In summary, the solution to transferring files by wire from the Samsung Galaxy S3 (and other Android 4.x phones) is to switch the smartphone from MTP mode to PTP mode.
The key question left, is whether we should switch the phone back to MTP mode when done; or if it's OK to just leave Android phones in PTP mode forever.
that setting only affects how the device presents itself to a USB host, it otherwise does nothing. so leave it in the mode you want the USB connection to operate in.
