Last week i took some pixs and vids with this phone-later i found none of the vids in my gallery or folders .The pixs were there though Today took several pixs and videos - and none of them are in my gallery They go onto my SD card and there is 9gb of free space
Do you by any chance use Picasa Web Albums? It has been known to cause issues with pictures disappearing from the phone's gallery. Try navigating to Settings > Accounts > your Gmail address and temporarily disable Picasa. Restart your Galaxy and see whether the pictures reappear.
