Never Let Support Agents Backup the Photos on Your Phone
If you bring your Android phone for servicing, never ever let support agents take care of backing up your photos or data for you. Instead, make sure the photos are safely in the cloud or offline somewhere other than on the device. If you have the Google Photos app use a computer to visit the photos.google.com website and double-check all the photos are there.
In the official Google Photos Help Community I’ve seen too many reports of users whose photos were supposedly “backed up” by a repair center’s support agent, yet went missing after a factory reset.
