Friends i have taken Samsung Galaxy S6 Edge (G925) in India.

There is no Vibrate on Call Answer option in S6 Edge. Even i am not able to use this feature from third party apps also. i have searched in play store, Google and many forums. but i did not find anything useful.

please inform me is there any other way to activate this feature in S6 Edge
