New photos of Lumia 950 and Lumia 950 XL prototypes show triple LED flash on both models70
The images also confirm that there will be a dual SIM version of both the Lumia 950 and Lumia 950 XL, and we also get a better look at the low-infrared diode used by the iris scanner on both models. With the scanner, Lumia 950 and Lumia 950 XL users will be able to unlock their phones simply by looking at them.
We expect to see both the Lumia 950 and Lumia 950 XL unveiled during Microsoft's media event, which will be held this coming Tuesday in New York City. Besides the two high-end phones, we could also see the unwrapping of the Microsoft Surface Pro 4, and the Microsoft Band 2.
The Lumia 950 and Lumia 950 XL aren't expected to be actually launched until sometime in November.
