Why is it so hard to answer calls with lollipop 5.1 LG K-7?

[AC Question]

99% of the calls I get I try to answer but it will not work. I touch and swipe and I end up loosing the call and must call the person back.

I HATE this. Whoever created this is an *****. I looked everywhere in the settings and I cannot find anywhere that will allow me to change it.
