Now, a clearer mockup of that photo has been posted by the site WinSource . We say ‘mockup’ because it is technically not a real photo of the OS in action. Rather, it’s a re-creation of that photo and what it conveys. Having said that, what is shown in truly based off of Windows Phone 8.1.

Back in December, a really poor (but accurate) photo of the Windows Phone 8.1 notification settings screen was revealed on Twitter by a Salman M. At the time, we confirmed internally that it was real, though possible older.

Specifically, we are looking at just the Settings page for Notifications, not the notifications themselves (or the new notification center). In that sense, this really isn’t too newsworthy. But since we know many in our audience are yearning for something real, here you go. It’s about as close as we can get right now.

What is shown in the image are configurable ‘quick settings’ for the Notification Center, allowing users to add certain system functions for quick access. There are also more advanced options to allow users to fine tune how and which notifications come through on their Windows Phone.

We should add a caveat that this is an older design. Sources familiar with Windows Phone 8.1 have told us that since this design they have added “…fine grained control over the sounds of each type of notification.”, so don’t take this to be the final way it will look. But it is a close approximation.

Microsoft is expected to discuss Windows Phone 8.1 in April during their Build conference. Windows Phone Central will be there to cover it live.

Correction: An earlier version of this article cited an incorrect originator of the mockup. It has now been fixed.
