Positives: -Comes In time -Tools To complete this work. -The Video instructions on Youtube is well done The Bad: -The Blue color is not the same as my original screen. -The Samsung logo is not present Why do not buy this product: -The Matter is not the same that the original screen, glide finger on the screen is reduced, the transparency is not enough and the colors are less vivid and yellowed, the visibility of witnesses notification is significantly reduced, witnesses back and bottom menu are virtually invisible and blue. Finally the worst: -the absence of adhesive between the window and the screen considerably decreases the contrast and particularly the conductivity of the glass; touch respond correctly when you hold the phone in hand, but much less, if at all when the phone is placed. I regret having made that choice replacement, my phone is unsaleable even if aesthetics is better. For effective repair, replacement glass screen block seems to be essential ... if you can find an original product Samsung!
