"Pure" Android users who use Messages for SMS will receive new functionality within the app as well as the ability to send and receive messages directly to a PC. These capabilities are not new, with various other applications offering similar features, but this update will probably be the largest and most important thing so far for the Android OS messaging application
First, the most important and the one that comes up soon (it's already available) is the ability to use an internet browser to authenticate, read, send and receive messages on your phone. Thus, by accessing the link https://messages.android.com/ and scanning the QR code displayed within the message application on your phone, the message application is moved to the desktop. I have seen similar functionality in WhatsApp in the past, and it will probably be the safest way to use desktop mobile messaging applications.
Other upcoming releases are closely related to the new "RCS" capabilities of the messaging application. There will be the ability to send GIFs or stickers directly from the app and get all the links with preview, like an online messaging application. These capabilities bring the Messages app closer to Apple's iMessage, which could be accessed extensively on the desktop on Apple computers, and which offered similar capabilities in sending multimedia content
Messages from Google will still receive two important features in the near future. Smart replies, a Gmail inheritance feature that provides quick responses to interlocutor replies using the AI and the ability to copy two-step authentication codes with a single push of a button
While browser authentication is already available, the rest of the features will be launched during the next week. To access the new Messages, please update the app on the Google Play Store
