I have been having issues with OK Google not working for some time now. Every time I try to "train" it, it says "Can't use microphone. Restart device." which, of course does nothing. I have turned off Moto Voice, and tried just about everything I can find when I google the problem to no avail. The mic works just fine; if I tap the mic in Google it hears me perfectly. Just the OK Google thing will not work.
Anyone else have this issue and get it resolved?
Easy fix not just this rom on the s7 also. You must hot delete voice under where you are trying to redo ypur voice. This is a but on Google's end as it is still picking up ok Google as your redoing it and it conflicts with the microphone as Google and retraining is trying to both use it at the same time very easy fix just hit delete voice 1st.
