i just bought a lg cosmos 2 and i am trying to transfer pictures from my computer to my phone via usb cable. when i go to my computer and click on the external drive, my phone beeps and says no sd memory card then the external drive is no longer available. i should have enough internal memory to transfer pictures, right. also, how do you delete factory installed pics. i have tried using the picture manager but when i click on erase it says no picture is selected. however, i have selected a picture. can anyone help me out?
