Hi, I've noticed through a Google photo notification (new folder found, do you want to backup it?) that under the main folder in internal memory, there was an image not downloaded or saved by me yesterday (last modification date). Nothing strange with the image, it seemed to be a background (an autumn landscape), it was named something like login_bg etc etc and some numbers after the .jpg extension... the strange thing is that this file has not been saved my me... could the firefox browser save directly in the main folder of internal memory? Could be some app? The resolution was about 340 x 680, just a smartphone background format...
