Microsoft Corporation (NASDAQ:MSFT) seems to be building a foldable smartphone.

A new patent, discovered by MSPoweruser, reveals that the Redmond-based tech giant is working on a foldable device with a flexible hinge and display. It appears to be a phone-to-tablet mobile device.

In the patent, the company described “a device that is flexible supported by a flexible hinge structure that secures the plurality of housings to each other, permits the plurality of housings to rotate about an axis in relation to each other, and supports a continuous viewing area of the display device that extends across the plurality of housings and the flexible hinge structure,” according to the report.

The tech giant is rumored to be developing a smartphone under its Surface brand. So, it’s safe to assume that the company might introduce a foldable Surface Phone.

Rumors suggest that the Microsoft Surface Phone would be an iPhone killer. However, the software maker hasn’t disclose any details about the purported Surface Phone.

The Surface Phone is said to come in three distinct variants: consumer edition, business edition, and enthusiast edition. Rumors suggest that all variants will feature a 5.7-inch display.

The phone is expected to come packed with Qualcomm’s brand-new Snapdragon 835 processor. The Snapdragon 835 is a 10nm processor that is powerful as well as energy efficient – it uses 40% less power than the old Snapdragon 820. The Surface Phone might feature a 20 megapixel rear camera with a Carl Zeiss lens.

The Surface Phone is rumored to support Win32 apps. The availability of Windows programs would give the phone an edge over iPhone and Android devices, according to the IT experts.

According to the rumors mill, Microsoft would unveil the Surface Phone in the second half of this year.
