All my photos located in "Camera" folder are suddenely disappeared when I connect it to my PC and doing backup. When I want to copy about 50 photos from the phone to my PC folder, it is hanged and I unplug the connecting cable. When I connect the phone to pc again, the whole "Camera" folder under "DCIM" is gone. Even though I use file recovery app, I cannot find it again. Could someone suggest a way to help?
