Samsung S4 Active, 4.4.2
2 issues, how to control what app comes up with a bluetooth headset trigger, and how to turn on the voice prompts in google search.
I have a bluetooth helmet comm system. Push a button and it brings up the google voice dialer. Sometimes it will bring up 'google search'/'google now' (the OK google thing). Now I have it bringing up google search, but not sure how I got it there, or if it will stick. I'd like to try that for a while if I could get the audio response to work. I've tried setting speech output on and handsfree, but no workie.
