I can’t drag my photos from Galaxy S8 to PC. It used to work. The error occurs on multiple PCs and different data cables. The USB option “USB Data Transfer” is of course always adjusted accordingly.
I’ve been using Android /e/ for several years and it always works.
Which error exactly?
Are the files visible to the computer and an error occurs while copying them, or are the files not visible to the computer at all?
Which OS are you using on the computer(s)?
Do you mean the setting which you can access via the notification when the phone gets connected, or the often mentioned connection mode preference setting in the Developer options?
