Low quality saves cost for YouTube and YouTube thinks that you won't notice the difference between 480p and 1080p on your phone. They don't fuck with your quality on desktops because they know you'll notice that
For example on desktop if you skip through a video while it's set to auto (1080p) at some point it will fall down to 480p. Maybe because YouTube thinks your connection has an issue, or maybe they just want to save bandwidth. If you manually set it to 1080p it stays there.
The player prioritizes smooth playback over quality. If you're skipping through, you're bypassing any buffer it's built up, so it'll drop the quality in order to be able to actually start playing sooner.
Pretty sure YouTube messes with it on desktops as well. Might default higher, but I had to use that advanced YouTube add on to force it to 1440p (or next highest) because it would constantly make me select it.

The whole thing is annoying.

Interesting, YouTube autoselects 4K for me if available.
