One feature that I missed when I switched over to a Samsung is the ability to take Live Photo's with sound; I think no other manufacturer has quick movies with sound along with the photo. It would be great to take Live Photo's in 4K or 1080 - right now they are stuck at 720. You can make awesome vacation movies by combining Live Photo's in iMovie - a regular photo slide-show is just boring. This is a feature that Apple should be advertising - as it is a big reason why I came back to the Apple camp and a feature that most would really appreciate.
