Dead zones using controller on iOS are too large

When using an Xbox controller to play Minecraft, the dead zones for the left and right sticks are too small and need to be made adjustable. On my controller, for instance, barely moving the analog stick down will cause the player to look down quite quickly. This does not happen when playing on any Xbox console or playing on windows 10. Please either make the dead zones for the controller adjustable or make them larger so that they match that of consoles or the windows 10 edition.
