Samsung’s Galaxy Z Flip brags at least one structural development that makes its display superior to the Galaxy Fold from the previous year. It uses a novel ultra-thin glass (UTG) screen in place of a plastic display. This was believed to make the Galaxy Z Flip’s display more tough to scratches matched to the Galaxy Fold’s plastic screen. Nevertheless, a durability test of the phone proposes otherwise.
Renowned YouTuber and destroyer of phones Zack Nelson lately performed his well-known JerryRigEverything durability test on the Galaxy Z Flip. While placing the new clamshell foldable in its paces on the Mohs scale of hardness, Nelson hurriedly realized that the display of the phone scratches as effortlessly as that of its predecessor.
The display begins scratching at level two on the Mohs scale (equivalent to gypsum). The YouTuber notices that if this were manufactured from real glass, it would only display signs of scratching at level five or six, similar to most other phones that have glass displays.
Actually, deeper grooves begin emerging on the Z Flip’s display at level three. At level four, the pick succeeds to cut open the surface of the display. Nelson was also able to graze the screen with his fingernail. And he showed that the screen is also physically affected by temperature in a way only plastic would, not glass.
Samsung Galaxy Z Flip: Good enough, but isn’t this a dull use of foldable tech?
Nelson tells that the Galaxy Z Flip’s display does not have the structural benefits and scratch resistance that come with the use of glass. He suggested that the phone’s display is perhaps made of some type of plastic polymer with specks of glass inside.
Noticeably, this is not a good look for Samsung. It would be a huge deal if the company fibbed about the use of ultra-thin glass. Did it though?
“Samsung’s first-of-its-kind UTG technology is unlike other Galaxy flagship devices. Although the display does bend, it should be used with care,” Samsung wrote in an email to The Verge. “Also, Galaxy Z Flip has a shielding layer on top of the UTG like Galaxy Fold.”
Supporting Samsung’s claims, Display Supply Chain Consultants initiator Ross Young also tweeted about the use of plastic layers on the display.
Young also says that the plastic layer at the top of the ultra-thin glass is for break protection and safety if the glass breaks. This way, the glass shouldn’t cut your finger if it’s physically damaged.
Looks like even if there’s ultra-thin glass on the Z Flip, it has the same plastic coating as the Galaxy Fold. This shows that the display can easily suffer scratches from pens, keys and even your own fingernails. Though, the plastic layer could guard the actual glass display from getting permanently scratched.
What about the general durability of the phone?
Based on @ZacksJerryRig's testing, @SamsungMobile owes the world a hell of a lot of explaining about claiming the Z Flip's display cover material is "glass." He literally pokes holes in it with his testing tool. https://t.co/gesLGpLlib

In spite of how easily the display on the Galaxy Z Flip scratches, Nelson notices that it’s the sturdiest foldable phone he has experienced. The Z Flip does fairly well in its bend test, keeping its display working even after a crack in the frame. Amazingly, the ultra-thin glass does not split when the phone is bent outwards.
Nelson also applauses Samsung’s new hinge design as it avoids dust and gravel from getting trapped inside. It also doesn’t cause the screen to lift where the fold occurs, dissimilar to the Motorola Razr clamshell.
