So as the glass and has the same no distinctive marking.
The edges are sharp and the template is good.
As against the dismantling of a window on Samsung's really hard.
I disassembled the 3GS and 4 and 4S without lumia big problem. But there must be heated (100deg) the glass, the wire (like cutting butter) crashes EVERY glass. With picks and there must be forced for me it was the drama, so I had to change the full slab (110 and this is a good price with guarantee) it is expensive but it is the most practical.
I have one second to go, I will not miss it this time.
Ps videos on the windows come off too easily.
