Is it possible to connect this device to Linux workstation over USB using MTP mode? I've tried a few times using different tools but no success. GMTP just don't work, mtp-tools don't work reliably, etc.
Finally found an answer: it's not possible. Samsung implementation of MTP works incorrectly so device cannot be used in standard tools like GMTP.
Moreover, MTP application on the phone crashes sometimes during data transfer.
