Whether I have my Android phone's settings to allow or disallow rotation, the Youtube app always rotates the video to fullscreen when I set my phone sideways.
When searching for this online, I even read somebody say something in the lines of "It's so great that Youtube doesn't care about that silly rotation setting, when I rotate my phone, I want the video to rotate as well, and go fullscreen!".
Well now. Isn't this a huge inconsistency?
I would argue that the system-wide rotation setting should apply to every app, in the same way. And I understand that videos are sort of a "special" kind of content, but a case can be made to want to lock the screen rotation and keep the video fullscreen (landscape orientation) and windowed (portrait orientation) regardless of phone orientation.
How would one go about determining if this is actually a bad UX design?
(More than simply soliciting anecdotal opinions and theories that is)
