Which app has this notification icon?

who knows does not seem like a popular app. ask your friend to look in the notifications on the phone.

we get this every single day. there are millions upon millions of apps each with their own notification icons. so unless it is an app like facebook or youtube, you will most likely get guesses from us. sometimes you might get lucky, but majority of these questions goes unanswered.

good luck

 

I don't think there's enough resolution in the icon to identify that as a rose in the mouth, as opposed to just a dot by the head.
I don't think I'd read anything into the short hair either (which is the reason I assume you identify it as male). "Generic vaguely humanoid" is as far as I'd go (after all, it's hard to produce any "head" icon that someone won't identify as one gender or another, so it's easy to read too much into such things).

I did try a reverse image search on it, and all I can say is that it looks a bit like a low-res version of the icon you find here: https://www.google.co.uk/imgres?img...uPw&vet=1&docid=0TJp3HsvHFPekM&itg=1&hl=en-GB
