Touch fix on left side of the screen

In Minecraft mobile,we usually use right side of the area to look around and left side of the area to control movement using joystick.Problem is in most mobile games the left side can't be used to look around,so we are used to it.But in Minecraft mobile both side can be used to look around.We are usually accustomed to use right side.We think that the whole left side is a dead zone.
