Samsung used a new blog post to single out three foldable milestones—UTG, IPX8 water resistance and the Flex Hinge—as the advances that helped legitimize the category.
2020 brought UTG to the Galaxy Z Flip, 2021 added IPX8 on the Z Fold 3 and Z Flip 3, and 2023 introduced the Flex Hinge on the Z Fold 5 and Z Flip 5.
The retrospective comes as Samsung prepares its next foldable launch, with teasers pointing to a new model expected to feature a wider aspect ratio.
That framing positions 2026 as Samsung's next test for foldables, after seven years of annual updates since the first commercial Galaxy Z Fold debuted in 2019.
