After reviewers reported problems with the Galaxy Fold's screen last week, Samsung announced on Monday that it would delay the Fold's scheduled sale date. 

"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. There was also an instance where substances found inside the device affected the display performance," Samsung said in a statement. "To fully evaluate this feedback and run further internal tests, we have decided to delay the release of the Galaxy Fold."
