Open the project with XCode and run it on an iOS device (no emulator, as the emulator on ios doesn't have camera support)
Once on the device - rotate to landscape view.
The example has locked the view to portrait mode - so the image shouldn't rotate.
Now press "Capture". The displayed image should be in landscape mode, but it is shown in portrait mode.
I haven't made the example run on android, but I know android works as we've tested it on a separate project.
