Windows Phone 8

Windows Phone 8 is the second generation of the Windows Phonemobile operating system from Microsoft, released on October 29, 2012. It runs on the Windows NT kernel and is the successor to Windows Phone 7. It was the first Windows platform for mobile devices to be closely related to, and match the version number, of a desktop counterpart, in this case Windows 8.
Like its predecessor, it features a flat user interface based on the Metro design language. Windows Phone 8 replaced the Windows CEkernel used in Windows Phone 7.x with the Windows NT kernel found in Windows 8. As a consequence of this, all Windows Phone 7.x devices cannot run or update to Windows Phone 8, and new applications compiled specifically for Windows Phone 8 are not made available for Windows Phone 7.x devices. Windows Phone 8 devices were manufactured by Nokia, HTC, Samsung and Huawei.
Windows Phone 8 was succeeded by Windows Phone 8.1, which was unveiled on April 2, 2014. Support for Windows Phone 8 ended in January 2016.
