Although we didnít really see it coming, taller displays are becoming more the norm when it comes to smartphone hardware. As a result, the 16:9 widescreen aspect ratio wonít fit in an 18:9 (or in Samsung and Appleís case with the Note8 and iPhone X: 18.5:9) aspect ratio without black bars.
Some manufacturers have included a feature built into the UI that allows you to change the aspect ratio of the app so you can watch video without black bars.
For those manufacturers that donít have such a feature baked into the UI, YouTube has added support for crop-zooming YouTube Videos so that it fills up all the usable space. Although doing this may crop some of the video being watched, many will appreciate the ability to watch YouTube videos on the entire display instead of leaving out black bars.
We were able to do this on a Galaxy S8 Active and a Huawei Mate 10 Pro with the latest version of the app: version 12.44 - so it would appear this should work on any device with an aspect ratio wider than 16:9. If youíre up to date and are still on 12.43, the update may still be rolling out.

There is no other way of seing 16:9 content on a 18:9 screen with no bars - unless you crop some content from top.and bottom or you extrapolate the original image and lose the original proportion of the figures. 18:9 is an absurd proportion for anyth...
Do you know what you are talking about? Most youtube videos are 16:9! All user videos captured by mobile phones are 16:9! All phone captured photos are 16:9 or 4:3 or 3:2! Reading material is best on 4:3 screen with 16:9 being a reasonable compromise...
Most of youtube content is 16:9 Television ratio Stop lying to your face, dude
