Try to reformat your SD card but before you do so
if you want to preserve all the files from your old SD card
ok on your PC
1) open any folder -> click on tools -> properties -> view -> show hidden files
2) mount your phone with the NEW SD card and delete everything (save any file that you might want to keep)
3) swap SD cards, mount the old SD card, go to your SD card, press Ctrl + A then Ctrl C, on your desktop create a new folder, open it, then press CTRL + V
4) swap SD cards, mount the new SD card, open the folder you just created, press Ctrl + A then Ctrl C, open your SD card, Ctrl + V
like i sey before the SE app for camera have problem the ather app camera on market dont have work fine
if i delete everything from sd card is a problem? or trancfer it to my PC ?
well if you don't backup your files on your PC and you just reformat your SD card, you will lose everything thats on it
