A smartphonne
is a mobile phone with
more advanced computing capability and connectivity than basic feature phones. Early smartphones typically
combined the features of a mobile phone with those of another popular consumer
device, such as a personal digital
assistant (PDA), a media player,
a digital camera, or a GPS navigation unit. Modern smartphones
include all of those features plus the features of a touchscreen computer,
including web browsing, Wi-Fi,
and 3rd-party apps and accessories.
The most popular smartphones today are powered by Google's Android and Apple's iOS mobile operating
systems
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. 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 device that can
be properly referred to as a "smartphone", even though that term was
not yet coined. In addition to its ability to make and receive
cellular phone calls, Simon was also able to send and receive faxes and e-mails through its touch screen
display.
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 In late 2013,
QSAlpha commenced production of a smartphone designed entirely around security,
encryption and identity protection. 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. 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. Samsung fully foldable phones are expected to debut in the
2016-2017 timeframe 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. This 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. The cost of these screens per smartphone is between $2 and $3, much
cheaper than most new technology. 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. In early 2014, smartphones are beginning to
use Quad HD (4K)
2560x1440 on 6" screens with up to 490 ppi 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.
In 2014, Wi-Fi will continue to become the primary network
for smartphones. As these devices do more and more with data and Wi-Fi becomes
more prevalent and easier to connect to, Wi-Fi First smartphones service will
start to take off.
In February 2014, some smartphones are dustproof and
waterproof up to one-meter underwater depth such as Samsung Galaxy S5, Sony Xperia Z1S and Sony Xperia Z2
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 and Samsung) that form the Open Handset Alliance.In
October 2008, HTC released the HTC Dream, the first phone to use AndroidThe
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.
Bada
The Bada operating system for smartphones was
announced by Samsung in November 2009.The first Bada-based phone was the Samsung Wave S8500, released in June 2010. Samsung
shipped 4.5 million phones running Bada in Q2 of 2011.[In 2013, Bada merged with a similar platform called Tizen
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. There are 80 million active BlackBerry
service subscribers and the 200 millionth BlackBerry smartphone was shipped in
September 2012Most recently, RIM has undergone a platform transition, changing
its name to BlackBerry and making new devices on a new platform named
"BlackBerry 10."
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.
iOS
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]n 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, the
App Store eventually achieved 1 billion downloads in the first year, and 15
billion by 201[
Palm OS
In late 2001, Handspring launched their own
Springboard GSM phone module with limIn early 2002, Handspring released
the Palm OS Treo smartphone with both a touch screen
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.[Handspring
was soon acquired by Palm, which released the Treo 600 and continued, though
the series eventually took on Windows Mobile. After buyingPalm, Inc, in 2011 Hewlett-Packard (HP) finally discontinued
its smartphones and tablets production using webOS which
is initial developed by Palm, Inc.
Sailfish OS
The Sailfish OS is based on the Linux kernel and Mer.[54] Additionally Sailfish OS
includes a partially or completely proprietary multi-tasking user interface programmed byJolla.
This user interface differentiate Jolla smartphones from others.[55] 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.[
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,[59][60] and was the first device
marketed as a "smartphone".[61] It combined a PDA with a
mobile phone.[62] 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.[63]
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 Phone
In February 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
on most Nokia smartphones, it has received some positive reception from the
technology press and been praised for its uniqueness and differentiation
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.
Security
Smartphone malware is more easily distributed
through application stores that have minimal or no security mechanisms.[100][101] Often
malware is hidden in pirated versions of
legitimate apps, which are then distributed through 3rd party app stores.[102][103] 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.[104]
One out of three robberies involve the theft of
a mobile phone. An online petition urging that smartphone makers to install kill switches in
their devices is underway.[105]
In order to minimize the chances of being a
victim of theft of mobile devices, there have been several apps created to help
those out that may be in a dangerous situation. There are now apps that may aid
in personal security by providing immediate assistance. Although, some personal
security apps may be seen as just for women, they were originally developed to
decrease the risk of sexual assaults and thefts aimed towards students on
school campuses.
