The company said it had delayed the launch of the Galaxy Fold to "fully evaluate the feedback and run further internal tests".
In April, several early reviewers found the display on the Galaxy Fold broke after just a few days.
Samsung has not said when the £1,800 device will go on sale.
A new launch date will be announced in the "coming weeks".
In a statement, Samsung said it suspected the damage experienced by some of the reviewers was caused by "impact on the top and bottom exposed areas of the hinge".
