Windows Phone 8.1 is expected to go official in April during the annual BUILD conference. Meanwhile, thanks to Microsoft's WP8.1 SDK, various screenshots and videos have gave us a taste of the upcoming update.
WP 8.1 is expected to bring the long awaited Action Center, Cortana voice assistant, Swype keyboard, better multi-tasking, burst shots for the camera, Internet Explorer 11 with password manager, minor UI enhancements, etc.

Today, after various leaked screenshots we finally get to see the Action Center in action in a live video. There aren't many surprises here, but then again there's no need to reinvent the wheel.
