News of a Microsoft foldable known as ‘Andromeda' have been floating around the web, but it appears Apple is working on a similar device. A recently published patent decscribes a “folding device with a flexible display,” and was applied for in September 2016. Of course, this doesnt nessecarily mean that Apple will release such a device, but it's easily possible. Samsung has also expressed interest in such a device, and Apple has a history of perfecting existiting designs. Apple's push for a flexible display rather than a hinge-based one is interesting, as is its vision to achieve it. The patent describes use of nanotubles and optically clear adhesive to protect the screen, as well as a shape memory alloy to allow folding of the frame. Despite this, it's unclear if consumers will be interested in such a device. It could be useful for reading and multitasking, but will come at the price of extra thickness.

The foldable iPhone patent suggests a device that can be manipulated without hinges and suggests Micro-LED for its display. At this point, it's unclear if the concept will make it to market.
