When I tried to install the protective film on the screen of my phone, I used the small "cloth" that comes with the protective film to remove small dust on the screen. But the "cloth" has left a multitude of micro-scratches on the screen. This surprised me greatly but especially deeply disappointed as the phone is brand new !! I just to acquire it. So I end up with a phone whose screen is scratched over with the protective film revealing the micro-scratches. It's extremely frustrating.
