Microsoft
for smartphones as the replacement successor to Windows Mobile[6][7] and Zune.[8] Windows
Windows
Phone features a new user interface derived from Metro design language. Unlike Windows
Windows

History[edit] Development[edit] Work on a major Windows Mobile
Windows Mobile
update may have begun as early as 2004 under the codename "Photon", but work moved slowly and the project was ultimately cancelled.[15] In 2008, Microsoft
Microsoft
reorganized the Windows Mobile group and started work on a new mobile operating system.[16] The product was to be released in 2009 as Windows
Windows
Phone, but several delays prompted Microsoft
Microsoft
to develop Windows Mobile
Windows Mobile
6.5 as an interim release.[17] Windows
Windows
Phone was developed quickly. One result was that the new OS would not be compatible with Windows Mobile
Windows Mobile
applications. Larry Lieberman, senior product manager for Microsoft's Mobile Developer Experience, told eWeek: "If we'd had more time and resources, we may have been able to do something in terms of backward compatibility."[18] Lieberman said that Microsoft
Microsoft
was attempting to look at the mobile phone market in a new way, with the end user in mind as well as the enterprise network.[18] Terry Myerson, corporate VP of Windows
Windows
Phone engineering, said, "With the move to capacitive touch screens, away from the stylus, and the moves to some of the hardware choices we made for the Windows Phone 7
Windows Phone 7
experience, we had to break application compatibility with Windows Mobile
Windows Mobile
6.5."[19] Latest Version of Windows

Windows 10 Mobile
was announced, [20] on October 8 2017, that it no longer receive system features updates, but it will continue to receive security updates. With the company gradually changing its focus from Windows
Windows
Phone to VR and Surface lineup, Microsoft
Microsoft
is no longer developing new features or new hardware for mobile operating system. Existing supported phones will receive bug fixes and security updates as the platform is switching into maintenance mode.[21] Partnership with Nokia[edit] Main article: Microsoft

Microsoft
CEO Steve Ballmer and Nokia
Nokia
CEO Stephen Elop
Stephen Elop
announced a partnership between their companies in which Windows
Windows
Phone would become the primary smartphone operating-system for Nokia, replacing Symbian.[22] The event focused largely on setting up "a new global mobile ecosystem", suggesting competition with Android and iOS with the words "It is now a three horse race". Elop stated the reason for choosing Windows
Windows
Phone over Android, saying: "the single most important word is 'differentiation'. Entering the Android environment late, we knew we would have a hard time differentiating."[23] While Nokia
Nokia
would have had more long-term creative control with Android (note that MeeGo
MeeGo
as used by Nokia
Nokia
resembles Android more than it does Windows Phone 7
Windows Phone 7
as both Android and MeeGo
MeeGo
are based on the Linux
Linux
kernel), Elop enjoyed familiarity with his past company where he had been a top executive.[24][25] The pair announced integration of Microsoft
Microsoft
services with Nokia's own services; specifically:[22]

Bing would power search across Nokia
Nokia
devices integration of Nokia
Nokia
Maps with Bing Maps integration of Nokia's Ovi store with the Windows
Windows
Phone Store

The partnership involves "funds changing hands for royalties, marketing and ad-revenue sharing", which Microsoft
Microsoft
later announced as "measured in billions of dollars."[26] Jo Harlow, whom Elop tapped to run Nokia's smartphone business, rearranged her team to match the structure led by Microsoft's VP of Windows
Windows
Phone, Terry Myerson. Myerson was quoted as saying, "I can trust her with what she tells me. She uses that same direct and genuine communication to motivate her team."[27] The first Nokia

Microsoft
announced a deal to acquire Nokia's mobile phone division outright, retaining former CEO Stephen Elop
Stephen Elop
as the head of Microsoft's devices operation.[33][34] Microsoft
Microsoft
managers revealed that the acquisition was made because Nokia
Nokia
was driving the development of the Windows
Windows
Phone platform to better match their products.[35] The merger was completed after regulatory approval in all major markets in April 2014. As a result, Nokia's hardware division is now a subsidiary of Microsoft
Microsoft
operating under the name Microsoft
Microsoft
Mobile. In February 2014, Nokia
Nokia
released the Nokia
Nokia
X series of smartphones, (later discontinued) using a version of Android forked from the Android Open Source Project. The operating system was modified; Google's software was not included in favour of competing applications and services from Microsoft

Windows 10 Mobile
was announced on January 21, 2015, as a mobile operating system for smartphones and tablets running on ARM architecture. Its primary focus is unification with Windows
Windows
10, its PC counterpart, in software and services; in accordance with this strategy, the Windows
Windows
Phone name has been phased out in favor of branding the platform as an edition of Windows
Windows
10,[49][50][51][52] although it is still a continuation of Windows
Windows
Phone, and most Windows Phone 8.1 devices can be upgraded to the platform.[53][54][55] Windows 10 Mobile
Windows 10 Mobile
emphasizes software using the Universal Windows Platform, which allows apps to be designed for use across multiple Windows
Windows
10-based product families with nearly identical code and functionality, and adaptations for available input methods.[56][57][58] When connected to an external display, devices can also render a stripped-down desktop interface similar to Windows on PCs, with support for keyboard and mouse input.[59][60] Windows

with limited changes to code.[63][64][65] Features[edit] User interface[edit] Windows
Windows
Phone features a user interface based on Microsoft's "Metro" design language,[66] and was inspired by the user interface in the Zune
Zune
HD.[67] The home screen, called the "Start screen", is made up of "Live Tiles", which have been the inspiration for the Windows 8
Windows 8
live tiles. Tiles are links to applications, features, functions and individual items (such as contacts, web pages, applications or media items). Users can add, rearrange, or remove tiles.[68] Tiles are dynamic and update in real time – for example, the tile for an email account would display the number of unread messages or a tile could display a live update of the weather.[69] Since Windows
Windows
Phone 8, live tiles can also be resized to either a small, medium, or large appearance. Several features of Windows
Windows
Phone are organized into "hubs", which combine local and online content via Windows
Windows
Phone's integration with popular social networks such as Facebook, Windows
Windows
Live, and Twitter.[69] For example, the Pictures hub shows photos captured with the device's camera and the user's Facebook
Facebook
photo albums, and the People hub shows contacts aggregated from multiple sources including Windows
Windows
Live, Facebook, and Gmail. From the hub, users can directly comment and 'like' on social network updates. The other built-in hubs are Xbox Music
Xbox Music
and Video, Xbox Live
Xbox Live
Games, Windows
Windows
Phone Store, and Microsoft
Microsoft
Office.[69] Windows
Windows
Phone uses multi-touch technology.[69] The default Windows Phone user interface has a dark theme that prolongs battery life on OLED
OLED
screens as fully black pixels do not emit light. Alternatively, users may choose a light theme in their phone's settings menu.[70] The user may also choose from several accent colors.[71] User interface elements such as links, buttons and tiles are shown in the user's chosen accent color. Third-party applications can be automatically themed with these colors.[72] Windows Phone 8.1
Windows Phone 8.1
introduces transparent tiles and a customizable background image for the Start screen. The image is visible through the transparent area of the tiles and features a parallax effect when scrolling which gives an illusion of depth. If the user does not pick a background image the tiles render with the accent color of the theme. Text input[edit] Users input text by using an on-screen virtual keyboard, which has a dedicated key for inserting emoticons,[73] and features spell checking[73] and word prediction.[74] App developers (both inhouse and ISV) may specify different versions of the virtual keyboard in order to limit users to certain character sets, such as numeric characters alone. Users may change a word after it has been typed by tapping the word,[75] which will invoke a list of similar words. Pressing and holding certain keys will reveal similar characters. The keys are somewhat larger and spaced farther apart when in landscape mode. Phones may also be made with a hardware keyboard for text input.[76] Users can also add accents to letters by holding on an individual letter. Windows Phone 8.1
Windows Phone 8.1
introduces a new method of typing by swiping through the keyboard without lifting the finger, in a manner similar to Swype
Swype
and SwiftKey. Web browser[edit] See also: Internet Explorer Mobile Internet Explorer on Windows
Windows
Phone allows the user to maintain a list of favorite web pages and tiles linking to web pages on the Start screen. The browser supports up to 6 tabs, which can all load in parallel.[77] Other features include multi-touch gestures, smooth zoom in/out animations, the ability to save pictures that are on web pages, share web pages via email, and support for inline search which allows the user to search for a word or phrase in a web page by typing it.[78] Tabs are synced with Windows 8.1
Windows 8.1
devices using Internet Explorer 11. Contacts[edit] Contacts are organized via the "People hub", and can be manually entered into contacts or imported from Facebook, Windows
Windows
Live Contacts, Twitter, LinkedIn, Google, and Outlook. A "What's New" section shows a user's Facebook
Facebook
news feed and a "Pictures" section show pictures from those social networks, while a "Me" section within the "People" hub shows a user's own social network status and wall and allows them to view social network updates. Contacts can also be pinned to the Start Screen. The contact's "Live Tile" displays their social network status and profile picture on the homescreen. Clicking on a contact's tile or accessing their card within the "People" hub will reveal their recent social network activity as well as the rest of their contact information. If a contact has information stored on multiple networks, users can link the two separate contact accounts, allowing the information to be viewed and accessed from a single card.[79] As of Windows
Windows
Phone 7.5, contacts can also be sorted into "Groups". Here, information from each of the contacts is combined into a single page which can be accessed directly from the Hub or pinned to the Start screen. Email[edit] Main article: Mail (Windows) Windows
Windows
Phone supports Outlook.com, Exchange, Yahoo! Mail
Yahoo! Mail
and Gmail natively and supports many other services via the POP and IMAP protocols. Updates added support for more services such as iCloud and IBM Notes Traveler. Contacts and calendars may be synced from these services as well. Users can also search through their email by searching in the subject, body, senders, and receivers. Emails are shown with threads, and multiple email inboxes can be combined into a single view (a feature commonly referred to as "combined inbox") or can viewed separately. Multimedia[edit]

gestures permit zooming in and out of photos. An official file manager app called Files, which is available for download from the Windows
Windows
Phone Store, enables users to move and rearrange documents, videos, music and other files within their device's hard drive or to an external SD card.[82] Media support[edit] Windows
Windows
Phone supports WAV, MP3, WMA, AMR, AAC/MP4/M4A/M4B and 3GP/3G2 standards. The video file formats supported on WP include WMV, AVI, MP4/M4V, 3GP/3G2 and MOV (QuickTime) standards.[83] These supported audio and video formats would be dependent on the codecs contained inside them. It has also been previously reported that the DivX
DivX
and Xvid
Xvid
codecs within the AVI file format are also playable on WP devices.[84][85] Note that Windows
Windows
Phone does not support DRM protected media files that are obtained from services other than Xbox Music
Xbox Music
Pass.[86] The image file formats that are supported include JPG/JPEG, PNG, GIF, TIF and Bitmap (BMP).[87][88] Users can also add custom ringtones which are less than 1MB in size and less than 40 seconds long. DLNA streaming and steroscopic 3D are also supported.[81] Games[edit] Main article: List of Xbox Live

The hub also features an area for managing invitations and turn notifications in turn-based multiplayer games.[89] Games are downloaded from Windows Phone Store. Search[edit] See also: Bing (search engine), Bing Mobile, and Bing Maps Bing is the default search engine on Windows
Windows
Phone handsets because its functions are deeply integrated in the OS (which also include the utilization of its map service for location-based searches and queries). However, Microsoft

devices will be manufactured by Celkon, Gionee, HTC, Huawei, JSR, Karbonn, LG, Lenovo, Longcheer, Micromax, Microsoft Mobile, Samsung, Xolo, and ZTE

among others.[117] Sony
Sony
(under the Xperia or Vaio brand) has also stated its intention to produce Windows Phone devices in the near future.[118] Yezz announced two smartphones in May, and at Computex 2014 BYD, Compal, Pegatron, Quanta and Wistron were also named as new Windows
Windows
Phone OEMs.[119] In August 2014, Huawei
Huawei
said it was dropping support for Windows

Engadget
and ZDNet applauded the integration of Facebook

into the People Hub as well as other built-in capabilities, such as Windows

Windows Phone 7
Windows Phone 7
(2010–2012)[edit] According to Gartner, there were 1.6 million devices running Microsoft OS sold to customers in Q1 2011 worldwide.[123] 1.7 million smartphones using a Microsoft
Microsoft
mobile OS were sold in Q2 2011, for a 1.6% market share.[124] In Q3 2011, Microsoft's worldwide market share dropped slightly to 1.5%.[125] In Q4 2011 market share increased to 1.9%,[126] and it stayed at 1.9% for Q1 2012.[127] However it should be noted that such reports for Q2, Q3 and Q4 of year 2011 include both Windows
Windows
Phone and small part of Windows Mobile
Windows Mobile
marketshare under the same " Microsoft
Microsoft
mobile OS" banner, and do not make the distinction of separating the marketshare values of the two. According to Nielsen, Windows
Windows
Phone had a 1.7% market share in Q1 2012,[128] and then dropped back to 1.3% in Q2 2012.[129] Windows Phone 8
Windows Phone 8
(2012–2015)[edit] After the release of Windows
Windows
Phone 8, Gartner
Gartner
reported that Windows Phone's marketshare jumped to 3% in Q4 2012, a 124% increase over the same time period in 2011.[130] In mid-2012, IDC had suggested that Windows
Windows
Phone might surpass the faltering BlackBerry
BlackBerry
platform and potentially even Apple iOS, because of Nokia
Nokia
dominance in emerging markets like Asia, Latin America, and Africa, as the iPhone was considered too expensive for most of these regions and BlackBerry
BlackBerry
OS possibly going to feature a similar fate as Symbian.[131][132] IDC's projections were partially correct, as in Q1 2013 Windows
Windows
Phone shipments surpassed BlackBerry
BlackBerry
shipment volume for the first time.[133] IDC had to slash the Windows
Windows
Phone predictions once again, to 7 percent of total market in 2018, because of the slow growth.[134] As of the third quarter of 2013, Gartner
Gartner
reported that Windows
Windows
Phone holds a worldwide market share of 3.6%, up 123% from the same period in 2012 and outpacing Android's rate of growth.[135] According to Kantar's October 2013 report, Windows
Windows
Phone accounted for 10.2% of all smartphone sales in Europe and 4.8% of all sales in the United States.[136] Some analysts have attributed this spike in sales to both Windows Phone 8
Windows Phone 8
and Nokia's successful push to market low and mid-range Windows
Windows
Phones like the Lumia 520
Lumia 520
and Lumia 620
Lumia 620
to a younger audience.[137] Gartner
Gartner
reported that Windows
Windows
Phone market share finished 2013 at 3.2%, which while down from the third quarter of 2013 was still a 46.7% improvement from the same period in 2012.[138] IDC reported that Windows
Windows
Phone market share, having peaked in 2013 at 3.4%, had dropped to 2.5% by the second quarter of 2014.[139] In August 2017, the New York Police Department
New York Police Department
ordered Apple iPhone products to replace its deployment of 36,000 Lumia 830 and Lumia 640 XL Windows
Windows
Phone devices, partly citing Microsoft's end of support for Windows Phone 8.1
Windows Phone 8.1
and its minuscule market share.[140] Developer interest[edit] Microsoft's developer initiative programs and marketing have gained attention from application developers. As of Q3 2013, an average of 21% of mobile developers use the Windows
Windows
Phone platform, with another 35% stating they are interested in adopting it.[141] Some reports have indicated that developers may be less interested in developing for Windows
Windows
Phone because of lower ad revenue when compared to competing platforms.[142] The main criticism of Windows
Windows
Phone is still the lack of applications when compared to iOS and Android.[143][144][145][146] Developers are backing out of the platform and retiring apps because of the low market share.[147][148] See also[edit]
