Yesterday, OnePlus posted a teaser video featuring peoplereacting to a mysterious product hidden inside a box. As you can see in thevideo - embedded above - most people seem to like the texture of the product,and some say it's reminiscent of the sandstone variants of the OnePlus One andOnePlus 2.

In case you didn't know, unlike OnePlus' newer smartphones, theOnePlus One and OnePlus 2 did not have metal backs. On the sandstone versions of these two handsets,the back had the texture of real sandstone, with a grippy, distinct feel. Sowe're thinking that OnePlus may have been working on a sandstone variant of the5T. We'll find out if that's true in January 2018 (next month), when OnePlusplans to "unbox the mystery."

If you're thinking that the mysterious product could be anew OnePlus 5T protective case, we're pretty sure it isn't. That's because OnePlusis already offering a sandstone case for its current flagship phone.
