Smartphone Makers Trick You With Glass Claims
Every year, phone companies boast about tougher screens. They say new phones are four times more shatter-resistant than last year’s model.
Then, the next year, they claim their phone is three times more scratch-resistant. These claims sound impressive, but they often hide a trade-off.
It’s like a balancing act. Making glass harder to scratch also makes it more likely to break.
If you make it softer to prevent shattering, it will scratch more easily. Phone companies can’t dramatically improve both at the same time.
Corning’s Gorilla Glass: A History of Alternating Improvements
Most high-end smartphones use Gorilla Glass from a company called Corning. Gorilla Glass first appeared in the original iPhone in 2007. It’s now on its ninth generation, and Corning’s marketing shows this pattern.
Looking at Corning’s past claims reveals a clear trend. They have consistently focused on improving either shatter resistance or scratch resistance each year. They alternate these improvements to create new marketing headlines.
The Reality: Two Separate Curves, Not One Big Jump
Instead of one big improvement, there are actually two separate improvements happening. One curve shows scratch resistance getting better, and another shows shatter resistance improving. These two curves go up and down, alternating their focus.
This clever marketing makes it seem like phones are getting much tougher overall. However, the glass is still susceptible to scratches from everyday materials like sand. Sand contains quartz, which is harder than glass, so it will always leave marks.
Ceramic Shield: Another Example of the Trade-Off
Apple’s Ceramic Shield on iPhones is often mentioned as being on another level. It was introduced with the iPhone 12. The first generation claimed to be four times more shatterproof than previous glass.
But the Ceramic Shield 2, which came with the iPhone 17, is now three times more scratch-resistant. This follows the same pattern of alternating improvements seen with Gorilla Glass.
Beyond the Glass: Other Factors Affecting Durability
Even independent tests show that phones can be more shatter-resistant. However, attributing this solely to the glass would be wrong. Many other design choices play a big role in how well a phone survives a drop.
Things like the shape of the screen, the thickness of the phone’s edges, and whether the sides are flat or curved all matter. For example, the iPhone 12’s return to flat sides likely helped its durability compared to the rounded iPhone 11.
What You Should Know as a Consumer
When you see claims of phones being three times more scratch-resistant or twice as shatterproof, remember the trade-off. Companies highlight one improvement while likely sacrificing the other.
Don’t forget about other features like oleophobic coatings that resist fingerprints and reduce glare. These small details also contribute to the user experience, even if they don’t make the headlines.
Specs & Key Features
- Gorilla Glass Generations: From version 1 (2007) to version 9, Corning has alternated improvements in shatter and scratch resistance.
- Ceramic Shield (Apple iPhones): Introduced with iPhone 12, initially focused on shatter resistance, later generations emphasize scratch resistance.
- Material Hardness vs. Brittleness: A fundamental trade-off where increased hardness (scratch resistance) leads to increased brittleness (shatter susceptibility), and vice versa.
- Common Scratches: Everyday materials like sand (quartz) are harder than smartphone glass, causing scratches.
- Other Durability Factors: Phone design elements like bezel thickness, edge shape (flat vs. curved), and frame material significantly impact drop resistance.
- Surface Coatings: Oleophobic coatings help resist fingerprints, and anti-reflective coatings reduce glare.
Who Should Care?
Anyone buying a new smartphone should pay attention to these claims. If you’re prone to dropping your phone, you might prioritize shatter resistance. If you often carry your phone with keys or coins, scratch resistance might be more important to you.
Understanding the trade-offs helps you make a more informed decision. You can look beyond the marketing hype and consider what truly matters for your daily use of the device.
The Bottom Line: Glass is Still Glass
The next time you see a headline about a phone’s incredible new glass, remember the science behind it. Companies are clever with their claims, but the fundamental properties of glass remain. Improvements in one area often come at the expense of another.
So, while phone screens are getting better in specific ways each year, no glass is perfectly immune to scratches or shattering. Always be mindful of how you handle your device, as even the toughest screens have their limits.
