Windows 10 Mobile is a mobile operating system developed by Microsoft. It is an iteration of the Windows Phone product line and a successor to Windows Phone 8.1,^[6] but is marketed as being an edition of Windows 10, Microsoft's operating system for personal computers, as part of Microsoft's plans to unify their platforms into one converged operating system.^[7]

Windows 10 Mobile aims to provide greater consistency with its counterpart for personal computers, including more extensive synchronization of content, a new universal application platform that allows one app to run on multiple Windows 10 devices such as PCs, mobile devices and Xbox, as well as the capability, on supported hardware, to connect devices to an external display and use a "PC-like" interface with mouse and keyboard input support. Microsoft has built tools for developers to easily port some iOS apps with minimal modifications. Windows Phone 8.1 smartphones are eligible for upgrade to Windows 10 Mobile, pursuant to manufacturer and carrier support.^[8] Some features may vary depending on hardware compatibility.^[9]

Windows 10 Mobile is designed for use on smartphones and phablets, running on ARM as well as IA-32 processor architectures. Windows 10 Mobile entered public beta for selected Lumia brand smartphones on February 12, 2015.^[10] The first Lumia smartphones powered by Windows 10 Mobile were released on November 20, 2015 while eligible Windows Phone devices began receiving updates to Windows 10 Mobile on March 17, 2016, pursuant to manufacturer and carrier support.

Development

Microsoft had already begun the process of unifying the Windows platform across device classes in 2012; Windows Phone 8 dropped the Windows CE-based architecture of its predecessor, Windows Phone 7,^[11] for a platform built upon the NT kernel that shared much of the same architecture with its PC counterpart Windows 8 including file system (NTFS), networking stack, security elements, graphics engine (DirectX), device driver framework and hardware abstraction layer.^[12][13] At Build 2014, Microsoft also unveiled the concept of "universal" Windows apps. With the addition of Windows Runtime support to these platforms, apps created for Windows 8.1 could now be ported to Windows Phone 8.1 and Xbox One while sharing a common codebase with their PC counterparts. User data and licenses for an app could also be shared between multiple platforms.^[14]

In July 2014, Microsoft's then-new CEO Satya Nadella explained that the company was planning to "streamline the next version of Windows from three operating systems into one single converged operating system for screens of all sizes," unifying Windows, Windows Phone, and Windows Embedded around a common architecture and a unified application ecosystem. However, Nadella stated that these internal changes would not have any effect on how the operating systems are marketed and sold.^[15][16]

On September 30, 2014, Microsoft unveiled Windows 10; Terry Myerson explained that Windows 10 would be Microsoft's "most comprehensive platform ever," promoting plans to provide a "unified" platform for desktop computers, laptops, tablets, smartphones, and all-in-one devices.^[17][18] Windows 10 on phones was publicly unveiled during the Windows 10: The Next Chapter press event on January 21, 2015; unlike previous Windows Phone versions, it would also expand the platform's focus to small, ARM-based tablets. Microsoft's previous attempt at an operating system for ARM-based tablets, Windows RT (which was based upon the PC version of Windows 8) was commercially unsuccessful.^[19]

During the 2015 Build keynote, Microsoft announced the middleware toolkit "Islandwood", later known as Windows Bridge for iOS, which provides a toolchain that can assist developers in porting objective-C software (primarily iOS projects) to build as Universal Windows Apps.^[20][21] An early build of Windows Bridge for iOS was released as open source software under the MIT License on August 6, 2015.^[21][22] Visual Studio 2015 can also convert Xcode projects into Visual Studio projects.^[21][23][24] Microsoft also announced plans for a toolkit codenamed "Centennial",^[25] which would allow desktop Windows software using Win32 APIs to be ported to Windows 10 Mobile.^[26]

At Build, Microsoft had also announced an Android runtime environment for Windows 10 Mobile known as "Astoria", which would allow Android apps to run in an emulated environment with minimal changes, and have access to Microsoft platform APIs such as Bing Maps and Xbox Live as nearly drop-in replacements for equivalent Google Mobile Services. Google Mobile Services and certain core APIs would not be available, and apps with "deep integration into background tasks" were said to poorly support the environment.^[27][28] On February 25, 2016, after having delayed it in November 2015,^[26][29] Microsoft announced that "Astoria" would be shelved. The company argued that it was redundant to the iOS toolkit (which assists in compiling apps natively, and does not use emulation) because of the platform's prominence in multi-platform mobile development, and encouraged use of products from Xamarin (which Microsoft had acquired the previous day) for multi-platform app development using C# programming language instead.^[25][30]

Naming

In accordance with Microsoft's branding strategy, this operating system will be branded primarily as an edition of Windows 10, rather than "Windows Phone 10". Microsoft had begun to phase out specific references to the Windows Phone brand in its advertising in mid-2014, but critics have still considered the operating system to be an iteration and continuation of Windows Phone due to its lineage and similar overall functionality. Microsoft referred to the OS as "Windows 10 for phones and small tablets" during its unveiling,^[31] leaked screenshots from a Technical Preview build identified the operating system as "Windows 10 Mobile"^{[32][33][34][35]} and the technical preview was officially called the "Windows 10 Technical Preview for phones".^[36] Internally, the Microsoft Edge user agent on Windows 10 Mobile still contains a reference to "Windows Phone 10".^[37]

On May 13, 2015, Microsoft officially confirmed the platform would be known as Windows 10 Mobile.^[6][38]

Features

A major aspect of Windows 10 Mobile is a focus on harmonizing user experiences and functionality between different classes of devices—specifically, devices running the PC-oriented version of Windows 10. Under the Universal Windows Platform concept, Windows Runtime apps for Windows 10 on PC can be ported to other platforms in the Windows 10 family with nearly the same codebase, but with adaptations for specific device classes. Windows 10 Mobile also shares user interface elements with its PC counterpart, such as the updated Action Center and settings menu.^{[14][19][31][32][39]} During its initial unveiling, Microsoft presented several examples of Windows apps that would have similar functionality and user interfaces between Windows 10 on desktops and mobile devices, including updated Photos and Maps apps, and new Microsoft Office apps.^[40][41][42] Although marketed as a converged platform, and as with Windows Phone 8, using a Windows NT-based kernel, Windows 10 Mobile still cannot run Win32 desktop applications, but is compatible with software designed for Windows Phone 8.^[43]

Notifications can be synced between devices; dismissing a notification on, for example, a laptop, will also dismiss it from a phone. Certain types of notifications now allow inline replies. The start screen now has the option to display wallpapers as a background of the screen behind translucent tiles, rather than within the tiles.^[44] The messaging app adds support for internet-based Skype messaging alongside SMS, similarly to iMessage, and can synchronize these conversations with other devices.^[33][45] The camera app has been updated to match the "Lumia Camera" app previously exclusive to Lumia products,^[45] and a new Photos app aggregates content from local storage and OneDrive, and can perform automatic enhancements to photos.^[45] The on-screen keyboard now contains a virtual pointing stick for manipulating the text editing cursor, a dedicated voice input button, and can be shifted towards the left or right of the screen to improve one-handed usability on larger devices.^[32][45][46]

Windows 10 Mobile supports "Continuum", a feature that allows supported devices to connect to an external display, and scale its user interface and apps into a "PC-like" desktop interface with support for mouse and keyboard input over USB or Bluetooth.^[47][48] Devices can connect directly to external displays wirelessly using Miracast,^[49] via USB Type-C, or via docking station accessories with USB ports, as well as HDMI and DisplayPort outputs.^[50]

A new iteration of the Office Mobile suite, Office for Windows 10, is also bundled. Based upon the Android and iOS versions of Office Mobile, they introduce a new user interface with a variation of the ribbon toolbar used by the desktop version, and a new mobile version of Outlook. Outlook utilizes the same rendering engine as the Windows desktop version of Microsoft Word.^[39][40][51] Microsoft Edge replaces Internet Explorer Mobile as the default web browser.^[52]

Release

Windows 10 Mobile's first-party launch devices—the Lumia 950, Lumia 950 XL, and Lumia 550—were released in November 2015.^[53][54] Monthly updates to OS software will be released to address bugs and security issues. These updates will be distributed to all Windows 10 Mobile devices and not require the intervention of a user's wireless carrier in order to authorize their distribution. Firmware upgrades will still require authorization by the user's carrier.^[55]

The Windows Insider program, adopted to provide a public beta for the PC version of Windows 10,^[56] is used to provide a public beta version of Windows 10 Mobile for selected devices.^[57] A build released on April 10, 2015 was to support most second and third generation Lumia products, but the Lumia 930, Lumia Icon, and Lumia 640 XL did not receive the update due to scaling bugs, and delivery was suspended as a whole due to backup and restore issues on some models.^[58][59] An update to the Windows Phone Recovery Tool resolved these concerns,^[60] and delivery of Windows 10 updates was restored to the 520 with build 10052, and to the 640 with build 10080.

Build number 10136 was released on June 16, 2015, with a "migration bug" that required that existing devices on build 10080 be reverted to Windows Phone 8.1 using the Recovery Tool before the installation of 10136 could proceed.^[61] This migration bug was fixed a week later with the release of build 10149.^[62] Mobile builds of the Redstone branch till 14322 were halted for the device Lumia 635 (1 GB RAM) due to bugs.^[4]

Upgrade release

Some Windows Phone 8.1 smartphones can be upgraded to Windows 10, pursuant to hardware compatibility, manufacturer support, and carrier support. Not all phones can receive the update nor support all of its features.^[8][57] Microsoft originally stated that stable upgrades for Windows Phone 8.1 devices would be released in December 2015; however, the release was ultimately delayed to March 17, 2016.^[63][64] Among first-party devices, only the Lumia 430, 435, 532, 535, 540, 635 (1 GB RAM), 640, 640 XL, 735, 830, 930 and 1520 are supported. The only third-party devices supported are the BLU Products Win HD w510u and Win HD LTE x150q, and the MCJ Madosma Q501. Windows 10 Mobile is not supported by any HTC devices (HTC Windows Phone 8X, HTC One (M8) for Windows). While Microsoft stated that the Nokia Lumia Icon may be upgraded at a later date, the company stated that there will not be a second wave of officially-supported devices. Microsoft also removed statements which promoted the BLU Win JR LTE as being compatible with Windows 10.^[65][66][67]

Microsoft originally stated that all Lumia smartphones running Windows Phone 8 and 8.1 would receive updates to 10, but Microsoft later reiterated that only devices with the "Lumia Denim" firmware revision and at least 8 GB of internal storage would receive the upgrade.^[46][54] In February 2015, Joe Belfiore stated that Microsoft was working on support for devices with 512 MB of RAM, (such as the popular Nokia Lumia 520),^[57] but these plans have since been dropped.^[68] Upon the official upgrade release, some Lumia models, particularly the Lumia 1020 and 1320, were excluded despite meeting the previously announced criteria. Microsoft cited poor user feedback on the performance of preview builds on these models as reasoning.^[69]

Devices

As with Windows Phone, Windows 10 Mobile supports ARM system-on-chips from Qualcomm's Snapdragon line, adding support for the 200, 208, 210, 615, 808, and 810. The operating system will also introduce support for IA-32 system-on-chips from Intel and AMD, including Intel's Atom x3 and Cherry Trail Atom x5 and x7, and AMD's Carrizo. Although some of these supported chips are 64-bit, Windows 10 Mobile only supports 32-bit operation.^[70]

Minimum specifications for Windows 10 Mobile devices are similar to those of Windows Phone 8, with a minimum screen resolution of 800×480 (854×480 if software buttons are in use) and 512 MB of RAM. Owing to hardware advancements and the operating system's support for tablets, screen resolutions can now reach as high as QSXGA resolution (2560×2048) and further, as opposed to the 1080p cap of Windows Phone 8. The minimum amount of RAM required is dictated by the screen's resolution; screens with a resolution higher than 960×540 require 1 GB of RAM, screens of 1440×900 and higher require 2 GB, 2048×1152 and higher require 3 GB, and 2560×2048 and higher require 4 GB.

Microsoft unveiled flagship Microsoft Lumia smartphones during a media event on October 6, 2015, including Lumia 950, Lumia 950 XL, and the low-end Lumia 550.^[53]
