My S4 says it is dialing after I swipe to answer an incoming call

[Android Central Question]

When I swipe to answer an incoming call from my lock screen my S4 then says it is dialing. I hear nobody from the incoming call and have to hang up and dial them back. This started maybe about a week ago. How do I fix this?
