This is a bug that has too long by dragging the exporter, I don't remember if it happened in iOS.
If you configure an app in HD (1280 * 720) and runs on a smartphone with lower resolution as the Galaxy S2, both shooting buttons and the Joystick are poorly positioned. Of course this in Android is fatal for the amount of these resolutions.
It will be possible to fix this once, thank you very much for your efforts.
