The above image was shared by @evleaks, and it is supposedly one of the backplates for the new LG G3. As you can see, it uses a "brushed metal" aesthetic. Some websites have speculated that this indicates it will be a metal case design, but that's not necessarily true. LG used a faux brushed metal case design, that was actually plastic onece before with the LG Viper. There's no reason they couldn't do it again.
Regardless of what the material will actually be made of, it's a welcome departure from the traditional and boring black or white designs. What do you guys think of this if it turns out to be accurate?
