Samsung Display’s principal engineer has revealed that foldable phones may not be commercialized until 2019 as there are still technical challenges to be addressed. This news comes shortly after a report surfaced online claiming the firm will take the wraps off the handsets later this year.

“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 Kim Tae-woong, Samsung Display’s principal engineer. It’s believed that as demand for bezel-free devices slows, foldable displays will be introduced.

Bad news for folk hoping to pick up the long-rumored Galaxy X this year, then.
