You know that the G5 has a screen protector factory installed. I found this out the hard way. There were some light scratches on my screen after a few weeks of use which really bummed me out. After all, it's practically brand new. So then I did something really stupid and tried to use a rubbing compound to get them off which made it worse. Bummer!
Then I noticed the factory installed screen protector.
I was actually scratching the screen protector. I was so relieved. I thought I permanently messed up my screen but didn't. I was so happy! I peeled it off to a perfect, unscratched screen.
I wish I would have known that straight off. I would have just left it on.
So.. If your screen is looking scratched, check to see if it is the protector installed at the factory.
