One of the best mobile phone I ever use , world best selling, one of the favourite phone of all time and have the best user experience. Interface of iphone 6s is quite simple easy to use everything is on the front and more attractive because of the live wallpapers given in this 6s model and the 3D force touch which pops up every image or video when user forcely touch screen. The amazing thing about this 6s model is the response time of fingerprint unlocking. it's like a flash, took a half second to unlock your phone even if user slighly touch the button iphone unlocks.
