Screen certe not equivalent to the original but it at least has the benefit of perfectly fit (nothing exceeds) in my case no visible adhesive residue and above all it works very well: I had a bad surprise with a screen from another web site ... Otherwise it lacks indeed the filter to the notification LED (flash suddenly that !!), when the sheet of LCD assembly is therefore a delicate short hair to plug in, I already a dead pixel and double sided n ' is not provided.
Finally for the price (+ 80 on the major part of specialized sites) I am completely satisfied with my purchase, my N4 is left for a few hours of intensive use. See in time ...
