I found that I need to change the camera aspect ratio to 9:16 in portrait mode and 16:9 in landscape. I see that my game gets rotated when the device rotates. But what is the even that I can trigger on to set the aspect ratio change at the same time? I’m ok with either a blueprint or C++ implementation for this.

For background, I just started a blank project for mobile devices, defined Android as a platform, set “Sensor” in the project orientation setting, created a camera actor and then packaged it for Multi. I’m testing this on my Samsung Galaxy Note 8 with Android 9.

Research says that Android exposes this as an “onConfigurationChanged” event → [How to detect orientation change in layout in Android? - Stack Overflow](https://stackoverflow.com/questions/5726657/how-to-detect-orientation-change-in-layout-in-android).  
Is this passed through by any chance?
