Smartphones, a combination of "smart" and "telephone," are advanced mobile phones that serve multiple purposes through their powerful hardware capabilities and extensive operating systems. These devices facilitate wider software, internet (including web browsing over mobile broadband), multimedia functionality (music, video, cameras, gaming), and core phone functions like voice calls and messaging. Smartphones often come with various sensors such as magnetometers, proximity sensors, barometers, gyroscopes, and accelerometers that can be leveraged by their software. They also support wireless communication protocols including Bluetooth, Wi-Fi, and satellite navigation. Early smartphones were primarily marketed to the enterprise sector, aiming to bridge the functionality of standalone personal digital assistant devices with cellular telephony. However, they faced limitations such as battery life, bulky form, and immaturity of wireless data services. The 2000s saw BlackBerry, Nokia's Symbian platform, and Windows Phone gain market traction, featuring QWERTY keyboards or resistive touchscreen input, and emphasizing access to push email and wireless internet. Since the launch of the iPhone in 2007, most smartphones have adopted thin, slate-like forms with large capacitive screens supporting multi-touch gestures instead of physical keyboards. They allow users to download additional applications from a centralized store, use cloud storage and synchronization, virtual assistants, and mobile payment services. Improved hardware and faster wireless communication (due to standards like LTE) have fueled the growth of the smartphone industry. In Q3 2012, one billion smartphones were in use worldwide, and global smartphone sales surpassed feature phone sales in early 2013. Smartphone screens fill most or nearly all of a device's front surface, with sizes measured diagonally in inches. Screens larger than 5.2 inches are often called phablets, but may be difficult to use with one hand. However, design advances and taller aspect ratios have improved ergonomics for large-screen smartphones. A wide range of accessories is available for smartphones, including cases, screen protectors, charging cables, USB On-The-Go adapters, add-on batteries, headphones, combined headphone-microphones, and Bluetooth speakers. Cases range from basic rubber or soft plastic to heavy-duty options with rubber padding and hard outer shells. Some cases have book-like designs, providing protection when closed. Manufacturer-hosted online distribution for third-party applications was popularized by Apple's App Store in 2008, leading to the development of a vast variety of apps including games, music products, and business tools.
