How to answer locked iPhone SE without sliding

So no way to set a button to answer - just buttons to decline ?

It amazes me that these things that call themselves phones are so good at everything except doing phone calls.

I guess I will have to have ear pods in any time I expect a call. No one can hear me anyway unless I use the on-cable mic.

Problem is I usually share the work phone pods, Lightning cable :-( so if it is charging can't use that on-cable button to answer.

My Nikon Camera has many orders of magnitude less computing power but that allows me to choose what functions I want various buttons to do.

Do these designers never wear gloves ? Buttons can be pressed with gloves, screens cannot be swiped.
