China Phone Suggestions

First of all sorry if i posted in the wrong sections, but i couldnt find a place where it would fit better
So i am looking for a new china phone but cant find "the one"
Right now i have a OnePlus One and i want the new one to be a nice upgrade
Here are my criteria:
QHD 5-5,5" Display (actually anything better than 1080p is fine)
Good Custom Rom Support
Processor should be at least as strong as the OnePlus One's
Maybe Gimmicks like Touch ID or Heartrate Sensor, but dont have to be
Double Tap to Wake would be cool too
I think all high-end smartphone have a really good camera, so i dont have to mention it

I would buy it next year in january or february, so it does not even have to be out yet
