:-P Take it off and reapply it. I'm not sure what type of magic in invoked when they craft these screens, but it's not the traditional "Orange Peel" Invisible Shield-type skins or the plastic "5 come in a pack because they're garbage" protectors - they're very easy to reapply and fix, enabling you to carefully lift them and use stickers/scotch tape to remove dust/lint that gets trapped underneath during installation.

Here is the link for the protector I purchased for the G3, and I only didn't order from them again because they don't have any G4 products (yet!).
