Why am I unable to answer incoming calls LG G3?

[AC Question]

unable to answer incoming calls LG3

When my LG G3 phone rings I do not get any options to answer the call and if the phone screen is sleeping it does not waken up, I can make calls and receive call but just cannot answer them......

Welcome to Android Central! If the screen is off and you get a call, do you only hear the ring? What happens if you press the Power button--does the screen come on, but you still have to unlock the screen in order to answer?
