I can not understand some of recessions. Yes, it does not flush, but it does not hurt, and probably must be so because otherwise would not hold. Attaching is very easy, when compared with a normal film, the film is to be classified as very heavy and the bullet-proof glass as easily. It spoiled the smartphone not, rather scratches it would get otherwise would spoil.
My tests: screwdriver passed, passed key, box cutters -> I have no scratches in the glass get (with Lupe nothing to see).
The product does what it should and that makes it perfect, so 5 stars. Do I need a film for the back! Please produce !!!
