Your comment doesn't really disagree with theirs. One major reason Android feels so fragmented is all the different devices. My last Android phone was an LG G3 (yeah I know I'm out of date nowadays). It had a really good camera (for the time) with a fast laser autofocus. Turns out no app used the proper APIs to take advantage of laser autofocus. If I wanted to take a picture with an app, I would have to take a picture with the camera app, and then upload it. Except certain apps like Instagram didn't allow you to upload photos from your camera roll, so any instagram photo I took was not in focus.

In my opinion iOS was far better when there were fewer different devices released every year, but it's still better today than Android.
