I had this card I took out of my phone cause I don't use it, Until recently I did a factory reset on the phone and the SD Drive doesn't work at all.. I even bought a Brand new 8gb chip for it and formatted it in exfat32 on a window pc. Still nothing.. I use Apple Computers and I have SD formatter in both of them.. I really think its an OS issue, but you can't seem to update the OS without an SD card.. Is there a way to do an update using a mac without the SD card? I went onto LG for the Update and installed the MAc Version, however, I can't find what I installed and the Uninstall is in EXE. format... What the hell??? I know it works.. Because it used to... Any help would be appreciated... Thank you... Citizen
