Answer to: Where to purchase Genuine, OEM Factory Samsung Galaxy S4 Gorilla GlassThere is no genuine gorilla glass for samsung galaxy s4 because samsung doesn't sell the glass separately. You would be able to find better quality glass, but it's not genuine and unfortunately it will never be the same even if you manage to separate the cracked screen from the display without damaging the lcd screen underneath. What you can do is to buy the whole thing. That means front glass, bezel frame (or without it, it's slightly cheaper) lcd display and frame. It is expensive I know, but is the only way to go, if you wan't your phone back just the way it was. Otherwise you will probably end up with a dim, vague screen or even worst, a damaged one.
