Summary: Photo rotation put some line of pixels at the wrong
edge

Original photo (unrotated, has flag)
STEPS TO REPRODUCE
Certain image sensors do not output a rotated photo according to how the device
is held (e.g. holding a phone in portrait orientation), rather, it only sets
the rotation flag in the photo. As a result, I have to manually rotate my
photos to the correct orientation, and set the flag to "Normal".
OBSERVED RESULT
After rotation, it seems that a few line of pixels are wrongly placed on the
other end of the photo. In other words, vertically, the photo should be
ABCDEFGH, but in fact, after rotation, it becomes CDEFGHAB. Please see the
included attachment.
I guess it's related to EXIF orientation or some other metadata, as photos shot
with one device may encounter this bug, but those shot with another device
won't.
