Smartphone

A smartphone is a handheld mobile device that combines the functions of a mobile phone with additional features such as an operating system, web browsing, and the ability to run mobile applications.

The history of the smartphone began in the late 1990s with the introduction of devices that combined mobile phone functionality with PDA features. Notable early smartphones include the IBM Simon (1994), Nokia Communicator (1996), and BlackBerry devices (1999). The modern smartphone era started with the release of the Apple iPhone in 2007, which popularized the touchscreen interface and app store model. Since then, smartphones have evolved significantly, incorporating advanced cameras, larger screens, and more powerful processors.

There are several types of smartphones, primarily categorized by the operating system they use:

• iOS: Developed by Apple, known for its user-friendly interface and seamless integration with other Apple devices.
• Android: Developed by Google, known for its open-source nature and wide variety of devices from different manufacturers.
• Windows Phone: Developed by Microsoft, though it has been discontinued and replaced by Windows 10 Mobile.
• BlackBerry OS: Developed by BlackBerry, known for its security features and keyboard input, though it has largely been phased out.
• Other proprietary systems: Some manufacturers have developed their own operating systems, such as Tizen by Samsung and KaiOS by KaiOS Technologies.
