On my Android 12 Samsung, I have no problem copying files from anywhere I
want to, and to anywhere I want to - using USB or Wi-Fi (or Bluetooth).
In my Android 12 Developer Options are _optional_ "USB Debugging" &
"Wireless Debugging" switches (both off by default) for things like adb
(which I use daily for scrcpy) to connect either by USB or via Wi-Fi.
There is an activity for "Default USB configuration" which by default has
(o) Transferring files
(_) USB tethering
(_) MIDI
(_) Transferring images
(_) Charging phone only
I have no idea even why that "Default USB configuration" even exists though
as I don't mess with it & I have no problem sliding files back & forth.
