I asked if people chose iPhone for the blue bubbles elsewhere a couple days ago, and while there was some good discourse on that post, the blue bubbles definitely also came up as a reason.
In my experience, when people find out my texts are green, they oftentimes would rather switch to a different platform altogether like Instagram or just not text at all.
Is this actually a deal-breaker in friendships out there?
Right. Android is still 70%+ of the world market.
But iOS is 87% and rising for US teenagers, which explains iMessage being the dominant messaging platform in the US.
