Following the difficulty in getting photos out of the iPhone reported here, I am now unable to delete photos on the iPhone.
Image Capture can see the photos. I select all and right-click "Delete", and it does not delete any and hangs on this visual that shows "Deleting...":
I tried deleting from the iOS Photos app. I select the photos, click the Trash icon at the bottom right, and the photos disappear from the screen. I can select other photos and scroll up and down but clicking the Trash icon has no effect. When I click the "Share" button at the bottom left, the app crashes. When I relaunch it, the photos I deleted are still there.
The behaviour is the same after restarting the phone and restoring the firmware and a backup.
I already transferred the photos and videos. I would face this problem for each new photo and video I take, and soon I would run out of memory.
How can I reset all photos and videos in the app without losing other data such as messages and call logs?
