Yeah this is what the main issue is. If the updates weren't coming for any of the models at all, I guess we'd hear lesser complaints, whine a bit for a while, forget the device ever existed and move on. But The development is there, the updates are there and it's all happening for a particular market that ZTE want to please. And it's completely blatant. That's inexcusable. ZTE isn't realizing the damage this can do in the long run if they continue to be biased. Bad news always spreads fast. Axon 7 and ZTE wasn't known before this device so buyers took a chance. The next device they try to sell will have a massive number of the same people not wanting to buy and spreading the bad news to others to follow suit.People can't wait for development side witch is not exciting at all (and will never happened at Axon 7 to be honest) to optimize the user experience using the device.
This is something that ZTE must involve and improve.
Me too I'm going to wait until earlier 2017 and Android N and if nothing happens game over for ZTE once and for good.
Personal I don't mind(care) for bootloader unlocked(never did with all my smartphone until now) but most bothered me is the discrimination from ZTE to European version and that US has superior software support.
