Gorilla® Glass Victus® 2; Alternative Aluminosilicate Glasses and Corning® Gorilla® Glass 3 | Scratch Comparison | Corning Corning | lf nib n | May 11, 2016 .
Sand will scratch any type of glass. I had a old S4 that was nearing the end of it's service life. It had no scratches after over 3 years and bare glass feels better so within 3-4 months with no protector it had 3 easily visible scratches. In spite of keeping it as clean as possible using a microfiber cloth for cleaning. Lb12.
