In the current stable version of Google Messages, when you capture an image from within the app to send it in an RCS chat, a small preview of the picture pops up in the compose box. You can tap on the image to see it in fullscreen. Well, Google has started testing a significant change to how Google Messages shows the preview of the picture you capture from within the app to send it in an RCS chat to offer a better user experience.
According to 9To5Google, when you capture an image in the latest beta version of Google Messages (version 20240318_01_RC00) to send it in an RCS chat, it shows you a fullscreen preview of the picture, allowing you to see the image more clearly before you send it. The app now also gives you the option to “Write a message” about the image right from the preview screen, allowing you to refer to the image while typing the message.
If Google Messages’ new approach seems familiar to you, you are right. Samsung Messages offers a similar arrangement. WhatsApp too. These apps show you a fullscreen preview of an image before you send it. However, unlike Samsung Messages and WhatsApp, Google Messages doesn’t show a fullscreen preview when sending an existing image. Hopefully, the company will fix that issue with a future update to the app. 
Expect Google to roll out the new user interface the the stable version of Google Messages in the next couple of weeks.
