Camera orientation change is too slow

Question

I have a DrawerLayout which contains a FrameLayout and ListView in my app, I have to show the camera preview in the FrameLayout, I've done that fine (as following code) and the camera works correctly. The problem is when moving from portrait orientation to (right-Landscape orientation or left-landscape orientation), or vice versa, it take the mobile a long time to make changes, the problem does not appear when moving from right-Landscape orientation or left-landscape orientation or vice versa. How I could make this operation is as fast as I can.
