I Have been using this smartphone from past 5 days, i don't know much about it but few loving and some bad feature i want t show you
good one is
Display size is Big
Camera is great in terms of photo quality
High speed processor
What Bad i found
The os is older version
Storage only show 56 GB when i get it
Front camera not that much good like Mi 5
Price little bit higher
I will give it 7.7 point out of 10.
3gb, 64gb storage good feature but if we see the operating system, it,s Android lollipop, this is 2017 starting so they should at least give Android OS 6.0. Overall feature and hardware quality is great. ZTE always focus to provide best hardware.
