Then "preparing SD card".This happens almost everytime I awaken the phone. I picked up and "inexpensive" 16g SD card for pics and music, but it seems the phone keeps losing track of it. It just takes a few seconds and everything is fine but it's a little annoying. Is this likely an issue with the Sd card ( I have re-formatted it), or some kind of issue with the phone? what do y'all think?
