It does look as though the mystery device would be part of the Axon range for the fact that the grille-work happens to be a giveaway, and it shares a mighty close resemblance with the device that appeared in the month before over at China’s FCC equivalent, that is, TENAA. A rose, by any other name would smell just as sweet, which is why ZTE’s model A2017 is also widely believed to be the upcoming Axon 7.
After all, the antenna stripe in the TENAA side view does make itself line up with the ad in The Wall Street Journal. Of course, all of this is pure speculation until something more official is revealed by the folks over at ZTE, so we will simply have to wait and see.
