Screen protection has become a crucial battleground in modern smartphones, where virtually the entire front is a single piece of glass. A scratch from keys, a minor bump, or a drop from your pocket can all lead to damage. the difference between continuing to use your mobile phone or facing an extremely expensive screen replacementSo it's not surprising that manufacturers compete to offer the strongest possible glass.
In that context, Corning dominates with its Gorilla Glass and now adds two much-discussed protagonists: on the one hand, Gorilla Glass Ceramic, its new formula designed to withstand multiple impactsOn the other hand, there's the Ceramic Shield that Apple uses on iPhones, also developed with Corning but made of glass and ceramic. And in between these two, there's the Armor and Armor 2 family, which has made a huge leap in scratch resistance and noticeably reduces reflections.
What is Gorilla Glass Ceramic and how does it work?
Gorilla Glass Ceramic is Corning's latest offering for mobile phone displays. The company explains that it is a ceramic-reinforced glass designed to better withstand impact on hard and irregular surfaces than traditional aluminosilicates. It's not exactly the same formula as Armor 2, nor is it a direct replacement: they are lines with different approaches.
According to Corning's internal tests, this material can withstand up to 10 consecutive falls from one meter onto a surface that simulates asphaltThe key lies not only in the height, but also in the repetition of the impact and the type of surface, which is more aggressive than a smooth floor. Thus, Gorilla Glass Ceramic positions itself as an optimized solution for the most common scenario: real-life falls on rough surfaces.
Corning claims that, compared to rival glass from the competition, its new formula It improves protection when the impact occurs on irregular surfaces.While maintaining the panel's clarity, the brand does clarify that testing methodologies vary between product lines: withstanding numerous repetitions at a height of one meter on asphalt is not the same as withstanding a single impact from a greater height on concrete, so superficial comparisons can lead to erroneous conclusions.
An important launch detail: the first phone to integrate Gorilla Glass Ceramic will be a MotorolaCorning hasn't revealed the model, but has confirmed that its commercial launch will come in the next few months. This time it's not a debut with Samsung—as was the case with Armor and Armor 2—which adds variety to its adoption among manufacturers.
Gorilla Armor and Gorilla Armor 2: Less reflexes and more resistance
In 2024, the Galaxy S24 Ultra debuted Gorilla Glass Armor, A glass that stands out for its resistance and for reducing reflections by up to 75% compared to standard glass.This anti-glare effect makes a clear difference outdoors: less glare and more legible content in direct sunlight.
The second generation, Gorilla Glass Armor 2, arrived with the Galaxy S25 Ultra and was even more ambitious. Corning confirms that It can withstand drops from 2,2 meters onto a surface similar to concrete. In its laboratory tests, it also maintained the anti-reflective coating. Another advantage: Armor 2 is the first anti-reflective ceramic glass on the mobile market, combining mechanical performance with improved visibility.
It is worth emphasizing that Armor 2 and Gorilla Glass Ceramic do not overlap in tests; The first one boasts a drop height and a concrete-type surfaceThe first test highlights the repetition (up to ten impacts) at one meter on asphalt. The practical result is that each material boasts strengths in different test scenarios, and this influences the interpretation of the results.
Beyond what the technical specifications say, In real-world use, the anti-glare coating of Armor and Armor 2 is a tangible advantage. Compared to traditional glass: the panel looks better on the street, reduces the mirror effect, and helps to perceive fewer micro-scratches on a daily basis.
Ceramic Shield on iPhones: Apple's glass-ceramic
Apple introduced Ceramic Shield with the iPhone 12 and, since then, It features it in its main product lines as a glass-ceramic solution developed in conjunction with Corning.The latest generation, present in the iPhone 16, is advertised as being 50% more resistant than the original version, according to Apple data.
Manufacturing involves adding ceramic nanocrystals to the glass structure through a thermal processThis is a different approach to traditional aluminosilicate. On paper, this improves resistance to breakage from cracks and chips, crucial when the screen is subjected to twisting or impacts on the frame.
Corning does not offer direct comparisons between Ceramic Shield and its Gorilla lines (Armor, Victus, etc.), so There is no official ranking that puts everyone on the same level with the same methodologyIn independent tests, such as those by JerryRigEverything, the iPhone 16 screen shows deep grooves starting at level 7 on the Mohs scale; in contrast, a Galaxy with Gorilla Armor showed deep damage at level 8, suggesting better scratch resistance in that specific case.
There's no word on an anti-reflective coating comparable to Armor's Ceramic Shield. That doesn't mean visibility is bad, but it does mean that The anti-reflective coating of Armor and Armor 2 is now a clear competitive advantage. in conditions of high ambient light.
The evolution of Gorilla Glass: from the first iPhone to Victus 2
Corning first made a name for itself in 2007 with the first iPhone, which already featured Gorilla Glass. From then on, its evolution was constant, with different goals in each generation. scratch resistance, thinness, ability to withstand drops or repeated use without breaking, sometimes with compromises between properties.
Gorilla Glass 2 (2012) offered the same resistance with 20% less thickness; Gorilla Glass 3 (2013) It tripled scratch resistance compared to GG2 and reduced brand visibility by 40%. With Gorilla Glass 4 (2014), the focus shifted to drops, doubling the resistance compared to previous generations.
In 2016, Gorilla Glass 5 arrived with a very commercial headline: It survives falls of up to 1,6 meters in 80% of casesAnd in 2018, Gorilla Glass 6 embraced repeated drops: a glass with a new composition that, according to Corning, withstands 15 consecutive impacts from one meter onto rough surfaces.
With Victus (2020) and Victus 2 (2022), Corning tried to rebalance the scales between scratches and impacts. Victus was advertised as being able to withstand falls of up to two meters and with twice the scratch resistance of Gorilla Glass 6. Victus 2, meanwhile, fine-tuned performance on more aggressive surfaces such as concrete, an environment that is especially critical for heavy mobile phones.
How hardness compares: Mohs, Vickers, and real-world testing
Laboratory data is helpful, but it needs to be interpreted correctly. For scratch resistance, the Mohs scale is widely used (the number indicates the smallest material that can scratch the glass). In popular YouTuber tests, a Galaxy S24 Ultra with Gorilla Armor performed well. It showed deep grooves with level 8 tools, a leap from the usual trend of mobile phone screens starting to get scratched at level 6 or 7.
Another useful reference is Vickers hardness, which measures resistance to indentation. Gorilla Glass Victus 2 operates between 595 and 670 HVThe Dragontrail Star 2 (AGC) ranges between 570 and 640 HV. There is overlap, so it's not surprising that in everyday use both perform similarly in terms of micro-scratches when comparing similar generations.
In terms of pure impact, independent comparisons using the same methodology for all are lacking. Corning did publish one in 2013. a video where Gorilla Glass 2 and 3 fared better than an anonymous piece of glass (probably from the competition), but beyond that, cross-tests with identical protocols are not abundant.
Also interesting is the abrasion resistance test exhibited by Corning: when sheets are subjected to 45 minutes of wear in a barrel with objects, the sapphire glass It broke under a 73 kg loadwhile Gorilla Glass withstood more than 195 kg. Although it is a test by the manufacturer itself, it helps to understand why sapphire, being extremely hard against scratching, is more fragile when flexed and impacted.
Dragontrail, Kunlun and other alternatives to the gorilla
AGC, with its Dragontrail line, is the best-known alternative to Corning in mobile phones. It uses a tin float process to achieve a uniform surface and then It introduces particles that reinforce the structure of the glass.This led to versions like Dragontrail, Dragontrail X and Dragontrail Pro, with the latter being improved in 2016: a more resistant edge that increases durability by around 30% compared to the previous model.
The most recent evolution is called Dragontrail Star 2 (2024), which AGC It positions itself with significant improvements in resistance.This family has been featured in multiple devices, from the Pixel 3a series back in the day to terminals like the OnePlus 11R or OPPO Reno 9 in different markets, consolidating its role in affordable mid-range and high-end devices.
Huawei has also made its mark with Kunlun Glass, a glass that nanocrystals grow within the matrix to improve shock absorption. Not many technical details have been published, but it has resistance certifications from the Swiss company SGS, which guarantees a high level of robustness in its tests.
Tempered glass: cheap, effective and easy to replace
The tempered glass screen protector is still The most popular option when you're looking for an extra, inexpensive layerIt is manufactured by heating the glass to over 600 °C and rapidly cooling it with forced air, creating an outer layer in compression and an inner layer in tension that makes it more resistant to breakage than normal glass.
In terms of scratch resistance, all modern glass behaves similarly; where they differ is in impact resistance. Therefore, if your phone already has Gorilla Glass or Dragontrail, Placing a tempered glass layer on top does not drastically improve drop resistance. of the set. Even so, it can save you from a scratch or a superficial crack and is cheap to replace.
If the tempered glass bothers you or affects the tactile response, A plastic sheet could be an alternative.It offers less protection against micro-scratches, but adds minimal cushioning and maintains a pleasant gliding experience for many users.
Sapphire glass: the king of scratches, the Achilles' heel in impacts
Synthetic sapphire is often used in camera lenses and watches because of its hardness: mark 9 on MohsSecond only to diamond. Its manufacture involves growing an "ingot" from corundum in furnaces that reach about 2.200 °C for 16 or 17 days, obtaining a block of around 115 kg that is then cut and polished into thin sheets.
Full-screen mobile phone displays have seen little use due to their cost and fragility upon impact. In comparative tests, Gorilla Glass withstands bending better before breakingWhile sapphire tends to fracture with less pressure, it's not ideal if you have slippery hands. Therefore, although it's almost immune to keys in your pocket, it's not a solution.
Corning showed in its abrasion resistance test that, after subjecting surfaces to harsh conditions, The sapphire gave way with a 73 kg load while Gorilla exceeded 195 kgThis is an indicative figure with a manufacturer's bias, but it matches real-world experience: extremely hard against scratches, more fragile against impacts.
Which mobile phones are launching each technology
The S24 Ultra was the first to feature Gorilla Glass Armor; the S25 Ultra was the first to introduce Armor 2. Meanwhile, Corning has confirmed that Gorilla Glass Ceramic will debut on a Motorola in the coming months, expanding the range of brands that test their newest product lines.
Apple, for its part, has been using Ceramic Shield since the iPhone 12 and has updated the formula in the iPhone 16, which is advertised as being 50% more resistant than the original version of this glass-ceramic technology. Other manufacturers alternate between Gorilla Glass, Dragontrail, and their own options depending on range and cost.
It is common for mid-range and low-end mobile phones to use previous versions of Gorilla Glass or DragontrailBecause they offer very decent protection at more controlled costs. You won't always see the latest version of glass on non-high-end devices due to price considerations.
What's behind the names: design, thickness, and testing
Just looking at the brand of the glass doesn't tell the whole story. The phone's design, the thickness of the screen, the curvature of the panel, and how is the glass mounted on the chassis They also influence the final result. That's why there can be phones with the same glass name but different behaviors in real life.
Another key point is the testing methodology: Falling once from 2,2 meters onto concrete is not the same. than falling ten times from one meter onto asphalt. Armor 2 boasts the first situation; Gorilla Glass Ceramic, the second. Both scenarios are extremely tough, but different.
AGC, the manufacturer of Dragontrail, does not typically publish detailed drop height data with protocols comparable to Corning's, which complicates matters. direct comparisons in impactsEven so, their glass products have proven to be a solid alternative, especially in more affordable price ranges.
How to choose and better protect your screen
If you're concerned about visibility and performance outdoors, Gorilla Glass Armor or Armor 2 These are excellent options thanks to their anti-reflective coating. If your priority is surviving many consecutive falls on harsh surfaces, Gorilla Glass Ceramic makes perfect sense due to its focus on repeated impacts.
For iPhone users, Ceramic Shield remains a solid option within the Apple ecosystem: good resistance to cracking and chipping and continuous evolution generation after generation. In pure scratching, some devices with Armor 2 seem to perform better in Mohs-type tests, but overall performance depends on many factors.
Beyond the glass that your phone has, Adding an extra protector always pays off.A tempered glass screen protector is cheap, absorbs micro-impacts, and can be changed in two minutes; if you're not convinced, a plastic film adds minimal extra protection without compromising the feel.
Opt for recent versions of Gorilla Glass whenever possible. And consider whether anti-glare is important in your daily life. And remember: no technology is indestructible; all have their limits when it comes to bumps against corners or unfortunate drops.
Today, the screen protection landscape is divided among several winning formulas: Gorilla Glass Ceramic shines in repeated impacts on asphaltArmor and Armor 2 dominate in anti-reflective coatings and high-altitude protection, while Ceramic Shield keeps iPhones at the forefront with its glass-ceramic approach. Dragontrail and Kunlun remain reliable alternatives, and sapphire glass remains the king of scratch resistance but has clear weaknesses in impacts. Understanding what each option offers and how it's tested allows you to choose better and extend the life of your phone with the right combination of glass and screen protector.
