I just bought an Axon 7 phone and all automatic updates have been completed. Now I have Android 6.0.1 (Marshmallow) and Build number ZTE A2017GV1.0.0B11. I was under the impression that the phone could be upgraded to Android 7.1.1 (Nougat) but can't figure out how to force/trigger this update?
I haven't yet installed my SIM card and was wondering if that might affect updating the phone? (The phone is connected to wi-fi)
