Various leaks have emerged over the past weeks and months about Microsoft’s new Lumia 950 and Lumia 550 phones, but those released today by leaker-in-chief Evan Blass give the clearest view yet of the as-yet-unannounced devices.

Microsoft may announce the phones at a press event scheduled for October 6th, where it is expected to officially lift the curtain on its Windows 10 Mobile OS.

The Lumia 950 is said to be a premium-level phone, powered by a Snapdragon 808 64-bit Hexa core processor, with 3GB of RAM. On the back of the phone is a 20-megapixel camera, with a 5-megapixel camera on the front. The display is 5.2 inches, at 1440 x 2560 pixels. The 950 is also said to have a USB-C port, an infrared iris scanner, and wireless charging.

The 950’s larger brother, the Lumia 950 XL, may also debut on October 6th. The XL has many of the same specs as the 950, but its screen is 5.7 inches and it’s powered by a Qualcomm Snapdragon 810 chip.

The Lumia 550 is a budget Windows 10 phone that’s said to sport a 4.7-inch screen and carry a Qualcomm Snapdragon 210 chip. It’ll reportedly come in black, white, red, and blue. The phone may be just one of a set of entry-level Microsoft phones announced during the fourth quarter, reports have said.

We’ll have complete coverage as these phones are announced, as well as hands-ons and full reviews.
