The Smartphone

Smartphones is a class of mobile phones that are used for multi-purposes mobile computing devices. Smartphones are distinguished from other feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software, internet such as web browsing over mobile broadband, and multimedia functionality which include music, video, cameras, and gaming, alongside core phone functions such as voice calls and text messaging.

The early smartphones were marketed primarily towards the venture market, attempting to bridge the functionality of standalone personal digital assistant (PDA) devices with support for cellular telephony, but were limited by their battery life, bulky form, and the immaturity of wireless data services.

In the 2000s, BlackBerry, Nokia's Symbian platform, and Windows Mobile began to gain market traction, with models often featuring QWERTY keyboards or resistive touchscreen input, and emphasizing access to push email and wireless internet. Since the unveiling of the iPhone in 2007, the majority of smartphones have featured thin, slate-like form factors, with large, capacitive screens with support for multi-touch gestures rather than physical keyboards.
Smartphones has various sensors that can be leveraged by their software, such as a magnetometer, proximity sensors, barometer, gyroscope and accelerometer, and they support wireless communications protocols such as, Wi-Fi, Bluetooth and satellite navigation.

Improved hardware and faster wireless communication (due to standards such as LTE) have bolstered the growth of the smartphone industry. In the third quarter of 2012, one billion smartphones were in use worldwide.Global smartphone sales surpassed the sales figures for feature phones in early 2013.
