Galaxy S III rear camera
The smartphone runs Android 4.0, the most recent version, which is also known as Ice Cream Sandwich. However, Samsung has tweaked the Google-backed mobile OS to include an overhauled version of its TouchWiz interface, as well as several manufacturer-specific apps designed to make using the phone a more hands-off experience.
One of these features is S Voice, which lets the owner control the handset with voice commands. For example, people can tell it to wake up, place a phone call, make a diary entry, send a text message, take a photo, play music or adjust the volume, all without touching the phone.
Another feature is Smart Stay, which detects when the user is browsing a web page or reading an e-book, and keeps the screen awake without the need to press it.
