@marmistrz, I tried that, several times, didnt work... :s

@nicolai. The output is from "gconftool -g /apps/camera/settings/basic-settings/storage-device" is "-1".
I dont know what it means, but I hope you do

After a Google search on internet I found that it might be a corrupt filesystem, which leads to a read only mode, so i tried to repair the FS with windows, and it helped a bit. When I first started camera-ui after the repair it worked for a second and than it gave the same error again...
Thanks
