On some older Android devices, or more recent devices that have lower specs and aren't capable of running the game in higher resolutions, the graphic quality slider may be disabled, defaulting to Low graphics settings. This is to ensure that the game can run smoothly on your device, as the experience would suffer if you set the graphics any higher on your current device.

We're always looking for ways to improve the performance for lower-spec devices, but we can't promise that your particular device will eventually be capable of running on higher graphics settings.
