I had about 1500 photos on my 16GB SD card, but today when I went to the stock "Gallery" I found only 880 or so. Upon using a File Explorer I found that it was still showing 1500 items but half of these items had size zero bytes. I took the SD card out of the phone and put in the laptop and it also showed the same thing. The files which have become zero bytes are in no specific order. Any help or pointers would be appreciated.
