CameraView always sets upper-right to EXIF orientation tag.
- Launch project on physical iOS device
- Set breakpoint on MainPage.xaml.cs:39
- Take picture in portrait orientation
- Either copy base64 from Debug output or from variable inspection
- Save base64 in text file on your computer
- Convert base64 into a binary file (does not need a .jpg extension)
- View exif tags (I used
file <filepath>from bash from Git for Windows) - See that the orientation value is always the same
- Repeat steps 3 to 8 from different device orientations
