The onscreen control sticks are just indicators! They are made small so they do not obscure the screen. *** You do not need to keep your fingers on them ***Sliding your finger any where on the right screen half affects the right control stick , the same for the left screen part - sliding finger there moves the left control stick. We suggest to select beginner settings at first few days before you can comfortably progress further.
