Samsung debuted its most extensive new lineup of smartphones, taking on Apple Inc.'s amid a slowing market.
Samsung is postponing its China launch event for its foldable smartphone on the nearly $ 2,000 device.
Samsung's Galaxy Fold, unveiled in full in February, is slated to go on sale on April 26 in select markets including the U.S.
CNBC has asked Samsung to clarify whether or not the postponement of the China event will affect it.
The screen on Samsung's device can fold in half and open again to give users a large display. However, journalists review the product over the past few weeks. Some of the reviewers removed a protective film which covered the screen, which appeared to be some problems with the display. But CNBC's Todd Haselton did not remove that film during his review and his screen ended up flickering and turning on and at a rapid pace.
In a statement following the screens of the damaged screens, Samsung advised not to remove the protective film and said it was looking into the issue.
"We will thoroughly inspect these units in person to determine the cause of the matter," the company said.
