iPhone 6s introduces an entirely new way to interact with your phone. For the first time, iPhone senses how much pressure you apply to the display. In addition to familiar Multi-Touch gestures like Tap, Swipe, and Pinch, 3D Touch introduces Peek and Pop. This brings a new dimension of functionality to the iPhone experience. And when you use 3D Touch, your iPhone responds with subtle taps. So not only will you see what a press can do - you ll feel it. Peek and Pop let you preview all kinds of content and even act on it - without having to actually open it. For example, with a light press you can peek at each email in your inbox. Then when you want to open one, press a little deeper to pop into it. iPhone 6s and iPhone 6s Plus take everything that made the previous-generation iPhone great, and advance it to a new level. They re made with 7000 Series aluminium, the strongest alloy we ve ever used in an iPhone. They both feature Retina HD displays made from the strongest cover glass used on any smartphone in the world. And now they re available in an elegant rose gold finish. The iPhone 6s enclosure is made from the same grade of aluminium used in the aerospace industry. It s created from a unique composition of elements that make it the strongest alloy we ve ever used in an iPhone. The new glass on iPhone 6s is made using a special dual ion-exchange process, which makes it stronger at a molecular level and the most durable in the smartphone industry.
