Hey all, just had this happen to me. All I did was switch the saving of pictures and videos from device to storage card and EVERY picture/video was deleted from just that day. All my music and previous pictures/videos were fine....none of my music is from the sprint store just in case any one thinks that's the relation....hope there's a fix soon....
Oh and as a side note....the card's memory is showing that it's being used...like as if those pics/vids were still there....not sure if any one else is having that same issue.
