I did the support update last night, which was basically nothing. my tab came with jellybean installed (I hadn't realized!) and I had been ignoring the update because I didn't want to update versions of android. I did that once already on my phone and wasn't happy. Anyway, so once I realized it was a samsung update and not an android update, i ran it. the only thing i notice different is now it won't read the SD card. it had said "damaged SD card". I have barely nothing on there, so I don't care if it formats, but it won't format through the Tab. I formatted it on my computer, which reads it fine. then i put it back in the Tab and it says "Blank or unsupported SD card." What causes this and can it be fixed? thanks!
