I have a HTC One (M7) and just purchased an LG G Watch R. The combination is working fine, except for the fact that my contacts are not recognized when speaking via "OK, Google".
I wrote a mail to HTC, they told me it's an LG issue. I wrote a mail to LG, they tell me it's the fault of HTC. I have no idea anymore what to do.
In Google Now, going to Accounts & Privacy should have an option "Contact recognition", between items "Safesearch Filter" and "Search engine storage". I don't have this option.
Any idea what could be wrong?
