Following the launch of Lumia 550, Lumia 950, and Lumia 950 XL smartphones, Microsoft is gearing up for its launch of the next flagship smartphone: Lumia 850. A new image has been appearing on the internet showing the handset's protective cases which tipped the design of the device.

According to the images shared by Gizmochina, it shows that the device has the power button and the volume button on the right panel, while the rear camera is placed at the top centre with the LED flashlight placed above it. The image shows the blue colour variant of the Lumia 850, and as the protective case is covered on the back panel, nothing else can be said on the device as of the moment.

It is speculated that the Lumia 850 will run on Windows 10 and will have a metal frame. The device will sport a 5-inch 768x1280 pixel resolution display and will be powered by Qualcomm Snapdragon 410 SoC paired with a 1GB RAM. A 10-MP rear camera with Zeiss lens, 16GB built-in memory and a 2,650 mAh battery are incorporated in the device, notes NDTV.

Earlier reports in July indicated that Microsoft is testing Lumia 850 along with Lumia 650, and it is worth noting that images of Lumia 650 was leaked over the internet last month.

Last week, Chris Capossela, Microsoft Chief Marketing Officer, hinted in an interview that the company is working on a high-end smartphone. It is rumoured that the new high-end smartphone may be the Surface Phone. Moreover, he conceded that the company is planning to launch a "breakthrough" phone and will be the "spiritual equivalent" of the company's Surface tablet line. He went on to say that Microsoft requires more time to build the device and requested the interested users to maintain patience.

The company is currently offering the Display Dock for free for the buyers of Lumia 950 and Lumia 950 XL smartphones in Australia.
