I have xperia z3 for past 3 years and suddenly touch screen digitizer is gone so I had to buy new phone. Always had dream of using apple phone for past few years so finally bought apple iphone 7 32GB and the first experience of using the phone is quite good. Obviously there are few difficulties in shifting from android to ios but I felt that operating system is quite nicely optimized inspite of very less RAM compared to android phones. I particularly like the touch experience and OS smoothness. It has been quite nice phone till now. Battery backup is ok till now not sure how the battery will behave after few months. As of now, it is must try product.
