I noticed a few months ago that every time I tried to call my wife while driving, using touchless control, I would get an error "touchless control has stopped" and the call was not initiated. This did not happen when I tried to call anyone else. I could call her manually, just not by voice. When I first got the Moto X, I was able to call by voice, so an update must have broken the software. Finally today, on a hunch, I removed the apostrophe from her last name (it begins O') and I can now call her using touchless control. Finding out what to pick up for dinner on the way home from work is now easier ;-) I tried reversing (added the " ' " back in) and it again failed. Removed it again and it works. I wonder if anyone else who calls Irish people while driving has run into the same issue? I will note that she was set up as google contact and is a "favorite" (well, of course!)
