Corning's most advanced cover glass — combining the toughness of Gorilla Glass Victus 2 with a nano-textured anti-reflective surface etched directly into the glass itself. Gorilla Armor 2 is the first mass-market cover glass that simultaneously reduces screen glare and survives drops onto concrete from up to 2 metres. It debuted on the Samsung Galaxy S25 series in 2025.
Gorilla Armor 2 is a fundamentally different product from every previous Gorilla Glass generation. All prior generations were engineered exclusively around mechanical performance — drop resistance and scratch resistance. Gorilla Armor 2 adds a third dimension: optical performance. It is the first Corning cover glass to address screen reflectance as a primary design goal, achieving this through a nano-textured anti-reflective surface that is integral to the glass rather than applied as a separate coating. The result is a cover glass that performs as well mechanically as Victus 2 while delivering display clarity in bright ambient light that no previous cover glass has matched.
The defining innovation in Gorilla Armor 2 is its anti-reflective surface treatment. Unlike traditional AR coatings — thin-film interference layers deposited on top of the glass surface — the AR treatment in Gorilla Armor 2 is achieved through nano-scale surface etching directly into the glass itself. The process creates a sub-wavelength surface texture: a structured pattern of nano-features smaller than the wavelength of visible light (~400–700 nm), which causes light waves to transition gradually from air into glass rather than encountering an abrupt refractive index boundary.
This graded-index effect dramatically suppresses Fresnel reflection at the air-glass interface. Standard flat cover glass reflects approximately 4–5% of incident light per surface. Gorilla Armor 2 reduces this to around 1% or less — a reduction of approximately 75% in reflectance. Because the texture is part of the glass structure rather than a deposited film, it cannot delaminate, cannot be scratched off separately from the glass, and does not degrade in the way thin-film coatings do over years of handling.
A critical engineering question with any surface modification — etching, coating, or texturing — is whether it compromises the mechanical integrity of the underlying glass. Surface etching in particular introduces a risk: nano-scale surface features can act as stress concentrators, reducing fracture toughness and making the glass more susceptible to crack initiation on impact. Corning's nano-texture process for Gorilla Armor 2 is specifically engineered to avoid this failure mode.
In Corning's controlled drop testing, Gorilla Armor 2 maintains survival from drops of up to 2 metres onto concrete — identical to Gorilla Glass Victus 2 and the best performance in the standard Gorilla Glass line. The underlying glass substrate uses the same alkali-aluminosilicate chemistry and ion-exchange strengthening as Victus 2. The nano-texture is applied after ion exchange, and its geometry is optimised to minimise stress concentration at feature tips. The result is that the AR surface treatment adds no measurable penalty to drop performance relative to unmodified Victus 2.
Screen reflectance is the primary cause of outdoor display unreadability. When a display is used in direct sunlight, the ambient light reflecting off the cover glass surface competes with the display's own luminance. At typical outdoor illuminance (~50,000–100,000 lux on a sunny day), a display with 4–5% surface reflectance returns thousands of nits-equivalent of reflected ambient light into the user's eye — washing out the image regardless of how bright the display itself is. This is why smartphones often become unusable outdoors even at maximum brightness.
By reducing surface reflectance to approximately 1% or less, Gorilla Armor 2 cuts the competing reflected ambient light by approximately three quarters. In practical terms, a display under Gorilla Armor 2 appears as legible in direct sunlight as a display under standard glass would at nearly four times the ambient light level. This means the display's peak brightness budget can work more effectively — images remain sharp, colours remain saturated, and the display remains readable in conditions where standard cover glass would require shading or squinting.
Anti-reflective coatings have existed on optical components — camera lenses, eyeglasses, monitor screens — for decades. Their limitation in consumer electronics is longevity. Thin-film AR coatings are physically separate layers deposited on the glass surface, typically 100–300 nm thick. They are bonded to the substrate by adhesion forces, not chemical integration. Over years of handling, pocket and bag abrasion, cleaning, and thermal cycling, the coating-substrate interface degrades and the coating develops micro-delaminations, hazing, and eventual visible peeling — especially at edges and corners where mechanical stress concentrates.
Because Gorilla Armor 2's nano-texture is created by etching into the glass surface itself, there is no coating-substrate interface to fail. The AR structure is chemically the same material as the rest of the glass — it is simply shaped differently at the nano scale. It cannot delaminate. It cannot peel. It does not change the glass composition. The only degradation mechanism is if the nano-features are physically abraded away by sustained aggressive scratching, which is the same failure mode as scratching the glass itself — governed by the glass's Mohs hardness (~6.5), not by coating adhesion.
