OK, so I have had this issue. While in game, (not options menu) There is a small arrow at the bottom of the screen that toggles various Android control schemes. Depending on your screen or how curved it is, the toggle-arrow may not be visible😑.
But even so, my honest opinion is that the controls in general suck when playing on Android😮💨. I have had the most issues when doing the stages that requires precision and timing😵. And the boss battles are more of a struggle then they need to be😣. Unfortunately this is not an easy fix since good controls on Android is far and few😓.
