Galaxy Note Edge - how to disable incoming calls on edge screen

[AC Question]

Hi,

I have a Note Edge (SM-N9150) running Android 5.0.1. It is working great but one very annoying feature which I want to turn it off.

When a call comes in, it lights up the edge screen with the accept button midway and the reject button at one end. I have a flip top case and most of the time, I accidentally hit the reject button when lifting the top and lost the call.

I have spoken with several Note users and they all have encountered this annoying feature.

Is there a way to turn this off?

Thanks.
