that said, here's a challenge to Google - I *dare* you !!!!!!
to fix the "OK Google" feature so that *if* it brings up the search screen AND does not receive any input (as if you may have accidentally triggered it) then it CLOSES THE F***ING search screen so that you can see whatever your phone was doing beforehand.
It may sound a trivial niggle, until you are driving, using your phone as a SatNav, and the search screen pops up. You're forced to touch the screen. Not the safest thing at 70mph.
Before there are loads of comments about "why not disable OK Google when you drive ?", I'd point out:
1) It can be useful to have access when driving
2) That's the *whole point* of OK Google anyway.
