AlwaysOn app for missed calls

Hi there,
I´m playing with the AlwaysOn app (ver 3.8.4) from Dominik to get visual notification for missed calls.
Anyone succeeding in trying the same?
I set a blinking border, that does work, but I get no app icon when a call missed. I thought there should appear the same icon you get when you missed a call?

What do you use for your AMOLED to get visual notifications?
To be honest, I would prefer NotifyBuddy, but since I have no play store, I cant make in-app purchases :frowning:
