It's all Samsung and Huawei in my country. I've heard the popularity of Apple in the US is partially due to the use of imessage by people and the strong dislike for "green text" because of how Android messenger doesn't work well with imessage or something.
People here mostly use Whatsapp for communication so the whole green-text thing is never talked about.
There's no “Android messenger”. iMessage just degrades to SMS when the receiving device isn't an iPhone. So it's really that those people choose to use the only messenger app that is only available on one brand of phones.
