iOS 9.3 Photos Features
With iOS 9.3 installed you can now duplicate photos using a built-in command in the share area of the Photos app. This works on any iPhone or iPad with iOS 9.3, and with any photo, but it is especially handy with Live Photos.
If you edit a Live Photo you lose the motion and sound while using iOS 9.2. When you upgrade to iOS 9.3, you can now choose to Duplicate or Duplicate as a Still Photo, which allows you to make edits as you need them on one of the photos and still keep the motion and sound that comes with a Live Photo.
You can also use this on videos and photos on any iPhone that can run iOS 9.3.
