SEOUL— Samsung Electronics Co. is delaying the rollout of its Galaxy Fold smartphone until at least next month after some tech reviewers said their test devices had malfunctioned.
The Galaxy Fold phone—priced at nearly $2,000 and the industry’s first mainstream foldable-screen device—was slated to hit shelves in the U.S. on Friday. But Samsung, citing the reported problems with the phone, said Monday it plans to announce a new release date in the coming weeks.
“Initial findings from the inspection of reported issues on the display showed that they could be associated with impact on the top and bottom exposed areas of the hinge,” the company said. “There was also an instance where substances found inside the device affected the display performance.”

Samsung, the world’s largest phone maker, has high hopes for the Galaxy Fold handset, which folds in half like a book. It boasts a tablet-sized screen measuring 7.3 inches diagonally. When closed, it sports a second, smaller outer display that can perform most tasks.
