There`s just one more thing...
I mentioned in my first post that I had `hi galaxy` customised to a personal command. This is not the same as the `unlock` command. You could wake Svoice with your own wake up call instead of `hi galaxy`.
I think that patch 4.3 has removed this custom ability. It might also be why I had the problem after that firmware. I don`t know, but no matter how hard I try, I can`t change `Hi galaxy` to my own command any more. Now i`m forced to say `Hi Galaxy` instead of my less geeky custom. Not very personal.
Blast you, samsung. Maybe I can send them an email about it?
