I have an iPhone 7Plus, and I really, really like it ! I love the larger size and it can do SO much more than the older ones could do. One of my favorite things is the Live Photo, which is where the camera takes just a few seconds of video along with the still picture.
As an example, when I was at the beach at the ocean with my daughter early this month, I took a picture of her out playing in the deeper water (chest deep), and I took it just as she was about to dive under a wave.
When you play the Live Photo part , you can actually see her make the flip in the water, and of course, you can hear the ocean roaring and waves crashing in the background.
I wish the Live Photo’s could be displayed, like on Facebook; but so far, they can only be seen as a Live Photo by someone with another Apple device.
