I have an iPhone 4 with 1275 photos in the "all Photos" folder. In the connected iCloud only 114 are shown. As we wish to replace the phone with a newer one we would like to save all 1275 images from the phone. Connected to iTunes about 600 are shown. All images previous to March 2015 are not shown in iTunes. Those image show a small exclamation mark in the bottom corner when looked at it on the iphone. We tried connecting to Dropbox without success. Also sending the images via email.
What can we do to save the images from the old phone?
