Galaxy Z TriFold Fails Reverse-Bend Durability Tests, Exposing Design Weaknesses

Independent testing points to a thin spine plus exposed hinge gaps as the weak links.

Overview

  • JerryRigEverything’s video shows the tri-fold phone breaking when bent opposite its intended direction, with torn pixels, dark screen sections and a visibly damaged hinge area.
  • Multiple outlets report this is the first time a Samsung phone has failed the channel’s bend test, leaving the device effectively unusable after the stress.
  • Dust testing drew pocket sand into the mechanism, producing grinding noises as the IP48-rated device’s hinge gaps and internal magnets allowed debris to intrude.
  • The central frame measures roughly 3.9 mm at its thinnest, and reports note the hinges held while the ultra-thin aluminum spine buckled along antenna lines.
  • Scratch and heat checks reinforce fragility: the inner display marks at Mohs level 2 and blackens after about 10 seconds of flame, versus level 6 and around 17 seconds for the outer panel, even as Samsung advertises up to 200,000 intended folds.
