Content suggestion thumbnails can now been seen on Youtube for Android while playing videos in full screen. These suggestions already appear while watching youtube videos on our computer.
Since the version 12.05 was released, it is now beginning to show suggestions as if we were on a desktop computer, the ones that are seen at the end of each video. It is possible that this function has not yet arrived, since it is not reached in parallel with all users. It is possible that the update has not even come to you.
The suggestions are displayed when we are in full screen and horizontal and as long as we click on the screen to show the controls, of course. As we will see in the image below, these suggestions will be displayed at the bottom of the screen. This feature increases the viewing time within YouTube, but it minimizes the viewing time per channel, so it directly affects the channels.
At the moment we do not know if it can be disabled or because it has not yet arrived to me, but the most probable is that it is possible. We will have to wait for it to finally come to us. You can try to download the update from an alternative market that is not the Play Store, but keep in mind that it is likely that you still cannot access the function, because I remember that arrives in a staggered way to the users.
On the other hand, it is not yet known if only the standard users will be the only ones who will receive the novelty, or if the users of YouTube Red will also have it.
