I have landscape view enabled in the settings. Some time ago the video is upside down when starting a video. Now I always need to unlock the view and then lock it again.
VLC should remember and use the previous orientation of the video, since which way that is "up" when the phone is on its side can depend on the phone, the cover, the phone stand, personal preferences, or other things.
Using beta 3.3.1, on android, at the moment.
