Samsung won’t launch its first foldable smartphone — dubbed the Galaxy X — until 2019 as there are still technical challenges to be addressed, reveals The Korea Herald. It’s believed that the handset will hit the shelves when demand for bezel-free displays (like the one on board the Galaxy S8) eventually slows.

“Because the bezel-free display currently sells well, we still have enough time to develop foldable display. The technology is expected to be mature around 2019,” said Samsung Display’s principal engineer Kim Tae-woong in a statement made to the publication at the Display TechSalon conference in Seoul, South Korea on Tuesday.

A single-sided foldable device should arrive first

As there are still technical limitations to overcome, Kim notes that it’s likely a single-sided foldable device will arrive first, with a double-sided unit — where the screen unfolds on both sides to create a larger, tablet-sized panel — debuting at a later date. Unfortunately, an exact timeframe was not provided.
