Samsung Galaxy Z Flip’s Durability Test Raises Questions About Foldable Glass Displays



Samsung Galaxy Z Flip's Durability Test Raises Questions About Foldable Glass Displays

Last week, Samsung announced that the new Galaxy Z Flip uses “Ultra Thin Glass” which sounded like a real breakthrough. Until now the previous foldable phones have used plastic displays that are fragile and easily scratched even with a fingernail. The Z Flip will be switching to glass which was expected to improve the scratch resistance of foldable displays. But the latest developments show that it might not be the case.

Zack Nelson from JerryRigEverything has gotten his hands on Samsung’s latest foldable and performed his signature durability test on it. But the test results do not inspire confidence. In the test, the top layer of the UTG screen didn’t hold up well. It scratched at a level 2 on Mohr’s scale for mineral hardness. At level 3, there were noticeably deeper groves while the level 3 went right through the top display layer. Glass scratches at level 5 or 6 means the top part of the glass is not likely made from glass.

Samsung clarified that the top layer indeed has a top protective plastic layer on top similar to the Galaxy Fold and should be “handled with care.” The South Korean giant also assured that it will offer Galaxy Z Flip owners a free specialized screen protector at select stores and UBIF (UBreakiFix) repair shops. It will be applied by a specialist using proper equipment. Early adopters will also be getting a one-time screen replacement at $119.

In another test, PBKreview performed a teardown of the Galaxy Z Flip to reveal the interior of the device. It shows that the display is held down to a thin metal frame and the reviewer managed to peel off the panel from the enclosure and managed to crack the display. This proves that there is indeed some glass material in the display but it’s still not clear how it is actually made. Then the protective layer is peeled off from the display which resulted in visible damage to the corners of the screen.
