A few years ago many wanted bigger screens so they could view web pages more easily. This included me and I bought a Note 4 and gave my S4 to my son in medical school. The N4 was hard to carry around and difficult to navigate with one hand and I began to miss the S4. Also many web sites began to have mobile friendly versions and / or apps that were easily viewable on the S4. So I went to Swappa and bought a used S4, which I now use. I can look at all the news sites I want (NYT, WSJ, Chicago Tribune, Flipboard), Android Central, Amazon, Craigslist, Ebay, my brokerage company, and many many others. I would not be surprised if there weren't a trend toward smaller screens now.
I also wouldn't be surprised of the period between purchases of new phones started to increase. I can't think of anything the Note 4 has that make it so much better than an S4. I don't really care that much about fast charging (just replace battery), brighter screen, faster processor, the Spen, It is just a fact that the incremental improvements of the cell phone are diminishing each year and there is no need to replace.
