I chose the set of two protection "Crystal" to keep the bright and shiny side of my phone screen, and no worries at this level there. The screen protector does not change anything and does not detect than at its edges. Installation is quick and simple, I'm just equipped me with a credit card to affix without bubbles. Size and level it perfectly matches the width of the screen, and for the length, it goes to the bottom button and the camera top, as in the picture. So no real complaints. And plus: I received five days!
