I'm using ZTE Maven running Android 5.1 Lollipop, and while there are 3 physical buttons on the front of the phone beneath the display, by default to answer a call you have to touch a green virtual button on the display and "slide to answer".
I get calls very infrequently and when I do I have a lot of difficulty answering calls. At first I concluded that I have to hold on the green virtual button until it activates, and then slide it, but recently that doesn't work either and I end up missing the call.
I understand there are apps for changing this behavior, but I'd prefer a configuration solution. I think once I found a mention of an accessibility setting for this, but the only documentation I can now find is for pre-Lollipop versions of Android and it doesn't seem to apply.
Is there a way to configure Lollipop with an alternative way to answer calls?
