iPhone 6S announced: 3D Touch, 12-megapixel rear camera, rose gold finish, available September 25th for $199 Apple is introducing the iPhone 6S, an updated version of its flagship smartphone with an identical design and a bundle of new features. Chief among them is a pressure-sensitive display, enabling a feature that Apple calls 3D Touch. Apple's Taptic Engine is also built into the phone to provide feedback. The features will also appear in the new iPhone 6S Plus. While the iPhone 6S maintains the same design and 4.7-inch display size as the iPhone 6, it's being offered in a new color: rose gold. It's using a new aluminum, which Apple says is its own custom alloy. And its display is now covered with a new glass, the same Ion-X that's used on the Apple Watch Sport. You can bet that these changes are, at least in part, designed to make the phone less prone to bending. 3D Touch enables two new ways to interact with the iPhone, which Apple is calling "peek" and "pop." Peek allows you to press on app icons and other buttons to pull up shortcuts directly into specific features. The iPhone 6S is also running on a new 64-bit processor, Apple's A9. As usual, Apple isn't giving the nitty gritty details of the processor, but it says that it's going to be 70 percent faster at CPU tasks and 90 faster at GPU tasks, in both cases over the iPhone 6's A8 processor. Apple is putting a 12-megapixel rear camera in the new iPhone. This is the first time that Apple has bumped its camera's megapixel count since the iPhone 4S in 2011. The camera is also now capable of recording 4K video, and it's supposed to have an improved autofocus in all cases. It also says that the camera has an improved autofocus. One thing that hasn't changed? The lens still protrudes from the back of the phone. The front camera is getting a change, too. It's now a 5-megapixel camera, and Apple has figured out a neat way of giving it a flash: the phone's display just lights up really bright — apparently up to three times brighter than it usually would. It'll also customize the color that it flashes to match the ambient lighting of the environment a photo is being taken in.
