actually s9 and s10 device built up with ip 68 certificates of dust resistant Corning gorilla glass 5 and 6 respectively...but have to understand the grading..it's doesn't mean Corning gorilla glass 5 and 6 is better scratch protect than gorilla glass 3...actually fact is that gorilla glass 3 is better protect display than v5 or 6...believe it or not but it's true.....but ip68 certificates for s9,s8,note8,note9,s10 sp....are great, but not best because of the tendency of scratch by quartz diameter of 0.1u|m...it will very minute but you can notice those very closely...so please apply a screen protector which having compatibility to your device and will not create sensitivity issue
Please get it done asap,its very much required,go for Samsung original tempered glass or buy any screen guard compatible with s10,I am using clear view cover plus screen protector as gorilla glasses are not fully scratch proof..
