Am I the only one hopeless at putting on screen protectors on iPhones? I always seem to end up with loads of dust underneath. Ie. Bubbles. I managed to do a back protector film ok (Still a few bubbles but don't really care on the back). No matter how I try it, it never works. Also what are the screen protectors actually made of? The screen protectors seem to scratch quite easily themselves (You can see them under light) but they do a great job of stopping the phone getting scratched.
