We will never again see the days of the first couple iPhones where minimal features lended themselves to a minimal UI and well. It is the way it is. Following iOS 6 and 7, Apple had two choices:
- Stay the course with the simplest UI and minimal features and be buried by Android (and if you don't think that's true you haven't been paying attention to verbal customer demand, which includes jailbreaks and all the rest)
- Add features, which eventually WILL add complexity to the UI, but still do things the Apple way (people complain night and day about the lack of a "proper file system", which ironically would drop the intuitivity level by a great deal if it were a part of iOS)
I just don't see another way to do things. It's almost 2016. Some of their individual software needs to improve, there's absolutely no doubt - eg iWork - but generally I do feel like iOS as a whole is doing a great job considering all the iPhone can now do.
