I recently updated my Galaxy S3 to Kit Kat. Since then, when I actvate S-Voice with Hands Free Mode, the Calendar or Camera keep popping up even though I haven't requested either of them. I have to touch the right softkey to back out to return to the S Voice screen. I can't request any further action from S Voice until I do so. And sometimes it happens 5 or 6 times within 20 to 30 seconds. How do I stop this?
