A new durability test suggests the Samsung Galaxy Z TriFold may be the most fragile modern Samsung foldable yet. In a hands-on stress test from popular durability YouTuber JerryRigEverything, the ultra-thin tri-fold design shows multiple weak points—ultimately becoming the first Samsung foldable on that channel to fail the infamous bend test.
The biggest issue appears to be how thin the Galaxy Z TriFold is. With a thinnest point of about 0.15 inches, the device prioritizes sleekness over structural strength. Even before the formal bend test begins, the phone shows signs of trouble during folding. When the right side is folded with the rear camera first—something Samsung reportedly warns users not to do—the device begins to vibrate, hinting at tight tolerances and potential hinge sensitivity.
Like most foldables, the large inner display uses a plastic-based surface, which is known to scratch more easily than glass. What stands out here is that the outer back panels also scratch readily because they’re made of fiberglass, a material that behaves more like plastic than premium glass or metal in scratch tests. For buyers who expect a rugged, everyday-carry flagship, that combination may raise concerns about long-term wear.
Dust and grit are another red flag. In the test, introducing heavy dirt causes the hinges to sound and feel “crunchy,” reinforcing the idea that hinge protection and debris resistance may not be as forgiving as users hope—especially compared to traditional foldables with more mature hinge designs.
The breaking point arrives during the bend test in the opposite folding direction. With two hinges and an ultra-thin chassis, the Galaxy Z TriFold appears easier to deform under intentional pressure, and it eventually fails. The test suggests that the tri-fold structure may have lower overall rigidity than Samsung’s other foldables, making it more vulnerable if it’s twisted in a bag, pressed in a pocket, or handled roughly.
After the bend test, the teardown reveals more design concerns—most notably the phone’s three-battery layout. During removal, pulling on the battery pull tabs reportedly causes the batteries to bend, which can be risky. Battery bending is widely viewed as a potential safety issue because it can increase the chance of damage to the cells.
The takeaway from the test is simple: the Samsung Galaxy Z TriFold may demand careful handling. The tester specifically warns against sitting on the device while it’s unfolded, and the overall results paint a picture of a futuristic form factor that may still be in its early, less durable stage compared to more established foldable designs.
For shoppers considering a tri-fold phone, this kind of durability report is worth factoring into the decision—especially if your daily routine includes dust, travel, tight pockets, or situations where your phone might get squeezed or flexed.
