Samsung Galaxy X
Foldable display smartphone
There’s a limit to how big a phone can be, to enable its users to hold it and keep it in a pocket or handbag. However, if the device can be folded, it can suddenly potentially become a lot bigger when in ‘open’ mode. The Galaxy X purportedly bends in the middle and has been a concept since 2013, but whether or not the company is still actively pursuing the design at present is unknown.
