When I moved my pictures from an old phone to a new phone, some of the pictures are now sorting with the date they were transferred to the new phone. This is especially true with videos. Old pictures seem to randomly appear as new pictures from time to time as well. Very odd. My suspicion is that either the file date is being used for sorting and the file date is getting reset and or pictures are being copied when they are used such as being sent in a message. I use Google photos on a pixel running nougat 7.1.2. I thought there might be a tool out there that would reset the file date time to the metadata daytime inside the picture. I have not been able to find this. Thank you for your help.
