It has gorilla glass 4, which is the current standard for phone glass, but if you drop it and it lands wrong on a hard surface, or mistreat it it will still scratch/shatter.
For that reason I don’t give two hoots about sexy looking phones anymore, as long as the hardware and screen is up to spec, it gets put straight into a wallet style flip case with a clasp, so a drop is highly unlikely to do any damage.
Walking around with £300 to £600 quids worth of hardware in your pocket,ill take protection over style.
I’ve just bought a Huawei p9,and it’s wonderfully slim and sexy, I’ll never really appreciate that though as it’s wrapped up in a protective leather cocoon that also functions as my wallet.
