the quality of the glass is significantly below the original: fingerprints are everywhere and fat quickly .... easy enough to ask but watch the tutorials on YouTube for one must be very careful to deposit the old window without damaging the LEDs. Caution is missing what paste the glass on the sides: I used leftover double face (provided for sticking the upper and lower parts) after slicing. I also added qq PVC glue dots. Note a small defect of all these kits: Original between the screen and the window there is a transparent resin layer that unfortunately you are forced to delete. suddenly there is a vacuum of 0.1 or 0.2 mm. Attention also has to clean household alcohol inside the glass: a trace or dust will remain for life!
