I purchased iphone 6s 3 months ago and from the day my life changed this phone is too good it is fast responsive it never changes it has a great interface.
The best part is that it has got a new feature the 3 d touch this 3d touch creates an all-new experience which differentiates it from all other phones.
It also has a great new feature of live photos which is not present in any other phone this live photos can also be put as wallpapers and they are called live wallpapers.
