On your Android phone (mine is an Alcatel One Touch Inspire 2), you might possibly encounter the Turn on smart calling option under Call settings > Other settings. But what exactly does this feature do?
Smart calling allows you to initiate a call with just a simple gesture of waving your finger or hand at the front-facing camera of your phone. You can trigger it from the Messaging app (it will call the number on the active SMS thread), or while accessing your Address Book (it will call the first number of the contact being displayed).
But should you turn on smart calling? Chances are you'd trigger this accidentally more than the times you'd trigger it intentionally. Could be quite a hassle. I suggest you keep it off.
