iPhone contact photo reverts back after cropping - Solution
Apple support was unable to solve my problem about "photo reverts back after cropping", so I tried every possible way how to fix it and finally found a solution! (you probably have the same problem if you are going from another device)
Solution:
1) Open a phone app (with all the contacts)
2) Click on "Contacts" (at the bottom)
3) Click on "Lists" (top left corner)
- there, you should find all the Lists in which you have different contacts
- if there are contacts in different List other than "All iCloud", you may continue
4) Go back into "All Contacts" (at the top)
5) Back up the information for the contact you're having trouble setting a contact photo for, then delete it (so its not present in any of the Lists)
6) Go back into "Lists" (top left corner)
7) Click on the List named "All iCloud"
8) Create a contact there -- and now it should work
9) You may go back into "All Contacts" if you want -- it still works
