Corning responds to video that shows Gorilla Glass 5 on Galaxy Note 7 getting scratched easily

Samsung proudly announced that the Galaxy Note 7 is the first smartphone to use Corning’s Gorilla Glass 5. More often than not, newer versions of Gorilla Glass are associated with improved scratch and shatter resistance. However, a video from JerryRigEverything showed that the Gorilla Glass 5 panel on the Galaxy Note 7 gets scratched easily, even with a metal pick that is rated 3 on Mohs scale of mineral hardness. Now, Corning has officially responded to the worrying scratch test video.

According to Corning, the scratch test that we see in the video was conducted “in an uncontrolled manner.” Representatives from the company also stated that a pick with a hardness of 3 can’t scratch glass panels with a hardness of 5 or 6 (like the Gorilla Glass 5). Then what were those scary scratches on the Galaxy Note 7′s display that we saw in that now famous video?

The hardness pick that was used in the video was a 3, that’s considerably softer than the glass material. Oftentimes when you have a softer material like that, and depending on what kind of loads you have used, you tend to see material transfer on the test substrate. Material transfer on the test substrate is not necessarily a scratch but it can appear to the untrained eye as a pretty visible scratch.
