No, I didn't use the spray on the screen. The instructors only mentioned to use it on the body.
Yes it is the best (unfortunately) available but not the greatest. One corner seems like it was lifted but it never was. It did go on smoothly and without bubbles with the little squeege. The hight is perfect but the width is short about 1mm. If I had known or noticed I could have centered it but the gap is all on the right side. The anti glare tint works excellent for indoor flourecent lighting but it terrible for outdoors. A clear tint would be better. It says the version I bought is thicker but thinner would be better as it dulls the sensititivty of the touch screen. Besides it's not the face that is going to bounce on if it falls. It may slide if on the floor and gets kicked or something like that but the buttons would take most of the damage and I wouldn't mind buying another protector if it got scratched as that is it's purpose.
I would recommend a clear thinner choice over the one I have. Maybe the anti finger print version, since mine loves finger prints.
Solution: Buy the product that I reviewed in this thread. The Ultra-Crystal protector feels like glass and is cut perfectly. Literally a hair on all four sides. 1mm sounds like a lot, and I'd love to see pics.
True, if you drop the phone, the screen will more than likely not be what makes impact. But you have a much higher likelihood of dragging a piece of dirt across the screen than dropping it, imo, which is why this protector is important. Gorilla glass isn't scratch-proof, especially against sand.
Solution to a spray-on film for the phone? Buy a silicone case. Thin, soft, and sticks to the phone like glue. And will probably provide more impact-protection than film.
Sorry to hear you had problems with what you purchased. Next time, buy an Ultra-Crystal, and be happy. The pics speak for themselves.
