Finally, I had to seek help on the web, and someone suggested to modify a certain option in the Settings menu, and see if it will make a difference. It didn’t take long before I figured that the problem was within the phone itself, and not PCs nor cables. In some cases, this actually helped both for above mentioned cases when iPhone wasn’t showing allow access prompts when connected via USB cable and when copying some of the problematic folders (but not always)! This absolutely didn’t have any positive effect on the issue at matter.

I switched to a brand new original iPhone USB cable.

Switching computers apparently didn’t help fixing the problem.

I tested iPhone connected to three different PCs (Windows 7, Windows 8, Windows 10).

All 3 of them manifested same problem, which appeared to be erratic, as each time, copy process was stuck at a different image or video file. Three different PCs in total were changed running Windows 7, Window 8 and Windows 10, respectively. Couple of times, after several abrupt USB cable connect/disconnect cycles, iPhone no longer started showing prompt to allow access to media files!

Or, when I was finally loosing my patience and manually disconnecting phone’s USB cable, messages reported in those cases were expectedly different: the device is not available or the device is disconnected.

Sometimes, the error occurred right at the start of the copying procedure, sometimes it happened in the middle, and Windows was just hanging there for a while, until finally reporting that the connected USB device is not functioning. However, that’s where the issue started to appear. In the beginning, first couple of 1xxAPPLE folders were copied without problems (e.g. How To Fix USB Device Connection Errors and Image/Video File Transfers From iPhone To Windows Computer? And that’s the exact moment when our agony started… Instead of copying all the images and videos to the new device, she decided to simply create a backup of the entire DCIM folder on her Windows PC.

Recently, a friend replaced her aged iPhone 7 (which she only bought last year!) with a newer model from the X series (iPhone XR – very similar to iPhone XS, but with a larger screen/body, lower display resolution and no telephoto camera), and decided to start afresh with her shiny new phone.
