Tired of LG G2 shiny back cover?
I buffed my shine off with fine steel wool (grade 00) , then buffed it over a final time with ultra fine steel wool (grade 0000). It's available at any Home Depot. It leaves you with a slick matte finish, no gloss, no excessive fingerprints.
I removed my back cover to do this, but its not necessary. It's actually quite easy to remove, almost like a removable back cover. I just pushed my fingernail in and got a gap, then proceeded around the edges popping each clip as I went... Alternatively you could just put tape on your camera lense to avoid scratching it.
