Touchscreens can’t [yet] replace a dedicated keypad for games.
That’s why you don’t see many platformers for mobile. The ones that do exist auto run for you or put virtual buttons on the screen, which I haven’t found to work well.
Not even digital controls could really replace analog controls. While as impressive as the Pubg controllers (essentially a gamepad with a dock) are I'm still amazed there is still no "the one mobile analog input" device is out yet.
