What doe he mean by 'back glass' ?
Is that the ACTUAL screen as opposed to the digitiser (front)
Oh, like the xperia Z.
Thing with glass is its very hard so does not scratch easily but also brittle and easier to shatter.
Talking about the back glass here.The glass does scratch. But the good part is that the scratches can't be felt or seen when the screen is on. It can only be seen when you bounce light off the screen when it's off.
