I would recommend an admin (high staff to enlarge the keys and keypads (the movement pad and shooting pad. I also recommend that the zoom in part should be removed because when i miss tap the keypad the keypads disappear meaning i cannot move my character unless i let go. So as a result i would ask for admins to fix
1.enlarge the keypads(in settings)
2.remove the zoom in part
3. Make the keys larger too
These things can come helpful to players who are use to playing with the previous generations of phones
