    Has anyone used a phone for, say, two years, without a screen protector, and care to tell us how good/bad their screen looked? I know that the first scratch KILLS you! Your brand new, spotless device, now it's blemished!

    But after the newness wears off... I just wonder if I'm not better off with the look, and FEEL of the naked glass, even if it does get a few minor scratches on it.

    Just wondering...

    I've had my phone for over 2 years and it finally cracked the screen today. It also has minimal scratches. It hasn't had a screen protector since the 2nd month of ownership.
    S3 with Gorilla Glass is is spotless. S7Edge with Gorilla Glass 5 has an unsightly scratch seen on some angles. My Galaxy S is spotless too.

    Gorilla glass 3 was the toughest. It was also the most brittle. The harder something is, the easier it breaks. Gorilla Glass 5 is more shatter resist, but also softer hence scratches more.

    Corning never promised unscratchable glass. That's impossible. You need a full on sapphire screen to achieve that. Glass has a Mohs hardness of around 5.5 Steel used for things like keys or pocket knives have a hardness of up to 6.5, while Gorilla Glass has a hardness ranging from 6-6.5 depending on variant according to some sites. Some sand particles have silica in them, which has a Mohs hardness of 8. So obviously it will scratch. Since GG5 is softer, I'd think it's the one with hardness of 6. So a steel key and sufficient pressure or friction can scratch it too.
