The OnePlus 2 features its StyleSwap back covers, which feature materials like kevlar and wood, and based on a new teaser image, the company has another material coming down the line. The OnePlus team has posted on its official Google+ page a new image, which seems to showcase some blurry imagery near its center, but what appears to be a clear shot of a leather back cover panel. Of course, as it’s just a tease, there’s not much information to go along with it, other than the caption that reads “Something luxurious is coming to OnePlus. What could it be?” On the image itself, OnePlus has included the tagline “A bit of welcome luxury.” It’s possible it’s not a leather back cover, but that seems to be running theory at this point. What do you think it could be?
