A problem that does not reflect when the device orientation is changed

[jasu]

Even if you rotate the device orientation, the preview screen will be fixed in portrait orientation. Even if you take a picture, the result is the same problem. Is there any way to solve it?

Is this a problem you're seeing when using the package or when using the demo app?

I also come across this problem when I use the demo app.

This is the portrait orientation.

This is the landscape orientation(the preview image direction is wrong and the view size is also wrong. It should be like the Camera app)
