filechooser.open_file should retain EXIF data when opening images in iOS

I'm building an app that needs to select an image. The images displayed in Plyer Filechooser are showing in the correct orientation, but once an image is selected it does not retain the correct orientation.

For Android, it's not an issue. I'm not using Filechooser for Android, but I can grab the EXIF info and re-orient the image using the code below. However, this code does not work in iOS when using Filechooser. It seems like Filechooser is creating a copy of the file into the App's directory, but that file does not contain EXIF data. Therefor, I can't rotate the image correctly. This code always fails inside the try expression.

from PIL import Image as PilImage, ExifTags
dst = 'path/to/image'
try:
    pil_img = PilImage.open(dst)
    for orientation in ExifTags.TAGS.keys():
        if ExifTags.TAGS[orientation]=='Orientation':
            break

    exif = pil_img._getexif()

    if exif is not None:
        if exif[orientation] == 3:
            pil_img=pil_img.rotate(180, expand=True)
        elif exif[orientation] == 6:
            pil_img=pil_img.rotate(270, expand=True)
        elif exif[orientation] == 8:
            pil_img=pil_img.rotate(90, expand=True)

    pil_img.save(dst)
except: pass
