Not sure if this is a bug or it's suppose to be this way with BB, but all the games I've exported to android don't rotate is this correct. Or do I need to turn something on, it doesn't hurt the game play just I see other game automatically rotate to the orientation of how it's held.
I saw this for various IOS games too, even BB's Phases, so my assumption is that this is a bug. I came across a similiar new bug on IOS: after displaying an ad, the system flips vertically, so this might happen on Android too.
Interesting it happens on IOS as well, it's not a big deal but it does make BB bit less professional.
I recently confronted this problem! The answer is for the projects made with Android Studio in my case. You need to open AndroidManifest.xml and replace android:screenOrientation="Landscape" to "sensorLandscape" For me , it works )
