The original iPhone’s epic plastic screen story is nonchalantly repeating itself with Ceramic Shield 2.
Everyone knows the famous story of the original iPhone, where Steve Jobs was not happy when the plastic screen got gouged by his keys in his pocket. The iPhone was already announced to the public, and they only had 5 months to fix this issue before the iPhone ships. It was an impossible timeline, but the inevitable had to happen:
The iPhone had to ship with a glass screen.
An excerpt from Apple in China by Patrick McGee (affiliate link) describing the ordeal:
Two weeks after unveiling “the one device,” Steve Jobs walked into a routine divisional meeting. He was in a bad mood and didn’t look good. Then he pulled out his prototype iPhone, which looked worse. The keys in his pocket had cut a huge gouge across its plastic screen. He threw the unit onto the boardroom table toward Steve Zadesky and demanded: “Make it glass.” It wasn’t the first time the idea had come up. In September 2006, just four months earlier, Jobs had grown angry about smaller scratch marks and complained to a mid-level executive: “Look at this, look at this—what’s with the screen?” The executive responded, “Well, Steve, we have a glass prototype, but it fails the one-meter drop test one hundred times out of one hundred times.” Jobs cut the executive off. “I just want to know if you’re going to make the f**king thing work.” Now, in January, Jobs wasn’t taking excuses. Apple had just announced the phone would be available in June; the date couldn’t be pushed back. Six months would’ve been a rush job; but they had even less time than that. The display is a module that had to be ready months ahead of the assembly.
What followed is perhaps the best-known anecdote on the manufacturing of the original iPhone. Jobs reached out to Wendell Weeks, CEO of Corning, a glassmaker in upstate New York, saying he needed the hardest glass they could make. Weeks told Jobs about Gorilla Glass, something Corning had developed for fighter-jet cockpits back in the 1960s. They’d never found a market for it and abandoned the project. Jobs convinced him to begin production immediately.
The decision risked throwing Zadesky, who managed all the mechanical parts for the iPhone project, into a tailspin. He and Tang Tan, another iPod veteran, had to quickly put together a touchscreen supply chain, as glass and plastic function in totally different ways. Fadell likens this “crazy” phase to landing “a fleet of 200 jets on an aircraft carrier, all within minutes of each other. And all the jets were running out of fuel.” Apple needed to find manufacturers that were highly competent, but with enough capacity to free up their top talent.
Every iPhone screen has always been glass, but glass still scratches no matter how OCD you are about it. More specifically, most screens on phones scratch at a level 6 with deeper grooves at a level 7 on Mohs scale of hardness. It’s a common phrase you hear as a tech nerd courtesy of Zack, but that stopped in 2025 with the release of Ceramic Shield 2.
Apple introduced Ceramic Shield 2 for iPhone 17, 17 Pro, and iPhone Air, which provides 3x better scratch resistance than previous iPhones. It seemed like a standard upgrade with the same fluffy marketing, but it really does make a real world difference. I never use a screen protector on my screens and upgrade iPhones every year, and my iPhone Air’s front glass is completely scratch free 6 months later.
This has never happened to me before.
Not a single scratch.
And that’s while using it caseless!
There probably isn’t an epic story behind the birth of Ceramic Shield 2 - just years of iterating and perfecting the glass chemistry to make it more durable - but the effect it has had on iPhone displays is seriously underrated.
