A smartphone (or smart phone) is a mobile phone with an operating system.[1][2][3] Smartphones typically include the features of a phone with those of another popular consumer device, such as a personal digital assistant, a digital camera, a media player or a GPS navigation unit. Later smartphones include all of those plus a touchscreen interface, broadband internet, web browsing, Wi-Fi, 3rd-party apps, motion sensors and mobile payment mechanisms.
iPhone & Android

In 2007, Apple Inc. introduced the iPhone, one of the first mobile phones to use a multi-touch interface. The iPhone was notable for its use of a large touchscreen for direct finger input as its main means of interaction, instead of a stylus, keyboard, or keypad typical for smartphones at the time.[22] 2008 saw the release of the first phone to use Android called the HTC Dream (also known as the T-Mobile G1).[23][24] Android is an open-source platform founded by Andy Rubin and backed by Google.[25][26] Although Android's adoption was relatively slow at first, it started to gain widespread popularity in 2010, and now dominates the market.

Both of these platforms led to the drop of the previous leading companies. Microsoft, for instance, started a new OS from scratch, in the form of Windows Phone, which is now the third largest OS. Nokia abandoned Symbian and partnered with Microsoft to use Windows Phone on its smartphones. Palm was bought by Hewlett-Packard, turned into webOS which became Open webOS and later sold to LG Electronics. BlackBerry also made a new system from scratch, BlackBerry 10.

The capacitive touchscreen also had a knock-on effect on smartphone form factors. Before 2007 it was common for devices to have a numeric keypad or QWERTY keyboard in either a candybar or sliding form factor. However, by 2010, there were no top-tier smartphones with numeric keypads. As of 2014, BlackBerry Limited – with a 0.6% share of the market in Q4 2013[27] – is the sole remaining brand of high-end smartphones with physical keyboards.
The future

     In 2013, the Fairphone company launched its first "socially ethical" smartphone at the London Design Festival to address concerns regarding the sourcing of materials in the manufacturing.[28]
     In late 2013, QSAlpha commenced production of a smartphone designed entirely around security, encryption and identity protection.[29]
     In December 2013, the world's first curved-OLED technology smartphones were introduced to the retail market with the sale of the Samsung Galaxy Round and LG G Flex models.[30] Samsung phones with more bends and folds in the screens are expected this year.[31]
     Foldable OLED smartphones could be as much as a decade away because of the cost of producing them. There is a relatively high failure rate when producing these screens. As little as a speck of dust can ruin a screen during production. Creating a battery that can be folded is another hurdle.[32]
     A clear thin layer of crystal glass can be added to small screens like watches and smartphones that make them solar powered. Smartphones could gain 15% more battery life during a typical day. The first smartphones using this technology should arrive in 2015. This screen can also work to receive Li-Fi signals and so can the smartphone camera.[33] The cost of these screens per smartphone is between $2 and $3, much cheaper than most new technology.[34]
     Near future smartphones might not have a traditional battery as their sole source of power. Instead, they may pull energy from radio, television, cellular or Wi-Fi signals.[35]
     In early 2014, smartphones are beginning to use Quad HD (2K) 2560x1440 on 5.5" screens with up to 534 ppi on devices such as the LG G3 which is a significant improvement over Apple's retina display. Quad HD is used in advanced televisions and computer monitors, but with 110 ppi or less on such larger displays.[36]
     As of 2014, Wi-Fi networks are much used for smartphones. As Wi-Fi becomes more prevalent and easier to connect to, Wi-Fi phones service will start to take off.[37][38][39]
     Since 2013, water and dustproofing have made their way into mainstream high end smartphones instead of specialist models with the Sony Xperia Z continuing through the Sony Xperia Z3 and also from other manufacturers with the Samsung Galaxy S5.[40]
     One problem with smartphone cameras is still the focus, but LG G3 Beat with Laser Focus has 8 points of focus. To focus what appears in the LCD, touch the object on screen to focus on it and the other positions will be 'bokeh'.[41]
     Some smartphones can be categorized as high-end point-and-shoot cameras with large sensor up to 1" with 20 Megapixels and 4K video. Some can store their pictures in proprietory raw image format, but the Android (operating system) 5.0 lollipop serves open source RAW images.[42][43]
    Modular smartphones are projected, in which users can remove and replace parts.

Android 4.4.2 home screen

Android is an open-source platform founded in October 2003 by Andy Rubin and backed by Google, along with major hardware and software developers (such as Intel, HTC, ARM, Motorola and Samsung) that form the Open Handset Alliance.[25][26] In October 2008, HTC released the HTC Dream, the first phone to use Android.[23][24] The software suite included on the phone consists of integration with Google's proprietary applications, such as Maps, Calendar, and Gmail, and a full HTML web browser. Android supports the execution of native applications and third-party apps which are available via Google Play, which launched in October 2008 as Android Market. By Q4 2010, Android became the best-selling smartphone platform.[44]

The original iPhone (2007)

In 2007, Apple Inc. introduced the iPhone, one of the first mobile phones to use a multi-touch interface. The iPhone was notable for its use of a large touchscreen for direct finger input as its main means of interaction, instead of a stylus, keyboard, or keypad as typical for smartphones at the time.[22] In July 2008, Apple introduced its second generation iPhone with a much lower list price and 3G support. Simultaneously, they introduced the App Store, which allowed any iPhone to install third-party native applications. Featuring over 500 applications at launch,[45] the App Store eventually achieved 1 billion downloads in the first year, and 15 billion by 2011.[46][47]
Windows Phone

BlackBerry Z10 from 2013

In 1999, RIM released its first BlackBerry devices, providing secure real-time push-email communications on wireless devices. Services such as BlackBerry Messenger provide the integration of all communications into a single inbox. There are 80 million active BlackBerry service subscribers and the 200 millionth BlackBerry smartphone was shipped in September 2012.[59] Most recently, RIM has undergone a platform transition, changing its name to BlackBerry and making new devices on a new platform named "BlackBerry 10."[60]
Symbian
Main article: Symbian

Symbian was originally developed by Psion as EPOC32. It was the world's most widely used smartphone operating system until Q4 2010, though the platform never gained popularity or widespread awareness in the U.S., as it did in Europe and Asia. The first Symbian phone, the touchscreen Ericsson R380 Smartphone, was released in 2000,[61][62] and was the first device marketed as a "smartphone".[63] It combined a PDA with a mobile phone.[64] In February 2011, Nokia announced that it would replace Symbian with Windows Phone as the operating system on all of its future smartphones, with the platform getting abandoned throughout the following few years.[65]
