Iphone 5

The iPhone 5 features iOS, Apple's mobile operating system.^[24] The user interface of iOS is based on the concept of direct manipulation, using multi-touch gestures. Interface control elements consist of sliders, switches, and buttons.^[25] Interaction with the OS includes gestures such as swipe, tap, pinch, and reverse pinch, all of which have specific definitions within the context of the iOS operating system and its multi-touch interface. Internal accelerometers are used by some applications to respond to shaking the device (one common result is the undo command) or rotating it vertically (one common result is switching from portrait to landscape mode)

Design

Apple emphasized the improved build quality of the iPhone 5 at its press event.^[10] The frame used in previous versions was redesigned to use an aluminum composite frame.^[36]The iPhone 4 and iPhone 4S used stainless steel instead of aluminium due to Steve Jobs' preference for the metal which he thought, "looks beautiful when it wears".^[37]

All versions of the iPhone 5 are 18% thinner, 20% lighter, and have 12% less overall volume than its predecessor, the iPhone 4S. The phone's aluminum body is 0.30 in (7.6 mm) thick. Apple at the conference claims it is the thinnest smartphone in the world at 7.6 mm, though that claim has been disputed as the Oppo Finder is thinner and some other smartphones can be considered to be thinner, depending upon where thickness is measured. The Oppo Finder measures 6.65 mm at its thinnest point and 7.1 mm at its thickest point making it overall thinner than the iPhone
