Microsoft's Lumia 950, the flagship Windows phone due for release later this year, has been revealed in a series of leaked photos. WPXAP, who leaked the first photos, showed the phone inside a protective black casing and plugged in with what seems to be a USB-C cable. A second leak on Weibo, via WindowsCentral, shows the phone in use. The leaks reveal that the phone will eschew physical buttons on the front in favour of on-screen buttons.

According to previously-leaked specs, both phones will support iris scanning, a key feature of Windows 10. The 5.2-inch Lumia 950 comes with a slightly slower processor than the 5.7-inch Lumia 950 XL, with the bigger phone also including Surface pen support.

Both devices are reported to come with a 20-megapixel rear camera and 5-megapixel front camera. While it was previously reported that the phones would be released as the 940, WindowsCentral says that Microsoft will skip this designation and jump straight to 950.

The previous specs leak also suggested that the phone will cost more than the iPhone 6, which starts at $649 without a contract. This is despite the fact that the phones are reportedly made out of plastic, with phones in similar price ranges made out of more premium materials like aluminum.

A report on Monday said that alongside the two phones, Microsoft will also release a Lumia 840 this year. This report also suggested that the Lumia flagship would, in fact, be called the 940. Rumors also suggest that Microsoft is planning to announce its phone release plans at the September 4th IFA 2015 event in Berlin.
