Galaxy Note 7 Scratch Test Failed Miserably, Corning Responds To That Worry


The Galaxy Note 7 is hot on the heels right now in the market, and while Apple’s iPhone 7 on its way to get its fair share next month. That doesn’t mean it is Samsung’s time now, because it comes with all the downsides as well the upsides, though, and appears that Samsung has received something of a ding after a YouTube video surfaced to show its Note7 having its screen scratched all too easily, even though it features Gorilla Glass 5 protection. That’s what where the Corning responded to this in a new style.

The Galaxy Note 7 with Corning’s Gorilla Glass 5 said to be making it more difficult to break than previous generations, 3 and 4. Well, that’s even better when you’re building smartphones, but while it’s more difficult to break, what about knife scratching?

However, the Galaxy Note 7 is the only one smartphone that come featuring Gorilla Glass 5. A YouTube video by Zack from JerryRigEverything appears to show the Note 7 having its screen scratched by a metal pack with a rating of 3 on the Mohs scale of hardness. Standard glass sits somewhere around 5 to 6 on the same scale, so scratching the screen using a pick that has a rating of 3 is not good news. In fact, it should be impossible.

The same YouTube has already presented the similar scratch tests on devices typically using GG4 (Gorilla Glass 4), it usually takes a 5 or 6 hardness pick before scratches occur. For some context, as Zack notes in the video, a glass from Corning that appears to scratch much more easily than its predecessor is acceptably undeniable news, but the “scandal” may have gotten blown a little out of proportion.


In the Galaxy Note 7 scratch test video, non-removable marks are visible on the screen from a pick as low as 3. Based on this evidence, many have jumped to the conclusion that increasing Gorilla Glass 5’s shatter-resistance has come at the price of weakening its power. The folks at Corning were contacted and asked that obvious question, why and what’s going on? The likely answer is a simple one. The phone wasn’t being scratched at all. The pick was failing apart. What does it means?

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.

Also went into further detail, but the upshot is that they don’t quite believe that their screen was getting scratched at all, but rather it was actually breaking the pick that was being used to try and scratch it. Showing off that the pick was apparently leaving residue on the screen itself, making it look a bit it was scratched. If it’s a residue, that can be easily removed, so simply wiping the screen wouldn’t be enough to clean it. According to Corning for now.

May be the unit being tested would be faulty, and a relatively soft pick could be capable of scratching glass is suspicious, let alone Corning’s fancy super-touch glass. But again, glass still shouldn’t scratch like that. It depends on your thoughts and feelings and we likely never have an answer that will please everyone for the time being, no, the Galaxy Note 7 does not have its own screengate phenomenon. Not even one bit.

Do you agree with the fact that it’s technically not a scratch matter? If so, to avoid the display glass damage on your phone, buy a case, get a screen protector and please, avoid scratching your new Galaxy Note 7 with a soft metallic pick. Otherwise?
