i´ve installed the rom (stock partition) on my mi4 with banks (beta)-gapps
so far everything works very well, battery life is awesome and performance even better (stock kernel settings untouched)
the camera works also (took 2 reboots, before it kept fc´ing)
bluetooth also fine (only tested on my miband)

very good work!
thanks to you, gnome, banks and everyone else who participated
