When I browse my device (Motorola, Android 7) using Dolphin, I cannot see the subdirectories neither the ones of the internal storage (/run/user/1000/aa321541a9e62340/storage/emulated/0/) nor of the SD card (/run/user/1000/aa321541a9e62340/storage/6365-6131/). However, when I manually enter a subdirectory's name I know exists (e.g. /run/user/1000/aa321541a9e62340/storage/6365-6131/Download/), I can see its contents and browse its subdirectories without problems. When I do an ls on one of the unbrowsable directories, I get: ls: reading directory '/run/user/1000/aa321541a9e62340/storage/6365-6131': Operation not permitted The generic links to the pictures, both on internal and external storage, work as they lead to subdirectories.
