It's a great phone with 256 massive space and 3gigs of ram.
It has dual rear camera each of 12 mp one is wide lence and other is micro lence which helps us to zoom in without affecting the quality of photo and front camera is same as iPhone 7 which is 7 mp
It also have didn't have the press able button now it is press sencitive
It is also more bitter then iPhone 6s
It also didn't have 3.5 mm headphone jack instead it give a light converter which converts 3.5mm jack into lighting port
Allover it is great phone by Apple but over priced
