On the blog post, the Tech Giant mentioned that they want every Android device to have a great messaging experience and they have been working closely with mobile industry to upgrade SMS so that its users around the globe can enjoy the services like group chats, read receipts or shirring high-resolution photos like WhatsApp.
Hangouts, which is the consumer messaging app you may have adopted years ago and is attached to your Google account, is going to die at some point down the road.
"We built Google Allo, a smart messaging app, to help you get more done in your chats and express yourself more easily", Google vice president Matt Klainer explains.
As for Hangouts, the venerable chat app that launched with Google+, the company basically confirmed it would go away at some point last week, with users being "upgraded" to the Hangouts Chat and Hangouts Meet services now available for businesses. After ending its life entirely, the company will focus its energy on building Messages, the RCS-capable app that adds modern functionality to SMS on Android - kinda like Apple's iMessage.
"Given Messages' continued momentum, we've made a decision to stop supporting Allo to focus on Messages". In January, for example, Google's Allo lead Amit Fulay jumped ship to Facebook. The service is shutting down in March 2019, giving people time to export their conversation histories. He admitted then that "The product as a whole has not achieved the level of traction that we'd hoped for", though Google would keep supporting the app. Should Google decide to change Hangouts' fate, Hangouts users should be able to make use of Hangouts Chat.
Meanwhile, Google will focus on Messages. According to 9to5Google, we can soon expect Google to announce the beginning of the end for the company's short-lived chat app.
