Samsung Gallery has lost all my "favourite" images, from the SD card only. My "album groups" are now empty too, like the albums are removed from the groups. The SD card is working fine, and all images are there. I can find images I know were in favourites before. The images are there, but they're no longer in Favourites. Tagged images from the SD card have also lost their tags. Is there a way to recover the Gallery data for SD card? Please help
