I can't reply phone calls on the home screen

[dflor]

I have a Samsung A6 smart phone. I can reply calls when I am on Gallery or homescreen only if I press volume button.
After calls, it appears the screen I have showed in the photo (2 buttons-green and red). When I press the green button, nothing happens unless I also press volume button (in that case, it appears another screen, when I at last can answear phonecall).

Re: I can't reply phonecalls on the start screen

Welcome to Android Central! Which phone? What do you mean by "start screen" -- are you talking about the homescreen?

When someone calls while you're using another app, you should see a notification appear at the top of the screen -- does that happen for you?
