iPhone 7 and iPhone 7 Plus deliver an all-new Home button that uses the Taptic Engine inside your device to simulate clicks. It doesn’t actually move in and out like a traditional iPhone Home button, but that’s not a bad thing.

Not only does it make your iPhone more reliable (without a moving button there’s no need to worry about it failing), but it also makes it more water-resistant. It’s also customizable; you can adjust the strength of the haptic feedback to make your clicks more noticeable.

Here’s how.

3D Touch is all well and good, but future Apple devices may incorporate advanced haptic technology which lets software simulate textures ranging from the grain of wood surface to the cold feeling of metal.

That’s according to a new patent published today by the U.S. Patent and Trademark Office, describing a “Touch Surface for Simulating Materials” through the touch-sensitive display or trackpad of an iPhone, iPad, or Mac.
