As soon a brand new flagship phone from a major manufacturer rolls out, people go on finding how sturdy and well-built these phones are. When Samsung announced its Galaxy Note 7 phone, the company praised more about its protection material coating its screen. This smartphone is using Gorilla Glass 5 technology, which was supposed to make it durable enough and scratch resistant as well.
However, the recent video leaked online shows that this scratch resistant Gorilla Glass 5 which was used to protect this smartphone from any kind of scratches is making ruckus among fans. Also, it takes a 3 hardness pick to scratch the Gorilla Glass 5 in comparison to 5 or 6 hardness pick which requires scratching the previous version of the glass.
After 72 hours of uploading this video online, Corning replies against the negative results shown by the Gorilla Glass 5 that it was tested in an uncontrolled manner. As per Corning, 3 hardness pick can’t scratch glass with hardness 5 or 6. But if it’s so then why are the scratch marks clearly visible in the leaked video.
According to the Corning, its explanation is very simply:
“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.”
Basically, what this video is showing is the residue from the hardness pick and not the original glass itself. We have a question from Corning that if it’s the case then why this residue could not be wiped off with a clean cloth.
However, Corning provided an answer for this as well:
“It can be very, very difficult to remove metallic material transfer from glass. It is very atypical to see in a field return when we look at scratches of glass, that kind of characteristic, but purely visual, perceived damage that is actually a material on top of the surface.”
We recommend you to use the screen protector if you want to make your Galaxy Note 7 phone less prone to scratches. Though it is less resistant to scratches as per the video but this phone recently broke pre-order records in the home country of the manufacturer, i.e. South Korea.
