We want every single Android device to have a great default messaging experience. We’ve been working closely with the mobile industry to upgrade SMS so that people around the world can more easily enjoy group chats, share high-res photos, and get read receipts on any Android device.

We’ve learned a lot from Allo, particularly what’s possible when you incorporate machine learning features, like the Google Assistant, into messaging.
Google’s desire for a great default messaging experience on every Android device has seen them launch and kill several apps with no clear argument, definable strategy, or even a sense of which one they think users should actually use.
