Whats New about Gorilla 4? Are They unbreakable?
Take a look at the published specifications of Gorilla Glass, there are 4 most important matrices describing the glass properties contributing to its toughness, in a layman's terms, how strong/amazing it is.
When comparing the above values between Gorilla Glass 3 and the recently debut Gorilla Glass 4, the biggest difference we see is a Young’s modulus. (This basically imply the glass will be less easier to bend and more "flexible").
Additionally, the Chemical Strengthening section, reveals a much greater compression depth layer, from 40 µm to 90 µm for Gorilla Glass 3 and Gorilla Glass 4 respectively. This "super layer" significantly increases Gorilla Glass 4’s resistance to cracking and crack propagation, with a thicker compressed surface layer. The image below shows cross sections comparing damage resistance between Gorilla Glass 3 and 4. This layer essentially makes the crack blunter and shorter and basically reduce the magnitude of stress amplification.
However, if you use a screen protector, the differences become less significant. Screen protectors help spread out any impact stress, enough to prevent significant stress build up in one spot to cause a fracture. However much you toughen glass, you can't completely eliminate all these natural defects, which is why Rhino Shield will be a great addition for your screen :D
Samsung S6 drop test
Samsung S6 is the latest Phone utilise Gorilla Glass 4 front glass. As we see in the drop test below, it still crack on a face drop.
Fortunately, the Phone and Gorilla Glass can be protected by Rhino Shield and Rhino Shield CrashGuard. Check out the drop test. Big Difference can be made with the bumper case and screen protector installed.
In conclusion, it is always a good idea to get a bumper case to protect the device.
