MicroSD and/or internal storage of LG Optimus E615f phone doesn't mount on GNU/Linux

Yes, I do have that phone, rooted few seconds ago. Anyway, is practically impossible for me to be able to mount my MicroSD and/or phone's internal storage on GNU/Linux even if the USB mode is turn to "MTP". On my father's laptop that runs Windows, I can plug and open the folder about my phone and then select between mounting either the MicroSD or the internal storage. So, How can I mount my MicroSD or phone's internal storage on GNU/Linux?
