Oh I might add a little, MTP seems to be detecting the SDCard without any problem too, it's just that when I browse the folders within the device, it's not quite up there like it use to on Samsung stock rom.
Minor annoyance, but still, if there's any solution for this I'll be very thankful!
 PS : Sorry for the two post at once. My habit in other forums. Didn't mean to break the rules or whatsoever.
