Samsung plans to sell a Galaxy Note with a foldable screen in 2018

Head of Samsung mobile says 'holy grail of smartphones' should be available next year, although company still has several hurdles to overcome

Samsung is aiming to launch a Note smartphone with a screen that folds next year, which would likely be the first available to feature such an innovation.

Koh Dong-jin, president of Samsung's mobile business, said the company is setting its eyes on 2018 to release a smartphone using its bendable OLED screen technology, but he said there are several hurdles it has to overcome, leaving room to push back the release if those problems are not solved.
