basically the newer pictures on all updates phones are not returning exif data
the same pictures are returning data as expected on other exif tools / software used to visualize / parse them
it started one by one with the new version of firmware/software for all Samsung phones in the last past few months.
it might be related to the fact Kodi is using version 2.1.2+matrix.0
