Hi I'm new to android tablet. I have a mg638 2.2 tablet. I am trying to transfer music to my tablet from my pc. I have transfered the music by usb stick, and it appears in the devise ok,but I can't seem to store it on the device. The instructions are - tap on the ikon to display contents of usb, tap and hold in the file you want to copy,tap copy, tap on the internal memory, tap on the folder into which you want to copy the file, tap paste. Well, I can follow as far as "paste", but where is "paste"? how do I find it? help would be appreciated, as I seem to be completely missing the last step.
