sony is using dragontrail glass since 2011 xperia but they didn't specify it
n most of the phone also come with shattered proof sheet,
the sheet protect the glass from shattering whn it break,
so u still can use it temporary if u still can c the display

the glass below the shattered proof sheet is scratch resistance
but the shattered proof sheet is not scratch resistance,
n i think it is not covered in the warranty, if u want u can remove the sheet by urself

c pic here, the corner place, warning big photo
