Overview
- The updated viewer opens fullscreen over a blurred backdrop and lets users swipe to adjacent photos and videos in a thread.
- A top bar shows who sent the media and when, with quick download and delete buttons plus an overflow menu for Forward, Share, Star, and View details.
- A bottom row adds emoji reactions including Photomoji, a shortcut to the full picker, a Remix entry point, and an inline comment counter for that media.
- In conversation threads, photos sent at the same time are now grouped into a compact cluster after delivery to reduce clutter.
- The feature is appearing for users on stable and beta channels, with some reports suggesting server-side enablement, while a small fullscreen camera corner change remains limited to beta.
