GoKawiilJerryRigEverything teardown finds iPhone Duo's folding screen scratches easily
YouTuber JerryRigEverything put Apple's iPhone Duo through a battery of durability tests, scratching the inner display with keys, coins and chainmail, and pouring in sand to test its IP68 rating. He also stripped off the nanotexture coating against Apple's warnings, noting the screen looked better glossy but scratches became more visible once stripped.
