"How is Corning? Gorilla? Glass 2 different?
Gorilla Glass 2 can be up to 20 percent thinner than the original, but still just as tough. This exceptional thinness enables greater design possibilities for slimmer and sleeker devices with brighter images and improved touch sensitivity. Gorilla Glass 2 is elegant and lightweight, but scratch resistant and durable enough to withstand the unexpected abuses of everyday life."
All they ever stated is that it is just as tough but thinner. What does this mean? It means a piece of gorilla glass 2 by itself will be thinner than a piece of gorilla glass by itself. Now each phone has it's own specs and manufacturing. When Samsung released the Galaxy S3, it was the only phone out with a 4.8" size and suprisingly thin. Now, we don't exactly know what process Samsung used, how it got the glass, did Corning mould it to specifications or did Samsung do it.
Once again, all Corning has ever stated is that it's glass is durable enough and is able to resist most everyday abuses. they've never said it was scratch-proof, nor shatter-proof. They've only said it was just as durable as the original and scratch-resistant, which it is. Additionally, as I stated earlier, each person is different as is each situation. The material in your jeans pocket may be different, maybe there is lint, dust, sand etc. Some of you could put it face in to your jean and get hairline scratches, some of you could put it with keys and come away with no scratches. Nothing can be quantified. Glass is, and always will be an easier material to scratch.
As for me, I've fallen asleep on my Galaxy S3 several times, I've sat on it. It has been much more flexible and durable than my GSII, if that means anything. For you it could be different. How can you ever prove it scratches more easily? And even then, did they ever say it won't? All they said is there isn't a loss of durability. That could mean anything.
Look I am not on the side of the faceless corporations, but my point is that people should do some reading before. Numerous review sites even stated their device got a few scratches on the screen. The least some of the people now complaining about scratches could have done is get a cheap static cling protector. They cost less than a dollar these days. Why risk anything?
