If you experience that your phone’s storage content (internal and/or portable sd card) on a windows (10 or 11) pc is not shown and you already checked
- use 2 diffrent cables
- ensure that you selected “data transfer”
Test it with another pc, when it is working there it has something to do with the pc.
In my case I have installed earlier the Android (Nexus) ADB drivers - these made no trouble with former Android 9 & 10 (Samsung phones). So uninstall the driver from hardware manager. (I did while the phone was connected so they are easy to identify). Afterwards unplug the phone and replug.
Wohaa: After selecting “data transfer” FP4 content was shown.
Additional hint: You might recognize that your “driver” is out of date if windows shows the phone as usb device that you must “remove/disconnect/exit” (so the usb icon shows up in taskbar). For actual drivers this would not happen because you can unplug at anytime (of course not while e.g. transferring data )
