Is Samsung Galaxy Z Flip’s ‘Ultra Thin Glass’ really glass?
Samsung unveiled its second foldable smartphone, the Galaxy Z Flip, last week with new-gained confidence and promises of important breakthroughs in material sciences. It claimed that its new phone features the Ultra Thin Glass (UTG), a flexible protective glass layer to save the foldable screen from scratches. Now, those claims have been put to the test, and the results aren’t looking pretty.YouTuber Zack Nelson, also known as JerryRigEverything, has published a video that shows him testing the durability of the Galaxy Z Flip’s screen and body. As usual, he starts the screen durability test by scratching it using various Mohs hardness picks.Most modern smartphones that use Gorilla Glass or other screen protection solutions start showing permanent scratches at level 6, which then deepen at level 7. The Galaxy Z Flip, however, starts showing permanent damage at level 2, with deeper grooves beginning to appear at level 3. This puts the Ultra Thin Glass at the same durability level as the plastic protection on the Galaxy Fold and Motorola’s new RAZR.
