The Midnight Black version of the OnePlus 3T now belongs on the extinct list - the last few units are gone and the limited edition color option is officially sold out. The story behind Midnight Black is interesting, it was meant to be the original color for the third generation. Did you get one? Are you sorry you missed it? Perhaps you shouldn't be, the OnePlus 5 may arrive sooner than you thought. Source
