Ok this may sound dumb but on my iphone 4s I was able to hold down the pay button on my headphones and then say 'Call....' and it would call that person. Cant seem to do that on my note 2. It was very handy when it was raining or very cold. Any ideas how I can do this very simple thing? I tried it the same way on my note 2 but it doesnt work and couldnt find anything online regarding it.
