I have a Galaxy S5, phone is paired to my 2010 Citroen C5, no problems with calls and the car mode starts automatically when I start the car.
All good so far. The phone even responds to my "Hi Galaxy" command but the little red microphone does not hear me. I can tap it, shout at it, whisper, nothing, no response. All works fine when not connected to the car via bluetooth, but the point is I would have thought, that this function works best when driving.
Has anyone else had this issue or better still, are there any geniuses out there that know how to make this work?
