Samsung Galaxy Z Fold 8’s durability gains questioned by rigorous tests

A durability test by JerryRigEverything highlights that despite design improvements, Samsung’s Galaxy Z Fold 8 remains vulnerable to scratches and dust, though its hinge demonstrates impressive resilience amid ongoing trade-offs.

Samsung’s Galaxy Z Fold 8 is being presented as a more practical step forward for foldables, but a durability test by Zack Nelson of JerryRigEverything suggests the real gains are narrower than the design language implies. The device’s new, more compact format looks closer to the shape of a future Apple foldable and to the next wave of book-style phones, yet its resilience still depends on the same familiar compromises: better sealing, careful hinge engineering and a display that remains less protected than a conventional handset.

Notebookcheck’s account of Nelson’s test says the Fold 8 carries an IP48 rating, which means it is protected against larger dust particles and full water immersion, but not against fine grit. That remains the key weakness for foldables, and Samsung has not eliminated it. SamMobile also reports that Samsung rates the hinge for 500,000 folds, a figure meant to reassure buyers that the mechanism should withstand heavy daily use, even if real-world wear still depends on how the phone is carried and used.

The display stack is where Samsung has made its most visible changes. According to SamMobile, the Fold 8 uses a new Flex Titanium layer, which Samsung says makes the panel far stiffer than older polymer films and helps reduce the crease. Notebookcheck says that improvement does not change one long-standing problem: the plastic surface above the AMOLED panel still scratches easily. The outlet also noted that Samsung can replace that outer layer at relatively low cost, which partly offsets the fragility but does not remove it.

Nelson’s bend test did, however, underline one of the device’s strengths. Even when he forced the Fold 8 against its natural folding direction, the phone did not crack or split. Notebookcheck says the 4.5mm aluminium chassis held together without visible structural failure, which is impressive for such a thin device. The camera hump, by contrast, is plastic and more exposed to scuffs, although the rings around the lenses are easier to replace if they become damaged. Tom’s Guide and TechRadar both argue that the Fold 8 is now one of the most polished large foldables on the market, but the durability evidence still points to a device that is tougher than earlier generations, not invulnerable.
