I have a LG optimus q, and a 4GB SD card class 4. It started to happen randomly, when it was just sittting on the desk. Its been happening for a few weeks now, so Im not sure if it was because of a corrupt download or something. But I have deleted everything off it. and formatted it through the phone. And it still tells me that it is Blank or has a unsupported file system. I cant format it throught my laptop, because I dont have a slot for it or an adapter. Is there anything I can do to fix this? and if I must get a new one.. is there any extra steps to take before putting it in tomake sure it will work? Please HELP!
