Some phone cameras save the information about the orientation as EXIF data instead of rotating the raw image. We noticed this on our Samsung Android phones. But during my investigation, I found out that iOS does the same.
When I view such a picture using the MAUI Image control, it is shown correctly. But when I view it in the Telerik ImageEditor, the picture is rotated or flipped.
It seems this bug affects a lot of devices. Users can use the ImageEditor to fix it, but it's very annoying and not acceptable for production. A possible workaround is to write custom code that rotates the raw image according to the EXIF data. But I think an Image Editor control should be able to show images correctly out of the box.
