Watch: Galaxy Note 7 screen fails scratch test

The Galaxy Note 7 features the latest Gorilla Glass 5, which claims to be more shatter resistant and more difficult to break than the previous generations. While Corning’s Gorilla Glass 5 can withstand drops and other means of screen damage, would it offer the same improvement on its resistance to scratches?

Galaxy Note 7 scratch test

You might have seen the YouTube video made by Zack from JerryRigEverything showing his durability test on the Samsung Galaxy Note 7. In the video, Zack uses metal picks to evaluate the hardness and scratch resistance of the smartphone’s screen rating it from 2 to 9 on the Mohs scale of hardness. Surprisingly, the Gorilla Glass 5 on the Galaxy Note 7 scratches easily using just the level 3 metal pick. This means that the screen is just about one step up from plastic on the hardness scale. Most of the smartphone’s glass screen being tested can survive scratches in a scale between 5 and 6 according to Zack. He also shows the comparison of the test results with the Samsung Galaxy S7 edge having the Gorilla Glass 4 screen that can resist scratches from the level 5 metal pick.

Based on what have resulted in the video, many have speculated that the Gorilla Glass 5 improved shatter resistance has come at the cost of weakening its scratch resistance. And while people went frenzy with the outcome of the test, AndroidAuthority had managed to contact Corning to clarify what is happening. One of the Corning’s spokesperson, Jaymin Amin quickly gives a simple answer – what we are seeing is not the pick scratching the glass, it’s the metal pick rubbing off on the glass material.

“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. We don’t know whether or not that is what is being seen in the video. Certainly in the testing we’ve done internally, we don’t see that issue at all with similar picks on the Mohs hardness scale.”

In addition, Amin also noted that “the test that was conducted in the video is obviously not a bonafide industry test. It’s using Mohs hardness picks but it’s in an uncontrolled manner. We also don’t know a whole lot about what loads the person has used. Whether those loads are changing as he goes through the testing.”

It also mentioned on the conversation by AndroidAuthority that a Mohs pick of 3 should not supposedly scratch a glass with the hardness of 5 or 6. And when asked if the Gorilla Glass 5 was at least as scratch resistant as Gorilla Glass 4, Amin somehow went around the question with his response.

“The glass is designed to improve the drop performance and not necessarily designed to improve the scratch performance.”

Below is the scratch test video of the Galaxy Note 7.

Having the unfavorable result from the scratch test and with Corning’s claim that the marks on the screen are residues from the metal pick and not a scratch, it was said that it can be very difficult to remove the metallic material being transferred on the glass. While we are still uncertain on whether it is a scratch or not, it will be a good idea to put a screen protector to avoid scratching your Galaxy Note 7 screen.
