Microsoft launched their flagship Windows phones for 2015, the Lumia 950 and the Lumia 950XL a few months back alongside the budget Lumia 550. However the Redmond giant hasn't revealed any details regarding the successors to their aging Lumia 830 and Lumia 730.
A new report by @onleaks however suggest that the Redmond giant is indeed working on the two mid-range devices. The tipster has also leaked some details regarding one of those i.e. Microsoft Lumia 850. Interestingly the Lumia 850 is seen sporting a metal frame in the set of images revealed by the @onleaks.
The tipster further adds that the metal clad Microsoft Lumia 850 measures at 155.9x77.23x6.92mm which makes it the slimmest Lumia phone till date. Surprisingly the leaked dimensions of the device is larger than that of the Lumia 950XL which measures at 151.9x78.4x8.1mm. Hence it would be safe to assume that the Lumia 850 would sport a display of around 5.7 inch - 6 inch if the leaked dimensions are assumed to be accurate.
The leaked renders according to the tipster are industrial sketches received from trusted sources. Thus it isn't safe to assume that this will be the final design of the alleged device - often than not the companies make minor changes to the design just before they go for prototyping. However this does give us a look into what the Lumia 850 will look like.
Nevertheless one thing is for sure - the Lumia 850 isn't coming anytime soon. Expect it to launch early next year with Windows 10 on board. More details about the alleged device will surface with each passing days.
