I just switched over from the iPhone 4 to the Galaxy S2 LTE so I am still completely unsure what anything is at this point. My questions is about the available memory display in the task manager. Mine shows how much memory is used on the 32gb Micro SD card. It also shows how much of the phone's built in 16gb memory is taken up by various other things like apps which all makes sense to me. Where I am getting confused is there is also a graph showing how much of the "USB memory" is being used however, not only do I not have a USB drive currently connected to the phone but to my knowledge a USB drive has never been connected. Am I missing something? Any help would be greatly appreciated!!!
