Just as we wrapped up our Samsung Galaxy Z Fold4 review, JerryRig Everythingthe durability test of the same device decreases. The construction and structural integrity of the Z Fold4 remain unchanged from the Z Fold3, with the exception of the upgrade from Gorilla Glass Victus to Victus Plus on the external display. The Z Fold4 is still IPX8 water resistant and the internal display is still protected by a plastic cover.
Gorilla Glass Victus Plus had no additional scratch properties, as the external display still scratched at a level 6 (on Moh’s hardness scale) with deeper grooves at a level 7. Meanwhile, the internal display is still quite soft from Samsung it needs to warn you not to press too hard as nails can leave permanent marks. A level 2 pick will leave permanent marks here.
After leaving permanent burn marks in both displays using a lighter and scratching all the various materials of the phone with a razor blade, the Z Fold4 was dusted with gravel on both sides of the hinge. After opening and closing the device several times, the hinge survived the attempt to breach the gravel.
Finally came the bend test, attempting to bend the device while it was closed proved difficult. When trying to fold the Z Fold4’s screen past its open position, it didn’t move much. The Z Fold4 surpassed the JerryRig Everything durability test.
