Overview

• YouTube says the refreshed player is rolling out worldwide this week across Android, iOS, the web and TV devices.
• On TVs, video details shift to the top left, core controls sit below the progress bar, a centered play/pause button returns, and Like, Dislike, Comments and Save are grouped in a pill.
• On mobile in landscape, most controls move into a left‑side pill as part of a cleaner layout that obscures less of the picture.
• The double‑tap seek gesture gets a less intrusive look, new icons debut, and some videos trigger content‑themed animations when users tap Like.
• Comment threading arrives to focus replies, while saving to Watch Later or playlists becomes smoother and mobile tab transitions get more seamless.
