The Galaxy Z Fold4 from Samsung, the company's newest large foldable, withstood JerryRigEverything's "durability test" at the end of last month, though it wasn't quite in perfect condition.
Now it's the turn of its younger sibling, the Galaxy Z Flip4, to go through the same arduous evaluations. Let's see if it turns out that the smaller device is more brittle or not.
Since the Flip4's exterior screen is made of glass, as one might imagine, it scratches at level 6 on the Mohs scale, with deeper ridges appearing at level 7. In contrast, the inner display, or rather the screen protector placed on top of it, only develops level 2 scratches, whereas level 3 scratches result in deeper grooves. This implies that the surface could actually be harmed by fingernails.
Aluminum makes up the phone's sides, while metal is used for the keys and the SIM card slot. The phone is exposed to a lot of dirt, much like with the Fold4, to test the hinge, and everything works out just fine. Since it is plastic after all, the interior screen protector melts when exposed to an open flame.
Finally, the Flip4 bends backwards a lot, and not without strange popping noises coming out of it, but remains functional without any issue. However, after being subjected to all that abuse, it doesn't fully close anymore. The purpose of this test was to figure out how durable a foldable device is these days, and hopefully if you were wondering about that it provides a useful answer.
