When I turn on the app in portrait, the app won’t work.
If this is initial turning on, app is black screen.
If get out of the app to do something and re-enter the app, screen freezes in the ast moment and not working.
I think right off the bat, why would you ever consider playing a flight sim in portrait. That’s the equivalent of flying a B777-300ER with a Xbox controller, it doesn’t work.
Second of all, to my knowledge Infinite Flight does not run conventionally in the portrait orientation on a device. At least Apple devices, since I don’t follow Android that often - I believe they are the same requirements.
Works fine on my Galaxy Tab S6 either way. When device is on portrait mode but not locked, IF auto rotates to open in landscape mode. If portrait is locked however, IF is forced to open on portrait and also works even though it’s not intended nor recommend to try especially on the ExpertServer.
Undetermined! Too many factors here. The important thing is that it does work on landscape as intended, so I wouldn’t be too concerned about it not working on portrait! :)
