Recently I upgraded to the Samsung Galaxy S7. It was about $400 and it has an incredible camera; far better than my old iPhone 5s, and it looks substantially better than the iPhone 6/6s photos I have seen. Plus, it has a headphone jack, microSD support (so nice to be able to upgrade), and a really beautiful screen. Yes, Samsung installed some bloatware but some of it is actually useful (their UI for toggling radios is quite good) Android Kit-Kat is solid. To me, this was Android's first reasonable phone.
