If you put a napkin (or paper towel/other tissue) over the top of the screen cover while trying to get the bubbles out, you are much less likely to scratch the screen cover during the process. Done this many times while using a 'hard card' (like a drivers license) to put on a screen cover, and haven't scratched one yet. This way you are basically 'scraping' on the napkin/tissue instead of the screen cover you are putting on your phone....
