HELP PLEASE: Pictures taken over the weekend have disappeared :-(

[AndroidLo]

Hi I spent the weekend in a place with no connectivity so could not back up my pictures.
And, all those which were not backed up are lost, well, all but the very last I have taken.
How is it possible that only those pictures were deleted, and not all the previous ones, which had been duly backed up, is a mystery….

Hi. What type of phone do you have. Can you connect it to a pc and find a DCIM folder.
