Has anyone upgraded their 928 to windows 10 mobile? If so, does the Hey Cortana option work with voice activation? The reason I am asking is I currently have an ICON with 10.0.15024.249 running and I was thinking that the 928 may support voice activation for Hey Cortana. But the 928 also has Glance screen ability I think. If anyone that could answer this, I would appreciate it. Thanks...
