I’m still having problems with videos rotating after 3.10 and 3.11. Its not possible to watch videos in landscape mode when the phone isn’t. Since English isn’t my native language I’m having problems explaining this correctly, but the standard video app in iOS works, the YouTube app works and VLC used to work until 3.10.
A “workaround” is to use the vlc rotation lock, but if that’s activated all the buttons are grayed out and none of the gestures work. Using the rotation lock is also a hassle when you’re laying in bed sideways watching videos and turning to the other side.
