Device is listed as NX907J, and I am glad to say that the TENAA certificate is quite informative about it. New ZTE phone weights 163g and measures 155.3×77.2×7.95mm. It has a 5.5' HD display, 2GB RAM and 16GB internal storage. Phone is powered by an 8-core, 1.4GHz processor and runs on Android 6.0.1. Its cameras are 13mpx at front and 5mpx at rear. All of that is kept alive with a 2900mAh battery.
There is no price nor release date on the device, but we do know it will be available in at least black and platinum colours. Spec-wise, it seems to be a medium-low device; as such, it is quite possible that it will not be released onto Western markets. We'll see.
