why my youtube video's doesn't showing 1080 p option? I am running my mobile in latest version only still not showing up

Because your phone only has a 720p screen. It can't show 1080p videos.

Same problem on Nexus 6P running latest 7.1.2. Started happening recently. 720p/60fps is maximum. 1080p not available at all.
