Can you check if you haven't already with your finger nail around the edges of the phone's screen to see if your phone has a factory fitted plastic screen protector @Šabu

First thing to check as BandOfBrothers has mentioned, to check if there's a screen protector fitted.
Glass in whatever name it has is still glass and will break and with the right materials will scratch.
Always advised to put a screen protector on to help reduce the chance of damage
