I have an iPhone 8 which I really like. What I really love about this phone is that it is so beautiful…but then I see some scratches and those seem to ruin the beauty. From what I’ve read, those scratches are not scratches in the glass itself but in the Oleophobic coating (which is a somewhat finger resistant coating). For the most part these scratches aren’t noticeable but being a perfectionist, for them just to be there bothers me sometimes. I’ve read a little about applying (or reapplying) the Oleophobic layer onto a screen which sounds quite easier (drop some of this special liquid on the screen, rub it in, let it bond for 6-8 hours, and its done). I was wondering if I could do that to just fill in the scratches (not to cover the entire screen). What should I know before doing that? What would be the best Oleophobic coating product to use? Will it void my iPhone’s warranty?
No, those are actually scratches in the glass itself. If it is not visible with screen lighted up, don’t bother. If it is affecting image quality, replace the screen.
