Having problems – WhatsApp Messenger Review

I did your updat September 13th. And I can't answer my phone calls as a normal call on my screen I have to go into what apps to answer. I have a iPhone 6s Plus and did there update which was supposed to be compatible with yours. I can text, call and all that, the only thing I can't do now is when speaking on speaker I use to be able to black my screen and put it in my pocket and still talk without nothing touching up against any apps but now I can't black the screen because it cuts the call on WhatsApp ? Wish they would fix theses problems
