Why is my Galaxy S4 automatically answering calls?

[AC Question]

Periodically, my Galaxy S4 will automatically answer calls while I am in the middle of a counseling session with a client. I turn the ringer off so as not to disturb my session. All of a sudden, I hear someone (the caller) repeatedly saying "hello."

Check Setting>Motions and Gestures and see if you have "Motion" turned on. If so, try turning it off.
