A few weeks after I got my first touchscreen phone, I had to google for how to answer it.

I had assumed you'd just tap the "answer" button, but that failed more often than not. It never would have occurred to me to swipe a minimum of 3cm, starting with the answer button, and I must assume this knowledge has spread to users by osmosis rather than discovery.

Accepting a call has been a different action on every Android phone I've ever owned.

Typically it is a tap and drag in some direction, but the direction to drag for answer vs hang up is always different between OEMs.

So that's fun. :/

The accept button animates on most phones in the way you need to move it. But it's true that I've seen many first timers get confused, probably because of the inherent pressure that accompanies a phone call.
