I noticed that I could inject video animations for the background screen of my incoming calls. I had also assumed it would continue to animate as I answered an incoming call. Sure enough, the incoming calls do play the video I had set for the background screen. However, to my dissatisfaction, the background comes to a halt once answered and I am left with a still image.
If needed, I can provide a download/gif of the video I was planning to use for my background call screen.
