About a year ago I got a new phone and used smart switch to transfer settings etc from my old Samsung smart phone. Since then, whenever I delete photos that were part of the transfer they keep coming back every few weeks. I do not have any back up settings (eg one drive) set up, except Google Photos, but at these were originally WhatsApp photos they were never backed up to Google Photos. In addition, I have no back up settings with WhatsApp, so they are not backing up from there either. I also have no SD card. I'm absolutely baffled as to how to get rid of these photos without putting my phone back to factory settings
