I transferred fotos etc from Android 11 (Samsung S10e) to Ubuntu via USB; then, after completion, tried to unmount (I think) which then stalled (if I remember correctly) then pulled the plug and since then I can't properly mount/connect via USB again as before. - Of the USB connection options presented to me by Android, I can now only connect via "Transferring images" (also known perhaps as "PTP via USB turned on") instead of "Transferring files" (which worked before).
How to fix / reset the connection so that also the other connection mode ("Transferring files") will work again as before?
- I already rebooted both the phone and the laptop: no change.
