Microsoft received a patent for a foldable smartphone

The other day a patent application for a folding phone filed last year was approved, which means that Microsoft has become even closer to creating the first folding device.
According to the documentation, the smartphone can be easily converted into a tablet and vice versa. Previously it was believed that the gadget will have two screens, but the drawing shows that there will be one flexible panel. Thanks to the folding mechanism, the folded device easily turns into a smartphone.

It is assumed that smart phones of this type will be purchased by businessmen, heads of departments and other customers who will need a large display.
The approximate release date of the device, as well as its characteristics are not known.
