Remember - the discussion is about what platform is dominant. The fact that messaging is implemented an app doesn't change that. New developments occur on iOS first for a reason.
The numbers don't lie, but you are focusing on the wrong one. Loss making businesses by cannot be dominant. Samsung is the only profitable Android maker and it is collapsing while Apple continues to grow.
If its loss making then why are companies continuously releasing new Android mobiles. They should have shut shop. Samsung isn't even dominant where i live. There are many local brands releasing one Android mobile over another.
Anyway it seems useless continuing this. I suppose you would come back some other Apple this and that line. I just wanted to know where you got the stat. Since i am not getting any references i assume you made it up.
My question was wrt to source of your stat.
