A month ago I was like Iphone sucks, overpriced, low specs and etc. Then I listened to my best friend I bought an iPhone 6s Plus( 64GB) . Actually I realize how stupid I was that month ago. EVERYTHING IS PERFECT, I mean the battery life of the phone is satisfying, all these features are very useful, the camera is ok for me and I can say that I prefer it than any other camera as the photos look more natural and if u want better low-light photos buy the 6s PLUS as it has optical stabilization. The OS is fantastic, everything its so easy and working with icloud and iTunes is also very great.
The only thing that sucks is the 16 gigs and Bluetooth's limited sharing, but it shouldn't matter so much as there is google drive and apps which can do the work;)
O and also it's super fast!
So it doesn't really matter if you buy Samsung or Apple or Sony and etc. It all depends on your personal opinion:) And even if I preferred Android now I prefer iOS. So it's your choice:)
