Photos taken within the Field Maps interface are stored directly in the mobile geodatabase as a part of Field Maps. In the situation where synced data is not fully transferred to the server (for any reason) and the offline area is deleted, users run the risk of accidently deleting photos or other attachments taken in Field Maps. Most of my users do not initially realize that these photos are not saved in the photo library. At either the Application level or the Map level, it would be nice to have a setting that also saves these photos to the photo library on the device as one additional level of redundancy without needing users to jump between Field Maps and the Camera app.
