Samsung Galaxy S25 Ultra's Gorilla Armor 2 glass scratches more easily than original Armor

The new Samsung Galaxy S25 Ultra has exclusive use of the new Gorilla Armor 2 glass, which can survive drops from 2.2m (7.2ft) onto concrete. Corning claims that Armor 2 maintains the scratch resistance of the original Gorilla Armor that was used in last year’s S24 Ultra. But is that true?

Zack from JerryRigEverything has been testing the S25 Ultra and reported that the new glass scratched at a Mohs level 6. Watch in the video below:

But if we rewind back to the Galaxy S24 Ultra durability test, it scratched at a level 7 – here’s a time-stamped link to Zack’s video. If you pause the video, you’ll see that the S24 Ultra display definitely showed some marks from the level 6 pick. However, the reformulated Armor 2 glass for the 2025 phone suffered more damage from the same level 6 pick.

We might be seeing the effects of making Armor 2 more drop resistant than the original Armor. Harder glass is more resistant to scratches, but it is also more prone to shattering when dropped. Conversely, glass that can absorb an impact without shattering is softer, making it easier to scratch.

Makers have to strike a balance between the two, depending on consumer preferences. And Armor 2 still has the wonderful anti-reflective properties that made the original Armor great, plus Samsung has fixed some pain points with the S24 Ultra display like the graininess at very low brightness levels.
