This is my first as far as joining any forums. I'm an old retired Navy CWO4. I just got my Nexus and so far its been rather perplexing. The first day, it locked up completely showing me the emergency call only screen. I scrambled threw the suggestions from google and finally did a hard factory reset. That seemed to solve the problem. The notification led didn't work after the reset so I installed "light flow lite" now that problem seems to have been taken care of.
I now have a phone that seems to be working as advertised and I like it a lot.
