It's not all that unusual for OEMs to come out with limited special edition versions of their flagships. But when you consider that it's a small startup like OnePlus and that it's a not so flagship OnePlus X, then you might have reason to be a bit surprised. But that is exactly what the company is doing with a OnePlus X Ceramic edition. But it isn't doing it just for profit, at least not completely. It will be auctioning off five of the very limited number smartphones, with all proceeds going to charity: water.
