Photos of what appears to be the canceled Lumia "Northstar" Windows phone have leaked, revealing what could have been for Microsoft's successor to the Lumia 950.

As we all know, Microsoft decided to retrench its mobile efforts at some point during the last two years. Because of this, several of Microsoft's planned phones were canceled internally, including the Lumia 750 and Lumia 850. Today, photos of what appears to be the successor to the Lumia 950 have leaked, revealing what Microsoft may have had planned for a "Lumia 960".

Windows Central understands that the codename for this device is Northstar, and was used internally as an engineering prototype for building Windows 10 Mobile. It features a metal design, and looks similar to a 950 on the front, with a few small differences such as front facing speakers. The leaked photos and info say the prototype included a Snapdragon 820 and a QHD screen.

While not officially referred to as the Lumia 960, it's not hard to imagine this is the kind of name Microsoft would have went with had they not decided to retrench their mobile efforts and cancel its Lumia line of devices. Now, we understand Microsoft is working on yet another new device, that'll likely be released under the Surface branding instead of Lumia.

We'll have more to share regarding the future of Windows phone soon, but in the meantime, what are your thoughts on the canceled Lumia 960? Let us know below.
