Note 8 youtube

I think they changed it to pinch to zoom now, so try doing that to see if it'll go completely full screen. If that's not working, force stop YouTube, then clear the cache. That worked for me. Hope this helps.

Yelp they did changed it to pinch to zoom. Pinch outwards to make video fit screen. Pinch in to make video go back to original size. I like it better this way.

No I only use gmail app for email and yes YouTube is upto date I just don't get it

Have you tried pinching out? My old YT had the little white box to fill screen, that went away, and when I updated, I got the zoom out.
