I think that I can suggest a couple of things for Android version.
First, it may be better to keep only 90-degrees twists. And select axes of twists by large faces of cubes, not by stickers. That is if you click a corner sticker, axis of rotation will depend on the face of this sticker that you clicked.
Second, 4D dragging is a funny thing, of course, but for the real puzzle it’s enough to give users "recenter" command. I don’t know possible Android commands, but something like double-tap could do the trick (if such thing exists there).
With this two options (and without autorotation!) it may be very possible to solve a puzzle in one session before phone’s battery goes empty :)

The same problem I have with the mouse navigation in the desktop mode - most mice are too light to make confident clicks, sometimes I have to make 5 or 6 clicks to perform a single twist. In my programs I count mouse moves between "Down" and "Up" events, and if it is 3 pixels or less, consider this event as "click", otherwise as "drag".
