original discussion (in italian): [ROM] [Z7MAX] [Android 6.0] CM 13.0 unofficial or english: [ROM] [Z7MAX] [Android 6.0] CM 13.0 unofficial

The CM 13.0 (marshmallow Android 6.0) is a rom in full development, with several features still missing and probably some things not working.

after several days of work here is the first release for our Nubia Z7 max.

support for dual sim is in an initial state: you can use two sim, making and receiving calls, use the data connection and SMS
for the moment you can not turn off a single sim (only airplane works), the selection of the preferred network is bugged and I have no way to test the LTE if it works

what's working:

camera
flash led/torch
gps
wifi
dual sim
sensors
nfc (maybe)
Bluetooth
led notification/charger
FM Radio
Infrared​​

for enable the contact sync:
open settings->apps->menù button->show system->search google contact sync->permission and enable the contact permission
reboot the phone
settings->account->google->contact sync-> disable and reenable to force the sync
