I downloaded and ran the most recent system update 8/11/16 (2 days ago). Everything about it seemed normal but when I went into my photo gallery all of my photos were erased! My screenshots, downloads etc. were all still there, but all of the pictures I had saved to phone and sd card are gone! I have since upgraded my cloud storage so this will hopefully never happen again but my memories of vacations, friends, places and pets are gone. PLEASE tell me someone can help!
