Okay, so I've searched and found nothing similar to this - my phone deleted all the pictures that I've taken, every single one. From the SD card. I haven't done anything unusual, although the phone did a spontaneous reboot this morning. All the rest of my files seem to be there, including some desktop background images that showed up in the photo gallery - it just deleted the photos that I've taken. It's not rooted or anything, just running stock with the OTA update. WTF is that all about? I am beyond fed up with this kind of garbage.
