LOL! I just came back to the iPhone TODAY.
Like you, I got a little bored with Apple and quite frankly I get a little upset with the amount of money Apple is charging for an iPhone these days. So I sold my 6S and bought a Samsung Galaxy S6.
At first I liked it ok, but I quickly realized that I miss the simplicity, quality, and style of Apple/Iphone.
The Samsung S6 is a nice phone, but is not near as quality as my iPhone 6S. (in my opinion)
Reasons why I changed back:
1) Battery Life is MUCH better on the iPhone 6S. (there is a HUGE difference in battery life)
2) I like the Apps better on IOS. (the same apps. on android didn't operate as well as on iOS.)
3) Android phones feel "buggy" to me. (iPhone is more consistent)
4) I like Simplicity better than "bells and whistles". I don't need all of the customization, it's overrated.
(The iPhone feels like a Porsche 911 compared to the Samsung which feels like a souped up Corvette. While the stats may be similar.... the quality, performance, and feel are stronger with the iPhone.)
5) I like the email set-up on iPhone/ios much better than Android/Gmail. (even the FONT, I know... weird)
6) The overall fit and finish on the iPhone "screams" quality when compared to most Android phones.
7) I could upload photos from camera onto Craigslist directly with my Samsung S6.
8) There is an intangible "measure" that iPhone has for me over Android phones.
9) I like Apple's FONT much better.
10) Too many "moving parts" for me on Android. (Keep it simple, stupid)
11) Iphone 6S Equals "Classic" simplicity, style, and quality to me.
So, while I have a healthy respect for Samsung and Android, I had to admit that I made a mistake and went back to iPhone 6S. I had sold my 1st iPhone 64gb for $600. I bought this new one 64gb, still in plastic, for $500 ca$h. So I guess I made $100.
There are MANY souped up American made cars that have all of the "splashy" stats; however, I prefer the Porsche 911.
just my .02
