the thing is... i only use iphone because i want some privacy.. i have been (and still) using android for many years, but too much is too much. i had oneplus one which i replaced by 6S+ just because of thinking of the privacy. i dont mean android is bad, it isnt, but however im concerned about the privacy. maybe the developers are lazy and they use things that they really dont need or they need to access for certain things, but for me it looks like they are asking just too much accessing to my private information. dont get me wrong, ios apps also do the same. however, even google wants to know everything about me (so does apple for sure!), that - im pretty sure - isnt necessary for every apps to work.
unfortunately only choice is to give up and go few years back in the tech era. i wouldnt hesitate to come back to use only android if only the security (privacy) would be better. android products are high-end devices with real innovations, productivity and usability. there is no "but" like ios has...
to me ios feels badly outdated, like a dinosaur from the history channel, but that is the price im willing to pay to get the better privacy... unfortunately. it was difficult to me to get used to the reduced win3.11 OS "feel" after android. (win3.11 because ios looks like win3.11 from 90's)
i dont even start to talk about the simplicity, because ios isnt simple at all. it is horrible when it is trying to be a simple os - it isnt. it is a catastrophe, atleast now in ios 9.1. if you got used to android, ios isnt simple. for example: filesharing, drag and drop, put a song as a ring tone, open in... if you call that as a simple procedure in ios, you are f***up!
if you want to get a better(?) privacy and be prepared to loose some controls then ios is for you. if you want to have a productivity, easily controls but willing to risk your privacy(?) then android is for you.
"if only..." and i wouldnt hesitate to sell my ios devices and running back to android as fast as i can... fully.
