Red Phone key does not work on Galaxy 4

[AC Question]

In the past, If I didn't want to answer a call, I could swipe the red phone key and the call would end. Now it doesn't work. The phone will continue to ring. I can silence it by the power button but and not ends it.

Welcome to the forums! What device and Android version are you using? Is it a Galaxy S4? Just in case, go to settings - my device - accessibility - answering/ending calls and make sure you have the right settings enabled.
