The “green bubble” has become part of the everyday vernacular – the term is so popular it was featured on Drake’s 7th album. Honestly it doesn’t matter, which was released on Friday. The third song is dubbed The texts turn green and if you don’t know what that means, here’s an explainer from an unexpected source – Google’s Android team.

The song refers to speech bubbles changing from their usual blue to green when the recipient user blocks you on iMessage. But there is another reason why texts turn green – an Android user joins a one-on-one or group chat.
This often leads Android users to being excluded from group chats or even bullied. Google called on Apple to solve the problem by adopting RCS on its iDevices. RCS is touted by its supporters as the successor to SMS, it has many features we’ve come to expect from chat apps that just don’t work well on SMS/MMS.

RCS allows users to send and receive high-quality images and videos, view keystroke indicators, and read receipts and reactions. It works over an internet connection (cellular or Wi-Fi) and supports encryption. The proprietary iMessage protocol also does these things, but is only available on Apple devices.
When chatting with an unsupported device, the app switches to simple SMS for text messages and reactions and sends pictures and videos via MMS (which is an old protocol and compresses files to tiny sizes of a few hundreds of kilobytes). These messages appear in the dreaded green bubbles.
PS. Here is the song in question, The texts turn green:
