Gorilla Glass 5 Doesn’t Hold Up on Galaxy Note 7 – Corning Comes to Defend Itself

A scratch examination (video given below) showing the durability of Gorilla Drinking glass five has quickly caught the attention of Corning, and it didn't have long for the glass manufacturer to justify why the protective layer effectually Samsung's Galaxy Note 7 wasn't able to shield it from the torture test you tin see clearly below.

Corning Responds to the Torture Exam – Here'due south What the Manufacturer Had to Say Apropos Its Latest and Greatest Gorilla Glass 5

Earlier we start, we want to thank the YouTube channel JerryRigEverything and to Zack for going through the extra to perform the torture examination on a Milky way Annotation 7. If it wasn't for y'all, then you lot certainly would not take gained the attention of Corning. In the torture test, Zack uses a metal pick that possess a rating of 3 on Mohs scale. If you remember your physics lesson accurately, diamond has the highest rating on the Mohs scale, meaning that only diamond can scratch a diamond, and to ameliorate your knowledge, our fingernails take a rating of ii.5, which means that the metallic choice will hands exist able to scratch it, given its hardness.

Nonetheless, what'due south concerning near the test is that even Gorilla Glass iv possess a hardness of five-6, suggesting that a metallic pick should take no effect on information technology, and here we accept a Gorilla Glass 5 that'due south unable to concord its own. At present according to Android Authority, Corning'due south senior spokesperson, Jaymin Amin, and the company'due south VP of technology, Jon Pasansky were reached in social club to give a statement related to the durability of the drinking glass. Each time a rebuttal was fabricated to the spokesperson stating that the test was carried out well over thirty times, here's what the spokesperson had to say:

The exam "has been validated several times during the development process here at Corning."

"The hardness option that was used in the video was a three, that's considerably softer than the glass fabric. Oftentimes when you lot have a softer material like that, and depending on what kind of loads you have used, y'all tend to see material transfer on the test substrate.

Textile transfer on the test substrate is not necessarily a scratch only it can announced to the untrained eye as a pretty visible scratch. We don't know whether or not that is what is beingness seen in the video. Certainly in the testing we've done internally, nosotros don't see that event at all with similar picks on the Mohs hardness calibration."

Additionally, Pasansky according to the source stated that the video shows metal choice pieces rubbing off the glass material and that it's not the actual glass that's being scratched.

"Information technology's a function of the difference in the hardness of the materials, only in particular the load is very important. So you could accept a lower hardness selection with a much higher load and still achieve a condition that would await like a slightly college hardness pick with a lighter load. Information technology'south a combination of pressure and cloth hardness differences that exist between the pick and the cloth that's beingness contacted."

Galaxy Note 7 isn't the easiest smartphone to repair either, because according to iFixit, the phablet only gains a reparability score of 4 out of ten, signifying that if the smartphone needs to be opened upwards, then yous'd best hope that you've taken it to an expert.

When asked if Gorilla Glass 5 possesses the aforementioned scratch resistant backdrop equally Gorilla Drinking glass iv, it was concluded that aye; Gorilla Glass 5 might non possess a higher magnitude of scratch resistance as compared to its predecessor, just information technology'due south equal when you want to compare the two. While Gorilla Glass 5 might have been tailored to protect the display from a superlative of one.6 meters, the same proportional effect cannot be said for its scratch-resistant properties.

In the finish, what take nosotros learned? Milky way Note 7 might take a beating when it comes to physical impacts, but not necessarily when a sharp object roughly scratches the glass. Seeing every bit how a metal choice which possesses a hardness of 3 on the Mohs scale can easily scratch glass, yous will have to protect the flagship phablet from all kinds of precipitous objects.
