I downloaded the APK for Android and there is a problem. How do I solve it?

  1. I tried to use mobile landscape mode, but the screen does not rotate and is upside down.
  2. I made a Button node and it worked when I tested it, but the button doesn’t work on Android.

  1. you can change your orientation in your project settings.
  2. I think you need a touch button (activate emulate touch to use the button in the editor)
