Have a Samsung Moment and I've tried three different SD Cards, and the phone simply says " SD Card Removed, Please Insert SD Card "..even though their is a SD Card in..Help?
Well you can try reformatting the card while it's inserted in your phone and see if that works, just make sure that any media or other files you may have on it are back up first so you wont loose anything
Well that is really weird, if you have and SD card adapter and a computer with an SD card slot try formatting it through your computer and re-inserting it back into your phone. If that doesn't work you may want to wipe your phone.
