Microsoft is rumored to be working on a flagship smartphone. The details of the mysterious smartphone have surfaced on GFXBench benchmarking site.

Currently, the most powerful smartphone running on Windows 10 Mobile is the HP Elite X3 that is fueled by Snapdragon 820 SoC. Rumors also suggest that the Redmond giant is prepping up a flagship smartphone.

Microsoft is long rumored to be working on a Surface Phone. Speculations now suggest that Lumia lineup will continue to co-exist with Surface phone.

Meanwhile, a smartphone with model number RM-1162 has been spotted on GFXBench database. The listing shows that the alleged Lumia 960 will be arriving with 5.5-inch display that will carry support for Quad HD resolution.

The RM-1162 is powered by Snapdragon 820 chipset. The listing shows that the smartphone features 1.5 GB of RAM. However, various tech sites have reported that the mysterious smartphone would be arriving with 4 GB of RAM.

It is expected to arrive with 32 GB of storage. A prototype model of the smartphone was found featuring 16 GB of storage. Although the benchmarking site has mentioned the camera of the device as 7-megapixel, it seems to be incorrect.

The reason behind it is that since the camera is expected to support 4K resolution video recording, it may feature a camera of either 13-megapixel or higher. Previous rumors have suggested that it may either come with a 23 or 20-megapixel camera. The front-facing camera is of 8-megapixel.

The GFXBench listing of the alleged smartphone has not revealed any information on the remaining specifications. However, the NPU report has revealed that it will be coming with full-metal body, Windows 10 Mobile Redstone 1 and iris scanner. Rumors suggest that it will release in second or third quarter of 2016.
