YouTube has introduced a new view for comments when the user plays the video in full screen, so that they can have the two elements in the same space, after their test in June.
Comments in full screen mode appear as a sliding window on the right side, when the user plays the video horizontally, reducing its size. This way you can watch the video at the same time and check the messages left by other users.
The tests of this function began in June with a small group of users, as reported in Android Police. In a previous version, it was possible to hide the comment section by sliding it down, thus enlarging the video, which took up all the space again.
The new view of the full screen comments section has been implemented in Google’s Android app more widely.
