Check out this short video of the future concept of Samsung smartphone. Although there are many video showing such concepts, this one is shown by Samsung president Young Sohn (according to YouTube source), which makes it more authentic.
Here is the proof of concept of the smartphone. It is foldable and uses advance technology in terms of display.
What do you think of this concept? I seen people commented that it does not have a rear camera. In my opinion, it might be an add-on for such phones.
