Last week, Samsung unveiled Galaxy Z Flip as its second foldable smartphone alongside the Galaxy S20 series. It features a folding mechanism similar to Motorola RAZR but with a better hinge. Another unique thing about the phone is its "Ultra-Thin Glass" that is claimed to be more durable than the plastic display used in other foldable phones. But as per the new Galaxy Z Flip durability test video by Zack Nelson of YouTube channel JerryRigEverything, the claim does not seem to be true.
In the video, Nelson starts with his signature display scratch resistance test using Mohr's hardness pick. A glass display is known to start getting scratches at level 6 with deeper grooves at level 7. This happens with all modern smartphones that make use of glass. But in the case of the Galaxy Z Flip, scratches started to appear at level 2 and deeper grooves at level 3. This is a characteristic of plastic suggesting that the foldable phone features a plastic display like the Galaxy Fold.
This behavior appears to be in direct contrast to what Samsung claimed at last week's Galaxy Unpacked event. Since tech critics were already curious about glass panel can bend without breaking, the test result has certainly made those concerns worse.
In a statement given to The Verge separately, here is how Samsung has explained the display tech:
"Galaxy Z Flip features an Infinity Flex Display with Samsung’s Ultra Thin Glass (UTG) to deliver a sleek, premium look and offer an immersive viewing experience,” a spokesperson said by email. “Samsung’s first-of-its-kind UTG technology is different from other Galaxy flagship devices. While the display does bend, it should be handled with care. Also, Galaxy Z Flip has a protective layer on top of the UTG similar to Galaxy Fold."
Even though we still cannot comment on exactly what the Galaxy Z Flip display is made of, we recommend you take proper care of the luxurious smartphone. Also, Samsung is offering a one-time screen replacement for $119 which is a discounted pricing.
