How to recovery all of my deleted photos
Suddenly... my photos in iPhone was double,
then I found out all the photos in iPhone also in iPad.
I deleted all the photos at iPad (also the recent deleted)
but unfortunately the photos in iPhone gone too.
Is iCloud Photo Library enabled on the iPhone and the iPad? the iOS 11 upgrade enabled this by default.
With iCloud Photo Library enabled, your devices are in sync and all devices will be showing the same photos. if you delete photos on one device they will be deleted from all devices. The "Recently deleted" album is the last chance for recovery If you deleted the photos from recently deleted, they are gone.
