My personal pet peeve is that iOS strips exif time taken (probably all exif) through certain flows - I think iMessage does it? So then if my family texts me a photo of a trip way after it happened and I save it it ends up in the wrong part of my photo timeline. Whereas if they share it a different way like Dropbox it comes through with that metadata intact.

I care less about the location data as I usually know where the photos are just by looking at them but I understand there are good use cases for it and agree including location should be a user choice
