Gorilla Glass is Corning's line of chemically-strengthened glass widely used on smartphones and tablets. Each generation improves drop resistance and scratch hardness.
Generation reference (latest first): Gorilla Glass Victus 2 (2022): improved concrete drop survival. Gorilla Glass Victus (2020): 2× scratch resistance, 2 m drop survival. Gorilla Glass 7i (2024): mid-range standard. Gorilla Glass DX/DX+: anti-reflective coating on top.
Apple uses Ceramic Shield (Corning collaboration) — ceramic crystals embedded in the glass for ~4× drop performance vs Gorilla Glass 6.
Glass front + glass back is more elegant but doubles breakage risk. Cases protect significantly — drop tests show case-on devices survive 90%+ vs 60% case-off.
