Workaround #2 worked for a bit, then failed again, this time with this "not functioning" error message. Reconnectiong the phone after changing the setting is apparently necessary. However, reconnecting again doesn't fix the repeated problem.
This is so maddening! I am disgusted with the arrogance or laziness of BOTH companies.
BTW, I've also tried transferring images by using iTunes. The instructions for that are non-existant in iTunes itself, and Apple and third-party instructions for downloading and/or synching files are about only apps, and this isn't an app. There is NO listing of files that are stored in the phone.
Why do people say Apple products are easier to use? They are NOT, and the only online Support worse is Google.
Also, newbies, please note; with earlier Windows and iPhone 4, THIS COPYING PROCESS USED TO BE A NO-BRAINER.
