In 2007, Steve Jobs in the process of testing the first iPhone was very uncomfortable when the glass of the device too easily scratched even if only in pocket pants. Just a few weeks before the official introduction of the machine, he decided to change the protective screen layer of plastic with tempered glass.
At that time, almost every phone had a plastic screen protector instead of the current glass. Many manufacturers are happy with this, but Steve Jobs is not. His decision changed the mobile phone market and made Gorilla Glass stand out like alcohol.
Gorilla Glass glass is manufactured by Corning, which is very experienced in producing special glass, used to be the manufacturer of microwave ovens for Pyrex home appliances, producing glass plates for telescopes. Space Hubble and a window for spacecraft. Corning is also the maker of glass for Thomas Edison's light bulb.

Despite such an impressive "seniority", Corning was in great financial trouble in 2007, the company had suffered losses for five consecutive years, thanks to its partnership with Apple and the iPhone's resounding success. Corning has returned to profitability.
After the iPhone, Corning quickly became the choice of many smartphone vendors. In 2008, the iPhone 3G and the HTC T-Mobile G1, the first Android smartphone, helped Gorilla Glass become more popular.
The following year, some Symbian-based phones like Samsung i8910 Omnia HD and Nokia X6, also use Gorilla Glass. Some phones are basic but "cool" like LG BL40 New Chocolate also use this glass, in 2010, Gorilla Glass appeared on nearly 200 million smartphones, according to Corning data.
Ratio of phones using Gorilla Glass
In 2012, Corning launched Gorilla Glass 2, which is 20% thinner than the first life but still retains its durability. In 2013, Gorilla Glass 3 continued to debut with improvements to reduce reflection as well as less fingerprints. Gorilla Glass 4 launches next year to increase impact resistance and the latest Gorilla Glass 6 with even higher durability.
However, in Gorilla Glass version 5, Corning was subjected to criticism because its durability was not as good as before, so it changed some chemical structures to increase durability on Gorilla Glass 6.
The distribution of life Gorilla Glass
However, Gorilla Glass is not currently the only toughened glass for smartphones on the market. Apple, which has brought Gorilla Glass to fame, is also one of the first names to "break up" with this type of glass and switched to using ion-toughened glass since iPhone 6. Another rival of Gorilla Glass It is Dragontrail glass, used on Pixel 3a and some previous Sony Xperia series.

However, up to now, Gorilla Glass leads the market. A smartphone without protective glass will make them vulnerable, such as the Galaxy Fold, for example, because the screen folds so it cannot be used with tempered glass. Corning is currently working on a foldable Gorilla Glass for future folding screen smartphones. Some smart wearable devices are also using Gorilla Glass, even TVs. Perhaps, Gorilla Glass is still the king of toughened glasses for smartphones for a while.
