This is the long-awaited Surface phone, which has been rumored for many years.
But apart from its innovative design, the phone runs on Google’s Android operating system instead of its own Windows.
The Surface Duo features two 5.6-inch displays that can be expanded to a large 8.3-inch screen with a thickness of only 4.8 mm.
Microsoft said that dual-screen devices allow people to do more work on the go.
They found that its actual size is much smaller than the size on the photo.
It looks and feels like a miniature tablet and a smartphone.
