help me out making my transition from iphone please I am used to doing a long-press-on-the-home-button to trigger the voice- search. That's a bad iphone habit. Here with Android, it is always switching to the currently-running-apps screen. 

I tried so many ways ( including the home2 share app) but I could not figure it out. 

Could you tell me an easy way to configure note 3 ( or s4) hardware buttons so that I can program them to do certain things upon long press, double click, even triple click etc...  What's the best app for that? 

And secondly (and more practically speaking), please tell me how I can configure that a long press on the home button puts the phone into the listening mode?

Thank you...
To put Android into "listening mode", do your Long press, then click on the Google logo at the bottom of the screen. That's Google Now, your Siri counterpart.

For Samsung devices with S-Voice, double-pressing quickly on the Home button will trigger S-Voice.
