Smartphone
A smartphone is a mobile phone with an advanced mobile operating system which combines features of a personal computer operating system with other features useful for mobile or handheld use.[1][2][3] It typically combines the features of a cell phone with those of other popular mobile devices, such as personal digital assistant (PDA), media player, GPS navigation unit and digital camera. Most smartphones can access the Internet and can run third-party apps. They have a touchscreen user interface, with LCD, OLED, AMOLED, LED or similar screen. Smartphones became widespread in the 21st century and most of those produced from 2012 onwards have high-speed mobile broadband 4G LTE, motion sensors, and mobile payment.
History
Early years

Devices that combined telephony and computing were first conceptualized by Nikola Tesla in 1909 and Theodore Paraskevakos in 1971 and patented in 1974, and were offered for sale beginning in 1993. Paraskevakos was the first to introduce the concepts of intelligence, data processing and visual display screens into telephones. In 1971, while he was working with Boeing in Huntsville, Alabama, Paraskevakos demonstrated a transmitter and receiver that provided additional ways to communicate with remote equipment, however it did not yet have general purpose PDA applications in a wireless device typical of smartphones. They were installed at Peoples' Telephone Company in Leesburg, Alabama and were demonstrated to several telephone companies. The original and historic working models are still in the possession of Paraskevakos.[4]
Forerunner

The first mobile phone to incorporate PDA features was an IBM prototype developed in 1992 and demonstrated that year at the COMDEX computer industry trade show. The prototype demonstrated PDA features as well as other visionary apps like maps, stocks and news incorporated with a cellular phone. A refined version of the product was marketed to consumers in 1994 by BellSouth under the name Simon Personal Communicator. The Simon was the first cellular device that can be properly referred to as a "smartphone", although it was not called that in 1994.[6][7][8] In addition to its ability to make and receive cellular phone calls, Simon was able to send and receive faxes and emails and included several other apps like address book, calendar, appointment scheduler, calculator, world time clock, and note pad through its touch screen display. Simon is the first smartphone to be incorporated with the features of a PDA.[9]
The term "smart phone" first appeared in print in 1995, for describing AT&T's "PhoneWriter Communicator" as a "smart phone".[10]
PDAs
In the late 1990s, many mobile phone users carried a separate dedicated PDA device, running early versions of operating systems such as Palm OS, BlackBerry OS or Windows CE/Pocket PC.[1] These operating systems would later evolve into mobile operating systems.
In March 1996, Hewlett-Packard released the OmniGo 700LX, which was a modified 200LX PDA that supported a Nokia 2110-compatible phone and had integrated software built in ROM to support it. The device featured a 640x200 resolution CGA compatible 4-shade gray-scale LCD screen and could be used to make and receive calls, text messages, emails and faxes. It was also 100% DOS 5.0 compatible, allowing it to run thousands of existing software titles including early versions of Windows.
In August 1996, Nokia released the Nokia 9000 Communicator which combined a PDA based on the GEOS V3.0 operating system from Geoworks with a digital cellular phone based on the Nokia 2110. The two devices were fixed together via a hinge in what became known as a clamshell design. When opened, the display was on the inside top surface and with a physical QWERTY keyboard on the bottom. The personal organizer provided e-mail, calendar, address book, calculator and notebook with text-based web browsing, and the ability to send and receive faxes. When the personal organizer was closed, it could be used as a digital cellular phone.
In June 1999, Qualcomm released a "CDMA Digital PCS Smartphone" with integrated Palm PDA and Internet connectivity, known as the "pdQ Smartphone".[11]
In early 2000, the Ericsson R380 was released by Ericsson Mobile Communications,[12] and was the first device marketed as a "smartphone".[13] It combined the functions of a mobile phone and a PDA, supported limited web browsing with a resistive touchscreen utilizing a stylus.[14]
In early 2001, Palm, Inc. introduced the Kyocera 6035, which combined a PDA with a mobile phone and operated on Verizon. It also supported limited web browsing.[15][16]
In 2002, Handspring released the Treo 180, the first smartphone to combine Palm OS and a GSM phone, with telephony, SMS messaging and Internet access fully integrated into Palm OS.[17]
Smartphones before Android, iOS and BlackBerry, typically ran on Symbian, which was originally developed by Psion. It was the world's most widely used smartphone operating system until the last quarter of 2010.[citation needed]
Mass adoption
In 1999, the Japanese firm NTT DoCoMo released the first smartphones to achieve mass adoption within a country. These phones ran on i-mode, which provided data transmission speeds up to 9.6 kbit/s.[18] Unlike future generations of wireless services, NTT DoCoMo's i-mode used cHTML, a language which restricted some aspects of traditional HTML in favor of increasing data speed for the devices. Limited functionality, small screens and limited bandwidth allowed for phones to use the slower data speeds available.[19]
The rise of i-mode helped NTT DoCoMo accumulate an estimated 40 million subscribers by the end of 2001. It was also ranked first in market capitalization in Japan and second globally. This power would wane in the face of the rise of 3G and new phones with advanced wireless network capabilities.[20]
Outside Japan smartphones were still rare until the introduction of the Danger Hiptop in 2002, which saw moderate success in the US as the T-Mobile Sidekick. Later, in the mid-2000s, devices based on Microsoft's Windows Mobile started to gain popularity among business users in the U.S. The BlackBerry later gained mass adoption in the U.S., and American users popularized the term "CrackBerry" in 2006 due to its addictive nature.[21] The company first released its GSM BlackBerry 6210, BlackBerry 6220, and BlackBerry 6230 devices in 2003.[22]
Symbian was the most popular smartphone OS in Europe during the middle to late 2000s. Initially, Nokia's Symbian devices were focused on business, similar to Windows Mobile and BlackBerry devices at the time. From 2006 onwards, Nokia started producing entertainment-focused smartphones, popularized by the Nseries. In Asia, with the exception of Japan, the trend was similar to that of Europe.[citation needed]
Linux, iOS, Android and Windows Phone
In 2003, Motorola launched the first smartphone to use Linux, the A760 handset. [23] While the initial release was limited to a single high-end handset only available in the Asia-Pacific region, the maker's intention was to eventually use Linux on most of its handsets, including the lower-end models. Further models to use Linux such as the Motorola Ming A1200i in 2005 and several successors to the Ming line would be unveiled through 2010. In late 2009, Motorola released the Motorola Cliq [24], the first of Motorola's smart phones to run the Linux-based Android operating system.
In early 2007, Apple Inc. introduced the iPhone, one of the first smartphones 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.[25]
In October 2008, the first phone to use Android called the HTC Dream (also known as the T-Mobile G1) was released.[26][27] Android is an open-source platform founded by Andy Rubin and now owned by Google.[28][29] Although Android's adoption was relatively slow at first, it started to gain widespread popularity in 2010, and in early 2012 dominated the smartphone market share worldwide, which continues to this day.[30]
These new platforms led to the decline of earlier ones. Microsoft, for instance, started a new OS from scratch, called Windows Phone. Nokia abandoned Symbian and partnered with Microsoft to use Windows Phone on its smartphones. Windows Phone then became the third-most-popular OS. Palm's webOS was bought by Hewlett-Packard and later sold to LG Electronics for use on LG smart TVs. BlackBerry Limited, formerly known as Research In Motion, also made a new platform based on QNX, 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 physical numeric keypad or physical QWERTY keyboard in either a candybar or sliding form factor. However, by 2010, there were no top-selling smartphones with physical keypads.
Recent technological developments
- 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.[31]
- In late 2013, QSAlpha commenced production of a smartphone designed entirely around security, encryption and identity protection.[32]
- 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.[33] Samsung phones with more bends and folds in the screens were expected in 2014.[34]
- In early 2014, smartphones were 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.[35]
- As of 2014, Wi-Fi networks were much used for smartphones. As Wi-Fi becomes more prevalent and easier to connect to, Wi-Fi phone services will start to take off.[36][37][38]
- Smartphones are increasingly integrated with everyday uses. For instance, credit cards and mobile payments are integrated into smartphones where users can send cash payments through smartphone applications and SaaS platforms.[39] Recently, Apple Pay has picked up 34 new banks to the roster supporting their mobile payment platform, where merchants are rapidly adopting it.[40] Additionally, recent technological innovations are causing keys to be fused into the smartphones, where the smartphone can act as a digital key and access badge for its users.[41]
- Since 2013, water and dustproofing have made their way into mainstream high end smartphones instead of specialty models with the Sony Xperia Z continuing through the Sony Xperia Z3 and with the Samsung Galaxy S5.[42]
- LG introduced lasers on the LG G3 to help camera focus.[43]
- Some smartphones can be categorized as high-end point-and-shoot cameras with large sensors up to 1" with 20 megapixels and 4K video. Some can store their pictures in proprietary raw image format, but the Android (operating system) 5.0 Lollipop serves open source RAW images.[45][46]
- In October 2015, Microsoft announced Windows Continuum, a feature that allows users to connect their devices to an external monitor via Microsoft Continuum Display Dock.[44] HP adds a layer to the Continuum with their HP Workplace which enables user to run a Win32 app by a virtualized server.[47]
- The first modular smartphone available to the public is the Fairphone 2 and it was released in December 2015; users can remove and replace parts.
Future possible developments
- 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.[48]
- 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.[49]
Mobile operating systems
Android
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, LG, and Samsung) that form the Open Handset Alliance.[28][29] In October 2008, HTC released the HTC Dream, 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.[50]
iOS
![](http://upload.wikimedia.org/wikipedia/en/thumb/d/dc/IOS_9_Homescreen.png/170px-IOS_9_Homescreen.png)
iOS is a mobile operating system developed by Apple Inc. and distributed exclusively for Apple hardware. It is the operating system that powers the company's iDevices. In 2007, Apple introduced the iPhone, the first device to use iOS and one of the first smartphones 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.[25] In 2008, Apple introduced the App Store, which allowed any iPhone to install third-party native applications. Featuring over 500 applications at launch,[51] the App Store eventually achieved 1 billion downloads in the first year, and 75 billion by mid-2014.[52][53] In January 2015, Apple announced that they have now sold one billion iOS devices.[54]
Windows Phone
In 2010, Microsoft unveiled Windows Phone 7 with a User Interface inspired by Microsoft's "Metro Design Language", to replace Windows Mobile. Windows Phone 7 integrates with Microsoft services such as Microsoft SkyDrive, Office, Xbox and Bing, as well as non-Microsoft services such as Facebook, Twitter and Google accounts. This software platform runs the Microsoft Mobile smartphones, and has received some positive reception from the technology press and been praised for its uniqueness and differentiation.[55][56][57] In 2012, Microsoft released Windows Phone 8, replacing its previously Windows CE-based architecture with one based on the Windows NT kernel with many components shared with Windows 8, allowing applications to be ported between the two platforms. In recent version of Windows Phone turn into new series called Windows 10 Mobile , They insert many new things like App porting from Android, iOS, a brand new mobile computing called Windows Continuum which allow users to use full-fledged PC experience by putting a Display, Keyboard and mouse. Also a new Universal Windows Platform has announced by which developer can build any app for every Windows 10 platform with same core API. This version of Windows Phone has a lot of features for developers.[44][58]
BlackBerry
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. In September 2012, RIM announced that the 200 millionth BlackBerry smartphone was shipped. As of September 2014, there are around 46 million active BlackBerry service subscribers.[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] and in November 2015 released an Android smartphone, the BlackBerry Priv.[61]
Firefox OS
Firefox OS (originally called the boot to gecko project) was demonstrated by Mozilla in February 2012. It was designed to have a complete community based alternative system for mobile devices, using open standards and HTML5 applications. The first commercially available Firefox OS phones were ZTE Open and Alcatel One Touch Fire. As of 2014 more companies have partnered with Mozilla including Panasonic (which is making a smart TV with Firefox OS) and Sony.[62]
Sailfish OS
The Sailfish OS is based on the Linux kernel and Mer.[63] Additionally Sailfish OS includes a partially or completely proprietary multi-tasking user interface programmed by Jolla. This user interface differentiate Jolla smartphones from others.[64] Sailfish OS is intended to be a system made by many of the MeeGo team, which left Nokia to form Jolla, utilizing funding from Nokia's "Bridge" program which helps establish and support start-up companies formed by ex-Nokia employees.[65][66][67]
Tizen
Tizen is a Linux-based operating system for devices, including smartphones, tablets, in-vehicle infotainment (IVI) devices, smart TVs, laptops and smart cameras. Tizen is a project within the Linux Foundation and is governed by a Technical Steering Group (TSG) composed of Samsung and Intel among others. In April 2014, Samsung released the Samsung Gear 2 and the Gear 2 Neo, running Tizen.[68] The Samsung Z1 is the first smartphone produced by Samsung that runs Tizen; it was released in the Indian market on January 14, 2015.[69]
Ubuntu Touch
Ubuntu Touch (also known as Ubuntu Phone) is a mobile version of the Ubuntu operating system developed by Canonical UK Ltd and Ubuntu Community.[70] It is designed primarily for touchscreen mobile devices such as smartphones and tablet computers.
Discontinued mobile operating systems
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,[71][72] and was the first device marketed as a "smartphone".[73] It combined a PDA with a mobile phone.[74] Variants of Symbian OS began to emerge, most notably Symbian UIQ, MOAP and S60, each supported by different manufacturers. With the creation of Symbian Foundation in 2008, Symbian OS was unified under one variant under the stewardship of Nokia. 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.[75]
Windows Mobile
Windows Mobile was based on the Windows CE kernel and first appeared as the Pocket PC 2000 operating system. Throughout its lifespan, the operating system was available in both touchscreen and non-touchscreen formats. It was supplied with a suite of applications developed with the Microsoft Windows API and was designed to have features and appearance somewhat similar to desktop versions of Windows. Third parties could develop software for Windows Mobile with no restrictions imposed by Microsoft. Software applications were eventually purchasable from Windows Marketplace for Mobile during the service's brief lifespan. Windows Mobile was phased out in favor of Windows Phone.
Bada
The Bada operating system for smartphones was announced by Samsung in November 2009.[76][77] The first Bada-based phone was the Samsung Wave S8500, released in June 2010.[78][79] Samsung shipped 4.5 million phones running Bada in Q2 of 2011.[80] In 2013, Bada merged with a similar platform called Tizen.
Palm OS
In late 2001, Handspring launched the Springboard GSM phone module with limited success. In May 2002, Handspring released the Palm OS Treo 270 smartphone, that did not support Springboard, with both a touchscreen and a full keyboard. The Treo had wireless web browsing, email, calendar, a contact organizer and mobile third-party applications that could be downloaded or synced with a computer.[81] Handspring was purchased by Palm, Inc which released the Treo 600 and continued releasing Treo devices with a few Treo devices using Windows Mobile. After buying Palm in 2011, Hewlett-Packard (HP) discontinued its webOS smartphone and tablet production.[82]
webOS
webOS is a proprietary mobile operating system running on the Linux kernel, initially developed by Palm, which launched with the Palm Pre. After being acquired by HP, two phones (the Veer and the Pre 3) and a tablet (the TouchPad) running webOS were introduced in 2011. On August 18, 2011, HP announced that webOS hardware was to be discontinued[83] but would continue to support and update webOS software and develop the webOS ecosystem.[84] HP released webOS as open source under the name Open webOS, and plans to update it with additional features.[85] On February 25, 2013 HP announced the sale of WebOS to LG Electronics, who used the operating system for its current "smart" or Internet-connected TVs, but not smartphones. In January 2014, Qualcomm has announced that it has acquired technology patents from HP, which includes all the WebOS patents.[86]
Maemo / MeeGo
MeeGo is an operating system created from the source code of Moblin (produced by Intel) and Maemo (produced by Nokia). Before that, Nokia used Maemo on some of its smartphones and internet tablets (such as Nokia N810 and N900). MeeGo was originally envisioned to power a variety of devices from netbooks, tablets to smartphones and smart TVs. However, the only smartphones which used MeeGo was the Nokia N9 and Nokia N950 (MeeGo v1.2 Harmattan). Following Nokia's decision to move to Windows Phone OS in 2011 and to cease MeeGo development, the Linux Foundation canceled MeeGo in September 2011 in favor of the development of Tizen.
Application stores
The introduction of Apple's App Store for the iPhone and iPod Touch in July 2008 popularized manufacturer-hosted online distribution for third-party applications (software, computer programs) focused on a single platform. Up until that point, smartphone application distribution depended on third-party sources providing applications for multiple platforms, such as GetJar, Handango, Handmark, and PocketGear.
Following the success of the App Store, other smartphone manufacturers launched application stores, such as Google's Android Market in October 2008 and RIM's BlackBerry App World in April 2009. In February 2014, 93% of mobile developers were targeting smartphones first for mobile app development.[87]

One of the main characteristics of smartphones is their screen. It usually fills most of the phone's front surface (about 70%); screen size usually defines the size of a smartphone. Many have an aspect ratio of 16:9; some are 4:3 or other ratios.
They are measured in diagonal inches, starting from 2.45 inches.[88] Phones with screens larger than 5.2 inches are often called "phablets". Smartphones with screens over 4.5 inches commonly are shifted while using a single hand, since most thumbs cannot reach the entire screen surface, or used in place with both hands. Liquid-crystal displays are the most common; others are IPS, LED, OLED, AMOLED and E Ink displays.
An upcoming development is a Braille screen, using microfluidics technology.[89]
Market share
Smartphone usage
In the third quarter of 2012, one billion smartphones were in use worldwide.[90] Global smartphone sales surpassed the sales figures for features phones in early 2013.[91] As of 2013, 65 percent of U.S. mobile consumers own smartphones.[92] The European mobile device market as of 2013 is 860 million.[93] In China, smartphones represented more than half of all handset shipments in the second quarter of 2012[94] and in 2014 there were 519.7 million smartphone users, with the number estimated to grow to 700 million by 2018.[95]
As of November 2011, 27% of all photographs were taken with camera-equipped smartphones.[96] A study conducted in September 2012 concluded that 4 out of 5 smartphone owners use the device to shop.[97] Another study conducted in June 2013 concluded that 56% of American adults now owned a smartphone of some kind. Android and iPhone owners account for half of the cell phone user population. Higher income adults and those under age 35 lead the way when it comes to smartphone ownership.[98]
Worldwide shipments of smartphones topped 1 billion units in 2013, up 38% from 2012's 725 million, while comprising a 55% share of the mobile phone market in 2013, up from 42% in 2012.[99]
Since 1996 smartphone shipments have had positive growth, but in Q1 2016 for the first time the shipments dropped by 3 percent year on year. The situation was caused by mature China market.[100]

Issues
Smartphones have presented issues besides those affecting other mobile telephones.
Battery life
![](http://upload.wikimedia.org/wikipedia/commons/thumb/c/c0/Cheero_powerbank_%26_Samsung_Galaxy_S4_20140910.jpg/220px-Cheero_powerbank_%26_Samsung_Galaxy_S4_20140910.jpg)
Compared to earlier non-smartphones, smartphone battery life has generally been poor and a significant drain on customer satisfaction.[119][120][121] There is also a trend to batteries that the user cannot replace. [122]
Social
A 2012 University of Southern California study found that unprotected adolescent sexual activity was more common among owners of smartphones.[123] A study conducted by the Rensselaer Polytechnic Institute's (RPI) Lighting Research Center (LRC) concluded that smartphones, or any backlit devices, can seriously affect sleep cycles.[124] Some persons might become psychologically attached to cellphones resulting in anxiety when separated from the devices.[125]
A "smombie" (a combination of "smartphone" and "zombie") is a walking person using a smartphone and not paying attention as they walk, possibly risking an accident in the process, an increasing social phenomenon.[126] The issue of slow-moving smartphone users led to the temporary creation of a "mobile lane" for walking in Chongqing, China.[127] The issue of distracted smartphone users led the city of Augsburg, Germany to embed pedestrian traffic lights in the pavement.[128]
Legal
A "patent war" between Samsung and Apple started when the latter claimed that the original Galaxy S Android phone copied the interface—and possibly the hardware—of Apple's iOS for the iPhone 3GS.
Medical
With the rise in number of mobile medical apps in the market place, government regulatory agencies raised concerns on the safety of the use of such applications. These concerns were transformed into regulation initiatives worldwide with the aim of safeguarding users from untrusted medical advice.[129]
Security
Smartphone malware is easily distributed through an insecure app store.[130][131] Often malware is hidden in pirated versions of legitimate apps, which are then distributed through third-party app stores.[132][133] Malware risk also comes from what's known as an "update attack", where a legitimate application is later changed to include a malware component, which users then install when they are notified that the app has been updated.[134]
One out of three robberies in 2012 in the United States involved the theft of a mobile phone. An online petition has urged smartphone makers to install kill switches in their devices.[135] In 2014, Apple's "Find my iPhone" and Google's "Android Device Manager" can disable phones that have been lost/stolen. With BlackBerry Protect in OS version 10.3.2, devices can be rendered unrecoverable to even BlackBerry's own Operating System recovery tools if incorrectly authenticated or dissociated from their account.[136]
Sleep
Using smartphones late at night can disturb sleep, due to the brightly lit screen affecting melatonin levels and sleep cycles.[137][138][139][140] Apple is attempting to mitigate this beginning in iOS 9.3 with the introduction of Night Shift. Night Shift changes the screen color levels to a warmer hue and reduces blue light. This change is intended to help users fall asleep easier as the reduced blue light should have less effect on their circadian rhythms. Night Shift can be turned on manually, or set to turn on automatically between sunset and sunrise.[citation needed]
Other terms
"Phablet", a portmanteau of the words phone and tablet, describes smartphones with larger screens.[141][142]
"Superphone" is also used by some companies to market phones with unusually large screens and other expensive features.[143][144]
