You can now swipe up while watching a video to enter full-screen mode, and swipe down to jump out of full-screen mode and back into YouTube’s “regular†view.
You can still tap the full-screen button to jump in and out, per usual, but the option to swipe makes the transition easier and more seamless.
The new swipe controls, overlay toggles, and upgraded chapter select menu will arguably have the most immediate impact on YouTube’s mobile experience, but those aren’t the only changes the update introduces.
