Windows Phone 8 also allows devices with larger screens (the four confirmed sizes are 'WVGA 800×480 15:9','WXGA 1280×768 15:9','720p 1280×720 16:9','1080p 1920x1080 16:9' resolutions) and multi-core processors, NFC (that can primarily be used to share content and perform payments), backwards compatibility with Windows Phone 7 apps, improved support for removable storage (that now functions more similarly to how such storage is handled on Windows and Android), a redesigned home screen incorporating resizable tiles across the entire screen, a new Wallet hub (to integrate NFC payments, coupon websites such as Groupon, and loyalty cards), and 'first-class' integration of VoIP applications into the core functions of the OS. Windows Phone 8 replaces its previously Windows CE-based architecture with one based on the Windows NT kernel, and shares many components with Windows 8, allowing developers to easily port applications between the two platforms.

On June 20, 2012, Microsoft unveiled Windows Phone 8 (codenamed Apollo), a third generation of the Windows Phone operating system for release later in 2012.
