Microsoft patent application suggests a true foldable phone is coming with a thin form factor, more،
The second (and final) Surface Duo features a pair of 5.8-inch displays that can be used as an external cover display on the front or back of the phone. When the device is fully opened, users have a tablet-sized 8.3-inch canvas to work with. Let's give the Surface Duo a moment of silence. That's enough. Now, what's next for Microsoft in terms of smartphones? A patent application filed by Microsoft could shed light on the form factor the company envisions for its next connected phone.

The SurfaceDuo 2
Microsoft is looking for the spine cover plate to kill two birds with one stone. The phone will be more durable and therefore less prone to damage from an accidental hit. And it will also make it harder to see a crease. By moving closer to the hinge mechanism when the device is closed, the back plate makes the phone thinner and easier to hold.

In the patent application, Microsoft writes: “By retracting the back cover plate toward the center back when the first screen support frame and the second screen support frame rotate in a face-to-face orientation, the width of the folded computer support The device is reduced, thus allowing easier and more comfortable handling of the device, for example with one hand.
The Surface Duo had its supporters even though it was truly a niche product. When Surface chief Panos Panay left Microsoft last September, it may have changed Microsoft's future plans for another Surface phone. However, this patent application has been published and we will see if it leads to a real foldable phone from Microsoft.
