Android users considered a turnoff to phone users

When people with iPhones text each other, their messages send in blue speech bubbles. But when they text non-iPhone owners, messages send in a different hue: bright green, as if to signal that they’re talking to an outsider.

For singles, it’s more than just an aesthetic thing: It’s a dating red flag (or green flag, as it were).

“If it’s not a blue message, I’m not going to bother flirting with you further,” Brooklyn resident and freelance designer Katie McDonough tells The Post. “I’m just like, ‘Why don’t you have an iPhone?’ ”

While Android phones have a larger market share than iPhones, millennials feel a stronger emotional attachment to Apple products than any other brand, according to a 2018 analysis by marketing agency MBLM.
