some of this depends on your camera/phone
Back when digital cameras came along I bought 2 of the 6490 Kodak cameras 4.0 megapixels, with removable memory SD cards. Once the SD card gets so loaded it takes too long to bring up the program "Easy Share" I just replace that card with a newer one. So far now I have about 10 SD cards that contain all my digital photos AND they are also loaded into the Easy Share program on my computers. I suppose I should also download all the photos to a separate hard drive which I also have as a 3rd backup. A truly "smart" move move would be to keep the SD cards in a fireproof safe as well. I am a firm believer in having a backup to your backup.....
Now, as to the smart phones, mine is a Samsung Note 5, love it. I have all those photos stored in a Google account on the cloud ... it does so automatically and to the Verizon cloud, an option you can choose. I don't know enough about those phone, but I don't think the photos are stored on the phone itself?
The smart phone photos are so much better and accessible than the Kodak ones, but are a bit more difficult to download to this site.
There is a USB wire method and a download from the cloud method, neither of which I can remember off hand how it works.
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
