My old iPhone 6 showed me all my photos (40,000+) presumably through my iCloud but when i activated my new iPhone 7 today only 3,477 of them show up. I am logged into my iCloud account on my new phone and have Photo Stream turned on... what else do I have to do to access all my thousands of images on my new phone?
