A new possible development. There was an update for the main Google App this morning. I noticed that there were a lot of people complaining that there voice search (ok google) stopped working in the ratings The new update apparently fixes this (never stopped working for me, only had issue with Car Mode) I updated the Google app and restarted my phone. Car mode is now working again. The woman's voice is different, but all works. I'm wondering if the Google app has always been the issue since the new 5.1.1. Update.
For reference, Note 4, 5.1.1. Telus Canada.
