Talking about the design as same as iPhone 6 or iPhone 6s
the processor on iPhone 7 or 7plus is apple latest a10 fusion ship(quad core chip) 2high power cores
and 2low power cores
apple will optimize yo get great battery life and great performance
The camera on both device is 7mp front camera
but on iPhone 7 the rear camera is 12mp single camera f/1.8 aperture the sensor yo get latest and fast
and on iPhone 7 plus rear camera is same but the different on the lences, on iPhone 7plus yo get
traditional 28mm lence or 56mm telephoto lence . thats mean yo can 2x optical zoom without any quality change of picture.
You cannot get head phone jack for both devices.
apple new launche their apple airpods
on the front home button you get a 3d touch system or the display is same as previous version iPhone 6or 6s.
The device is obviously good no word to say about apple
but I think apple have to some of change on this devices apeacially about display.
otherwise a great deivice no issue
