Most cameras will let you export raw files, and a lot of phones do as well(although the phone ones aren't great since they usually do a lot of processing on it before giving you the normal picture)
My understanding is that really raw phone data also have a lot of lens distortion, and proprietary code written by the camera brand has specific algorithms to undo that effect. And this is the part that phone tinkerers complain is not open source (well, it does lots of other things to the camera too).
