Replace/remove s-voice on the Samsung Galaxy S3 (and hopefully noteII)
From the website My quest to replace S-Voice on a Samsung Galaxy S3 | listentopaul
...a post in a forum (link) that gave me the missing link to getting “Bluetooth Launch” to work! There were a few more steps to do: To automatically launch the google search with voice search activated, I found another handy app called “ICS Voice Search Shortcut” (link).
And there you go. S-Voice replaced!
This was all done on a Samsung Galaxy S III LTE (I9305) with Jellybean 4.1.2.
