Ever since Apple introduced brand new iPhone 8, 8 Plus and iPhone X with glass installed on both the back panel and the front screen the sales of Corning Gorilla Glass exploded. First of all new iPhones are using twice as much glass than the previous models for front and back. Second, people now were breaking twice as much glass on their new iPhones than before since now they have to replace the back glass panel as well if cracked.
Case in point, I personally bought iPhone X with an expensive $50 case for protecting the phone from drops. The screen of my iPhone is still in great shape, but 1 unfortunate drop last week shattered the back glass panel on my iPhone and now I need to replace it at $150 a pop which I did not have to worry about on iPhone 7 and 6.
In other words, the latest Apple fashion statement by covering their last line of iPhones with glass front and back noticeably increased Gorilla glass sales which caused the stock to jump over 11%, today, July 25, 2018 after reporting strong 68% growth in earnings before the market as well as 10 percent increase in revenues.
