Tip: If there was dust on the screen but simply replace the foil back partially and then "dab" the dust of the adhesive side of the foil with a piece of adhesive tape. Works great and has subsequently no blistering.
Everything was great and I was really pleased - until I made the iPhone again! Unfortunately I have to give my speakers right about the image distortion. The otherwise sharp display interacts with film grain significantly and fuzzier. Especially in writing (eg emails) I remember this clearly negative and that's just the Retina display particularly bad! I had previously also at all causing film "Artwizz ScratchStopper" on the display, which, though the display does not matt, but not Grainy effect.
I will atFoliX films a few days it can be to see if it really bothers me so much, but right now I think I will end up the other 4 films unfortunately in the drawer and I'm going to buy again Artwizz. On the other hand, it must be noted that all (without exception) anti-reflective films, through its matt finish, the display make course less accurate than Clear films.
