Updated to JB about a week ago OTA. Have had some minor issues that I was able to resolve but today might be the end of my Sammy / JB experience. Tried to install my thumb drive with the usb adapter and it will no longer install. Got one of three to show up as installed in the lower right hand of the screen but after opening the my files folder it is not seen nor do the excel files show up in the office applications. Also tried 2 camera cards and they won't install either. All worked perfect before the update but not now. Anyone have a thought??? Might add, just noticed, my sdcard (internal memory - not external card) now shows up as "SDCard0" in my files. Didn't have the "0" before.
