For some reason your invisible shield's corners are different from mines, mine is covered nearly completely.. did you trim yours??
I honestly dont mind the feeling on the screen.
It doesn't feel rubbery to me, just feels like its wrapped in a material made to protect it from scratches..
No problems with friction, i dont apply that much pressure to my screen
The phone is glossier, which i wanted it to be anyways.
BTW it looks like the OP has a lot of dust under their shield, i would consider redoing it in a cleaner, less dusty environment.
Ill take pics of mine when im back home with a camera.
