Well I own an iphone 6plus I am having its 64 gb version, according to me apart from its expensive price everything is smooth and wonderful,
Just because of its smooth performance half of my work is now I am doing with this phablet only, screen is super clear, and obviously the touch is fantastic and talking about the camera you can easily compare the photo clearity by any professional camera, you can run many apps without any lag thats the most plus point,
Screen is user friendly too, talking about the security well the touch id recogination is superb,
I tried other new features of this phone like touch id etc.
its 4 months now only but Im totally happy with my iPhone 6 Plus and would recommend it to everyone.
