A Windows Phone Notification Center has been long-rumored and almost confirmed by Microsoft; despite some users claiming there is absolutely no need for one, we strongly disagree. We have recently seen leaks claiming that it will be part of the upcoming GDR3 update, but there’s no way of knowing, at the moment, whether we’re looking at GDR3, Windows Phone 8.1 (or a fake).
As you can see in the image above, we’re looking at a Live Tile called “Notifications” that will apparently, if this image is legit, show a number, corresponding to the number of notifications you are yet to see. There are no other details and the source of the image (apparently found lying on an SD Card) can’t really be verified. That being said, if this is the real deal, would you like such an implementation?
