's ability to recognise when a user wants to talk to somebody instead of messaging them, if they bring the phone to their head; "Social Tag", a function that identifies and tags people in a photo and shares photos with them; and "Pop Up Play", which allows a video and other applications to occupy the screen at the same time . In addition, the S III can beam its screen to a monitor or be used as a remote controller (AllShare Cast and Play) and share photos with people who are tagged in them (Buddy Photo Share). </P>
