Turning off iCloud Photo library on iPhone
If I have used my iPhone (or iPad) to take photos and have been using iCloud Photo Library to back them up what happens to the photos ON MY IPHONE or IPAD (those were the devices used to actually take the photo) when I turn OFF iCloud Photo Library syncing in Settings? Specifically each setting a) the Photos | ICloud | iCloud Photos turning it OFF from on and also b)Settings | iCloud | Apps using iCloud | Photos OFF from on?
I need to know which method will prevent my photos from being deleted from the device where I took the photo. Please be specific as this is quite confusing, stressful and worrisome.
iPhone SE, iOS 12
