It's not a dream anymore, with new technologies emerging then and now, Foldable Smartphones are a thing now.

What we call a foldable smartphone?:

A foldable smartphone is a form factor of a smartphone, which allows access to a larger, tablet-like display when needed by unfolding the device, whilst maintaining a similar footprint and functionality to a standard smartphone when folded (typically along a vertical axis). The screen may either wrap around to the back of the device when folded (as with the Royale Flexpai and Huawei Mate X), or use a booklet-like design where the larger, folded screen is located on the interior, and a screen on its "Cover" allows the user to interact with the device without opening it (such as the Samsung launched its first foldable smartphone Galaxy Fold).

The time ever when the foldable screen came into the picture was back on 2008, when Nokia presented animated concepts of a flexible device it dubbed "Morph", which had a tri-fold design that could be bent into various forms, such as a large unfolded device, a feature phone-sized unit, and a smart wristband.

After that several other companies came with this foldable screen concept along with adding features like dual touchscreen, a secondary display and much more. But these were all just mere rip off to the original concept, rather trying to gimmick the real deal.


Some well reputed mobile manufacturer like Huawei , Samsung, Motorola, Oppo are constantly putting their research and development efforts in foldable phone technology.

In January 2019, Xiaomi CEO Lin Bin published a video on Sina Weibo, featuring him demonstrating a prototype smartphone with two flaps capable of being folded inward. Samsung officially unveiled the Galaxy Fold during its media event at Mobile World Congress in February 2019. Alongside the Galaxy Fold, the convention also saw other foldable phones being unveiled or teased, such as the Huawei Mate X, and TCL presenting various prototype concepts featuring its "DragonHinge" technology (including a bracelet-styled device).

Well, I could certainly say that the future with the foldable smartphone is pretty bright, but for a while now, as it happened with the notch display, it's going to stick with the premium/flagship devices.
