I get the curiosity, I've been there-done-that a couple of times, but believe me, if you are an Android user who enjoys the freedom, diversity and customization Android gives you, once you use the iPhone for a week, boredom begins, you find yourself using the phone even less and less each day until you just use it when it's needed, while on Android and in a phone like the S8, months after I got it (2 months already) and I find myself turn it on just to look at the screen, then to see all my widgets information updates on the fly wherever I put them on my Home screens, changing my theme, icons and even the launcher just to refresh it, well, you know what I mean.
Once boredom hits you on the iPhone, the only ones that stays there are the loyal iPhone fans that for Apple benefit and credit, are most of them.
