Hi @Members_5PGS9O9 Have you tried resetting the settings of the USB port of your phone. To do this, go to Applications and Activate "Show system applications" by tapping the 3 lines to the right of Your Apps, select ok.
Find the USB settings app and in storage, delete the cache and data. Restart the device and see if that makes a difference.
However you may need to set a default via Developer Options? Developer Options-Default USB Configuration, Transferring Files.
If Developer options not set up Go to Settings-About Phone and tap Build Number 7 times. Will need to enter password ,Pin or Pattern at this point. See more details here: https://www.samsung.com/uk/support/mobile-devices/how-do-i-turn-on-the-developer-options-menu-on-my-....
