[mikara89]

Description

CameraView does not change view dimensions. FillAndExpend and also if I set RequiredWidth and RequiredHeight CameraView stays the same. CameraView when Width and Height are check in debug values are good but preview on screen still 1/3 of screen.

You can try to work around this issue by applying a negative margin to the CameraView control on the right and bottom side. In your case, setting the margin on the right to -2 * Width of the page, should strech the control to the expected size. Do it for Height accordingly.
