So I've had my M8 for about 2 months now, and a few days ago I noticed a tiny scratch right above where the keyboard is, so I constantly see it when I'm texting. Usually this wouldn't bother me, but based on the location I'd really like to get rid of it. I tried the toothpaste method a few times but I'm not sure if I did it right - is there any other way to get rid of scratches or can someone please thoroughly explain the toothpaste method and I'll try again?
