Windows Phone 10
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, 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.
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 asPCs, 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.[5] Some features may vary depending on hardware compatibility.
Windows 10 Mobile is designed for use on smartphones and small tablets under eight inches in screen size, 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.[7] The first Lumia smartphones powered by Windows 10 Mobile were released on November 20, 2015, while eligible Windows Phone devices are scheduled to begin receiving updates to Windows 10 Mobile in early 2016, pursuant to manufacturer and carrier support.
