On Android and iOS, a new video player UI with all important features in full-screen mode looks to have been added to the YouTube app. A row of icons has been added to the bottom left corner of the page, which appears to be a server-side change.
On the left, there are like and dislike buttons, as well as a quick toggle to the comments, save to playlist, and share buttons, while on the right, there is a more videos tab that displays recommended video. The audio controls tab is also included in the midst of music videos.

The new UI was tested on an Android 12 smartphone running the YouTube app version 17.03.35. You still can dislike videos, but you will not be able to view the counter.
The controls give you a lot more power when watching full-screen video, and they eliminate the need to reduce the video to engage with crucial tasks.
