You can set the orientation of the screen, as well as Left/Right Controls, from the Settings menu.
When set to Landscape, the screen will be fixed to a landscape orientation during races. When set to Portrait, the screen will be fixed to a portrait orientation (as has been the case since the game's launch) during races. When set to Portrait / Landscape, the game will switch between these two modes during races depending on the current orientation of your device.
When the orientation is set to Portrait / Landscape, or Landscape, you can adjust your Landscape control method with the following options:
・Same as portrait mode
・Left side: Steer / Right side: Use items
・Left side: Use items / Right side: Steer
Notes:
・The tutorial and Practice While Downloading races do not support landscape mode.
